for every Amiga developer to pull together and present his very best products for the Amiga. But this docs not mean that other groups cannot demonstrate the capabilities of the Amiga. Although it will be presented without corporate support from Commodore, AmiEXPO, Inc. is still planning their event in Long Beach from February 14-16. This is what the Amiga is about. It is an independent tool for a group of very independent people. The enthusiasm for the Amiga cannot and should not be confined to just two out lets ea ch year. Nationa l Amiga shows are important as a showcase for the Amiga to the rest of the nation, but Amiga enthusiasm should not be confined for those expositions alone. it is also possible for user groups to create Amiga events. These events can include other user groups, Amiga dealers, local developers, and more. It might even be possible to put together seminars and even speeches by Amiga celebrities. Anything that enhances the image of the Amiga and allows its users to gain enjoyment, insight, and interest in this computer should be explored.

Tel. (215) 337-8770 • FAX (215) 337-9922 Amga s a regislwoO traden-mrv o Corrmxtore¦ Arr-ja, Inc 11991 Groat Vatey Products Inc. Dear AC; I read the January issue regarding Amiga shows and worldwide attendance. I believe there is niore to relatively poor U.S. show patronage than "too many shows 'especially when compared to European shows, such as England's. U.S. shows, no matter who conducts them, are usually held on the Coasts or in Chicago and often nearly simultaneously. I have yet to see a show in Dallas or New Orleans, for instance.
Also, 1 01 tr magazine stated that there are about SOU K Amigas installed in Britain. Good grief, no wonder they had a huge turnout for the London show! All of Great Britain is smaller than Colorado, and my guess is I here are not 800 K Amigas west of the Mississippi.
You still put out the best Amiga magazine in the States and seem by far and away the most reader responsive. Thank you.
Sincerely, Barlow Soper, Ph.D. Professor Ruston, LA Dear Dr, Soper: Thank you for your kind words and interest. Your comments are well informed and your arguments are well constructed. Although I disagree with your conclusion, I am in firm agreement with your arguments. How is this possible? I believe we are arguing for the same thing, but in different perspectives. Allow me to explain Recently, the local model-train club, Old Colony & Fall River Railroad Museum Inc., held an exposition inviting train dealers, rail fan clubs, and the general public. It was a one day event, held on a
Sunday from 10 a.m. to 4 p.m. 1 had seen a small ad for the event in the local newspaper and decided to hurry down early Sunday morning.
When! Arrived at 10:15, three large parking lots were already full. When I entered the gymnasium, 1 saw a throng of enthusiasts milling about the different tables. There were dealers from around the region selling rolling stock, scenery, kits, etc. It was easy to begin a layout just hv shopping those aisles. There were hobbv shops, as well as collectors who wanted to sell or trade equipment.
After an hour, 1 had just been able to make mv way through the crowded aisles once and had seen only about half of the things on display.
I decided that the best way to enjoy the show was to return when the crowds had died down.
Before 1 returned,however, 1 called a few friends to tell them about the show. Then I picked up our advertising manager, Wayne Arruda. There still was no parking close to the show, when we arrived at the event at 1:15, and the crowds, although slightly thinner, were still interested and enthusiastic. We spent an hour and a half reviewing the layouts and the displays, and 1 spent some hard-earned money on some Iwd-to-find pieces and used equipment.
By then the crowd had diminished so that it was actually possible to talk with the dealers.
As we were leaving, we saw Jeff Gamble, AC's associate editor, arriving. 1 had decided to take Wayne home, as he had an important basketball game to watch, but 1 returned to the show. Yes, once back, 1 boughta few more pieces, but I also saw some things! Had not seen before, In short, my point is, not only had the show excited me and many others, hut my enthusiasm had attracted two more people.
Now, you may ask, what does this long- winded explanation have to do with Amiga events? My questions and comments in the January issue were focused on what I believe is necessary in the U.S. Amiga market to put on a successful national event. This has nothing to do with local events supporting the Amiga.
Since the editorial ran, 1 have received two letters: yours and an equally good letter from Mr. Ronald Accardy ("Feedback," p. 79). Although these are the only letters I have received on the matter, they carry' a very similar viewpoint, It is a long-standing axiom in publishing that for every letter received there are thousands of other readers who hold the same opinion. I believe your concerns need answers.
A national Amiga event is an event created for developers and Commodore to announce new products, gain interest, and receive maximum press exposure. Companies plan strategies for attending the event. These events are held on either Coast to entertain different segments of the press as well as equalize the transportation costs for exhibiting companies.
U. S. Amiga developers, for the most part, have long ago decided
to attend only a few Amiga shows given each year. This is why
the events have appeared small. This is also what prompted
Amiga developers and Commodore to search for a possible
solution because the current show policy was not working. What
Commodore has done is to provide a time and a place that every
developer can depend on to give them the maximum exposure.
Commodore did not need to look far: they only had to see the growth of MacWorld EXPO, held twice each year on both Coasts since 1985, to see what the right planning can do to improve an event. The first MacWorlds were small, but almost all vendors made it their business to attend. Tire show grew in size as well as in press coverage. Now a MacWorld can take over San Francisco or Boston, but all developers understand tha t i f they want to he taken seriously, they must attend the event. MacWorld has even announced a third show in the U.S. this year.
The April 24-26 World of Commodore in New York is the first time we have had the same opportunity, itisan opportunity for every Amiga developer to pull together and present his verv best products for the Amiga. But this does not mean that other groups cannot demonstrate the capabilities of the Amiga.
P. S. Thanks for your comments on the magazine; however, we
believe you wit I soon sec A ni a zingits not only the best in
the States, but also around the globe.
Although it will be presented without corporate support from Commodore, AmiEXPO, Inc. is still planning their event in Long Beach from February 14-16. This is what the Amiga is about. It is an independent tool for a group of very independent people. The enthusiasm for the Amiga cannot and should not be confined to just two outlets each year. National Amiga shows are important as a showcase for the Amiga to the rest of the nation, but Amiga enthusiasm should not be confined for those expositions alone.
It is also possible for user groups to create Amiga events. These events can include other user groups, Amiga dealers, local developers, and more. It might even be possible to put together seminars and even speeches by Amiga celebrities. Anything that enhances the image of the Amiga and allows its users to gain enjoyment, insight, and interest in this computer should be explored.
It is important to remember that it will not be possible for these events to be supported by every' vendor and Commodore. When these shows occur, remind the attendees that it is a local or regional event supported by regional groups. This way everyone wins and, as long as everybody understands what to expect, there will not be the disappointment we have witnessed until now.
The Old Colony exposition brought 1600 people togetherona pleasantSunday in January.
Although a collection of people from different backgrounds and interests, they all shared an enthusiasm for trains and enjoyed the opportunity to come together and have fun. No one asked where the major manufacturers were. No one expected 50 or 60 vendors to be present to announce new products. Dealers ran videos, sold prod ucts, and met customers. For part of a day, a group of people enjoyed themselves.
How can we make this type of show possible for the thousands of Amiga enthusiasts spread around theU.S.nnd theother user groups around the world? It will require cooperation and a realistic vision of what shou Id be expected, butitis possible. Ivvillaskall Amiga user groups throughout the world to contact us with their ideas. National shows are important as a showcase for the Amiga to the rest of the nation, but it is the Amiga users who can do the most to entice the public to the benefits of the Amiga.

Is a high power Amiga® 3000 3000T user you need a 68040 accelerator board for one reason ...and one reason only... SPEED!
? 0 to 8MB of onboard, 40ns, non-multiplexed, DRAM.
Fully auto-configured, user-installable SIMM modules lets you expand your A3000 to 24MB!
? DRAM controller design fully supports the 68040 CPU's hurst memory access mode.
And once you know what makes one 68040 accelerator better than another, the only board you'll want is the G-FORCE 040 from GVP.
WATCH OUT FOR SLOW DRAM BOTTLENECKS Yes, all 68040 CPU's are created equal but thisdoesn't mean that all accelerator boards allow your A3000 to make the most of the 68040 CPU's incredible .performance. The A3000 was designed to work with low-cost, 80ns DRAM (memory) technology. As a result, anytime the '040 CPU accesses the A3000 motherboard, memory lots of CPU wait-states are introduced and all the reasons you bought your accelerator literally come to a screeching halt!
Not true for the G-FORCE 040... SOLUTION: THE G-FORCE 040's FAST, 40ns, ON BOARD DRAM To eliminate this memory access bottleneck, we designed a special 1MB, 32-bit wide, non-multiplexed, SLMM module using 40ns DRAMs (yes, forty nanoseconds!). This revolutionary memory module allows the G-FORCE 040 to be populated with up to 8MB of state-of-the- art, high performance, on-board DRAM.
Think of this as a giant SMB cache which lets the '040 CPU race along at the top performance speeds you paid for.
SHOP SMART: COMPARE THESE G-FORCE 040 SPECS TO ANY OTHER '040 ACCELERATOR 68040 CPU running at 28Mhz providing 22 MIPS and 3.75 MFLOPS!
NOTE: The 68040 incorporates a CPU, MMU. FPU and separate 4KB data and instruction caches on a single chip.
? Full DMA [Direct Memory Accessl to from the on-board DRAM by any A3000 peripheral (e.g: the AAOOO's built- in hard disk controller).
? Asynchronous design allows the 68040 to run at clock speeds independent of the A3000 motherboard speed.
Allows easy upgrade to 33Mhz 68040 (over 25.3 MIPS!) When available from Motorola.
Hardware support for allowing V2.0 Kickstart ROM to be copied into and mirrored by the high performance onboard DRAM, Its like caching the entire operating system!
Software switchable 68030 "fallback mode for full backward compatibility with the A3000's native 68030 CPU.
? Incorporates GVP's proven quality, experience and leadership in Amiga accelerator products.
TRY A RAM DISK PERFORMANCE TEST AND SEE FOR YOURSELF HOW THE G-FORCE 040 OUT PERFORMS THE COMPETITION Ask your dealer to run any "RAM disk'' performance test and see the G-FORCE 040's amazing powers in action.
So now that you know the facts, order your G-FORCE 040 today. After all, the only reason why you need an '040 accelerator is STEED!

REVIEWS T( you're like me, you have a favorite pair of old shoes, and no matter what happens,you refuse to throw them out. So, you may take them down to the neighborhood repair person to see if they can be stitched up just one more time. Now, imagine that when you get them back, they look and act like the shoes that Spock wore in Star Trek V, shoes that allow you to fly. If you can imagine the wonder and joy you'd feel, wearing something very comfortfirst Dpaint offered an easy to understand toolbox with all of the standard tools needed to address real electronic painting on the Amiga;
Dpaint II offered undreamed of perspective modes that added 3D depth to 2D work; Dpaint 111 gave us ANIMbrushes, and allowed me to do a whole series of animations for regional broadcast using just one program, from drawing to animation; and now, in the center ring...DPaint IV!
ELECTRONIC ART S' DeluxePaint IV: Retrofitting your favorite shoes.
R. Shamms Mortier able that takes you to new heights, then you
will get some idea of how DeluxePaint IV from Electronic Arts
compares to its comfortable parents. It's certain that for
most Amigans, EA's Dpaint scries has al! Of the cozy
attributes of well worn sandals. That's because we know it so
well. The toolbox is almost second nature, something we don't
have to think much about when we create 2-D images. The feel
of Dpaint is pretty intuitive by now...so, why would EA want
to change it?
Well, the answer is in part, because we clamored loud and long for them to do so. The Amiga graphics universe isno longer what it once was, but has become the playing field for 24-bit overscan images and associated paint programs. You have to at least address HAM modes to remain a serious player, and unique tools and toys don't hurt your chances either. Back when many of us purchased Dpaint I, the only serious competition was Aegis Images (still available for about $ 40.00 from Oxxi Aegis). I still remember the creative thrill each new up- gradeofthesoftwarebrought:The What’s New By now,
most Amigans are familiar with oneor another Dpaint release. Some folks are even hanging onto their Dpaint I disks, afraid that an update will throw them into unfamiliar waters. Well, that may be so, but the "throw" will lie a gentle toss,beca use E A has wisely kept most of the toolbox and the icons the same throughout the four releases. Yes, some things have changed over the years, like those Figure 2: Morphed series of animation frames.
Items mentioned and things like true overscan painting. But, by a nd large, owners of an f earlier version of Dpaint should update their disks as soon as possible, just to have more challenging creative enjoyment if for no other "professional" reason. Considering that most Amiga people are aware of thestandard things an Amiga paint program does (and EA has set and maintained this standard themselves), 1 am going to focus attention upon tire new and wondrous tools that come with the release of Dpaint IV. Allow me to list my choices as the most important things that I think Dpaint IV
adds to your repertoire of creative Amiga alternatives, reasons that you should upgrade to Dpaint IV if you have an earlier version of it or reasons you should consider purchasing it for the first time: Now featuring HAM painting modes, "Light Table", and new Palette and Range options.
1. The addition of hi AM painting modes (in full overscan)
2. The set of new color-fill options
3. The "Metnmorph" capabilities
4. The new Palette and Range options
3. The "Lightablc"
6. It's capabilities as an editing station for DCTV To be sure,
there are other resident new changes as well, but I consider
these to be absolutely primary.
Caterpiilars to butterflies, tadpoles to frogs, ail this is possible with Deluxe Paint IV, HAM Dpaint IV uses a HAM palette of 256 colors out of the total 4096 colors. Don't feel cheated by this. It's seldom that you use more then these many colors in HAM anyway, and if you need to, you can always port your HAM artwork toNewTek's Digipaint Hi or Oxxi 's Spectra Color, both of which offer all the colors in the HAM rainbow. Then why bother about HAM mode in Dpaint anyway, if there is other software capable of more HAM colors? Dpaint's 256 color HAM mode is more artifact free then other HAM
painting programs. It is always computing the best dither range per scan line, which you can see happening when you move a brush across a HAM Dpaint IV color background.
This means sharper and less artifacted-fringed images. Besides, Dpaint offers oil of the familiar tools it has made standard painting options in its 11AM mode, including powerful and easy to use fill routines. Dpaint Is useful as a starting point even when other paint programs are used to give your 11AM work final touches, or it can be used a the final touchup option itself. Just try and find the same options for filling a shape or 0 ¦ ¦¦¦¦¦«¦ ¦ m ii stjKffwlwlwlwtsfi*!&iwiwi w|t- +

of the HAM painting options in Dpaint IV work flawlessly.
Ownersof Dpa int I! I will recognize on I y ha I f of the opti on s now present in the "Fill Type" requester, the other five directional choices are brand new. Though these directional dithered fills can be utilized from any Amiga resolution, thev realty shine in the HAM modes. In addition to the recognizable Horizontal, Vertical, and Horizontal Shape toolsare five new selections. The first two are "linear gradients", LINE and SHAP (SHAPe). These allow you to determine the actual direction of a dithered fill in a dosed shape, and bring up a user placable directional line so that this
is accom- plished graphically. Next are the three "radial" gradient tools, CIR(CULAR), CON(TOURS), and HI( LIGHT). These add a crosshair after the directional line so you can determine the lights apparent "hotspot" as well, and it is very important at which point you determ ine th i s hotspot is to be placed.
They differ as to how the overall shapesaredithered and smoothed out (See Figure 1 for graphic comparisons). If you are in HAM mode, these fills are seamless and exact, if not, the dithering is more apparent between certain colors.
New Deluxe Paint IV Palette and Range requesters.
There is a new box in the requester that allows you to choose various color ranges that have been preset beforehand. This is how colors in the gradient fill tools are determined.
Meiamorphing Caterpillars to butterflies, tadpoles to frogs, Neanderthals to Homo Sap tens, calm friendly faces to Werewolves, all of this and more is possible with Dpaint IV. If vou love Amiga animation and or need to access it professional!}', then you will absolutely flip for the new Morphing (Metamorphing) capabilities of Dpaint IV. "Morphing" means that one shape is changed to another over a series of steps or frames, and Dpaint IV allows you to select any two brushes as start and end points of a morph, and creates an ANIMbrttsh automatically between the two in a user selectable number
of frames. This is not the way to crea te anima ted f i gu res like running gazelles and such, but a way to transform unlike objects from one to the other. Lettering can be translated into graphics figures, for instance (a great way to develop learning modules for primary' readers!), and also a wonderful new tool in the generation of ANIMfonts! If you are working in non-HAM modes, thecomputer even i nterpolates w ha t palette colors might look best in the transitions from one to another. In MAM modes, the same is true, but the color transitions are smoother. The look of a morphed
ANIMbrush is likened loan object that achievesa chaotic state before reaching its goal, and it is visually most interesting to behold. See Figure 2 fora sample of what a morphed series of animation frames might contain.
Palettes and Ranges These requesters are completely new, and they replace the oncstandard requester that represented them both in Dpaint IQ.
When in HAM modes, the palette requester allows you to set colors for sixteen separate and identifiable color ranges, each of which contains sixteen colors. Limiting the number of HAM colors is a tremendous aid in getting a clean HAM output. All of the standard color change tools are here: RGB and HSV sliders, "Copy", and "Exchange". In addition, a hove the Color pots, is an area dedicated to setting specific dithers between colors, each of which has a number "tag" that can be accessed in the Fill requester. Rough results are obtained in non-HAM modes, but HAM painters will notice dithers
as smooth as silk. Setting color "ranges" for color cycling and other dithered effects is accomplished in a separate "Range" requester in Dpaint IV. Color cycling animations are benefited by the new possibilities in this tool, both in terms of the possible complexities of ranges and their number. Finally the ability to do controllable color cycling in HAM!
The Light Table An "In-Between" or "'Tween" drawing is an animation frame that is drawn between one important (keyframe) drawing and another. Sometimes there are dozens of tweens between keyframes. As an animator who has drawn these by hand, I can confess to their tedious and frustrating nature. If the tweens are drawn out of place or too roughly, there is a perceived jump in the playback of the animation. Animators usually draw "pencil tests" of their animations on thin tracing paper or vellum. Each drawing is placed on a table that has a frosted glass cover, underwhich isa light.
These "Light Tables" allow you to see the last frame drawn, so that the next one can be drawn in its proper place. Dpaint IV has incorporated the idea of the Light Tabie in the software, allowing the Amiga animator to drawn Disney style movements from one frame to the next. The operation of the too! Is simple, it can be toggied on and off by tire keyboard comm and "I" (lowercase "L"). When in operation, you can advance from one frame to tire next, always seeing the preceding one, so that accurate new frames can be designed. This is also a great way to touch up an already existing
animation. The best way to utilize this new feature is to work in two color mode, drawing only the outlines of your animation. After saving this to disk as an animation, load it into a full color screen and paint in the frames. This is the way traditional animators work.
DCTV Dpaint IV is probably the best utility tool for Digital Creations DCTV hardware and software, because you can use it to take DCTV single frames and combine them into either whole or segmented animations. I use it exten- sively with ADSPEC Programming's Draw-4D Pro in this manner, and also to preview DCTV animations from other sources. Dpaint 111 did this as well, but refused to load animations larger then the screen size. This restriction is no longer present in Dpaint IV, although it will seemingly cut the left and right edges off of an animation larger then the screen in order to be
able to play it back.
The Manual as Art!
I believe that you can tel!
Something about a book from the condition and design of its cover, and especially the condition and value of Amiga software from the state of ihe manual that accompanies it. If care is shown in one area, ii most likely designates care in others. Electronic Arts started the Amiga tradition of designing beautiful manuals to accompany the software they released, and nowhere is this made more evident then with Dpaint IV. Even the absol Lite Amiga novice should be able to apprecia te the clear tuto- rials, crisp screen shots (some in full color), and step-by-step caring walk-throughs that the
Dpaint IV manual bulges with. The manual deserves separate and worthy praise, and should be a model for all other serious Amiga developers.
What i would like to see in Dpaint V Dpaint IV is a high class act, and as such, has set the standards that it too must follow in its own future development. My suggestions as to future enhancements are based in part on present need and in part on pure tust. Realizing that, here they are:
1. The ability to at least save in 24- bit format. Actually, I'd
like to see a Dpaint 24-bit painting and animation program
2. The ability to save in DCTV format.
3. Amore antialiased circle ellipse generation in HAM (with
results more like NewTek's DigiPaint 3).
4. A "Half Horizontal" and "Half Vertical" capability in the
Brush sizing requester.
3. More resizing and modifying capabilities for ANIMbrushes.
These are only suggestions, and in no way effect my feeling that Dpaint continues to be the most generally useful software for the Amiga artist and animator.

innovative new way to learn piano and keyboard playing without
So, I drive up to my favorite Amiga dealership, and there is this big banner in the window..."The Miracle is Here!" It was close to Christmas, but 1 knew this wasn't an exaltation of the true meaning of the Season, nor had the place gone beilv-up and become a religions bookstore. No, the banner touted a device I had been waiting for since 1 bought my Amiga 500, and Deluxe Music Construction Set, 5 years ago. Or, more truthfully, 1 had been waiting for it for 30 years.
"The Miracle" is the Miracle Piano Teaching System, a hardware software instruction combination that, with your computer, teachesyou how to play the piano, at a list price of $ 479.00. Created by The Software Toolworks, it is advertised on national television as being compatible with Nintendos, PC's, and the Amiga!
Not only was lire Amiga considered in the development of this product but, to my knowledge, this is the first time a third-party developer has mentioned the Amiga in a television ad.
It should also be mentioned that the software was developed for the Amiga by our friends at Blue Ribbon SoundWorks, Ltd.
While the look and feel of the program are very different from the Bars & Pipes line, il is apparent, for reasons I will discuss later, tha t this program was influenced by people who know and love the Amiga.
THE SOFTWARE TOOLWORKS' Miracle Piano Teaching System by Christopher Piper The program is laid out likea conservatory of music, with a classroom, practice room, concert hall, recording studio, administration office, and even an arcade game room. When you enter the program, you start at the administration office to log-on,or to register asa new user. You will then be asked if you would like to continue where you left off the last time, or go to the main menu.
An overhead view of the conservatory serves as the main menu. Click on the room you wish to enter, and you are presented with the options for that area. In the concert hall you can choose any of a hundred songs (more available separately) to play, accompanied by a MIDI (Musical Instrument Digital interface) orchestra. You can also make your own MIDI recording, with up to eight instruments, in the recording studio. Most of your time will be spent in the classroom and practice room, but you will definitely spend a iot of time in the arcade, as well. If you work hard, the Administration
Office will print a "Certificate of Merit" for you on any preference-supported printer.

Like a typing program, the Miracle System sets up a course of study based on the student's ability' and progress. Lessons and exercises are tailored to strengthen weaknesses determined as the program "listens" to your playing. Your performance is evaluated, corrections suggested and you are given exercises that will promote those corrections.
Lett; The Miracle welcome screen.
Above; "RipChord", a musical game which teaches note and key association, Perhaps "exercises" is too strong a word, as it calls to mind something more like work than is actually the case, if you screw up, then you get to play arcade games like "Ducks". This exercise (read game) strengthens your ability to recognize individual notes and chords on a staff. Ducks travel along the staff and, if you hit the correct piano key, they quack (on pitch), spin and disappear. Otherwise, some nondescript muck splats on the staff where you "aimed."
Another game, "RipChord," features an Air Show in which little parachutists jump when their assigned piano key is struck. Strike a 11 the correct keys simultaneously to form the appropriate chord and their chutes open and they finish the act. Misplace a note and the act falls flat...literally!
These games, and my favorite "Aliens" ("Close Encounters of the M usica I Kind"), are lots of fun, but they do not completely take the place of conventional practice.
Fortunately, practice is almost as fun as the games. Almost. The sheet music appears right on your Amiga screen. It is highly legible, and takes you through the music in two ways: Hesitation mode lets you take your time positioning your fingers to form chord and find the melody. Once you have played the proper notes, the cursermoves on to the next position. Since you can take your time, the "teacher" is less forgiving of misfingering. If you are sloppy, you will be kept after class to practice; Metronome mode lays down a beat to which you must play.
You are taken through a piece phrase by phrase, slowly at first, until vou can play the full score at the proper pace. Small hatch marks over the staff denote each beat, and disappear at the appropriate stroke of the audible metronome.
An arrow also marks your current position in the score. The program can recognize phrases in which you have had some difficulty, and will go over the phrase with you until you improve.
Difficulties with rhythm are addressed simply, but effectively, bv having you play a single note in time with the beat. Remember, drills are called up as required and, 9 times out of 10, 1 agreed with the program's decision to send me back to practice some aspect of the lesson. During this process, your progress is tracked and charted, and your records can be perused in the Administration Office. If you have a problem with a term used in a lesson, there is ample assistance via hypertext .
Click on a highlighted word, and a detailed explanation is given.
Menus have Help Buttons that will further assist you. If only I had gotten this much attention in school!
There are two manuals. One addresses the keyboard, selecting patches (sounds), and MIDI technical information. It also has a glossary and presents a very entertaining history of the piano. Tile other is Amiga- specific and covers connections and using the software. There isalsoa quickstart card that realty tells vou everything you need to know, in case you have an aversion to manuals. Both manuals are clear, concise, and well- indexed.
Let me mention a few of the Amiga-specific details. The program requires at least 1MB of memory and Workbench
1. 2 or higher, and comes on three disks. I found trying to swap
disks, even with two drives, to be mi Idly annoying.
Fortunately, the program is not copy-protected in any way, and easily installed on a hard drive.
The program is very solid under Workbench 1.3 and 2.04, and completely multi-tasking. The games operate well, even while under the influence of my Mega-Midget Racer '030 accelerator. There are pop-up menus rather than pulldown menus and some of the re- quired mouse clicks and keystrokes could be improved slightly, but the bottom line is that the program is very intuitive and easy to use.
There is a special cable that connects to your serial port, and you a re cautioned not to try to use another serial cable in its place. If, however, you use your serial port for other purposes, say for a modem and a MIDI interface (as I do), then you can forego the cable and connect the keyboard's MIDI ports to your MIDI system.
The keyboard itself is an enigma to me. It is advertised as a professional keyboard, and it does indeed have 49 standard-size, velocity-sensitive keys. It is polyphonic (up to 16 notes at a time), and multi-timbrnl (8 instruments out of 128), and has 8 MIDI channels. It can be split to play different notes on the left and right halves (divided by middle C).
There are two speakers built in.
Then, in the back, there are MIDI IN and MIDI OUT jacks, but no MIDI THRU jack. There is a rinky-dink two pin jack for a foam rubber (!) Sustain pedal, leaving Two musical games: "Aliens", left and "Ducks", below, which aide in associating keyboard keys with certain notes.
Me no hope of using my professional Yamaha pedal. Furthermore, rather than using a professional 1 4 inch stereo headphone jack, the system usesa smaller jack for tire included "Walkman" type ear inserts. There are two RCA pin jacks to connect to an external sound system, but inserting the earphone plug is the only way to shut off the built-in speakers.
That being said, 1 must point out that, in the interest of keeping the system as economical as it is, the choice of putting the money in the keys themselves was the right one. The keys are solid, and have a true piano touch. The sound quality is about average for a keyboard in S300-400 price range without an entire teaching system included.
In future versions of the software, 1 would love to see a less volatile place marker for the lessons, so one could go back and forward in the course without running the risk of having to start a chapter over again because of your reviewing or previewing a iesson. It would be nice if the Jukebox in the Arcade would allow you to select a list of songs to play, rather than being allowed to make oniy one selection at a time.
I also wish the instruments in accompaniments were editable, perhaps in the Studio. 1 find some of the instru men tat ion grating and confusing when confronted by it in a "performance," especially when used in a syncopated rhythm. As it stands, the only recourse is to turn down the Orchestra Volume option in the Administration Office. While we're at it, a patch ed itor for the re-configuring the keyboard would makelifea lot easier.
All of this nit-picking belies the essential question, "Can this system teach someone to play the piano?" The answer is an unqualified "Yes!" The Amiga made it possible for me to share the music that was in my head through extensive editing with a MIDI sequencer. While 1 am notyet a level at which I can play my own compositions live on the piano, the Miracle has made it possible for me to play one of Mozart's compo- sitions. (Hey, "Twinkle, Twinkle, Little Star" is too Mozart!) 1 enjoyed playing it, basic as it may be, and 1 am realizing a dream I have had since 1 was eight and my
parents told me we couldn't afford a piano and lessons.
I ency the six-year-old who sat in front of the Amiga, at my dealer, for one-and-a-half hours and was playing two-handed piano when he left. He had never touched a piano before, but his dad discovered what Santa Claus was going to bring the boy. My dealer's ten-vear-old niece had had six- months of piano lessons be- forethearrival of theMiracle. Now she supplements her regular lessons with practice on a system that catches her errors as they happen, and improves her playing.
THE GR UPEVINE GROUP, INC. North America's Largest Supplier of Amiga Custom Chips.
Can the Miracle teach someone to be a great pianist? I doubt it.
Though this system does exactly what it says it will do, I believe that some human input is necessary for instruction in the finer points of playing an instrument. But, like the poker-playing dog, it's not so much that he plays poker well, but that he plays poker at all. Then again, I'm only on Chapter Four, out of forty, and I'm told the company is coming out with an advanced course. Hmmmm.

Fans of Scene Ggnrra for will be happy to know that the program is back in much more than an update, but a completely new program. Scenery Animator from Natural Graphics brings together smooth 3-D landscape animation through keyframe editing. In addition to standard IFF, there is hi- coior support which includes IFF 24-bit frame creation for use with such devices as the Firecracker 24 board and the Video Toaster. There is also an option to render complete hi-res DCTV images and animatations from within thepro- gram. These and many other variables options combine to create a feature
packed 3-D scene animator easy enough for beginners yet powerful enough for broadcast output.
The main interface screen has several rows of buttons down the left side and below, with a rough graphic representation of your current location on the right. You can scroll around using this preview screen by simply clicking inside of the preview graphic anywhere you want to go. If you want to zoom in, just draw a box within the preview image and in a second your camera has moved. More precise controls arc available just below, with options for moving on the X, Y, and Z axis.You can rotate your camera or se: it to "Low" which automatically keeps it just above the ground level sur
face during animated fly-bys. A zoom bar is used for gradual as well as dramatic zooms. The land button allows setting the level for snow, rock, and vegetation. A toggle swi tch turns soil on a nd of f. Soil appears in areas which have no snow, rock, or vegetation. Ver- tical exaggeration enables "stretching'' the land vertically or flattening it out. Very dramatic effects can be created using various settings.
NATURAL GRAPHIC1 S Scenery Animator World in Motion by Frank McMahon Scenery Animator creates and animates beautiful landscapes.
Clouds can be generated by random seed. They also can be adjusted via altitude and density.
This enables setting the clouds lower than the camera for that "above the clouds" look. Clouds canalsobeanimatedvia keyframe animation. You can have a static shot of a mountainside while clouds move across the horizon or animate the landscape in addition to the clouds. Light can be set to any direction and any angle 'ather than the front, back, side, etc. of Scene Generator. Water can be added via oceans or lakes. Lakes are created just by clicking the mouse in low lying areas. Cceans levels are changed bv altering the water level. You can always recede the ocean, but you cannot remove a
lake you have formed without reloading the original landscape. Waves which reflect the sunlight can be toggled on or off.
Scenery Animator's main interface screen presents you with a graphic representation of your current location. The control panel allows you to move around the area selected.
A Dash of Color Colors for the sky, water, and land in standard Amiga resolutions can be altered after you r rendering takes place via a simple 32- coior palette requester. A separate screen holds the palette selections for rendering to a frame buffer.
Options to change the colors of the sky, snow', rock, vegetation, water, and soil are available with 16 million colors to choose from.
Frame buffer dimensions can be typed in manually. Amiga or DCTV dimensions can be set by clicking on standard resolution buttons. DCTV users can select all standard DCTV resolutions and also set the depth to three or four (eight control colors or 16 control colors).
Other options include the ability to "Clip" out sections of your map which will not be rendered for added memory savings.
Landscapes can also be appended allowing huge fly-by animations crossing great amounts of terrain.
While the included landscapes cannot be appended, Natural Graphics has many data disks available (eight at last count) which can be joined. These disks are low cost and high on variety, featuring everything from Yosemite to Lake Tahoe to Mount St. Helens. Another alternative is to use the random seed fractal generator built in to Scenery Animator for creating new' regions. This gives you thousands of varying landscapes, 65,535 to be exact, which can be altered and saved to disk. Creating your own terrain has never been easier!
Flying Above the Clouds Animation couldn't be simpler. You can create frames either on the main interface screen or on the map screen, which shows a scrollable overhead view of the entire terrain. Options, including camera direction, altitude, lens focal length, pitch, and numerical coordinate locations, are all available using numerical inputs or simple mouse movements. In fact you could get by using the mouse for every part of this program if you don't like typing in requesters. Mouse commands for every option make creating in this program very quick and very easy.

Conclusions Scenery Animator makes an excellent entry-level introduction to landscape creation animation because it's mouse-driven format is so easy. But don't be fooled by ease of use; this powerful program creates stunning imagery. There is a detail button that toggles off and on for even greater added detail. Scenery Animator uses Digital Elevation Model data sampled every 30 meters. With detail "on," the resolution is enhanced up to 0.1 meters so you won't see any polygons. Rendering modes include standard IFF, 1FF24, DCTV, and PCX, with animation modes featuring IFF ANIM5 and DCTV
ANIM5. I've rendered several DCTV animations and the quality is excellent.
Because of the hi-res frames of DCTV, a depth of th ree and a reso- lutionof640 x 200 with or without overscan is recommended even with a 68030. Color plays a big part in this program, and colors can be altered to create green alien planets, white moons, and just about anv other surface imaginable.
The first release of Scenery Animator required the use of an accelerator, 6S020,030, or 040 and a math coprocessor chip. The program would noi even boot up if it did not sense the presence of the accelerator. True, a program like £][§][ The map screen shows a scrollable overhead view of the entire scene.
An abundance of options allow fine- tuning of views and movements.
Mouse East 7380 North 9180 Elev 1646 commands for every option make movement very easy.
This would probably move slow on a stock Amiga, but that hasn't stopped many users from working with other 3-D programs on unaccelerated machines. Fortunately, the latest release, vl.01, which has been available for some time now, does not require an accelerator. Both the 68000 and accelerated versions are included on the program disk. Die only not- so-hot point is that, like Scene Generator and similar programs, the burn-out point comes pretty quick. Scenery Animator creates and animates beautiful landscapes, but that's all it does. The random generator and the flow of data disks
will keep hard-core fractal fans busy, but others may get bored a f ter a urh i !c. The sa vlng grace is its low' price that keeps it from being a major commitment.
Oilier than that, if you are looking for a powerful, easy-to- use scenery program featuring 24- liit output and DCTV animations along with a wealth of features, then Scenery Animator is an excellent choice.

REAL-3D Pro 1,4 by R. Shawms Mortier HI HHI Touted as the
"best Amiga 3D software in Europe", Activa I nterra tiona l's
Real-3D has landed on these North American shores.
Though the comparative thinness of the manual that accompanies it might hint that the software i nsid e is equally light, just the opposite is true. This is professional 3D software that is as heavy as any of its more well known American competitors, and it also does true ray- tracing, meaning that 3D objects can reflect back the view of their environments and cast shadows upon other objects while in motion. Some of the tools that it contains can be found nowhere else in the Amigaverse. Juha and Vesn Meskanen, the two Finnish math- ematician programmingbrothers who live in the woods
and whose brainchild Real-3D is, spent over four years in bringing this product into reality, and their efforts show in its design. It is also apparent that they were motivated by the clone of a ny other Am iga software, but the three-view screen design and some other attributes echo an obvious honoring of the earlier Amiga product.
Look of Sculpt-3D early on, so much so that Sculpt-3D (from Bytc-bv- By te) owners fa miliar with the way that Sculpt works will have little trouble learning to use tins new software. To be sure, this is not a Ray tracing time is always stretched when there are more complicated scenes to render, and 1 would strongly suggest that the Amiga artist animator that decides to purchase and use ReaI-3D (or any other Amiga 3D 4D product) be in possession of an accel- Figure 1: Your objects can be sculptured, wrapped with an infinite array of textures, and ray traced with cast shadowing in Real 3D
1. 4. erator board and math- coprocessor, preferably a 68030 or
68040 and a 68882 math coprocessor. The Real-3D disk comes
with a vanilla program that will run on a standard 68000 ma
chine as well as a turbo version for accelerator owners. But
having tested them both, I found that the vanilla version ran
four to seven times slower.
The whole premise of Real- 30 is that the user will want to create objects that have observable properties that are an almost exact match for real world materials. In addition to and because of that, you can also create some fantasy objects that could never be "constructed" in tbe non-digital environment, and make them move at the same time. You can even model lens-like objects which bend the objects that they are placed in front of like true lenses do. Moving an almost transparent wine glass in front of another collection of 3D objects can create some startling looks. Real-3D has a
collection of four modeling "primitives" thatcanalsobeadded to your 3D compositions to further enhance the believability of a scene. They are a ball, cylinder, cone, and hyperboloid, and because they are called up as true 3D primitives, they have no apparent polygonal edges or corners, no matter how large you make them.
This is great for users wishing to wrap these primitives with textures, or to assign metallic properties to their surfaces. Images can be saved as HAM files, higher resolution grayscale files, or 24bit files (IFF ILBM and Targa are supported, and REAL-3D can display Targa pictures on your Amiga screen by converting them into HAM mode). An animation conversion utility also converts Sculpt files to the Real-3D format.
Boolean Utopia Boolean operations are those in which whole objects can be set to either "yes" (visible) or "no" (invisible) states. Renl-3D uses exquisite Boolean math to allow you to use one object as a "drill" or "chisel" to sculpt another. Allow me to give an example. Suppose you have a sphere and a cylinder.
You can pierce the sphere with the cylinder, tag the cylinder as an invisiblepartner,and...VoiIa!...you have a sphere with a cylindrical hole through it. But Real-3D's Boolean operations are even more complicated than that. Our cylinder could be shiny and or of a different color than the sphere. The hole that is drilled in the sphere could take on the very surface attributes as the "drill", also becoming shiny and differently colorized, Boolean operations are called "logical operations" because they take effect in a very specific fashion, and are basically digital (yes no) in quality.
The standard Boolean operations are performed on 3D images in Real-3D, and consist of AND (where you get only the "hole" produced by the intersection of objects), AN D NOT (where you get one object minus the intersection and not the other), LOR (where you get both objects but not the surfaces implicated by the intersection), and DIVIDE (dividing the object into to parts, consisting of the acted upon object minus the intersection, and the shape of the intersection itself). The default Boolean operation OR creates either one object or the other with the intersection computed in. See
Figure 1 for an example of the creative possibilities of a Boolean digital sculpture. Boolean logiccan be used to create very complex shapes, like lenses.
Reai-3Dcontains 24 different ways to bend and twist free-form objects, so that creating more organic looking shapes is made simple. Listing them all would take too much space, but here are a few that I found intriguing in my 3D work: RADIAL modes redirects the bend function away from the targeted bending axis; EXPLODE breaks an object apart into its primitive pieces; SPIRAL creates a user definable spiral surface; four BEND operations (End Point, Global, Local, and Linear) bend an object with different results. There are many more options available.
REAL also allows the Amiga user the capacity to "explode" a lathed sculpture into separate elements, a needed operation if you are involved with producing mechanical parts for industrial purposes.
Great Looking Texture Mapping Capabiiities Not only can you wrap anv IFF image (including 24bit ones), digitized or painted, around a 3D surface in REAL-3D,but your textures can also be mapped to surfaces in four different projections: Parallel, Cylindrical, Spherical, and Spiral. Each is appreciable in different situations. A soda can, for instance, would have its label wrapped as a cylindrical projection, while a beach ball would look bestwith the spherical alternative.
Flat surfaces would use the parallel mode, while spiral projections offer novel options. See Figure 3 for some comparisons. By selecting "NO O-COL", thecolorO in the palette of the texture to be wrapped is dropped, allowing the surface of the 3D object to shine through the texture. Another novel approach is to use a texture to cut: a surface utilizing a special "CLIP" tool, in which a hollow object's surface not painted by the texture is removed. Very interesting cutaway and mesh surfaces can be created in this manner, By combining UNSHADED and SMOOTH opera tors with textures, 3D
objects can appear as if made from fog and other substances.
Real Tools Like all other Amiga 3D software, REAL-3D has all of the standard extrusion and lathing capabilities for creating simple and complex 3D surfaces, as well as a lathing option that automatically sepa rates pa rts of the la thed figure into individual pieces (that can be "exploded " later in an animation).
In addition, however, it possesses some tools that no other 3D program, Amiga or otherwise, boasts (at least in this style). One of these is the TUBE tool, allowing you to draw 3D tubular shapes whose volumes are made from spherical, cylindrical, and polygonal primitives. The FENCE tool is useful in designing polygonal surfaces, and generates a chain of zero depth rectangles. You can imagine the outcome of this tool if you can visualize extruding a meandering line. The example of its use in the manual is a computer designed piece of lawn furniture. The POLYHEDRON tool allows the creation
of surfaces that are made from polygons.
By far the most unique sculpting tool in Real-3D is the PIXEL tool (which no one else has even thought of!). See Figure 4 for a visual example of its results. In general, the PIXEL tool allows you to replace each pixel in a 2D brush with a 3D object! This is a great alternative for Amiga logo designers who are tired of the same old look. First, you create a 2D text or graphic in a paint program (like EA's Dpaint IV), save it, and import it into REAL-3D. Colors are taken into consideration, so that you could use a niceColorFont in this process. In REAL-3D, the 2D surface is examined, and
you can determine what 3D shape (including extruded shapes) are used to replace the pixels. The finished piece looks like a surface made from hooked rugs or marquee lights. There is also a PixeITool2 that can shape landscape areas from IFF lumn chroma data.
Rendering The only other Amiga 3D ray- tracing software that matches the quality of REAL-3D’s HAM rendering is impulse's Imagine. The developers of RE AL-3D seemingly have taken great pains to respect this traditional Amiga rendering mode with smoothing algorithms and other trade secrets. The way REAL-3 D targets colors to spec i fic objects is unique to the product. A color requestercan be accessed that shows 2,4, H, or 16 color registers.
Below are RGB sliders that can adjust any of the colors. New color parameters are then attached to selected objects from this limited palette. 24bit renderings arc saved directly to a file, so it's best to preview them first in lower resolutions and or less complex (e.g., non-shadowed) modes to make sure the compositions are what you want. REAL-3D has some wonderful "BumpMapping" routines and capabilities that make even the animation of watery surfaces possible. Even if you choose no shadowing or ray tracing, REAL 3D can produce images that may be just right for the flatter more cartoony
animation look you desire.

Wind Rewind gadgets allow you to move easily to any frame. Aim points determine where the camera is looking in the scene, and wireframe mode allows the user to preview the motions set. It is always best to render frames to RAM (if you have a good chunk of it left) or to a hard disk, as animations are seldom of the size that will
fiton a floppy. REAL-3Dadds a numeric indicator to all of the frames saved (01, 02, 03,..etc.). "Orbits" can be tied to an object in any view, and the objects set in orbital motion alonga created path.
Objects can also rotate as they move on a path. Curved orbits can move objects in several planes at once. The direction of objects on a path can be specified.
"Exposing" an object means that its motion has been set in an animation. Objects not exposed are motionless, and acting on them (targeting them in middle frames for animation) without following this up with "exposing" the movements will cause the animation to disregard their movements. Ex- posing De-exposing, then, actually is the difference between beginners and expert mod e i n R E AL- 3D. If an object has been exposed, it is indicated in an associated instruction window by an "x" in its name. By exposing objects in separated frames, movements are confined to segmented regions of
an animation, it's rather complex to understand from a description of the process, but becomes more intuitive the more you work with the process itself. What is important is that it can lead to some interesting ways that objects move during an animation. Animations can be joined (giued end to end) or concatenated (glued togetherfrom a targeted frame on). There is also a way to have the computer generate the "in betweens" from one movement to another over a series of frames, a task that Amiga animators expect in any serious aniEDITOR | i.H K I I..

Observer position and aim point can also be fully animated, giving your REAL-3D Amiga animations a variety of possibilities for any one scene, desirable in the storyboarding process, and sometimes these alternatives can actually save memory when writing the animation to a file.
REAL-3Dhas some attributes tha t make me think it was designed for more then logo videography, and certainly for more then just innocent Amiga fun (though it is excellent for both of these goals as well). It has a function that allows you to calculate the "production costs" of an object, making it a desirable tool for Amiga Computer A ided Man ufact uring (C AM). Tire processis simple and fully detailed in the manual.
Other Observations REAL-3D's Delta format is not the same as an ANIM5 compression format, and this should he altered as soon as possible if this software expects a share of the American Amiga market. Amiga animators do no want to engage in unnecessary file conversions routines in order to maximize their efforts. They want everything at hand that will aid in the creative process. For this reason too, it would be wise for the developers to consider addressing the DCTV mode (Digital Creations proprietary file format) directly, instead of only allowing 24bit file saves that can later be
imported and translated by the DCTV unit. The DCTV unit is fast becoming an ..RENDERER II r Mrerst iSHADOMLESS i NOWAU ] JMItHJU-V- t | CvtHtWVt j onxrvrAtr | Dir*!* r~«tAVFHrH ¦ r« Amiga standard as a medium end animation system, and judging by their sale of products at the recent European shows, is spreading its Amiga fame outside of U.S. environs. The REAL-3D format is not an Amiga standard and has little hopes of becoming one, and it takes too long and is unnecessary to reprocess animation frames. Although REAL-3D does convert Sculpt 3D files to the REAL format, it would be better
if it addressed Imagine, Videoscape, and or Toaster-Lightwave files in the same manner.
Conclusions The easiest way to get the rendering view you want is to use the Wireframe screen's interactive tools. The Editor tools, as far as selecting the correct viewing angle and aim point, are too complicated.
Very complex drawings take a lot of time to redraw to the screen.
This is true even on a 68030 machine. I would like to see the design of the Editor's quick tools approach a more standardized look in the future. It would also be welcome if this software inported more other formats directly. The HAM Tenderer is excellent, and it's easy to save to24bit files. All in all, REAL-3D is a wonderful addition to the Amiga's expanding 3D 4D toolkit, and it probably will spark other Amiga 3D developers to consider new areas of possibility. The development of Amiga art and animation is driven by healthy Competition, and for this reason alone, RE AL-3D1,4
is a most welcome player on the Amiga scene, I Figure 5: The Real 3D screens: Editor, Wireframe, and Renderer.
Would especially recommend this software to designers and manufacturers of mechanical items and processes, as it has the capability to turn the draughtsman's vision into colorful and believable 3D REALity (including an option to actually "price" parts in the design process).

The MegAChip 2000 500 is a chip RAM expansion board that plugs into the Agnus socket on an Amiga 500 or 2000. By utilizing address space reserved for the second megabyte of memory, the board enables up to 2MB chip RAM to be installed on the motherboard. Because the board plugs into the Agnus socket, the installation of the MegAChip board is a bit involved, but it is not beyond the ability of the average Amiga user. However, if you have never taken the cover off your Amiga, the installation is best left to your authorized Amiga dealer.
A few basic hand tools, as well as a couple of specialized tools, are required for the installation. A Phillips screw driver.a flat blade screw driver, a soldering iron (A500 only), a T10 Torx screw driver (A500 only), a wrist band grounding strap, and a PLCC chip extractor are needed to perform a trouble-free installation of the MegAChip board.
The MegAChip 2000 500 chip RAM expansion board for the Amiga 500 or 2000.
The MegAChip board works only with the 2MB Agnus chip and will not operate with the older 1 MB or 512K versions. In add ition to the Agnus requirements, certain versions of the motherboard may not be compatible with the MegAChip board, if the motherboard is revision 6.0 or 6.1, equipped with a small tower assembly to the left of the RAM array, DKB should be contacted. I telephoned them to find out more and spoke to Bob Tingley. He told me that if you have one of the motherboards in question, DKB would exchange your standard MegAChip board for a high-rise version for the cost of shipping
The first step in the installation is determining the current memory configuration of the computer. This is done using the 'avail' command. Typing the 'avail' command in a shell window will produce a display of the current status of the memory in thesystem. The Maximum column shows the total amount of each type of memory (chip or fast) installed in the system, if the Maximum column is six digits wide then thesystem has a 512K Agnus; if the Maximum column is seven digits wide then the system has a 1MB Agnus. This information is used later in the installation.
DKB SOFTWARE'S MegAChip 2000 500 by . V. Botelho The next step is to power down and disassemble the computer. First, the AC power cord is unplugged. Next, ail tire peripherals (mouse, keyboard, external drives, etc.) are unplugged. The case can now be removed. For an Amiga2000 this requires, removal of the four side screws (two on each side) and the one screw in the back. Then the case can be siid forward and removed. For the Amiga 500, the unit must be turned upside down and the six Torx screws must be removed. After doing this, separate the top and bottom covers by applying slight
pressure to the sides of the case.
This will allow the two sections, which are snapped together, to pop apart.
Once the case has been removed, the motherboard must be exposed. On the Amiga 2000, this is accomplished by removing the power supply anddiskdrives. The power supplv and disk drives are mounted on a metal plate which is secured to the chassis by screws in the front, back, and sides. Before the assembly can be removed, the main powersupply connectorand the floppy drive controller cable must be unplugged at the motherboard. In addition, any power cables going to peripherals, such as hard drives, must be disconnected.
Gaining access to the motherboard in the Amiga 500 requires removal of keyboard and RF shieid.The keyboard is removed by unplugging the keyboard cable at the motherboard and lifting the keyboard out of the case. The RF shield is secured in place by fourTorx screws and four small metal tabs. The screws must be removed and the metal tabs straightened to allow the shield to be lifted out.
Now that the motherboard is exposed, the Agnus chip can be located and removed. The Agnus chip is to the right of the Motorola 68000 CPU chip and is the only square PLCC component on the motherboard. Removal of the chip requires a special PLCC chip extraction tool which can be purchased from DKB Software for $ 15.95 plus postage and handling.
The tool looks somewhat like a pairof spring action tweezers. The tips of the extractor are hooked under the corners of the chip and the chip is pulled straight out of the socket with a slight side-to- side motion. A word of caution: the chip should not be pried out with a screwdriver as the socket and or motherboard mav be damaged. Once the chip is extracted, it can be set aside since a 2MB Agnus is needed for the MegAChip board. According to DKB, most MegAChip boards are shipped with a 2MB Agnus chip already installed.
Once the Agnus chip is removed, the next step is to make configuration changes on the motherboard utilizing information obtained from the 'avail' command. For the Amiga 500 motherboard, with 512K, the configuration changes involvecutting traces and soldering pads. First, jumper JP2 must be identified. It is located next to the lower left corner of the Kickstart ROM. Tire trace between the middle and lower pads are cut and then the upper and middle pad are soldered together. The next trace cut to be performed is done two different ways, depending on the revision level of the
motherboard. If the level is 6A or higher, then there is jumper JP7A that must be identified. It is located to the right of the Agnus trip and is similar to JP2.
The only thing that needs to be down on JP7A, is the trace between middle and lower pads needs to be cut. I f the motherboa rd is revision level 5 or lower, then there is no jumper JP7A. Instead, the trace that runs from a solder pad across from the eighth pin set of the CNX connector, and then along the connector, must be cut.
All the cuts must be done with extreme care to insure no other traces are cut inadvertently. Now the Amiga 500,5] 2K motherboard is ready for the installation of the MegAChip board. If the Amiga 500 is equipped with I MB of chip memory, no reconfiguration is necessary.
The reconfiguration of the Amiga 2000,512K motherboard is much simpler than that of the Amiga 500. For revision 6 or higher motherboards, two jumpers need to be changed. Jumper J10I, located to the right of the main power supply connector, must be changed from the connection of the middle pin and the lower pin, to connecting the middle pin and the upper pin. Next, the jumper block shorting the two pins on jumper J500 should be removed.
The Cl A RY chip. For revision 4.X or lower motherboards, jumper J101 is changed in the same manner as described above, but jumper J500 requires a trace cut. Once again, extreme care must be ta ken not to inad vertently cu t any other t races, I-‘i nally, the Meg Achip board can now be installed. There is a notch on the Agnus socket and on the Agnus chip on the MegAChip board. The two notches are aligned and the board is pressed firmly in the socket. Next, there is a jumper wi re attached to the board that has a special clip on the end. The clip must be connected to pin 56 of the CARY chip or
pin 48 of the 68000 chip. Now that the board is in place, the computer can be reassembled simply by reversing the steps which were described before.
I performed the actual installation and testi ng of the MegAChip board on an Amiga 2000 configured with a revision 6.2 motherboard, two floppy drives, a 1MB Agnus, and 2MB of Fast RAM. The installation proceeded as described above with one exception. When I had finished installing the board,! Thought it best to make sure my Amiga still booted. I put a couple of screws in the disk drive power supply bracket and reconnected the main power supply and disk drive cables. I then plugged in the keyboard, mouse,monitor, and power cord. I doubled checked all my connections and powered up the
beast. Nothing, no disk-in-hand display, no error, "no nothin'." 1 powered down and tried disconnecting and reconnecting everything. Still nothing, Finally, 1 disconnected and disassembled everything to allow access to the motherboard. 1 removed and reseated theMegAChipboard and repeated the partial reassembly procedure. This time the system booted and loaded fine, i powered down and booted the system several times for my own peacee of mind, and there were no further problems. Apparently, the board did not sea t properly the first time.
After completing the reassembly process,! Rebooted the system and then ran the 'avail' command. It now shows that my Amiga 2000 has 2MB of chip RAM.
Three packages were selected for software compa tibility testi ng; ProWrite, Deluxe Paint III and Maxiplan Phis. ProWrite was used to compose this article and the fact I hat it was com pleted is testament to the MegAChip hoard's compatibility'. I began the article before the MegAChip card was installed and completed it with the MegAChip board in place. Word processing packages don't typically require much memory, but since ProWrite is a popular package, I thought it would be a good first-level test.

Jumper J500 is located just above Next, I began experimenting with DoluxePaint III. Before I started, 1 set my' memory configuration to "No Fast Mem." Then I fired up Dpaint and began painting a picture. All was fine, so I began to tax the system a little bit more by going back to the Workbench and firing up another copy of Dpaint. I continued to drop back to the Workbench and fire up another copy of Dpaint until i had five copies running and about 50K of chip RAM free. I then began moving between the different sessions of Dpaint, making a few changes on each drawingas I went along.
Everything worked perfectly, no gurus, no low-chip memory warnings. I went back to eachsessions, layer by layer,saved my drawing, quit and went on to the next one until all sessions were closed. Once again everything worked perfectly no gurus, no low chip memory warnings.
Next I tested Maxiplan.Once again i set my memory configuration to "No Fast Mem" and started up the application. Maxiplan started up without a problem, and I began creating a worksheet. I continued to copy and add rows and columns until 1 had created a 75 row bv 20 column worksheet. I saved it, read it back in, modified cells, and then saved it again. No problems. The tests were not meant tobeexhaustivebut only to serve as a confirmation of the board's proper operation. There was no detectable difference in the way the system or software packages performed before and after the MegAChip card
The MegAChip board can be installed by the average Amiga user who has a little bit of skill and a little bit of patience. The Installation and User’s Guide supplied with the board is well written and easy to follow. The Guide not only contains detailed installation procedures but it is also well illustrated. The MegAChip card, once installed, performs as advertised and delivers a full 2MB of chip RAM. The price is a bit steep at $ 300 for 2MB of RAM; however, it is the only way to install the 2MB Agnus chip in an Amiga 2000 or

A quality PostScript laser printer for your Amiga.
There are times when I have to sit back and laugh at my remarkably cavalier attitude about spending a significant amount of money for something. I have frequently found that intuition and word-of-mouth are stronger and more reliable incentives than a careful analysis of specifications, however. I purchased an Epson EPL 7500 PostScript laser printer sight unseen, based primarily upon a feeling. I reviewed another product of thei rs, the ES-300C fla t- bed scanner, that impressed me so much with its thoughtful design and high quality workmanship, that I couldn't shake the feeling that I
would be best off with an Epson, when it came time to buy a good PostScript laser printer, i looked at a few printers, some of which had "better" specifications as to print speed, etc., but 1 ended up following my intuition, much to my joy. Only one person I know had actually seen this printer, and he said it was very fast, thanks to its RISC (Reduced Instruction Set Computing) processor, but I had never seen one demonstrated before I special ordered it at a local dealer. You can get this printer for under S2000 if you shop around, but it is anything but a "bargain printer." Quality is
clearly a function of its list price of S3299.
What to Look for in a Laser Printer E P S O N 'S EPL 7500 PostScript Laser Printer by Merrill Callaway There arc five main criteria to choosing a laser printer. The first one is the software to run the printer. Every laser printer depends upon some sort of software to control the type faces and fonts as there is no hardware as such to impact the page and print the characters. The characters are written with laser light on a selenium drum which is photoelectric. The electric charge on tire drum changes as it is exposed to light. Thedrum then p icks up toner d ust by means of the sta tic
electric charge on it, and rolls the printed characters onto the paper as it passes underneath. The final step is a fuser which sets the toner, a plasticized carbon powder, with heat. The actual printing of the paper is a process similar to that used in a photo copier, but the image generation on the drum itself is not. There are at the moment two kinds of software to make the laser write the characters on the selenium drum; Hewlett Packard LaserJet (II or
111) ; and PostScript software. Of the two, PostScript is by far
the better and more powerful, butal- mostevery laser
PostScriptprinter offers an HP LaserJet emulation mode as a
standard feature. It is therefore better to choose a true
PostScript printer that emulates HP than an HP printer that
emulates PostScript, because once you use PostScript,
you'll never go back to LaserJet unless vou have to.
Also, upgrading an HP LaserJet printer to do PostScriptendsupas expensive as buying a PostScript printer in the first place. The onlv reason I ever use LaserJet mode is toprint through Preferences when I am forced to. Commodore has not seen fit to include a PostScript driver in Preferences, an odd oversight given their zeal to be taken seriously as a professional platform. In my initial research, I discovered PostScript's superiority and actually waited overa year for the prices to come d own befo re I made my purchase, rather than buying an HP LaserJet, good as they are. Unless you print
just Straight text, you will inevitably upgrade your HP LaserJet with a PostScript cartridge; and since in the end you will spend more than if you had bought a PostScript printer in the first place (and your printing will be substantially slower), why bother? That is why 1 waited, and I'm not sorry I did.
The Minolta Print Engine The second and third criteria for choosing a laser printer are speed and the type of print engine. Every laser will outperform your old dot-matrix printer, but speed will become an issue as, just as in "The Princess and the Pea," you get used to your new convenience. The speed of a printer is determined mostly by its proces- sor, and in part by its "print engine." Despite what most people think, there are only a few pro- cessorsand printenginesout there, and many manufacturers who install them in their printers, Avoid the proprietary and the of f-b ra nds of
print engines. The most universal, thanks to HP, is the Canon engine, which is used in al 1 LaserJet printers. It is an integrated package that contains toner, d rum and ail. You pull one out and install another and you have essentially a new printer. This is probably the most fool proof way to doit,but as they say a fool and his money are soon parted; alas, this is not the most economical way. The drum, if you take reasonable care of it, will last for thousands of pages more than the toner will. There is a viable industry now to rebuild cartridges, by recharging the toner in them, and
cleaning their drums.
A major new contender for the "baddest print engine" crown is Minolta, makers of the engine for the Epson EPL 7500. It is rated at six pages per minute (ppm). It, too, is a self-contained imaging cartridge with a drum and toner sealed inside. It is rated at 6000 pages of full text and the price is nearly the same as the Canon, around 8100. Some laser manufacturers have elected to expect users to exercise reasonable care not lo get peanut butter on the drum and to load their own loose toner. This is definitely more economical, but messy, as demos at stores proved to me. The output was dirty
and spotty in every case where a machine used loose toner and a separate drum. Also light ruins dm ms. Every timeyou open the hood on a machine with a separate drum, you run a risk.
Since those floor models had been opened a lot and misused, their output was degraded unaccept- ably. I n the final analysis, economy is not the main criterion. Other things like maintainability and reliability are much more important. Logistics keeping your system alive and well under less- than-ideal field conditions is a subject that few salesmen will broach in the frenzy of the sale.
The Speedy RISC Processor Speaking of frenzy, we come to processors and their speed. Did you know that many of the PostScript lasers use the Motorola 68050 chip just like in the A3000 computer? The Epson is an exception, but a good one. It uses a RISC processor chip made by Weitek, the small company that recently won a suit filed against them by Intel, alleging that they had violated patent rights. Weitek is one of those giant-killer companies that I vvish Commodore would emulate. They personify the free enterprise, entrepreneurial style of the early days of computing.
The Weitek is an Intel RISC processor done tha t costs a fraction of the original. The reduced instrucThanks to its RISC processor, the Epson has quite on acceptable speed.
Tion set means speed. The latest trend in microchip design is to reduce the complexity and increase the speed, much analogous to a limited access freeway. One of the specifications of a laser printer is ppm, but they don't always tell you that this applies to text and not graphics. If you print an entire page of graphics, the throughput will slow down dramatically. The supreme advantage of a RISC chip is that it almost doesn't care whether its graphics or not. My Epson will do six ppm, and another brand may claim "11 ppm,” but my Epson will do almost 6 ppm with full-page graphics and the
other one will slow down to minutes per page. It's sort of like the fact that a "slow" Amiga beats a "fast" IBM because of multitasking. After the EPL 7500 warms up to the ready state (70 secs), I do not have to wait a minute for the first page to print; it prints almost immediately, The processing times on complex PostScript graphics programs seem to me very impressive. 1 ran a PostScript recursion program that makes a fractal design. It has to compute the recursions ten deep,and do this four times: each time after rotating the coordinate system 90 degrees.
That's at least 4096 complicated calculations, not counting rotations, line width, and scaling calculations. The page prints only a little slower than a full page of text. 1 never get the feeling that my printer is slow, and that's the important thing.
Small Size and Weight 1 don't have a lot of room in my office. The size of the machine made a difference to me, and perhaps it will to you, too. The Epson EPL 7500 won me over because of its small size and weight, which [ checked before I bought it. It easily fits on the small printer table that used to house my very small Star NX-1000 dot-matrix printer, i had expected to need to buy a bigger table, and this was a welcome bonus. The actual dimensions of the EPL 7500 are a mere 19 inches wide by 14 inches deep, but you will need some 4 inches of clearance in back for cables. The
footprint of the legs is even smaller.
The overall height is a little over 7 inches, but the printer lid needs 17 inches of overall height for clearance. You will need an additional 10 i nches in front for the 250 sheet paper tray, 13 inches if you use the legal paper extension. Since I have mine on a stand with rollers, 1 roll it out lo service the printer. There is an optional face up paper output that attaches to the back and takes up 9 inches. In the basic con- figuration, the printer will fit into a cubic space (including Epson's recommended access room) of 27 inches wide, by 32 inches deep, by 17 inches high. With the
face up output tray recommended for transparencies and envelopes and stiff print stock toavoid bending vou must add 12 inches to the depth dimension. The weight is a scant 40 pounds including tray and image cartridge. If you' re used to a dot matrix printer that you can tuckunderyourarm, thismay seem bulky and heavy, but just wait until you compare these specs with the laser behemoths down at the computer store. For instance a rival PostScript printer weighs in at 75 pounds and is half again as big.
Built-in Fonts The fifth criterion for judging a printer is by its fonts. The EPL 7500 has the full standard 35 PostScript fonts built in. Since these are the standard PostScript fonts, if you have a program that uses standard PostScript fonts in its driver, then the two sets will match. For instance, I have Page- Streain, and I ordered the fonts plus pack, which contains screen fonts and font metrics for exactly the set of built in fonls on the EPL 7500 printer. Industry standardization is an important advantage of going with a true PostScript printer instead of a "bargain" printer. Don't
be misled by the claims of printer manufacturers that 17 fonts is enough. You will not realize the implications of the lack of fonts until it's too late.
Downloaded fonts make everything slow down as you need to load them and you'll soon find out how much that extra needed memory and those font cartridges and disks cost. You could have bought an Epson by then.

RAM, upgradable to 6MB. Epson didn't skimp on HP LaserJet emulation, either. In HP mode the printer has access to three built-in bit mapped fonts resident in the printer's ROM: Times Roman 10 pt., Helvetica 10 pt., and Courier 12 pt. Fonts, In addition, there are two slots, A and B, on the front of the printer that accept Hpcompat- ible font cartridges. Back in PostScript, the resident fontsare outline fonts that may be filled any way you choose and scaled any way you want, smaller, larger, tall and skinny, shortand fat, in an infinite variety of choices, and of course, you have full
graphic capabilities as well.
Per tray attaches. Then you install the cleaning pad from theimaging engine package, and finally the engine itself. You remove a tape protecting the mouth of the toner slot, and shake the cartridge in the prescribed way and finally slide it home on its rails. Everything is well illustrated and explained both I couldn't shake the feeling that I would be best off with an Epson when it came time to buy a PostScript laser printer.
Set Up Setting up the printer the first time takes only a few minutes. The lid has a large latch on the bottom of the front edge to allow it to swing up to either 45 degrees or 70 degrees, depending on what you need to do. At the maximum open position, first you remove a protective travei plate which protects the paper entry slot where the pain the manual and in the imaging engine package instructions. The lower position of the lid is there to prevent excess light from affecting the imaging cartridge should you need to clear a paperjam. Since the imaging cartridge is modular and simply
slides into its position with a minimum of fuss, there is not much else to do but attach the paper tray and connect the power cord and the cable (either parallel or serial).
Controls and Interface The control panel allows you to select and configure the interface and select the software mode of the printer. The keys are flush mounted and sealed under plastic but they have good tactile feedback. You can abort a print quite easily by pressing the on-line button and then the reset button.
There is an LCDdisplay to tell you what is going on; which modeyou are in; and the status of the print: waiting, processing or printing.
There are also several LEDs to indicate other status information, as well as a beeper, which mav be turned off, to give audible feedback. The commands are implemented by means of a branching menu exactly analogous to your Amiga directory trees. There are four arrow buttons like the cursor keys on your keyboard to go left, right, up, and down, which are used to navigate the menu trees. If you come to the end of a branch in the menu tree, pressing the right arrow again selects that option.
Pressing a left arrow pops you up to the parent of that branch; and the up and down arrows take you to other options at the level you are on. In the offline mode, you have access to two Select Tvpe buttons which call up two different menus. Select Type 1 sets: software; input output for paper and trays; the type of interface; and miscellaneous (reset, recovery, HP memory allocations, and saving resetting configurations).
Select Type 2 sets: serial port protocol; and startup default general options such as the beeper and whether to print a test page every' time you fire up the printer. The test page prints a memory check and how many pages you've printed total. At each Select Type, there are selections to reset to factory defaults, or to save your own defaults in persistent memory'. You may select anything the printer can do from the menus as well as from software in PostScript interactive mode through the serial interface using a superset of the printer's control panel settings.

Whenever you have the possibility of getting into trouble, warnings are prominent and dear. The exact procedure for things such as shaking the toner in the imaging engine are diagrammed. Complete tables of factory defaults and printer specifications including paper specs and sizes are listed, it is a wonderful manual. There is a matching companion manual that serves as a supplement to the PostScript Language Reference Manual (not included, published by Addison
Wesley). It will be of no help unless you also have the PostScript Language Reference Manual which is a necessity if you are to operate a PostScript printer with any degree of confidence.
There is scant information in either manual about how to use PostScript or its fonts; they leave it up to your software application or the Language Manual to explain this. They do include some example illustrations of the things PostScript can do, and a listing of the fonts with examples of what they look like, however. 1 would have appreciated a little more information, but I understand the omission: the PostScript Language Reference Manual is an inch and a half thick! How could Epson ever condense all that information into anything useful?
Conclusions The Epson EPL 7500 met all five of my criteria, and exceeded my expectations. The (street) price is surprisingly acceptable and yet it is a true high-end PostScript printer with the latest PostScript interpreter in ROM. It does a transparent job of emulating HP LaserJet!! Mode as well, and has convenient slots for HP font cartridges. Thanks to its RISC processor, it has a quite acceptable speed of six pages per minute that is relatively unaffected by complex graphics, and the Minolta self- contained imaging engine is designed to be trouble free using the replacement method of
maintenance, rather than the messy chore of using loose toner. The Epson EPL 7500 has a small footprint, takes up little space, and at 40 pounds is relatively light weight for a laser printer, but it is ruggedly built and rates highly in the form fit function category. There are options for upgrading the memory to 6MB, a face up output tray for transparencies, stiff paper and envelopes, and a bottom paper tray that adds an additional 250 sheets to the standard 250 sheet tray capacity. Paper may be fed through the tray or by single sheet.
Envelopes feed and print just fine, as the paper guides are fully adjustable. Maintenance is simply a matter of routine replacement of the imaging engine at about 6000 pages, cleaning the paper path as needed, and replacement of the ozone filter every six months. The printer consumes only 550 watts of electric power instead of the more usual 750 watts of its competitors. Finally it implements the entire standard 35 fonts of the PostScript language and meshes seamlessly with drivers supporting standard PostScript fonts such as those of PageStream2 and others. I have no regrets at ali
about buying the Epson EPL 7500, and recommend it strongly as an ideal mate for your Amiga and your DTP software.

REV 1 E W S The Word is that the general release of AmigaDOS V2.0 was so late because a lot of significant software broke under the early versions. So far the effort to ensure upward compatibility seems to have paid off. With one possible exception, none of my "serious” software has had problems under the new operating system. Still, as a reviewer of games, whose programmers frequently have the attitude "bust the rules if you have to, but squeeze the last ounce of performanceoutof the hard ware," I was decidedly uncomfortable with the thought that the ROM swap might cause games 1 had

DKB Software's MultiStart II board for the A2000 A500 allows up to three Amiga OS ROMS to be present in a computer atone time.
One ROM can be chosen as the default used on power up. One of then ther two chips can be selected as the alternate which can be activated from the keyboard. In a dire emergency, a jumper on the boa rd can be used to switch which of the secondary chips is used as the keyboard alternate.
DKB SOFTWARE'S MultiStart II Board by L. S. Lichtniann Upon power-up, the default ROM will determine the operating system version. Warm booting the Amiga retains this OS. However, if the CONTROL LEFT AMIGA RIGHT AMIGA key combination is held down for five or six seconds, rather than the usual momentary press, the OS in thechosen alternate ROM will be used upon reboot. Subsequent warm boots will retain this alternate OS, until the five-second hold-down procedure is repeated, returning the system to the power-up OS.
Installation of the MultiStart II is straightforward, but requires some ca re. The existing ROM chi p must be removed from its socket.
The two. Or three desired ROM chips must be installed in the sockets on the MultiStart board, and the board pushed into the vacant ROM socket on the Amiga motherboard. Finally, a jumper wire attached to the MultiStart board must be run to one of the pins of the "Gary-" custom chip on the motherboard. The wire lias a ci ip connector on i ts free end, so no soldering is required. The procedure is clearly detailed in the MultiStart Board's manual, with customized descriptions for both the A500 and A2000.
What I found less than satisfactory, however, was the jumper wire. Its length was really too short to reach the appropriate pin.
Worse, it had been attached to the MultiStart board without any strain relief, and while being uncoiled from its shipping position, it snapped off right at the board.
Fortunately, a few minutes with a soldering iron, a splice with a few inches of fine wire, and some fast moves with a little shrink tubing were sufficient to repair the damage and eliminate the length problem. (DKB now ships the hoard with a 7-inch jumper wire. F.d.) Once in place, everything worked perfectly. The board has already proved its worth on one new game. Millennium, which I couid not get to run under 2.0. The list price of S99.95 might be a little on the steep side, but if you need the MultiStart 11, you probably need it badly.

to recommend the board to anyone withoutaccess to electrical tools or without a little experience in electronic repairs.

P. O. Box 2140 Full River, MA 02722-2140 former example is
similar to the switching functions built into the Video
Toaster; the latter function can be done by any Amiga genlock
The Video Toaster and the Video Blender share some similar attributes, but the Blender can do things the Toaster cannot and vice versa. One example of a Blender fea tu re not a va ilable in the Tbaster is a dual input stereo audio mixer that is fully controllable from the Video Blender software. In this review, I will stress the specific capabilities built into the Video Blender so that you can make a determination as to whether the Video Blender can deliver the features and functions that fit your desktop video needs and your budget.
Let's start off with a description of the featu res that the Blender can provide foryour desktop video workstation. The heart of the Blender is a standard Amiga genlock with four modes of operation. The modes are defined as foreground, inverted, mixed and encoded; and genlocking can be performed with any standard Amiga titlingorgraphics package.
The Blender can also control genlock functions manually from dedicated function keys, which you define, or called automatically from a script. The Blender performs genlocking functions and PROGRESSIVE PERIPHERAL S' Video Blender by joint Steiner In the beginning there was video titling software and the composite video output from the original Amiga 10U0. Then the genlock was born, bringing about the ability of the Amiga to overlay graphics over live video. Then came the Video Toaster, a truly powerful video switching station with 24-bit image-capture capabilities and a complete set of
software, which includes a built-in 3- D animation, paint software, special effects generator, and character genera tor. The Toaster has become the standard by which all other Amiga video peripherals will be measured against.
When I first heard that Progressive Peripherals was devel- opingn "VideoBlender," I thought that they were developing a competing product and making another reference to a kitchen appliance. After using the Blender for some time, I have concluded that the Blender and the Toaster are not d irectly competing for the sa me customer. Not only that, unlike the Video Toaster, the Blender is aptly named because it does blend video signals in several ways, some of which are truly unique. According to Progressive Peripherals' manual "Examples of video mixing include displaying portions of
two different video sources as one image, or simply fading or wiping from one video source to another, Another form of video mixing involves merging live video and computer graphics together."

Transitions from any two of four possible sources, corn posi to v i d co, Amiga graphics, RGB video and a local 16-million color background screen, fades and transitions can be precisely timed from li to 10 seconds in .04 second increments.
Video mixing can provide double exposure or tinting effects. Automated switching between sources provides many special effects, and a notch filter helps to sharpen the edges of a transition. Software utilities allow you to create and modify-' custom wipes and include them in your video presentations.
Thebuilt-in stereo audio mixer can also be operated under manual or automatic control. Audio fadescan also be precisely timed from 0 to 10 seconds in .04 second increments.
One accessory that is not available at this writing is an optional S-VHS video switcher which allows S-VHS equipment to work with the Video Blender and Progressive's Rambrandt 24-bit graphics board. The switcher can beconfiguredfor A- Broll (wipes) between two VCRs. This application would require that each input VCR signaI be time-base corrected.
Hardware Description The Video Blender is an external component. The circuitry is housed in a metal box that is about the same depth and width as an Amiga 3000. The unit stands just over 2.25 inches tall and fits nicely between your monitor and Amiga 2000, 2500 or 3000. The Blender also works with Amiga 500 and 1000 CPUs. The package includes a serial cable, which is necessary to connect the Blender to your Amiga system and also includes four BNC to RCA adapters in case you wish to use cables with RCA connectors instead of the video industry-standard BNC type.
Power to the Blender is provided by a large "brick"-style black box power supply, which can be placed on the floor or in some other out- of-the-way location. The Blender is nicely finished with attractive screen-printed nomenclature on the front and rear panels. All controls are located on the front panel for easy access. The controls allow adjustment of hue,satu ration, and Tell Our Art Department To M Weekends You have a deadline coming up, and the pressure is really on.

The rear panel connectors allow a lot of flexibility in connecting external equipment. 1 lere is a short description of each o f the rear panel connectors. The Video IN connector locks the
Amiga's video sync to the equipment supplying video at this jack. An RGB input consists of three BNC-type connectors,one each for red, blue, and green. Wi th this input, you can connect anv video equipment which outputs separate RGB signals, if you connect an RGB-equipped, genlockable camera, you can use the Blender to switch between it and the master video input (or any of the Amiga signals) without requiring a time-base corrector. 1 view this input to be of limited usefulness for the semi-profescontrast for the video output signal and audio attenuation controls for the dual input
audio mixer. A power switch and indicator light are also located on the front along with the four RCA-type audio input jacks for the audio mixer.
The rear panel is chock-full of connectors. There are so many, in fact, that there is not room for the audio input connectors which are placed on the front. This unfortunate necessity mars the streamlined appearance of thefront panel, requiring you to run audio cables a round or under the unit to connect to the audio inputs. On the positive side, if you routinely change auviewing of the master video input source. A 75-ohm terminating switch is provided for this output to allow proper impedance matching, whether or not a monitor is connected. Two other video connectionssupply Black
Burst for videosync and External Key Input for connection of special video keying devices such as a Chroma Key.
Left and Right Audio Output connectors are provided todeliver audio to the recording VCR or other appropriate output device.
The only two connections which connect to your Amiga system are an Amiga 23-pin RGB passthrough port and a 25-pin serial port. The 23-pin cabie that comes attached to the Video Blender is connected to your computer's RGB Video port, and the standard Amiga RGB monitor cable is connected to the 23-pin port at the rear of the sional or amateur videographeras RGB cameras are not likely to be readily available.
There are two Video Output connectors, each containing the same video information. One of these is connected directly lo your final output device, usually a VCR, and the other is connected to a composite video monitor to provide a practical means of viewing the video thatis being recorded. In my system, I use a 1080 monitor to view the signals I'm recording. A Video Through connectorsupplies a signal that isidentical to theVideo IN connection that could be connected to a monitor to allow easy LDV-2200 laserdisk player, which is also controlled through a connection to the Amiga serial
The genlock I am currently using in this application is controlled through the parallel port, and the video disk and genlock get along just fine. 1 was hoping to use some of the excellent special effects and audio mixing features that can he implemented in the Blender to liven up my presentations. It appears that I will be required to obtain a multiple serial port card.
Whether the Blender and a video disk player could he controlled from the dual serial port via an AmigaVision application is something 1 was never able to lest.
The last remaining connection on the Blende)' Is for the power supply cable, which leads to the power brick. The brick has an AC power cord attached as it is too large and heavy to be plugged diBlender. If you are using a deinterlacing board, or have an Amiga 3000 with built-in deinterlacing, you can ignore the RGB passthrough connector on the Blender and use the deinterlaced video connection as you always have.
Communications lo the Video Blender are provided through a serial cable, which is connected between the Amiga and Blender serial ports. This connection frustrated my original purpose for using the Video Blender. I was planning to use the Blender for AmigaVision multimedia presentations.

Software Installation I was able to install the Video Blender software without a hitch.
The included installation program will even create the drawer in which you want to place the software. There are twodisks included in the package, the Blender disk and an Accessories disk. Once the installation is complete, the documentation provides a testing technique to make certain that the Blender is fully functional.
Video Blender Software There are six major software applications which were developed for the Blender. A description of each one of these programs is listed here.
VBPanel, the Video Blender’s Control Panel This program controls the Blender hardware and allows you to create, define, and preview video "events.'' An event is defined in the manual as "...anything that causes a change in the current video output. An event may be as simple as a 'fade to black' at the end of a scene. An event may be quite complicated, involving keying effects, or graphic and sound overlays." You will start learning about the Blender with the Vbpanel as it is the too! Most used for operating the Video Blender manually. Starting in the upper left corner of the screen, the con
trols marked Event Keys are used to define up to 50 events or non- events. An event can be described as a programmed change in the status of the Blender hardware. A non-event can be described as a function key that is not defined.
The advantage of this feature is that if your titling program uses function keys for its own opera tion, you can still use VBPanel by defining kevs used for other programs as non-events, in that way accessing those function keys will WE ARE AMIGA' HEADQUARTERS!

You define an event bv selecting a function key, for example, click on Ctrl, then click on 4 to define Ctrl - F4. Then define any combination of key mode, channel mix, local color, key level, audio level or ex
ternal task. Save that definition using the Event Control file requester which is accessed in the Event Control portion of the panel.
Once you have defined all functions needed for your presentation, bring up the Session Control file requester and save the entire session. Key Mode allows you to determine which of the four genlock modes you wish to activate. Mix Channels allows switching between bus lines B1 and 132.
When Bckgnd mode is selected, the lower half of B2 is activated allowing you to mix or overlay any two of the four video sources on the output bus. A, R, C, and L represent Amiga, RGB, Composite and Local color sources respectively.
The lower left of the screen contains sliders for mixing percentage on the B2 bus. The dual sliders can be set from 0 to 100%, or you can click in the box below the slider and enter a number directly. The D slider programs the time it takes for the mix to change from its previously defined setting to its new setting after you press the currently defined event key.
The dual slider can be set from 0 to 10 seconds in .04 second increments. As with the Mix slider, you can also click in the box below the slider and key in a specific time delay. Located immediately to the right of the Mix sliders, the Luma slider adjusts the threshold at which keying occurs between the Primary (P) and Secondary (S) inputs on bus 2.
The Blender is aptly named because it does blend video signals in several ways, some of which are truly unique.
The three sliders labeled R, G and B on the Local Color section can be set for any- value between 0 and 255, allowing the creation of a local color screen that can be used as a background to overlay graphics, or to luma key behind live video among other applications.

44 A MAZING COM PUTING The ExtemalTask component in the lower right of the screen allows you to select a workbench applica tion, a CLI application, or a batch file. The tutorial that covers this function fell apart because of changes in the programs that were included with the Video Blender release version. I did have some limited success in calling external tasks, but it was not as simple as 1 had expected. When I called Progressive's technical support line, the person I talked with commented that 1 would get better results by using the VideoScriptor and Slides utilities to perform
functions that might otherwise need to be done by an external task in VBPanel. In the case of the tutorial, they were attempting to use an external IFF file viewer.
VideoScriptor can display IFF files and ANIMs internally. I can imagine that I might have to use an external task to control a video disk player, and 1 am not sure if that would be possible given the problems I had. Much of theprob- lem I encountered was related to the ability to hide specific screens from view. It is possible to tell VBPanel to hide the screen that the external application uses. 3 couldn't get this function to work consistently, and 1 am not really sure how much of the problem is related to the changes made in the release version files.
Once you have created your session in VBPanel, you can then hide the control panel and control your presentation directly from the event keys you defined- There is sometimes a slight delay between pressing an event key and its subsequent effect occurring. This is so because of theextra overhead built into the editor. VBPerform contains only enough of the program to present sessions created in VBPanel, and consequently operates much more quickly. What this means is that once you have created yourpresentation, you should use VBPerform to control it.
VBPerform This program functions as an externa! Task, enabling all of the pre-defined events created originally in VBPanel. It, in effect, turns your keyboard into a ddeo event player. You can press the pre-de- fined function keys as your video is being recorded, and since VBPerform doesn't have its own screen, it won't interfere with graphics or titles being displayed.
VideoScriptor, the Automated Script Generator This program allows you to create a script that contains delays, and standard or custom wipes and otherwise automate the activation of video events, VideoScriptor uses a graphical user interface that allows the quick creation of relatively complex presentations. Figure 3 shows the main VideoScriptor screen. A complete description of the workings of the program would take more space than 1 have in this review, but the genera! Idea is to choose buttons to select items to be included. On the bottom left, Wipe is highlighted, and the area
above Wipe d isplays a list of wipes to select from. If IFF were highlighted, a file requester showing a list of IFF images and animations would be displayed, if Custom were selected, a list of previously created scripts wou Id be presented that could be included in the current presentation. If Control were selected, you would see a list of previously defined VBPanel events. When you select an item on the left side of tire screen, it is automatically added to the script on the right side. If a command requires an argument, such as DELAY 180, the program will insist thntyou provide the
I used the VideoScriptor program extensively to create many sample scripts and did not run into any major problems. I did not, however, try very sophisticated scripting. In fact, if you really want to take full advantage of the Slides program, you will learn how to edit and compile your scripts from the CLI as you will be able to complete many of the most powerful features of the Slides program. The manual contains a complete programming section for SI id es which identi fies tlie function and usage of every command in the language.
Slides, Video Blender's Automated Presentation Program The Slid es program reads and executes the scripts created with VideoScriptor. In addition to controlling events, Slides can display images and animations as well as perform standard and custom wipes. The program can perform all of the functions which can be accomplished in the VideoScriptor, and additionally perform other commands in a sophisticated scripting language that is more powerful than the basic VideoScriptor program can create.
You can use a text editor to create complex programs or modify programs tha t were original ly created in VideoScriptor to take advantage of the greater power built into the Slides program. Like VBPerform, Slides runs as a background task which won’t interfere with any images which are currently being displayed.
Automated switching between sources provides many special effects, and a notch filter helps to sharpen the edges of a transition.
This program reads a binary script that was prepared in one of two ways: A) Written in a text editorandcompiled;or B) Created by the VideoScriptor Automated Presentation Generator. Slide can perform fivedifferent tasks: 1) display IFF images and animations,
2) execute any of several built-in wipes, 3) play previously
written scripts, 4) externally control VBPanel, and 5) provide
timed or cued delays. Slides must have a script, and does not
have its own visual interface. The language that Slides knows
is relatively simple to learn, and quite sophisticated for its
simplicity. Even so, learning a scripting languagecanbea time-
consuming process which can take many hours of study before
you would be ready to complete productive work on your Video
MixMaster, An Automated Wipe Generator.
This program is really a two- color paint program that allows you to create your own custom wipes. These wi pes are simply two color animations where color 0 is geniocked to live video. Though you could use any paint program to create animated wipes for the Video Blender, MixMaster has several features and built-in functions which arespecifically tailored to the task of generating animated wipes.
When you start MixMaster, you will see a screen similar to the one on page 42, This is really two screens, the menu at the lower fourth of the screen, and the background which will contain an animated wipe when you are finished.
If you have used animation programs such as DeluxePaint or Animation Studio, you will feel pretty well at home working with MixMaster. The tutorial had me making several very nice AnimWipes in no time at all. The program has the ability to use 10 built-in brushes and 10 custom brushes which are stored and retrieved using the numbered interface on the right hand side of MixMaster's screen Remember, these animated wipes are created as two-color animations with the transitions occurring between color 0 and color 1 in your animation. Though I missed some of the more powerful features lam
used to using in DeluxePaint, most of the time MixMaster functioned to my expectations. In fact, I tried to use Dpaint to create my own animated wipes, and gave up as MixMaster worked much better. I was hoping to improve upon the wipes by loading them into Dpaint once they were saved as an anim, but I had limited success with this.
They ivould come into Dpaint at the wrong resolution, or in a different size, and generally my attempts to modify these anims ended in failure. Once you have created a wipe in MixMaster, you can then use the wipe in scripts that you create for the Slides program.
Wiper This program allows experimentation with what the manual describes as "over 24,000 standard (algorithmic) wipecombinations."
Video Blender Documentation The package includes a 264- page manual that is complete and reasonably well indexed. Itis written well but suffers from a common problem which besets the first release of any major product. It was developed before final product release, and last minute changes in thesoffwaremakeparts of the tutorials incorrect, leading a beginning user toconfusionat best, and at times makes continuation of a tutorial impossible. A "readme" file speaks to some of these changes, but that doesn't always help when you are trying to understand a complex function that doesn't
appear to work as described in the manual. The manual includes two Quickstart tutorials and seven comprehensive tutorials. Some of the tutorials cannot be completed in their entirety unless you have an RGB camera at your disposal. This is not a major disadvantage as you won't need to complete those tutorials if you don't have the camera. Otherthan tire aforementioned glitch regarding final release software, the tutorials are quite well done. They assume no prior knowledge and begin by defining proper hardware connections for performing each task. The Video Blender is a powerful

Its presentation capabilities are far superior to the tvpicnl Amiga genlock device, and yet it costs only somewhat more than many of the high-end genlocks. If ali you need is
genlock capability, you should probably consider several quality units that are now available for less than $ 1000.

P. O. Box 2140 Fall River, MA 02722-2140 Many of my recent
columns have dealt with synthesizers and MIDI sequencing.
While this is definitely the best way to prod uce high quality
music on the Amiga, the internal sound chip is surprisingly
capable of producing good sound. This month we'll look at how
you can use audio digitizing (also known as sampling) to pro
duce instruments for Deluxe Musk Construction Set, SONIX,
and other Amiga music programs.
MUSIC If a signal level is too high when recorded, the result is "clipping" distortion.
Notice the top of the waveforms.
The first requirement is an audio digitizer. I've used both the Mimetics and PerfectSound digitizers with good results, but there are many others available that will work equally wel I. Most plug into the Amiga's parallel port, but the Mimetics digitizer uses the second mouse port. The second requirement is a way to get sounds into the digitizer. You can either use a microphone or hook up a CD or tape player directly. The advantage of a direct hookup is that no background or room noise wi 11 be recorded, providing a clean sound to the digitizer. In addition, a direct hookup will often
allow you to control the level of the incoming signal, an important factor in recording good quality samples.
Similarly, a separate microphone preamp can improve sample quality by boosting the microphone signal before it enters the digitizer.
A third tool that makes life much easier is good sampling software. White most digitizers come with software to make simple recordings, the software may not be optimized for visual editing and making IFF instruments, Editing software, such as AmiioMaster III or Audition Four, can easily create instruments and special effects like echoes.
Finally, you need something to digitize! This can be the sound of your voice, household appliances, musical instruments, or the latest CD. If you're interested in instrumental sounds, but don't have access to an orchestra, you may want to consider the sampling Cds that several companies sell. These typically provide samples of a variety of different instruments, ready to be digitized.
Sound Effects Cds and tapes are also available. If you aren't trying to recreate a particular instrument, you might just look around the house for things that make an interesting sound.
Once you have the right hardware and software, you must choose the sampling rate. The higher the pitch of the sound, the higher the rate needed to capture it without distortion. Thesampling rate must always he twice as high as the highest frequency you want to record. So the answer is to use the highest sampling rate your software and hardware support, right? Not necessarily. Higher sampling rates use more memory and aren't supported by Amiga IFF instruments, A sound sampled at 28 kHz takes twice as much storage space as one sampled a 114 kHz. Amigas have a low pass audio fil ter that
eliminates almost all frequencies above 7 kHz, anyway.
The bottom line is that you need to use a high enough sampling rate to catch the high frequencies, but may not need to use the highest rate available. Some software can "resample" sounds using software algorithms to reduce the amount of memory required while keeping the sound at its proper pitch.
This allows the software to create better quality IFF instruments.
This is the best reason to use a high sampling rate, since ordinarily rates above 18-19 kHz won't be supported by IFF instruments.
After you've got the right sampling rate and have a clean sound source, the next step is to set the input level the most crucial step in the process. You want to record at a high enough level that you will get the maximum signal to noise ratio. However, you also want to be careful not to overload the input bv using too high a volume setting. Most digitizers have input controls; if they don't, you'll need to control the volume at the source. Signals recorded at too high a level result "clipping" distortion. The tops of the waveforms are clipped when they exceed the digitizer's range and
theclippingisaudibleas harsh distortion.
A better recording has lower peaks and no clipping distortion.
However, if you set the level too low to avoid dipping, you may end upwithasignal thathasa low overall volume level. One way to avoid this problem is to compress the signal before digitizing it.
Compression lowers the volume of the loud partsof the signal while letting lower level sounds pass through. A compressor will allow you to record at a higher overall volume level without dipping, improving the average signal to noise ratio. When comparing a recording with compression to a normal recording, the compressed sample has higher peaks, especially at the tail end of the sample.
You can use other effect devices to alter the sounds you want to sample. Echo and reverb enhance many instruments; by digitizing samples with the effect "built-in" you can use one effects device on several different instruments. Radio Shack makes an inexpensive "echo box" which will work, but if you are serious about digitizing you may want to purchase a dedicated effects device.
Some software allows you to create echo effects by highlighting a (Continued on p. 92) Left: "Trout", by Germantown Academy student Michael Cole.

Video Toaster Backgrounds Creating backgrounds for text with the Video Toaster i s fai rly easy. The Character Generator section of the program provides a method to create a smooth gradient spread from one color (the top of the screen) to another color (the Writing n novel, filming a movie, printing a newspaper some forms of medium are foreboding merely by the vast amount of expertise and work involved.
Not video. Video is a medium that these days almost anyone can do.
Low costs have put video in the hands of just about everyone.
People have also been gradually lowering their standards as far as production values and formats, with camcorder shot news items all the way to "America's FunniIntroducing a monthly feature on Amiga video, designed to help and inform the Amiga user.

Bottom of the screen) when creating a frame page, with the default spread being green to blue. The 2 color spreads are nice but tend to get a little boring after a while. Art Department Pro and DCTV both can create great multicolored backgrounds, but they arc separate programs, leading to multitasking, fileswapping, and 1FF24 to Toasterframe conversions.
Wouldn't it be nice to create backgrounds with four or six or 10 differentcolor spreads from within the Toaster? Well..you can! Most Toaster users are at least somewhat familiar with the ChromaFX portion of the program.
ChromaFX is similar to a set of photographer filters, allowing the user to run video through variations of colored effects based on the luminance (black and white) of the incoming signal. Chances are you played around with it when you first got your Toaster, and aFter previewing the built-in dizzying color effects decided you wouldn't have much use for changing the world to mind- numbing shades of orange and pink.Truthis ChromaFXhns many hidden uses, and one which I discovered is using it to create gradient backgrounds on the fly. Even if you've never used ChromaFX, just follow these
step by step instructions and you'll have some beautiful backgrounds to save as frames in under five minutes:
1. After booting up the Toaster, enter the ChromaFX "slice" to
the left of the ToasterPaint icon. On the top of the ChromaFX
screen you'll see an Effects Selection bar.
For now leave it in the default effect which is "00-Posterize."
2. Right below the Effects Selection bar is a toggle for
Blurred and Sharp Transitions along with a Posterization
slider bar. One icon shows a blurred transition and the other
a sharp one, the sharp one being just two solid colors. Click
ing the sharp one on the right and moving the Posterization
slider below towards the right will gradually "unsmooth" the
transitions between colors. You'll see the results in the
large shaded bar (Palette Map) just below the Posterization
slider. For now we want the left Blurred Transition icon
selected and the slider moved to the absolute left side.
3. Below the Posterization Slider is a large shaded bar called
the Palette Map. Click on the Darkest Box on the leftside of
this bar. This selects the position of the first color we will
4. Next click on the RGB icon below. Move the R (red) slider
about 75% to the right, leaving Green and Blue all the way to
This will produce a dim red. Then dick on the HSI slider and move the H (hue) to a desired color. Any will do for now..we're experimenting!
Creating backgrounds for text with the Video Toaster is fairly easy using the Character Generator or the ChromaFX portions of the program.
5. Select the Lightest Box on the right side of the Palette Map
bar (you'll notice the black line called the Palette Marker
will jump to the right side of the spread this let's you know
what color you are changing). Repeat Step 4, selecting a
color using the Hue control.
Any color is fine but it should be different than the first one we created.
6. After creating a color, select the Horizontal Spread Button
(asingic straight line icon right betow the Palette Map bar).
The black and white spread in the Palette Map will change lo a
smooth gradient blend between your two choosen colors.
7. Below on the screen there is a separate window called the
Color Table. In it you'll see the colored spread vou just
created near the top of the window and a grey scale spread
near thebottom. We've just created the colors for the top of
the page, now we not'd to do the bottom half. You'll notice
there is an arrow selected to the right of the Color Table at
the top, letting us know we are working on the top spread.
Click the arrow on the bottom right of tire Color Table
disregard the "dual arrow" icon for now. The Palette Map above
swi tches lo g rev sea les to show we are now ready to edit
the colors in the lower part of our screen.
S. Repeat Steps 3-6 to create the lower two colors.
9. Below in the Color Table you'll see a small representation of
the final background screen. Click on the Clapboard icon
directly above the cancel icon. After a few seconds of
rendering your arrow pointer will return. Select OK.
Now that you're back in the switcher click on DV1 on the program bus,.there's your background! It has been rendered to Hie Toaster's framebuffer meaning you can now save it if you wish. To save it click on the Save Frame icon (lower-right picture of a frame with an arrow pointing to a disk), type a three-digit number with the Amiga kevpad, click inside the blank filename requestor above the number requester and type in "background 1." Then hit enter on the Amiga keypad twice. You don't have to save the background if you already had some CG key pages pre-made to cue up over
it...just roll tape and go. However if you needed to enter the CG to create new key pages, theCG editor normally dumps DV1 for testing purposes which would requi re the background to be re-rendered or loaded from the hard drive.
Wouldn't saving a lot of 1M B background frames use up a lot of hard drive storage? You bet. So here's a better solution: In case you didn't know..savinga project also saves all your premade ChromaFX color effects along with other items such as CG pages. So after you've created a colored effect following the above steps, go to the top of the screen lo the Effects Selection bar in ChromaFX and using the arrows go to the next "slot" after "00-Posterize" and create your next masterpiece.
After creating several premade patterns exit ChromaFX (select OK) and from the Switcher go in to Preferences and select the "Save to Disk" icon (pointing to the d isk) in the Project window. These colored backgrounds will now be available for rendering every time vou boot up vour Toaster. Consul t your manual for more info on creating multiple projects and default projects.
Some of the gradient backgrounds will suffer from "banding" where you can see the colors change. This may be desirable, but it can be eliminated by color experimentation. Also try to keep colors dim. Background screens are for the background; they shouldn'tbe fighting your text for attention. Also try black and white grey-scale shades for a real professional polish. These backgrounds are not just limited to the CG, they can be loaded right into ToasterPaint for creating title screens, rub-thru effects, and other uses. In fact by using the darken and blurcommand inToasturPaint you can
dull the screens if needed.
They canalso be used in Lightwave 3D. I've used them for everything from texture maps, bump maps, and reflective maps (see article screenshot). They also make great 3Dbackgrounds, just load them in via the "Load Background" requester i n Lightwa ve 3D after saving them as an RGB frame with ToasterPaint. In fact once you convert them to an RGB frame (actually an IFF24-bit image) you can use them in any program that supports the IFF24-file standard such as The Art Department Professional.
So what do those other buttons do in ChromaFX? Well go through the above steps and instead of selecting the Horizontal Spread button choose one of the three other buttons to the im mediate right: Horizontal Spectrum, Random Color, and Snow. By the way, you're not limited to two color spreads; you have up to 96 colors to cha nge i n the Pa lette Ma p!
You can click anywhere in the Palette Map and change a particular color: 1. Click on a color inside the Palette Map bar (you'll see the black Palette Marker jump to that location), 2. Change it with the RGB HSI sliders, 3. Click on Horizontal Spread, and 4. Choose another color somewhere else in the bar. It's that easy. After your color spreads are finished try clicking on the seven buttons to the left of the ColorTable window for more variations. By the way, the "dual arrow" button mentioned above is actually the Exchange Color toggle; it's OK to try (continued on p. 54) Do You See a
Change in Color?
By John Iovine Do we really need 24-bit color? Let me answer this question right away; despite all the promotion and products to the contrary, in a word no. Before you throw this article aside in the belief that I'm a little off the color wheel, allow me to present the information as I see it, pun intended.
First let's define 24-bit color. The 24 bit derived by the addition of the three 8-bit color components; red, green and blue (8+8+8 = 24). Each of the 8-bit color component numbers can represent one of 256 possible levels. When we multiple the 256 levels by each of the three color components we get 256 x 256 x 256 = 16,777,216. This is how the 16- million-colors-possible claim is derived for 24-bit color, 16 Million Colors for Whom?
If we wanted to display all of the 16 million colors at once, our monitorscreens fall pretty short. You seen 320x200 screen only contains 64,000 pixels so the maximum number of colors that could be drawn on the screen is64,000. And that's assuming every pixel isa different color.
Likewise a 640 x 400 screen contains just 256,000 pixels. So it would be impossible to show all the 16 million colors available at any one time on a screen. So the 16 million colors are reduced to a color palette from which one can choose colors.
Even more important than the screens resolution is the information that can be obtained from 24-bit color systems themselves. A histogram graphs and identifies the colors used in digitized pictures. Of all the histograms I have analyzed of 24-bit color pictures, not one ever came close to using all the colors available. Typically full color pictures use only 100,000 colors. Out of this more than half were single bit colors used onlv once. Usually these pictures could compress their pixels colors 3:1 without any degradation of image quality.
More important than the information contained in a histogram, is the visual color acuity of the human eye. Color perception varies from person to person. On average you need about a 1.5% change in color some people require greater than 1.5% to notice a difference. Each change in level of an 8-bit (256) color component represents about a .4% change. Therefore the level would have to step at least four times before a difference could be perceived. And the difference itself would be so slight and subtle that chances are it would not significantly affect the picture quality.
If you look at the in formation th us presen ted, I sure you will be lead to the same conclusion that I have that 24-bit color systems are really an overkill.
Drawing the Line My belief is that color resolution could have proceeded to 18-bit color and stopped. Here each color component uses 6 bits per color (64 levels). Each change in level represents a 1.56% change, which matches closely to the perceptual resolution of the human eye. The color palette (64 x 64 x 64) of 262,144 colors would be more than enough to accurately represent full color pictures.
Does this mean that someday soon someone will put out an 18-bit color system? Probably not. It would be a marketing nightmare to compete against 24-bit systems regardless of the fact that no one could differentiate between a 24-bit and 18-bit picture.
The Resolution Revolution The idea then is not to try to turn the clock back, so to speak, to an 18-bit system, but to resist any further increase in color resolution like 32-bit or 48-bit systems (a la Mac). By doing so, one sendsa dear message to the manufacturers to put their money into other features of the program or digitizer.
I’m sure the contents of this article will be bitterly debated and categorically refuted by various manufacturers currently selling 24-bit color devices. I'm not attempting to stall theevolution of video, but there comes a point where further development in a particular area such as color resolution has already passed the point of the human eye's ability to perceive it. The eye's ability to perceive subtle color changes was passed at 18 bits of color. So why 24-bit color? Well it sounds nice doesn't it? 24 bits, throw in some "broadcast quality" quotes, and you're cooking.
Simple Program Although the Amiga is incapable of displaying the subtle changes in color of an 18-bit or 24-bit system, we can manipulate the palette, and use our imagination.
The basic program is quite simple; when it is run, a red block is painted in center screen. The block is actually made up of two smaller rectangles. Pressing the "u" and "d" key changes the percentage of red in the palette of the rectangle on the left side of the screen. The changes in the palette arc displayed above the rectangle. In the display 1 = 100 percent and the decimals, note the percentages less than 1.
On my display I need to bring the red down 10% points before a change can be seen. Subsequent changes required 6 or 7% points. The reason it takes such a large percent to see a change has to do with the stock Amiga display, not with the visual color acuity of the human eye.
Regardless, look at the display with just one increment of change between the two rectangles. Now imagine that with an 18-bit system there would be about four shades of red between the two red colors that you would be looking at. Many people wouldn't see a 11 the sha des. Wi th a 24-bit system there would be 20 shades between the two, and you definitely couldn't see all the subtle color differences.
The program is quite simple and is easily' modified to change the green and blue components as well as the red. For anyone thinking about modifying the program to operate in HAM mode, this will not improve the color resolution of our test program. The color change that can be derived by modifying the palette is the optimum for the stock display.
In Fairness There are advantages to 24-bit color, but unless one is involved in some heavy duty image enhancement projects, the use of 24-bit color or greater is superfluous. By "heavy duty" 1 mean something on the order of enhancing a satellite image of the earth to track schools of fish in the Atlantic, or analyzing the geology of Mars to look for dried river beds.
Here pixel differentiation that cannot be seen with the eye may be enhanced with the computer to bring forth details that would otherwise go undetected.

In addition to freelance video work I also use the Amiga for more creative a renues such as producing movies (which we'll get into in later issues). Although the colu mn will center mainly on using video in a prosumer and professional atmosphere, we'll cover the creative and entertaining side of Amiga video as well. . _

Besides the nearly infinite in tend ed uses, users often find interesting things that can be done with the program that were never imagined. This is known in scientific circles as "Synergy," a
phenomenon where the whole, working together, is greater or more unpredictable than the sum of the parts.
The most popular software tool for the Amiga has undoubtedly been Electronic Arts' Deluxi’Pnint in all its versions. After years of exploring its nearly perfect combinations of tools, I've stumbled upon a strange and wonderful process thatcan create striking, delicate abstract paintings, and dazzling animations almost automatically. No artistic skill is necessary, though a good eye and a sharp imagination can be helpful. All you have to draw is a single straight line.
I call this unique, nearty-automatic process "Semi-Automatic" painting, and its effects vaguely resemble fractal designs. Unlike fractals, however, you don't need to be a math wizard to exert specific control over the finished product. To get started, you will need either DeluxePaint III or IV and 1MB or more of RAM. For our first example, start by drawing a long line and picking it up as a brush. Press Alt-z to grab a handle at one end of the brush.
Stamp it down with the handle near the center of the screen, like a clock hand. This tells the computer where to start. Tap F10 to clear the menubars. Now choose MOVE from the ANIM menu (shift-m). Select a high COUNT, such as 300 or more. Type 360 in the Z ANGLE box, and click the PREVIEW button. PREVIEW allows you to test the path of your brush across the screen before all of the rendering starts.
Click on DRAW. Now sit back and relax as your Amiga doesall the hard work. This simple example will produce a starburst with moire pattens. It takes a while, but part of the fun is watching your painting take shape.
Here'sa method of making a perfect snail- shell spiral. Draw a one-inch dot and pick it up as a brush. Press Alt-z to grab it from about six inches away from the circle's center. Stamp it down slightly off-screen as a starting point. In the MOVE requester, select 400 or more in the COUNT box. Tap in 7200 for the Z ANGLE, and about 4500 in the Z DIST box. Trv a PREVIEW.DRAW. Try it again, but with CYCLE mode on. Hit your Tab key and watch the show. Your Amiga should begin drawing your brush in a delicate whirlpool around the screen, it may take a white to complete, especially if you're in
lii-res. If the spiral doesn't crawl to the center of the screen, just press shift-m to bring up MOVE and hit DRAW again. Repeat if necessary. This will continue the brush’s journey to the middle.
Perhaps you can set up arangeand select cycle mode to slowly shift through the palette as it's created. Color cycling turns your S-A painting into something really special if used correctly. Other possibilities include changing the count size, using SHADE mode, starting at a different screen position and placing the brush in a perspective angle. If you are using the new Dpnint TV, try HAM mode with transparency set at 50% or less .Change your resol u- tion or palette. Modify the center point of the screen to avoid total symmetry-.
"Semi-Automatic" Painting and Animation by Kevin Lucie The most important tools to play with are the numbers in the DIST and ANGLE boxes in the MOVE requester. Kicking in values that divide unevenly so as to produce irregular patterns across the screen works nicely in some cases.
Avoid large, opaque brushes that block out a lot of previously drawn brush areas. Use small, thin brushes or shapes that contain a lot of holes to allow the viewer to see the subtle patterns that your poor Amiga has worked so hard to display. Often a brush will give more "action" if you set the handle a fen7 inches away from thecenter. It'sa good idea to test the action of the brush with the PREVIEW button.
If you have a horrendously large number of frames set, try testing it with fewer frames temporarily to save time. When you're happy, reset the number and DRAW.
Two common problems surface when testing. The first is that the brush can spend much of its drawing life off-screen if the coordinates are set incorrectly. The second has to do with ihe brush getting too "close to you," causing big jaggies and occluding areas of the painting, You canoften fix this by adding some positive Y DISTance to push the brush away a little.
Animbrushes open up another interesting realm of possibilities as well. They will continually change as they are stamped down, making them a natural tool for Semi-Automatic painting. Construct or load your animbrush first, then set it into action with the move requester.
If you have followed so far, you can see that the basic reason that S-A painting works is that the Amiga is stamping a brush and shifting hundreds of times on a single frame using animation tools, creating patterns that would be almost impossible to draw otherwise. Once you understand that, it's time to move on to Semi-Automatic animation.
¦Follow the above steps for S-A painting, but add one more simple step. Set a low number of animation frames, such as 10-30. Set your COUNT number (from MOVE) to a high number, maybe 300 or more. This will cause the brush to "overlap" the frames. As before, you may experiment with any positive or negative numbers in the DIST and ANGLE boxes, testing with PREVIEW. S-A Animations often give ihe illusion of a much greater number of frames than they actually have,due to the eye following the brush throughout the overlapping.
Though I've spent over a year developing and experimenting with Semi- Automatic painting and animation techniques, it's probably just the tip of the iceberg. It does not take the place of true drawing skill or "Real Art," but it does feature elements of creative control and unpredictable accident. It will be interesting to see what others with different methods will do to further develop this strange technique.
Two common problems surface when testing the brushes. First, the brush can spend much of its life off-screen if the coordinates are set incorrectly. Second, if the brush gets "too close" to you, it will cause large jaggies".
Mirrored Ghost Images Now that you are a Semi- Automatic Expert, are vou ready forone more interesting technique? This will work for any IFF picture, but it's especially effective on cycled S-A paintings. It gives your painting the illusion of transparency and more colors. Once you have your picture saved, press "j" for a spare screen.
Clear it to white. Select the background color that was on your picture screen as your current paint color. Using magnify, stamp down two pixels catty-cornered from each other, like two little stairsteps. Pick up this tiny 2x2 checkerboard, being careful to not pick up anything else. Click on the Filltooi with your right mouse button to bring up its requester. Click FROM BRUSH and you should see the pattern window fill with yourchecker- board texture. Now swap back to your picture screen and select the Filled Rectangle tool.
Starting at the top left corner, drag your lacey pattern all the way across to the bottom right of the screen. The screen will dim as the checkerboardfills it. Now pick up the whole screen as a brush ("Pull harder, Agnus!"), and press "x" to flip it horizontally. Stamp it down to fill in the background checks, and hit Tab to cycle. Voila! Now do you believe in ghosts?

P. O. Box 2140 Fail River, MA 02722-0869 Screen Photography An
inexpensive method of sharing computer graphics by Patricia E.
Murphy picture is worth a thousand words, but only if it is
pleasant to look at, has a meaningful message, and has graphic
resol ution fine enough to complement the subject matter.
Screen photography offers all of the above so that you may
share your latest masterpieces with the world in hardcopy
Amiga users have been producing high quality graphics for some time, but have not been able to display their talents in hardcopy form without going to the type of printers, copying techniques, or devices that are usually not found in the average homes. Most of our printers just do not do justice to our creations.
Many of us have been waiting for high quality affordable printers, but prices are still pretty high. Instead of storing your favorite graphics on d isks waiting for a ti me when you can share them with others, try photographing them.
This might be the time to get out your personal camera and try shooting a few frames. Photographing the screen allows the user to repro- d uce images at a resolution equal to WYSIWYG (What you see is what you get). With some trial and errorand a few tips, anyone can be sharing theirbest computer creations in very little time.
Above and Top: Screens created and shot by the author. The pictures are ol a meadow lark and a swan.
To get started, you will need a camera with interchangeable lenses. You can get very good results from using a 35mm single lens reflex camera and a tripod or firm support. A fixed lens camera will work, but lenses around 50mm to 100mm work best. You will want a lens that can focus at your chosen distance from the screen. This usually isn't a problem as most general mid-range lenses focus at about twenty inches and beyond. Of course, some special close-up lenses focus up to just a few inches. The object is to be able to eliminate the monitor borders, unless you want them in your picture. You
must also remember that some cameras usually show a little more subject matter in the picture than what shows through the viewfinder, so you will want to allow for that by closing in on your subject a tittle tighter.
A Next, you will want a camera that has manual controls of aperature and shutter speeds. An automatic camera will not work well unless it has manual overrides, because you will need to keep your aperture setting at around f-5.6 and your shutter speed around 1 8 of a second. The slow shutter speed is important because the screen is in constant rotation of the three primary screen colors. All three of the rotations must be captured in the picture to get the proper color and contrast.
These rotative passes are going on all of the time and even though the human eye cannot separate them, the camera can. A shutterspeed of 1 8 of a second seems to work with just about any monitor, but you can experiment with any of the variables. Some cameras are very successful with faster speeds.
The film choice is just as important as the proceeding information. If you want black and white pictures, you should probably start out with a film like Kodak Technical Pan film, by sive movement. If you don't have a cable release, you may use your camera's automatic timer, if it has one. This works fine with still frames and helps to prevent accidental movement when depressing the shutter release by- hand.
You might try using an ultra-violet iight (UVJ filter in some situations, but you will have to experiment. If you are really into photography, youcanexperiment with many types of special effect filters. Double exposures always offer interesting effects. Whenever you try to photograph graphics from white paper, you must use the (UV) filter or the results will have a bluish cast with certain slide films.
Most of the graphics that you wan t to take will probably be stills, so movement probably won't be a problem. If you want to take a picture of a screen that may move, you could try to pause it or try using print to screen to stop it. There are certain computer programs availablewhich will freeze or grab whatever is want to find a place that will follow your instructions and will give you results to your satisfaction. There are many professional labs that develop film according to your specifications or crop pictures if necessary for you.
There are several mail order labs that are also good, but you will have to call them first if you are not familiar with their work. Most one- hour labs usualiy must send out slide film, and black and white film, so you will not gain time with them. If you work with the same lab most of the time, then you most likely will pay only for the work that they develop to your satisfaction.
Computers can produce some very interesting results with several of the graphic programs that are available today. Now you can share some of your best creations by photographing them from the screen and sharing them with others in a form that has acceptable resolution and appeal. No longer do vou have to downgrade your efforts by trying to reproThe room should be as dark as possible with no light coming through windows or under doors. You must try to eliminate all reflections off the screen for best results.
Eastman Kodak, Inc. The film can be set at a variable of ASA ratings, so you must inform the lab processors which ASA rating you used, and tell them to develop for maximum contrast. The best setting for this film to get thebest contrast would be ASA 20(1. If you want color reproductions, your best choice would be a slide film like Kodak's Ektachrome 100 or 200.
You may also use the slides to create prints if you wish. Slide film is more precise and you have maximum control over your results, which is not the case with print film.
Lighting, as in all photographic work, is critical. In thiscase, it is fairly simple. The room should be as dark as possible with no tight coming through windows or under doors, etc. You must trv to eliminate all reflections off the screen for the best results. A tripod or sturdy support will be needed to hold the camera still.
Not too many photographers can hold a camera still at 1 8 of a second. The average handheld camera speed for a steady hand is about 1 30 to 1 60 at best. If you have a cable release for the camera's shutter, use it to avoid exceson the screen so that you may save it. Taking pictures from the TV is much more difficult, since the screen refreshes 60 tunes per second.
You should try a shutter speed up to 1 30 of a second for TV, but you will have to experiment to avoid blurring.
One of the best ways to insure better pictures, is to bracket your settings. This means that you must take more than one picture of each subject with different exposures. As an example, you might take one picture at an aperture of f-5.6 and a shutter speed of 1 8 of a second, and then bracket your aperture one or two settings each way at f-2 and f-4 at one end, and f-8 and f-11 on the other end. You might also want to bracket the shutter speeds by bracketing in the same fashion. There are many possible combinations and after you become familiar with the technique and take several pictures
under the same conditions, you will learn approximately what works for you, Because you will want to give explicit instructions to the processing lab, you will duce them with a dot matrix printer. Although some dot matrix printers duplicate graphics fairly well, they never seem to do the picture justice. Photographing screen images will give you a photographic print or slide that can be utilized in many ways. Slide presentations, video applications, or printed media can then be made from your reproductions. Screen photography offers one more avenue for creativity which m ight pro ve to be a
lot of fun and can be very rewarding,

P. O. Box 2140 Fall River, MA 02722-0869 AMIGADOS
l. cli directory by Keith Cameron
1. IN RECENT ISSUES of Amazing Computing, I have discussed
various concepts of using the CLI (or Shell), ranging from the
value of using the CLI rather than Workbench, to how to use
the RAM disk more efficiently. Now that Christmas is over and
there are some new Amiga owners out there, perhaps it would be
useful to back up a bit and look at some basic principles of
using the CLI.
As 1 have indicated in recent articles, 1 strongly feel that every Amiga user should at least be familiar with the CLI. In the November issue, 1 outlined its advantages over Workbench. This is in no way intended to demean Workbench, though, for it is easy and fun to use that intuitive environment. Some newcomers, however, have a tendency to rely only on Workbench, and therein lies the problem. If you use only Workbench, you are not using your Amiga completely.
Ad mifted ly, the CLI is more difficult to use than Workbench: there is more information you must remember, you must type in commands rather than use the mouse,and the environment is not as attractive. The extra effort needed to use the CLI, though, is well rewarded with extra power and other benefits. This is probably a good time to point out that CLI, Shell, and AmigaDOS are virtually the same, so don't let the terminology fool you. AmigaDOS refers to the actual language used to communicate with the computer, whileCLl and Shell are two environments that allow you to use AmigaDOS.
To start, boot your Amiga using your Workbench disk as you normally do. As always, be sure that you are working with a backup copy and not the original copy of Workbench. Once it is booted, open your Workbench by clicking on the disk icon. From here, double-click on the System directory. Next, double-click on the CLI icon. You now have the CLI window open and are ready to work. Resize the window so that you will have the full screen to work with.
Empty (dir) Let's examine what we have done thus far. To open the CL!
Window, we first had to open the Workbench disk, then the System directory, and finally click on the CLI program icon. It is impossible to go directly to tire CLI icon from the disk icon when using Workbench, for there is a set route that you must follow to get there. This route is called a path, or pathway, and pathways are extremely important in AmigaDOS. In fact, for people with little or no computer experience, this is a complicated concept to understand, but a very necessary one.
When using Workbench, we better understand that the computer can only work with programs that we are able to see on the screen. W e have more difficulty understanding this when the icons are gone, though.
Let's compare what we have done on the Workbench to this point with how it would be done via the CLL If we were operating from the CL! Already (you can, by the way, reconfigure your Workbench disk to boot to the CLI rather than to the Workbench), we would start by opening the d isk to i ts root director}', which is the same thing as you see when you first open the Workbench disk. To do so, type DIR DFO: RETURN at the 1 , which is called a prompt, and you will get a listing of all files and directories at the root directory of the Workbench. Here is that listing for version 1.2: Trashcan
(dir) c (dir) Demos (dir) System, (dir) 1 (dir) devs (dir) s (dir) t (dir) fonts (dir) libs (dir) Clock Demos.info Empty.info Preferences System.info UtilKies,info Trashcan.i nfo Clock.info Disk.info Expansion.info Preferences.info The first thing that might strike you is how much more is exposed from tire Cli than from Workbench. As I have expressed before, this is a major reason for using the CLI more frequently. There are many programs that are just not available from Workbench. Notice also that ail directories are listed first (with "dir" written to their right in parenthesis), followed
then by files. In AmigaDOS, you have two types of instruments: directories and files. If you use Workbench frequently, you might call directories "drawers" due to the icons. If you look closely enough, you will notice that the directories that appear as icons Now go back to your Workbench and you will notice that the icon for Empty' is gone; however, tire directory itself is still there, and files can still be stored in it, but only if you use the Cli. By not using these icons, you can save a little space on your disks and a little RAM in your memory. For A500 owners with only 512 K of RAM,
this can be useful.
Also, on a disk with 20 icons, you can create enough room for several small programs simply by deleting the icons. If you want the Empty icon back, simply copy one of the other drawer icons and rename it Empty .info. You can do so by using only one command: COPY DFO:SYSTEM.INFO TO DFO:EMPTY.INFO RETURN Utilities (dir) Expansion (dir) . Info Next time tlrat you look at the root level directory from Workbench, you will see that the icon is once again there. To return to our project, we next need to enter the System directory'. From Workbench, we simply double-clicked on the System icon. This
forced us to follow a path. In AmigaDOS, we must follow the same path, but we do it by typing rather than by clicking. So, this time, ty'pe DiR DFO:SYSTEM RETURNS and you get the following listing; . Info DiskCopy The extra effort needed to use the CLI is well rewarded with extra power and other benefits.

Since AmigaDOS does not distinguish between upper- or lower-case letters, this distinction is merely for the convenience of users.
You will also notice thatal! Of the directories or files thatare visible in the root directory of Workbench appear twice in AmigaDOS. The first time, the instrument appears either as a directory (with "dir" written beside it) or as a file (with nothing written beside it). The second time each instrument is written, it ends with ".info". This second instrument, for example "Clock.info", is actually a separate file, which is the icon itself. If you were to get a reading of the size of these files, you would see that most of them are about 1,000 bytes. In order to be visible from Workbench, a
file or directory must have a separate .info file, if you want to experiment, delete the .info file from one of the directories, such as the Empty directory. You can do so by typing Once again, you will notice ail of the ".info" files, which indicate that every file in this directory is accessible from W'orkbench, for each one has an icon. If you were to run one of these programs from AmigaDOS, you would have to type the entire pathway: RUN DFO:SYSTEM FILENAME iRETURNi FILENAME in this example, of course, can represent any of the programs. If you want to run one, I would suggest IconEd. The
slash is used in AmigaDOS to separate directories and files, or directories and other directories. The colon (:) is used to separate a disk (sometimes calleda volume or drive) from directories and files. These punctuation marks are extremely important in pathways, so be sure to include them.

If you had used the CD command (discussed in the December issue), you could make the System directory your current directory by typing CD DF0:SYSTEM RETURN Then you would only need to type RUN FILENAME RETURN to run the program. The RUN command, bv the way, should be used when running programs to allow for true multitasking. Although programs can he run simply by typing their name, it is advisable to use RUN, as this returns control to the CLI. To study pathways further, examine the diagram of a partial Workbench disk. (FIG 1.)
Tire purpose of the diagram is to help you visualize pathways. If your current directory is the root directory and you want to use the calculator, you have to tell thecomputer exactly where the program is; that is, in the Utilities directory. Otherwise, it will simply search through the current directory for the program. Why can't AmigaDOS look through all of the directories? Weil, it can, with some adjustments on your part; but, as is, you must type in the pathway. One advantage of this is that you can have files with identical names in separate directories. For example, you could have two
calculators, one in the Utilities directory and another in the System directory. The one in the Utilities directory is rather basic, hut the one you install in the System directory can be one that does various advanced operations. Since both have the same name, which does AmigaDOS run? That’s the good thing about pathways. This advantage really becomes clear when more than one person is using a single computer. If each has a directory, they can use the same names unknowingly without causing problems, such as overwriting each other's files.
Does the Workbench seem easier and faster? Let's see. On my older Amiga, to open the disk, then the System directory, and finally start IconEd requires about 20 seconds. I arrived at this time very unscientifically by starting a stop watch when I first double-clicked on the Workbench icon and not stopping it until the green drive light on my computer went off after opening IconEd. !n contrast to this,! Only needed about 8 seconds to start the same program from the CLI using the commands discussed above. Time is saved by not having to wait for windows to open before proceeding. Using Workbench,
you would have to wait for the Workbench disk to open before opening the System window; then you would have to wait for that window to open before clicking on the IconEd icon. Now, before you Workbench advocates start sending in those cards and letters of protest, please rememberthat this is in no way intended to be a scienti tic test. 1 am a fairly fast typist and can type the necessary command line rather quickly, but other people may require the entire 8 seconds just to type in the command line. However, this does demonstrate to some degree an instance when AmigaDOS can be preferable. Yes,
you have to know the pathway prior to running the program, and you have to remember the specific names of files to save time. But, once again, you don't have to wait for the window of a directory to fully open before you open a file or another directory in it.
Let's cover one more item. Go bock and look at the files in the System directory. Do you notice how two or more words often seem to be shortened and put together to form one word? Have you considered why this happens?
In AmigaDOS, it is more convenient to use single word names for items. Let's do an experiment to demonstrate this. Make the System directory your current directory by executing the following command: CD Dr O: SYSTEM RETUF_N Once you have done this, rename IconEd to its real full name, which is "Icon Edi tor". Be sure to leave the space in between the words.
RENAME ICONED ICON EDITOR cRETURN Figure 1: A diagram of a partial Workbench disk.
- System (dir)
- s (dir) Disk fonts (dir) libs (dir) Calculator
- Utilities (dir) Notepad
- Expansion (dir) The drive will spin momentarily and then an
error message will pop up below the command saying something
like "Rename: Bad positional argument". Now what does that
mean? Before answering, let's try something else. Go to your
Workbench, open the System directory, and try renaming the same
file "Icon Editor” by using the menu bar of Workbench. Now what
No problem for Workbench, right? That's because Workbench is programmed to handle spacing between names, unlike the CL1. There is a way to get around this on the CLI, though, and that is by using quotation marks.
Go back to your CLI window now and type the following: RENAME ICON EDITOR ICONED i?ETUP.N You should get the same error message you had a moment ago ("Rename: Bad positional argument"). Now try the same command using quotation marks around the name that uses more than one word.
RENAME "ICON EDITOR' ICONED RETURNS This time the drive spins, then the prompt on the next line appears, indicating thatthe command has been successfully executed, if you get a listing of the directory, though, you will see a slight problem. Type DIR RETuRM and all of the files in the directory will appear. You will see that "IconEd" is there, but "Icon Editor.info" is also there. In fact, if you go back to Workbench and look in the System directory, you will see the Icon Editor icon still present. Click on it to see what happens.
The screen should flash, indicating that the file can not be opened.
When you rename something from Workbench, both the file (or directory) and its icon are renamed. However, from AmigaDOS, only the file or directory is renamed. So, from AmigaDOS, you will need to type RENAME "ICON EDITOR,INFO' ICONED.INFO RETURN in order to rename the icon to make it match its file. This time, everything should appear in order.
For the convenience of all users, most programs will have names without spaces. To indicate where one word ends and another begins, several methods are used. On the Workbench disk, for example, a capital letter indicates where another word begins, such as in IconEd (Icon Editor) or InitPrinter (initialize Printer). Some people use the underline key from the keyboard to indicate spacing, as in Icon_Editor or Initialize_Printer. This allows the full name to be used for clarity.
Other people use a hyphen, for example Icon-Editor or Initialize* Printer. Of course, slashes ( ) and colons (:) cannot be used, as AmigaDOS interprets these as symbols to separate volumes, directories, and files.
To be able to use the CLI well, it is imperative that you understand pathways, the use of quotation marks to overcome spacing, and that .info files indicate icons. In my next article, we will alter the startup- sequence of jour Workbench disk and customize it specifically for you.

MULTIMEDIA Those of you who have seen the Star Trek Trivia PD game may have wondered how difficult it would be to create a program like that.
STT combines a polished look and a solid feel which is not often found in a PD game. No one who plays Star Trek Trivia can doubt that hours of effort went into its creation. What may not be quite so obvious is that most of those hours were spent compiling the thousands of questions and answers which make STT so addicting and not on the mechanics of the game itself. If you are familiar with any of the popular authoring systems, you can lay out the skeleton of a program like this in a matter of hours. The version of Star Trek Trivia which I saw was done with The Director, but AmigaVision, CanDo,
HyperBook, or Foundation might have done just as well.
The program is composed of three parts: graphics, logic and database. All of these parts play an important role in the final product as we shall see.
The graphics for this program are not complicated. All that is needed is an interface screen, someplace to paste the numbers and scores.
GRAPHICS: the first thing a program user sees. Most u sers ma ke some basic decisons about a program based on how it looks. Graphics must be well done and appropriate to the task.
PROGRAM LOGIC: the glue that holds everything together. The program must execute in ways that are both predictable and repeatable.
DATA BASE: a program like Star Trek Trivia, depends on questions and answers which are organized into data bases and accessed from the program.
During the remainder of this article, we will look at graphics, organization, and logic.
We will examine the data base in a later article.
The program examples I will use are based on Amiga Vision flows and The Director scripts because I feel that these programs do a better job of following traditional programming structure. If you use CanDo, Foundation or Hyperbook, the principals remain the same even though some of the mechanics are different.
PROGRAMS THAT WORK PART 1: GRAPHICS AND LOGIC by Dave Svitler Let's begin by looking at a simple quiz program which manipulates numbers. This program is part of the addition module from a larger program i call "MathDrill” which presents the user with a problem and records the answer. The program judges right or wrong answers and keeps overall scores.
The graphics for this program are not complicated. All we really need is an interface screen someplace to paste the numbers and the scores but larger programs require more screens and this leads to considerations of program execution and memory. In most cases, your program will execute better with imported painted IFF screens from a paint program rather than the internal graphics tools provided by the authoring system. This is because your program lias to re-draw the screen as it steps through its instructions. The delay while the computer refreshes an internally created graphic piece by
piece is distracting and irritating.
If your program contains a lot of graphic screens, size quickly becomes an issue. Your programs run leaner and faster when you use brushes to change existing screens rather than providing whole new ones.
Lastly, consider the way your program will look to the first time user. Lo-res "quick & dirty" graphic screens are OK during development, but the final version should have well executed high or medium resolution screens.
The logic part of our program will be fairly simple. You can do it if you are familiar with three concepts: variables, "IF" sta tements, and loops.
Understand ing var iobles is crucial to most programs. A variable is just a symbol whose meaning changes. The "x," "y," and "z" we encountered in high school math are variables.
You can continually redefine "x" or "y" and combine them if you want to get a new "z."
Variables are used to help con trnl the program as well as to capture and save user responses.
Wewill see just how powerful this concept can be, especially combined with "LF" statements.
"IF" statements are the conduit which makes the logic flow. Think of a menu which offers four choices. When the user selects an option, you have to translate this into action.
You do this with an "IF" statement which says: "If box number 1 is clicked, do this." In Amiga Vision, you pull an "IF-THEN" or "1F-ELSE" icon onto the screen and type a statement into it("response()==l"). Director scripts usea line of text which begins with "IF" and contains a "THEN" somewhere. Three actions are possible with an "IF-THEN” statement: you can start a series of actions immediately, vou can send the user someplace else in the program, or you can use a variable to record the choice for future use.
Finally, we need to deal with two somewhat related cuncepts, the LOOP and the GOTO. You can lock out unwanted actions and force your program to do repetitive tasks though use of a loop. When a program encounters a loop instruction, it executes the instructions within that loop until something allows it to move on. You can even "nest" loops within loops. I said that "GOTO" statements are somewhat related. This is because you can use a GOTO statement to return to an earlier part of the program, creating a loop. Be careful with GOTO's, however, lest you wind up with a program so Strewn with
quick fixes that it looks like (and exectutes like) a pla te of spagetti.
Now let's go ahead and create our program. To begin with, we will not ask for user input. We will just construct a program which can think up problems and answer them. To make things more interesting, we will introduce an element of error and have the program keep track of those errors when they occur.
Before we can go very far, we need some variables. We want one for score and one for the number of questions answered (so that we can figure percentage). We want the questions to have some variety, so we will have the computer choose numbers with its random number generator. Thinking of the familiar formula of x + y=z, we will have the computer choose x and y at random and then have it calculate z. We will also create a variable called "a" to represent the useranswerand a variable which we will call "err" which we will use to cause our program to make mistakes once in awhile. We will begin by
establishing a pa i nted screen with windows on it for all of the various numbers to be displayed, and immediately following that, we will begin our variable statements, A Director script might begin like this: LOAD 1, "DH1:Math Fix Input1" :rem loads picture into memory PAUSEMODE 0 LOADFONT 1,12, "rubv.font" :rem loads font num=0 :rem ft of questions variable score=0 : reiti score variable top: :rem this begins the program loop a=0 :rem variable tor "user answer" pct=Q :ram % of correct answers err- ?7 random number x=?99 tion of x y=?99 tion of y z=x+y :rem :rem makes error a :rem random
selec- :rem random selec- establishes z (NOTE-1’: rem" is used to separate remarks from the program) We will do everything from this point on by manipulating those variables. Notice that some of the variables are stated before the program loop actually begins (at the label " top:") and some are stated afterwards. Those variables which must be reset each time the program loops must be introduced after tire loop begins, while those variables which should not be reset (such as "num" and "score") must be introduced before the top of tine loop. Take a look at the sample of Amigavision code from
"MathDrills". The Loop Icon near the beginning of the sample forces the code which fol- The program is composed of three parts: graphics, logic and data base.
Lows to come back and start fresh over and over agai n. I n tine Di rector script, the loop is set up byplacing a "goto" instruction which points back to the " top:" label at thebeginning of the loop. Instructions which occur before " top" will not be refreshed when the program loops but those which occur after that point will. The score variable is incremented by an "IF" statement ("IF a = z") followed by the instruction "score=score+l ."The "num" variable which is counting the number of questions asked, is incremented by an instruction which says "num=num+l" every time the program be
gins a new loop.
Since we do not want to answer the same question for twenty or thirty times, we place the instructions "x=?99" and "y=?99” inside of the loop. That way, every time the loop cycles, a nevv random value between zero and 99 is chosen for both "x" and "y."
Look at the scrap of Amiga Vision code again. The "Variables" icon (the block with x and y on it) appears both before and after the loop icon. If you double click on these variables icons, you will find all of the same variable statements there which we set up in the first few lines of code in the Director script. The one difference is that the script looks complicated because a series of "IF" statements has been introduced to allow the user to choose one, two three or four column addition.
At the end of the program, we add an "!F- ELSE” which compares the variable "z" (the correct a nswer) with " a" (user answer). If a=z, one thing happens, while something entirely different happens if a and z are not equal.
Finally, a series of "Wait-Mouse" icons with 1, 2 or 3 second delays will keep our program from running so fast that humans cannot keep up with it. (The same thing was done in the Director script by adding "PAUSE" statements.)
Once we have our little program up and calculating, it is a fairly simple matter to get it accept user input and place it in tire "answer" box on the screen instead of the computer answer. In Director scripts, this is done with an "INPUT" statement. In Amiga Vision, this is done by selecting a "form" icon from the Data menu. Through the "object editor", the form icon allows you to establish data input fields as well as text and variable fields and place them anywhere you may need them on the screen.
Remember the "a" variable? We can now use that to collect the user answer and compare that to the value of "z" (z=x+v). If a is equal to z, the user's answer is correct. If a is not equal to z, the answer is incorrect.
Now we have created two simple programs, one of which puts the user through simple math drills and one of which allows the computer to be both the teacher and the student. Can those two programs be combined in some way? You could do it through interlocking menus or by having the comp uter revert to the self testing "demo" anytime no student is using it. Next month, we will use a data base to expand this simple question and answer session into anything from a technical training program to a mammoth trivia game.

P. O. Box 2140 Fall River, MA 02722-0369 |These statement!; and
projections presented in "Roomers" are rumors in the purest
sense. The hits of information are gathered bp a third-party
source from whispers inside the industry. At press time, these
rumors remain unconfirmed and are printed for entertainment
Accordingly, the staff and flssocinfes of Amazing Computing cannot be held responsible for the reports made in this column.] R O O ME R S by The Bandito The Wacky World of Commodore Here's some good news about Arnigas: Commodore has announced that unit sales of Amiga computers reached the three million mark in November 1991. This milestone was reached twelve months after Amiga sales hit the 2,000,000 mark in November 1990.
In case you weren't around, Amigas started shipping in September of 1985. It took three and a half years before sales hit the one million mark in March 1989. Then the two million mark was reached one and one-half years later in November 1990, So obviously, the sales picture is improving. Of course, the Bandito hears that Commodore threw in sales of CDTV to add up to that three million mark, but don't worry; CDTV sales are a very, very small portion of the total the Bandito hears as of November, only about 30,000 units. Equally noteworthy, of course, most of those Amiga sales were in Europe,
not in America.
It's very interesting how Commodore's press release describes the Amiga product line; here's the quote: "The Amiga product line is comprised of the Amiga 500 and 500+ targeted at the home computing market and the Amiga 2000 and 3000 series focused on the professional video production, desktop publishing, and multimedia office productivity markets." The "multimedia office productivity" market? The Bandito would like to know the names of the pharmaceuticals being used by Commodore marketing; they sound pretty potent. Such vivid hallucinations they're having these days.
Desktop publishing? Is that really a major source of Amiga sales? Who are they kidding, anyway? These marketing whizzes arc finally getting around to giving up on the UNIX market. Talk about being in tune with your marketplace. Can we sell these marketing people to Atari? Just asking, mind you.
Tropic of Amiga Here's a fun factoid for you: Commodore's official headquarters are located in Nassau, Bahamas though the address listed is really an office of Ernst & Young, their accountants. Why would an international company whose products are sold in Europe and America, and whose chairman lives in Canada, have its official HQ in the Bahamas? Can you say ''tax dodge" three times fast? Sure vou can. But seriously, folks, the Bahamas are a great place for official headquarters and annual meetings. You don't have to worry about being overwhelmed by hordes of Commodore stockholders asking
inconvenient questions; if they hold Commodore stock, they certainly don't have the money to head to the Bahamas. Nor will you be smothered under masses of wealthy Amiga developers eager to send their staff to the Bahamas, trying to get rid of some of the massive profits thev've made selling Amiga add-on products. No, the Bahamas are a quiet, restful place lor annual meetings... at least, usually. But 1991 was different.
Commodore's annual meeting was attended by less than a dozen shareholders, even though it was held at a very posh Bahamian resort. The Bandito would like to salute a bold Amiga fan by the name of Dan Hess, who flew from Ohio to the Bahamas to attend the meeting. Hess put his question directly: why isn't Commodore advertising the Amiga more in the U.S.? At least Irving Gould, Commodore's chairman, gave a direct answer: they've tried it before with no success. The Amiga isn't available at enough places to make a difference in sales by advertising. That is, advertising creates demand, but then
people have no place to buy it. (Compare the density of Amiga dealers to the density of IBM dealers or Mac dealers.) Sad, but true.
And the financial picture in the North American market isn't rosy. Commodore reaped 85 percent of its fiscal 1991 sales of SI .04 billion in Europe. Meanwhile, Commodore's losses in the United States and Canada grew to $ 24.7 million on sales that plummeted by one-third to $ 110.1 million in the fiscal year that ended June 30. Compare that to a loss of S17.7 million on sales of S163.5 million the year before.
Meanwhile, the European picture looks very good. International Data Corp., a market research firm, says Commodore controls 12.4 percent of the personal- computer market in Europe, behind IBM's
12. 7 percent, Olivetti with 6.2 percent, Apple's Macintosh
computer with 5.2 percent and Compaq with 4.6 percent.
Revenues from Commodore’s line of PC clones were up 14 percent; C-64 sales were up 4 percent as the Bandito told you before, those cheap little computers are doing well in Eastern Europe).
But despite megabucks spent in TV and magazine ads over the past few years, the North American operation continues to lose money. Commodore's got lots of excuses handy; the economy's been bad, there's not enough dealers, or people think Commodore only makes game machines, And various fixes have been tried, usually dumping the current guy in charge and cleaning out the old staff. The latest casualty, of course, was Harry Copperman, who got the boot in January to be replaced with Jim Dionne from the Canadian branch of CBM. Since then, most of Copperman's old cronies have been axed and things
have been reshuffled yet again.
The whole thing puts the Bandito in mind of the old joke: The new company executive finds three envelopes in his desk, left by the last CEO on his way out. The envelopes are sealed, labeled "Open in case of emergency", and numbered 1,2 and 3. Of course, the company's in trouble, so the new CEO opens the first envelope. It says "Blame your predecessor." So he does, and everything's all right for a while. But then things are worse than ever, so he opens the second envelope. It says, "Blame your vice- presidents." That works for a while, but then the company is really heading for the skids.
Jn desperation, the CEO opens the third envelope. It reads: "Prepare three envelopes...". Commodore, in the course of slashing expenses to compensate for falling sales, has laid off about 100 people and shifted most manufacturing and assembly out of West Chester to other Commodore plants. Some of the more cynical observers might wonder whether Commodore is planning to just give up on the North American market. Seems unlikely, sez the Bandito; even Could admits the U.S. market is too big to ignore.
One issue brought up at the meeting was the rather touchy one of executive compensation;shareholders complained about Ali's and Gould's salaries. Gould earned $ 1.75 million, while Ali earned S2.4 million for 1991. Gould in 1989 was granted options on 350,000 shares of stock, while Ali was given 120,000 shares in the last fiscal year atop 300,000 options given previously.
As a point of comparison, John Akers, chairman of IBM (50 times Commodore's size), made $ 2 million in salary in 1990. Say, maybe that’s what's happening to Commodore's marketing budget... So what is Commodore going to do about the whole situation? Nothing, for now.
They’re pinning their hopes on the new generation of Amigas, which are due to arrive in 1993.
Commodore president Mehdi Ali dropped some broad hints, but he wouldn't give any details. Once the new Amigas come out, you can expect Commodore to try all over again to sell Amigas. Here's hoping they ha ve more success in the U.S. of A. CDTV Update Well, Christmas has come and gone, and CDTV did not conquer the world. Nor did CD-I; the Bandito supposes that consumers are unwilling to drop $ 800 on a new toy of dubious value and uncertain software, which at this point characterizes both machines. So what happens now? If you look at Commodore's past performance with hardware, you'd expect that
they'd drop CDTV like a hot potato, dumping it into the dustbin of history along with the Plus 4. But the Bandito's sources indicate that Commodore believes in the future of CD-ROM, so they're going to stick with it a while longer.
Will Nolan Bushnell stick around, too?
The answer is no; Nolan has already left AMIGAbly for greener pastures, starting yet another new business or two. Commodore still has a lot of resources committed to CDTV, though. But let's look at what the competition is planning.
Although CD-I sales weren't much this last Christmas, CD-I distribution blew past CDTV. You can find CD-I everywhere, whereas you really have to hunt to dig up CDTV on sale once you leave the Amiga dealership. Now the Bandito hears that Philips is trying to convince Blockbuster Video to carry CD-I titles and players for sale and rental. According the Bandito's sources.
Philips has invested S100 million or so in Blockbuster, and sort of expects Blockbuster to do them a favor in return. So it looks like Philips will have the best possible distribution for CD-I players and titles.
Meanwhile, other companies have finally indicated that they will be producing CD-I players. At a recent CD-I conference, Yamaha showed a CD-I player with MIDI capability, Pioneer showed off a CD-I player that can play laserdiscs, Sony displayed a portable CD-I player prototype, and Samsung and Goldstar also announced players in the works. You might see these widgets in the stores by Christmas... or you might not. Prototypes don't mean production, and the Bandito suspects that these companies may be a little wary of committing a lot of resources to CD-I before it's a proven success. Anyway,
if these companies do enter the market, CD-E prices are likely to drop. Expected prices are $ 500-5600 by Christmas 1992, and about S200 in four to five years.
CD-I backers are hoping that the upcoming MPEG support, supposed to be available sometime in 1992 (hah!), will make a big difference. This will take the form of some additional hardware in CD-I machines, causing a boost in price of some unknown amount. MPEG is a standard for compressing video, giving very high compression ratios. Some CD-I stalwarts believe that MPEG capability can make CD-I into a video playback device. The Bandito has to laugh at this. First of all, MPEG video quality looks like VHS tape re-recorded about four times in other words, pretty poor. Second, why would you spend
S1000 on a CD-I player with MPEG to play cheesy video with no slow-mo or freeze frame (MPEG compression won't allow this) when you could get a laser disk player for $ 300 and enjoy 400+ lines of resolution on inexpensive laser disks?
But it looks like CD-I is beginning to get some momentum, however glacial it may be at the moment. Philips is convinced that their sales will parallel the CD player sales curve, with exponential growth rates over the next few years. What have they been smoking over there?
Of course, the real question is: How can Commodore jump-start CDTV sales? The Bandito hears some interesting speculation coming out of West Chester, CDTV and CD-I together? Don't laugh; it could happen.
Apparently, although Commodore has demonstrated CDTV displaying PhotoCD images, PhotoCD needs Philips authorization, according to some sources. What if CDTV added CD-I capability? It would still be capable of either mode. Perhaps that would give it an added edge in both markets. The licensing fee might not be too high, but the extra hardware costs might be a bit much. The Commodore CDTV CD-I would be the only CD-I player that could turn into a real computer, and perhaps the only one with cool video capabilities (if they could get a version of the Video Toaster for it...). But the Bandito
puts the chance of Commodore adding CD-I capability to CDTV at around the same level that Commodore marketing will win an award for excellence. So the Bandito suggests positioning CDTV as the one CD-ROM machine that can be a real computer at a realistic price. Look, CDTV's big advantage over CD-I is the fact that CDTV is a usable computer.

Ing" kit for CDTV is an intelligent move on the part of Big C. The kit serves to differentiate CDTV in the marketplace from CD-I. CD- ! Doesn't take a keyboard, can't do word processing, can't do video work, can't add a hard drive or a floppy. If the price of CDTV heads a little lower, it may still do wonders in the marketplace if it is positioned as an inexpensive multimedia computer.
So save CDTV and reposition it as the perfect home computer. It’s got an enormous price advantage over its nearest competition, the MPC computers, which start at around $ 2500 and are still amazingly wimpy even for that amount of money. And CDTV can hook into a TV set. The computer connection is the weak link in CD-I armor; the CD-I box can't add a hard drive, keyboard, floppies, modems, and printers.
And get some action in the software end of CDTV. Get some real education oriented stuff. No, not Barney Bear (fun as that is for kids); what CDTV needs is Cliffs Notes on CD-ROM. The Oxford English Dictionary. Roger‘s Thesaurus, Bartlett's Quotations, The Chicago Manual of Style.
Mathematics, history7, science, languages.
Heck, how about 10,000 term papers on a CD-ROM? This is where CD-I misses the whole point. Yes, it's nice to be able to look at pictures and hear sounds. But what about when you want to do your homework? You gotta have a word processor and a printer... and it sure would be great to have all that data handy. Imagine clip art CD-ROMs designed to help with your homework; IFF files for every' occasion.
Next we need a handheld version of CDTV, perhaps in concert with the notebook Amiga. Now there's a product that could reallv differentiate itself. Hev, Commodore, talk to Sony; those guys still haven't quite figured out what they want to do about CD- ROM and multimedia.
The Super NES CD-ROM being developed with Philips provides a disc format that's readable in CD-I players (though different software is needed).
However, the Bandito hears that Super NES sales have not been as enormous as expected; price drops were seen even before the end of the Christmas season, always a bad sign.
And NES prices dropped, too; could Nintendo finally be running a bit scared?
Genesis is hanging tough; the NEC TurboGrafX is the big loser even at new low price.

Of course, the videogame makers aren't the only ones in the CD-ROM market. The Bandito hears that Tandy is working on a low-end MPC machine a CD-ROM with a 12 Mhz 80286. Jcopers, that's slower than Commodore product development. And this blazing wonder machine is going to be running Windows, Actually, the Bandito should probably restate that, given the usual speed of Windows even on the speediest of PC clones: The Tandy machine will be "walking" Windows or maybe crawling.
Windows moves at about the pace that the FDA uses to approve drugs, and on this Tandy machine that would have been underpowered three vears ago, Windows will look like it's stuck.
Oh, and by the way, this machine has no keyboard. What it does have is an under $ 1000 list price, and it uses a TV for a monitor (so it probably works in 320 x 200 resolution with 16 colors, knowing Tandy graphics capability). Maybe this machine can rescue CDTV; it'll make CDTV look like a veritable speed demon. Tandy has a tradition of underpowered "home" computers, but this is really going too far. It's like using a VIC 20 for ray-tracing. This will be a much more tranquil home computer one that gives you plenty of time to think before anything happens. Great for slow-motion video games.
Just think; it can run a baseball simulation that would actually take longer than the real thing!
New Hardware Sightings Latest in the random Amiga universe news: Apparently, Commodore has slipped in a small change to the A3000. The Bandito hears that the latest shipments of A3000s have high-density floppy drives. If you put in a high-density disk, you can format it to
1. 76MB! No news yet on an upgrade path for current owners, nor
whether Commodore will release a stand-alone version of the
high- density floppy. (As we understand, probably not. The
high-density drives happened to be what was available for
installation, a fortuitous development for some new

Attendance was lower than expected, totaling 79,094. Buyers, sellers, retailers, merchandisers, and advertisers came from every continent to see the new and wonderful products on display from electronics giants such as Pioneer, Sony, Nintendo and Commodore yes, even Commodore.
The 1992 International Winter Consumer Electronics Show Most attendees canvassed their respective sections of the show stereo people with the stereos, appliance people with the appliances, and video people with the video. Butjustabout everyone who came upon the Commodore booth stopped, even if for a brief moment to tie shoe laces, and was exposed to CDTV at its finest.
Nestled between the "Gunfight at the Panasonic Corral" and Kodak's PhotoCD was perhaps the best showing yet of CDTV and its capabilities. The Commodore booth had an abundance of CDTV units demonstrating all the already-old favorites and some of the newest CDTV titles on the market. Along with the titles came new hardware applications for the CDTV unit. A kiosk with interactive CDTV software, video editing systems, karaoke to name a few.
SHOW COVERAGE Two items which made the Winter CES showing of CDTV unique were a special ad and a terrific presentation. Commodore ran a full-page ad in several of the daily show guides which directly compared CDTV' to Phillip's CD-I. Incidentally, CES show guides are pub- 1 ished da i Iv by more than one agency, amounting to several different show guides each day.
The "Can vs. Cannot" comparison drew much needed attention to the Commodore product.
Commodore's other marketing breakthrough was a giant video wall that displayed a continuously running demonstration of CDTV. Every 20 minutes or so, a Commodore spokesperson would join forces with the giant screen and give a live demonstration and explanation of CDTV's features. The live demonstration drew a sizable crowd each time, much more than any other video wall in the show with some notable exceptions: video wall theatre seating combinations, video wall glamorous model combinations, and the Nintendo Pavilion.
Commodore s booth was packed with curious people wanting to know more about CDTV.
The great attention given to CDTV brought people into the Commodore booth, where one could see other great Commodore products as well as meet with Amiga-related companies and see demonstrations of other products available for the Amiga and CDTV.
Show Overall If you are into electronic gadgets, the Winter CES was the place to be. Everything from high-tech alarm systems to Zenith Data Systems was at this show. The big companies such as Pioneer, Sony, Hitachi, Zenith, and Panasonic went out of their way to showcase their products. There were some lessons to be learned in the marketing department. R&D has taken giant leaps forward with product creation. Product design and packaging showed some interesting new looks.
Wide-screen televisions and powerful stereo sound systems teamed up to create "Home Theatre.'' There were especially-designed reclining chairs which massaged your body after a long day's work. There were tons of video game and home entertainment titles for Nintendo, Sega, and other game systems as well as virtually every computer make on the market. There were gadgets to help you eat, sleep, drive, hear, see, speak, walk and even... well, you know. If you couldn't find it on the floor of the show, it was outdated and probably no good for you any way.
The Competition As always, the video game market was one of the more competitive secti ons .Nintendo cornered the market's share of attention with its very own pavilion housing just about everyone who has ever done an NES title. Names familiar to Amiga users, such as Psygnosis, Eiectronic Arts Distribution, Maxis, Micro Prose, Konam i, Accolade, and Ocea n kept the Amiga faith among the Game Boys. Companies who produce Amiga games did not experience competition among themselvesbut rather with the other platforms for which they develop. The Amiga titles made a fair showing. New titles
from Konami, Merit Software, The competition: CDTV vs CD-I. On the left, CD-I's titles. Phillips boasts over 30 titles tor their unit. On the right, CDTV displaying VidDISC from Merit Software. VidDISC is an interactive informational environment designed as a multiple purpose tool for use in education, training and information dispensing as in a kiosk.
Kodak s PhotoCD is an electronic photo album.
Take your favorite photographs to a Kodak Imaging Center and they will digitize them and place the pictures on CD-ROM.
Electronic Arts, and MicroProse were showcased among those companies' other-platform titles.
As for competing computer platforms, PC compatibles, notebooks, and the like were abundant. Giant IBM had agood sized display.
One could say that IBM's presence was felt in the number of IBM PC's that were spread out over the entire show in other companies' booths, but then again, that is just a fact of the computer industry that Commodore and the Amiga must live with, for now.
Commodore's biggest competitor at the Winter CES was not another computer manufacturer, but a large company which specializes in home entertainment products such as stereos and television sets. This was Phillips and their CD-I. As you may know, CD-I is CDTV's greatest opponent in its rise to the top.
Phillips was not going to let Commodore forget they were around, either. CD-I was shown heavily, attached to big 26-inch monitors with full stereo sound and a unique track-ball-like controller, called the Roller Controller, which has been specially designed for use by children.
Phillips also proudly displayed their collection of CD-I titles, boasting of over 30 for their system.
Commodore Again, CDTV was the main attraction at the Commodore booth. CDTV units boasting CDXL were running interactive CDTV disks which take advantage of the accelerated CDTV format. There was also an emphasis on CD+G, which combines Compact Disc-quality sound with sharp graphics and animation.
CDTV add-ons were alsn heavily displayed . The keyboard, mouse, and floppy drive kit, now being called CDTV-Professional 151)0, demonstrated how the CDTV unit could instantly be transformed into an Amiga 500 home computer. Other new peripherals for CDTV include a trackball controller, video genlock, and 64K and 256K personal memory cards.
The trackball controller is the perfect replacement for the standard CDTV controller. The unit is designed to increase speed and control, as well as ease-of-use. It also features dual joystick connectors which can accommodate almost any joystick.
The genlock synchronizes visuals from CDTV applications with video or live television broadcast and allows the combined signal to be record ed to video tape. The card, in effect, turns the CDTV unit into a personal video editing system.
Other new goodies from Commodore include a CD-ROM drive for the Amiga 500, the A592, which was previously termed the cun CDTV Can they? In this agressive ad campaign comparing CDTV to CD-I, the Commodore ad attempts to make it clear which unit can perform the best.
A690. Also shown were several of the different A500 packages available.
Booth Buddies Commodore's booth was packed not only with CDTV and CDTV titles, but also with a host of Amiga and CDTV-oriented companies.
Psygnosis was represented by the CDTV version of Lemmings, which, by the way, is now available fortheSuperNESsystem.GVPshared booth space with demonstrations of Scab; and other products. Digital Creations demoed DCTV and the up-and-coming DCTV for CDTV.
The Software Toolworks, creators of the hottest new multi-platform educational peripheral, were there. They demonstrated The Miracle Piano Teaching St stem, a unique new device that, when used with your Amiga, teaches you how to play the piano. (Fora complete reihrtv of The Miracle Piano Tcaching System, turn to page 7 8 of this issue.)
Selectra Corporation demonstrated the Sdectra VuPort, a computer VCR interface which enables the connection of a Panasonic AG-1960 S-V HS VCR to the Am iga. The VuPort demonstration incorporated such video editing items as NewTek's Video Toaster and AmiUnk Cl software from RGB Computer & Video along with an Amiga 2000.
CDTV titles took the spotlight. Commodore now says there are approximately 80 titles available for CDTV. If you add the expansion kit, you gain instant access to over 2500 Amiga titles as well. Tiger Media, creator of Airwave Adventure: Case of the Cautious Condor, showed a new version of Condor and their latest mystery suspense title. Murder Makes At a press conference, Commodore U.S. president Jim Dionne spoke of CDTV and a promising future. Commodore sounds confident that their latest attempt to market CDTV will work.
Strange DcndfeUom. From [COM Simulations there was Sherlock Holmes Consulting Detective, a CDTV title in which you match wits with the famous Sherlock Holmes to solve three mysteries. Context Systems was showing a forthcoming release called The Tamil if Circus Video Titter. This disc allows you to customize home videos by adding scenes from the syndicated comic strip, The Family Circus. Other tities from Con text Systems i nclude A Night at the Races, a horse racing simulation and Ultimate Basket- ball, a basketball simulation. Discis Books "made reading fun" with two of their titles. The
Tale of Peter Rabbit and Scan Poems or Rotten Kids, both available on CDTV. Merit Software had their existing CDTV software and new items such as Over the Net, a professional volley-ball game and their VidDISC interactive informational environment. The VidDISC offers users the opportunity to explore interactive visual and auditory information. Merit hopes to design VidDISC multimedia applications for corporations to be used as training and informational interactive displays.
A product which could tnkend vantage of the VidDISC is DCI Marketing's Interactive Kiosk. The kiosk features a Commodore 1084S Color Monitor with Microtouch Screen, CDTV, and an Amiga 1011 Disk Drive. The unit is designed to serve the purpose of an average kiosk: give information, but use CDTV to convey that information to the user. The CDTV kiosk also allows for optional enhancements such as a Star SP349 Printer, a magnetic stripe card reader, laser disk player, bar code reader, telephone handset, modem, and of course, custom software applications.
From Commodore's CDTV Publishing, there was the Guinness CDTV Disk of Records, Music Maker, The New Grolier Electronic Encyclopedia, and a super new version of Defender of the Crown, created by Jim Sachs. Jim has completely redesigned Defender oftheCrown. He has improved the graphics, sound effects, music and playability, and he did the majority of the work himself. Another new title called NASA, The25th Year from Troika Multimedia is going to be interesting. The disc features a complete history of NASA and includes stunning footage of some of the more fa mous Space missions.
A new trend accompanies CD+G for CDTV, Karaoke Discs. Karaoke Hits I & II and Christmas Karaoke, from Music Sales, were on display. Through a stereo hookup,the karaoke discs allow the user to sing along with the music as the words to the song come up on the screen. With the available genlock for CDTV, you can place live video in with the CD+G to create vour own video. Keeping with music.
Microdeal Limited showed several new items for CDTV. CD-Remix Version 2 allows you to re-mix your favorite audioCDor cassette tape.
You can add all sorts of sounds, edit songs, or create yourown versions of popular hits. Voice Master is a microphone and interface forCDTV.
It supports many CDTV programs where a voice-over is possible. It can also be used with voice FX to alter your present voice or create a new one.
Research and Development The future of the Amiga and of CDTV is always an important topic. From what was seen at the show, the future of both product lines remains promising. Over the next year.
Commodore hopes to make improvements to all of its products, improvements that will enhance the ease-of-use of our favorite Commodore computers and improvements to CDTV. The further development of these products will be a definite benefit to all users and hopefully willgiveCommodorea marketing and sales edge over its competition. The new and improved marketing of CDTV is definitely a step in the right direction.

Bytes The latest in tips, workarounds and upgrades John Steiner 11 by John Slei product: Platinum Scribble!
Re: Patch source: Email Larry Diener sent Email via CompuServe regarding a problem he encountered with Microsystems Software's Platinum Scribble!. He writes: "...I have come across a bug in MicroSystem Software's Platinum Scribble] Version 3.05. The program works property on a 25MHz A3000 using the prerelease Kickstart and Workbench
2. 03 (version 36.XX). Unfortunately upon receiving the release
version 2.04 software (Version
37. XX) and installing tile super- kickstart, 1 tried running
Platinum Scribble! And it loaded and appeared to run just
But, when attempting to cut, paste, copy, style, or otherwise use the mouse for any operation, nothing worked. 1 called MSS and the technician said that they were aware of the problem and were working on a patch for it.
"...There is an additional problem which may or may not be related. It occurs when taking advantage of horizontal overscan there is a toggle on V3.05 under the preferences section of the program. It seems that depressing the RM button causes the entire screen to shift to the right by approximately one column. When the button is released, the screen returns to normal. While this is not destructive, it is extremely annoying. A simple work-around is not to utilize the horizontal overscan feature of the program."
I contacted MSS technical support, and received a reply from Andrew Apold, their technical support adviser. He acknowledges the problem that Mr. Diener has, and they have a fix for it. If you are having problems with version 3.05 under release version 2.0 Workbench, you can request a repaired version. The fix is available as a patch, which MSS will provide over the phone to anyone who is technically oriented. The patch is also available through the MSS BBS system (407-790-0774). To whose who do not feel confident with patching their software, they can send in their master disk and S9.95, and
MSS will apply the patch for them, For anyone like Mr. Diener who already paid the S9.95 to receive a version 3.05, the patched version will be available at no charge. All new disks are going out properly patched. With regard to the screen shift noted by Mr. Diener, Mr. Apold pointed out that this is a feature of version 2.0 Workbench. If a user presses the RM button when running overscan, the screen automatically returns to non-overscan mode to ensure that all menu options are visible and accessible to the mouse. I have noted the screen shift in several applications, and though it might
be annoying to some, I especially like the feature when using DehixePaint in overscan mode. It makes accessing menus much easier.
Product: Atonce re: Workaround source: Phone contact Last month, I commented about problems that a reader was having with his A2000 that occurred when using Pagestream in combination with a GVP accelerator and HP LaserJet II printer. Robert Miranda, a technical support staffer from GVP, called to comment that he is puzzled bv the bug report. He commented that they have received no complaints from others using that same combination of hardware and software.
He also noted that their marketing department uses an A2000 with the GVP Series II 33 Mhz board, and an HP Laserjet IIP to create Pagestreamgenerated newsletters. They also have at least one other similarly configured system and are not having problems. He suggested that our reader check for the possibility of a defective printer driver or possibly a hardware problem with that reader's parallel port.
While on the phone, Mr. Miranda also commented on a bug fix he came across for those people who have an Atonce card from Vortex. The symptoms include unstable operation after booting, or the system hangs during the memory test function upon power up. The problem can be corrected by changing a capacitor on the Vortex board.
According to Mr. Miranda, capacitor C3 on these problem units is rated at 270 pf. That value of capacitance should be increased to 490 pf. The capacitor is surface mount technology, and requires replacement using proper surface mount component handling techniques to avoid damage to the Atonce board, if you are not equipped to remove and replace surface mount components, take the unit to a properly equipped technician to prevent further problems.
Product: V2.1 SetClock re: Workaround source: Mail Last month I received a letter from Pete Guerin of Seattle, WA, regarding the 1CD AdRAM-540 board for his Amiga 500. As 1 mentioned, he has found that the real-time clock appeared to be highly unreliable. He had read in an earlier "Bug Bytes" about being sure to use version 1.2 of SetClock, as that made the dock more robust. Pete got the opinions of a couple of acquaintances who are electrical engineers, and they provided a solution which included pulling the write-enable line from the dock chip's socket and hard wiring a switch to that line
to ensure that the clock is set only specifically when desired. He also complained of a corrosive residue he found on the board that he thought was left there by the manufacturer. I promised that I would find out more details on his hardware correction before I published the details. I wrote to ICD and asked about these problems and Chris Edgin of ICD Technical Services replied: "Mr. Guerin was correct in assuming that he should use the vl.2 of SetClock to cure his battery-backed clock problems, We have discovered that it is a possible bug in the 1.3 and 1.3.1 version of SetClock. Setclock
versions 1.3.2 and higher have been fixed. The next step is to enter the CL! And type 'SETCLOCK RESET' then go ahead and set the clock through preferences. This should clear up his clock problems."
Mr. Edgin does not recommend the hardware repair suggested by Mr. Guerin as Circle 104 on Reader Service card.
Version 1.3.2 SetClock fixes the problem. The powdery substance referred to in his letter is not any kind of corrosive residue, but flux residue left from the soldering process; it is not harmful to the circuitry, board. Mr.Guerin also asked about a low-level format utility for MFM drives. His MFM drive is being driven by a Commodore 2090 controller. He has tried several alternatives, none of which are capable of a low-level format. Commodore Express was not able to help either, if you have some expertise in this area, and would be able to provide information or a source for a utility' such as
this, let me know; I'll pass it along in a future column.
Product: GVP Accelerator SCI Combo re: Workaround source: Reader mail Terrv Morris of Carlsbad, CA, writes to help keep others from having a problem that is as frustrating as the one he encountered when he added a GVP Accelerator SCSI combo card to his system. He hooked up his Fujitsu 130MB internal drive and his 44MB Syquest external drive to the system an Amiga 2500 and began to have problems almost immediately. The internal drive kept giving him errors, even though he tried reinstallation, low- level format, bad block remap, and DOS format. The errors are false, never show up in the same
spot, and are never fatal clicking on retry works every time. The problem became markedly worse when he upgraded to the release v ersion of Workbench 2.0. The only thing he could do that stopped the false errors on his Fujitsu drive was to disconnect the Syquest drive. GVP provided several suggestions of things to try, and his local dealer also made several suggestions to no avail.
"After two weeks of hair- pulling trial and error, I made one last call to GVP hoping to exchange the board or get my money back! I reached Bill in technical services, who told me to tryr one last thing first, to remove the terminating resistors in the SyQuest drive and it worked." Drive termination appears to be one of those "voodoo" sciences wherein there is much mystery and false information flying around. If you have some expertise in this subject, it's time to enlighten the rest of us.

Holly, NJ, writes with a problem he is having with multiple third- party'products installed in his A2Q0O system. He recently upgraded to an A2000 and moved the Atonce board from his A500 using Vortex's A2000 adapter board. He then added an TVS GrandSiam multifunction card with a Quantum 105 LPS SCSI drive, which co-existed without problems on his Atonce-equipped A2000. Flis problem began when he added DKB's MegaChip 2000. His hard disk went awry, and when he reinstalled
the old Agnus chip, his hard drive data was trashed.
Since both GrandSiam and MegaChip worked with the Atonce separately, he assumed the conflict was not related to the Atonce. He called DKB and wrote IVS, and got a report from DKB that a handful of others had complained of a conflict between the GrandSiam and the MegaChip boards. He then added a GVP Combo 33 accelerator card, planning to use its SCSI controller instead of the controller built onto the GrandSiam. He reinstalled the MegaChip when the GVP controller all of a sudden generated puzzling messages that related to the Atonce card.
Nor could the controller locate DFIt):. He pulled the Atonce card, returned it to his A500, and all of his conflicts between the MegaChip and SCSI controllers disappeared. If y'ou have a MegaChip, SCSI controller, and an Atonce board which all live together in harmony in an A2000, pass the information along. Mr. Zahnle also commented that he found an MS- DOS mouse driver for his Atonce from a BSR software bundle that he bought through the DAK mail order catalog. The mouse driver works fine with the Gem programs that were provided in the DAK promotion.

The disk contained a program which he thought would be of interest to Robert Beltz, the visually impaired Amiga owner who spoke of a need for products that would be of assistance to those who are similarly handicapped. In "Bug Bytes," V 6.12, Mr. Beltz mentioned another product which apparently will never be completed. Mr. Moats' background utility uses the Amiga SPEAK: device. The program is called PCMenuSpeak, and it allows
the user to browse through menus from the keyboard and have the menu, menu-item, and sub-item text spoken. In addition, it lets the user run the program menu items from a keyboard similar to the way IBM PC menu choices work. He usually sells the program for $ 10 but asked me to pass it to Mr. Beltz.

• AC* Version 2.0 KickDOS.Bench?
I currently own a stock Amiga 3000 16 50, apparently one of the early 1991 models.
I’m constantly reading reports about new versions of Kickstart, AmigaDOS, and Workbench being released by Commodore, and 1 have become confused about the process of upgrading to these new versions.
The profusion of version numbers of various aspects of the system software surely needs clarification. The "version" command under Workbench 2.0 shows Kickstart version 36.143, Workbench version 36.68. Also do these early 3000s use AmigaDOS 2.0 or 2,04, and is AmigaDOS in ROM? Is the "long-awaited release" of Workbench 2.0 ROMs (or is it AmigaDOS ROMs?) Pertinent to 3000 owners? What are the latest version of things and their formats disk, ROM, etc.? What is Commodore's policy regarding upgrading early 3000 machines?
Finally, a recent issue of a computer buyer's guide stated that Commodore has decided to discontinue the 16MHz version of the 3000. Is this true? Thanks for any information you may offer.
JoeCampana Plymouth, MI You're not alone in your confusion, loe. There arc miuiy original A3000 otvners who are puzzled about AmigaDOS release 2 versions. When the A3000 was originally released, the KickStart was loaded off floppy or hard disk like the A10Q0 startup. Since the AmigaDOS release 2 version supplied with the A3000 was not the release version, and still going through some major fixes, it was easier to distribute new releases by diskette rather than by ROM. The official release of AmigaDOS release 2 is 2.04 with KickStart v37.175 and WorkBench v37.67. Many of the newer 2,0-on!u
products do require KiekStart v37 or higher.
As you know, there is an Enhancer Kit available to upgrade owners of A500 2000‘s to AmigaDOS
2. 04 (ROM upgrade). But what about A3000 owners? Just go to your
local dealer and pick up your free A3000 upgrade (some dealers
may have a minimal copying charge). This is a five-disk
AmigaDOS 2.04 upgrade for owners of original A3000 models. All
new A3000 series models will come with AmigaDOS 2.04 in ROM.
We can’t confirm nor refute the report on the discontinuation of the 16MHz A3000. Ed. Propeller Heads=UN!X Professionals?
Regarding your November 1991 editorial both Mr. Kizior and The Bandito need straightening out. I will address Mr. Kizior's problem first.
1 can understand Mr. Kizior's taking offense at being called a "propeller head" by The Bandito clearly a derogatory epithet, although I would not hazard to pin it down beyond that. What grates on me is Mr. Kizior's reference to the Amiga as a toy computer. Now 1 can't tell from Mr. Kizior's letter what computers he uses on a regular basis, nor what he does with them. "UNIX professional" has about as much informational content as "propeller head." But since he's so critical of computing power, it must be pointed out that his personal lack of power is primarily his own fault or circumstance.
Mr. Kizior's A1000 is five or six years old, and from the sound of his letter unexpanded. Unless he's running with at least an '030, an SCSI hard drive, xxMB of RAM, and Workbench 2.0, he really has no business commenting on the capabilities of the Amiga. The above configuration can be achieved on that A1000 he's so attached to.
As for The Bandito, although the concept of his column "Roomers" is good, its implementation is frequently poor. Far too much emphasis is given to games. Tire column is supposed to focus on Amiga- related rumors, such as upcoming but not officially announced products. Instead, it’s often the Nintendo News and information about products that have already been officially announced. Keep "Roomers."
Rehabilitate The Bandito or shoot him whichever is quicker.
John Malone Brantford, Ontario Canada Lest anyone who hasn't read The Bandito's September column come to the conclusion that The Bandito singled out Mr. Kizior for caricature and ridicule, let us quote from "Roomers": "What is it about UNIX that fascinates these companies?,..Have you ever tried to use a UNIX application? Yuck. Leave UNIX to the propeller heads, OK?"
As for the column concentrating on games where instead it is "supposed to focus on Amiga-related news," bear in mind what the disclaimer at the beginning of the column states, simply that The Bandito gleatis his rumors "from whispers within the industry," not just info on unannounced new products, nor on anything else in particular, so broad is The Bandito's charge. Looking back over several issues, we find the column focusing on hardware, software uof all of it games BBSs, and on the reorganization, sale, or failure of companies, several of which happen to be game developers, so brittle can
that business be.
Although he reports yet-to-be-announced new products quickly to AC in his column submissions, some companies dread being scooped by a third party, so then wake their announcements ahead of schedule when they suspect that publication by a third party is imminent. Maybe it's the case of their having their own sources in the publishing industry, a sort ofcounter- Bandito!
Over the last several months, sonic renders have ordered The Bandito fired, banned, whipped, imprisoned, and even lobotomized. This is the first time that anyone has suggested homicide for one of AC's most nettlesome and popular columnists. Ed. GAC Has Demonstrated WordPerfect in Halls, at Stalls and Malls We've owned, supported, and promoted WordPerfect for many years. We considered it a good word processor and believed that the company would stand behind its product.
Our club has demonstrated WordPerfect at meetings, in mails, and at computer shows. We have shown it to several gatherings of Amiga enthusiasts, stressing its excellent word processing capabilities. We all expected an upgrade, You wonder why your Amiga center doesn't garner enough sales to support improvements. Mabe it's because WP is four years behind other word processors for the Amiga. Your competition has taken the Amiga capabilities in color, sound, multitasking, and animation and run away with the market. Don't tell us WP isn't selling enough. We know that! Instead explain to us why
you don't compete to get the market share on the Amiga that you deserve.
We have members waiting to upgrade to 5.1, and the Amiga community is holding its breath. Now we hear that your company may not continue to upgrade. This is a sad commentary for such a company. Will you please reconsider?
Bob Scharp, Secretary Gateway Amiga Club Bridgeton, MO Unfortunately for those waiting to upgrade, WordPerfect Corporation has decided not to release any further versions of WP for the Amiga, apparently because the number of new purchases of v5.i would not justify a new release. According to WordPerfect Corporation, all development has stopped but continued support is promised to any Amiga WP owner at (800) 321 -

List". This is a little more straightforward than copying, deleting, and then recopying.
The second suggestion is to skip the whole thing and make them resident - "resident c list", for example. This is available to anyone with Workbench 1.3, pretty widely in use since it has been around for a few years and applies to commands run from the 'shell', the first tool icon that shows up when the "Workbench" disk is open.
Anyway, with 'resident' only one copy is ever in memory, rather than the two copies (one in RAM: disk and the other executing) that the other method uses. It takes an extra IK to keep the 'list' command in the RAM: disk over making it 'resident' and an extra 11,640 bvtes to actually run it.
Also, part of the 'shell' is the ability to run script files if the 's' attribute is set for the file. For Keith's example, the command "protect s:ramc +s" would suffice. Then just typing 'ramc' would run the script. 'Execute' is needed only for 'dir.
The method that Keith mentioned, using the RAM: disk, is good for programs that don't have a 'p' in their attributes list. Of the few programs in the 'C' directory that don't conform, most are likely to be used from the com and line. The only exception 1 can imagine that would be useful is ICONX, hut to use that requires sufficient experience so that its use will not be a hindrance.
Of course, Sam Ammons' "Memory Expansion for Your 500" [v7.1. p.20) got to the point about using 'resident'. Sam suggested that it is a trick to find out what is being requested by a "Please Insert..." I found that SttoopDos, FF 451, really helps to nail these troubles right away.
Sam is a bit off with memory allocation.
The only memory that would cause programs to fail is that which is above the 16MB limit if the 68000, but to get at it requires a 68020, '030, or '040.
It is more often the case that some programmers assumed that machines with 1MB of memory had 512K available to both the custom chips and the CPU, aka Chip RAM, They would try to force some data structures into 'fast RAM'. But on a 1MB A500 or A200, it may all be 'Chip RAM'. The program would then die, claiming there was insuficient memory to run.
Among other articles, 1 really enjoyed Rick Manasa's article "Help for the Help Key [d7.1, p.28J." Although I haven't needed help like that for a long time, the spotlighting of two favorite products, Machlll and Gizmo:, was pretty nice. I got Gizmo when it first TURN YOUR DCTV IMAGES INTO ART!

Came out, one of the best assortments 1 have ever used. Oh..,MachlH is not I’D. At least the disk I have says that the copyright belongs to Brian Moats.
Thank you, thank you, thank you, Doug Thain [v7.1, p.6b . While I hadn't actually tried 'open("SER:","rw"), 1 was just inches away from it. Even if that would work, the explanation of how ports and devices work was absorbing.
On to The Bandito: if he wonders what's holding back the Amiga, it's the poor support, not just the hardware. The Macintosh might not have ali the fun chips, but for a few percent more in price, you get a machine with available software a thousand percent ahead in quality. Even the CDTV system screams with poor software development. I'm still looking for an entry- level spreadsheet without a cartoon look and feel, and a bunch of bug reports from users.
GVP, Consultron, and Bill Hawes to name a few have been a plus. EA, Aegis, and Coast-to-Coast make the Amiga look toy-like. What's the difference? The first three meet needs in an expert manner, but the last three have shipped crippled software and then asked for money to upgrade to a different crippled condition.
In three years, the Amiga may go the way of the C-64 and its real ancestors, the Atari 400 and 800. Eight years is a long time for any computer system to remain unchanged, and the Amiga has already had five. It lias become an expensive game machine. Notice AC's coverage, v7.1, p. 63, of the [BartjSimpsonAmiga and new games in "European Excitement" and "New Products." I think these say it all.
Well, i'll get back off the soapbox now.
Before 1 sign off, lei me remind you that Mac and IBM. Buyers don't write you and don’t care. It's not too late for the Amiga, but time’s running out.

Please, there must be a better solution. 1 urge you to take the lead in finding it.
Ronald Accardy St. Cloud, FL In the best of all possible user worlds, there should be shows spread throughout the year in Bangor, ME, Ft. Lauderdale, FL, Tacoma, WA, and San Diego, CA, as well as in some locations like Davenport, IA, El Reno, OK, and tshpeming, Ml, to acommodate main . However, "trade journalists" and small developers, who don't "write off" expenses but pap them with real currency, would face budget depletion pretty darn quick.
Remember, that each show means taking several key employees away from their work al journals and production companies, lodging, and feeding them. Nevertheless, we'll continue to search for a compromise on show dates and locations. Ed. Good work, Dave, in commenting on and adding points to several of the stories in the January issue. Also, others have remarked on what a popular game machine the Amiga is in the U.K. as well as on the Continent. Let's hope that its full potential is realized soon by other than just game developers. Ed. An Amiga Trade Show in Davenport, IA?
I disagree with your editorial complaining of too many Amiga events in the U.S. My problem is that that are too few that I can get to.
1 think a little geography is in order.
Look at a map of Europe and compare it to a map of the U.S. having the same scale.
Europe is small! Add to that the fact that Europeans have something we lack: a relatively inexpensive, efficient rail system.
Exhibitors can manage with fewer shows and still reach many more Amiga users.

¦AC* I'm a long-time Amiga user owning a greatly expanded A500; I'm also a working stiff. I can't afford to fly one or two thousand miles to attend a show, My realistic limit is what I can drive to and return home in one day. This amounts to a 200-mile radius from my home, involving eight hours of driving, and leaving little time to actually attend the show.
Being a lowly user and not a trade journalist, I can't write off things like meals and lodging, just driving 400 miles would add about S60 to the cost of attending the show.

Well, gentlemen of the trade press, there have been Iwo Amiga shows here in the past several years. Contrast that to the several MS-DOS-oriented shows per pear.

P. O. Box 2140 Fall River, MA 02722-2140 Spacewrecked by Miguel
Millet Ugh!! Getting up on a Monday morning is hard enough,
but when you've been in cybernetic sleep for seven years, it’s
The computer, unfortunately, has not awakened you to tell you that you're almost home, but to tell you that it has discovered a fleet of 20 ships which may get you home faster. The only problem is, all 20 ships are inoperational, and you won't be able to move any of them until you fix them all. Thus, you have two choices either spend an indeterminable amount of time trying to reach Earth in your hopelessly damaged spacecra ft, or take the time to man each ship and repair them individually. Considering vour're Spacnvrecked, 14 billion light years from Earth, what's your choice?
It would have been a much easier decision if you only had one ship, but this fleet was built at a time when a brain-damaged designer had them all interlinked no ship can leave without the others. The Darwin Biological Survey fleet, as these ships are known, were on a mission to explore alien worlds and collect typical species of life found on these worlds. The crew and her specimens are alive, but a bit crazv since they weren't awakened from cryogenic sleep properly when the fleet time- warped into an exploding supernova. So not only do you have to repair each ship, but you have to
defend yourselves from insane lifeforms.
To accomplish vour mission, unless vou decide to wait the 14 billion light years to get home, you must explore each ship, inspecting for and repairing the damage with pa rts which are loose all over the ship. If you're lucky, you'll find one or all of the ship's droids, which can be progranamed to help you repair some of the damage.
Moving about the ship is easv, using the mouse to press directions on a movement icon located in the middle of the screen.
Your view is represented by a screen on the left, in which you can shoot your enemies but cannot pick up the items you may find. To pick them up, you press the inventory icon found on the lower right portion of the screen.
Other icons present on this screen allow you to interact with functional computers you find on board, as well as program and instruct your droids to find spare parts and repair crucial subsystems. If you find you've collected too many items, you can offload them to some of the droids to make vour load lighter.
Game graphics are average, butmore than suitable for the game at hand. Unfortunately, the programmers decide to make the You’ll run into lots of strange characters while trying fo repair the ships.
Crosshairs on your weapons jump (supposedly due to the amount of your adrenalin), rather than having the aliens move about. Thus, defending yourself can become rather tedious. Other than this, however, the graphics are adequate. At the lower left of the screen, there are icons representing your health status. Tire more you look like a skull, the worse off you're doing. There's an animated heart also. A yellow heart means that you may have to get some medical attention. The sound effects also include a heart monitor, which audibly tells you how your character is doing.
The game is presented on three double-copy-protcctcd disks. Not only do you have to identify an alien creature from the manual, but you can't copy the game onto a hard disk. There is a provision to save a game in progress, as well as turn off the sound effects. The manual isa little hard to follow. All the information you need is in there, but you may want to try to make your way through a few times in order for it to make a little more sense.
Despite its deficiencies, Spacewrecked is a challenging game. Each ship has three levels, a nd the number of rooms and their location change from ship to ship.
Your obstacles are many and you have to collect several items to repair each ship. Even with the droids helping you, this can take some time. Once armed with appropriate weapons, your droids can also be programmed to defend you. Each ship can take a couple of hours to explore and repair, so completing your goal can take a lot of time. The game really is a type of space-aged dungeon, where your treasures are the parts you need to repair each ship. Although it wouldn't really be fun tobestrnnded that far from home, Spacewrecked isa nice way to see if you'd make it back alive.
Arachnopliobia by Jeff James Based upon the popular movie of the same name, Arachnopliobia brings out the spider-stomping crusader in Amiga owners everywhere. The game begins with the player being accepted into the esteemed Delbert McClintock Bug Elimination Agency, which promptly outfits the player with the required accouterments of a soldier of spider misfortune.
The storyline is loosely based upon the film. In summary, viciously deadly spiders (offspring from a deadly South American species) have begun infesting towns across America, endangering the lives of thousands of innocent citizens. Only your employer has the pesticide which is concentrated enough to kill this new breed of spider: virulent "Toxi-Max," the ultimate in bug extermination liquids.
Your goal is simple. Attacking this eight-limbed menace one town at a time, the player must exterminate his way through an abundant number of towns, eliminating all of the soldier spiders, all the egg sacs, and thequeen spider before advancing on to the next town. Eventually, if the player has done well at exterminating the spider menace at home, the United Nations will send the player to the jungles of South America, the stomping grounds of the spider species which started this whole mess.
Gamepla v is primarily of an arcade nature. When the player arrives in a new town, an overhead map clearly shows allot the spider- infested homes. The player then must manuever his or her vehicle to a house that needs exterminating, then press the fire button. The carstops, and your on-screen alter ego dashes into the house. Once inside, the action shifts to a side view, displaying the plaver and several levels of the house. Using your spray gun filled with Toxi- Max and a supply of "bug-bombs," you must eliminate all of the arachnids on the premises, including a single egg sac. Once one
house has been cleared of spiders, the player must continue through all of the homes in the town until the queen spider has been found and destroyed. Only when the queen spider in each town is defeated may a player advance to the next level.
The graphics and animation are acceptable, making good use of the Amiga's 32-color mode.
Digitized sound effects accompany most of the actions in the game; players will hear Delbert proclaim that "The cavalry has arrived!" When entering a building. After the player has successfully sprayed a spider, Delbert occasionally shouts such things as "Sit on a tuffet!" And "Too quick for ya!" When a player clears a house, the response is either "Another satisfied customer!" Or "Let's bug outta here!"
Arachnophobia is geared for younger children; my 8-year-old nephew thoroughly enjoyed the game, while my interest was of a milder nature.
Arachnophobia requires 512K of RAM, and it can be installed on n hard disk. Copy protection is in the form of a dark red "copy-proof" spider identification chart. The game ran fineonall the Amigas I tested it on, including the A3000.The manual claims that the program does not support AmigaDOS 2.0, although it seemed to operate fine when 1 tried it.
All in all, Arachnophobia is a pleasantly simple arcade action game with crisp graphics, plenty of digitized sound, and an affordable price tag. Tailored for kids, Arachnophobia might not be that interesting to adults. But if you're tire type of person who cringes visibly at the sight of any small, scurry ingarachnidson your bathroom floor at night, this game might just be your chance to get even with those little critters.
More Lemmings In Jeff James As one of the most popular Amiga games of all time, Lemmings has captured the hearts and minds of nearly every Amiga owner.
Rescuing hordes of tiny, dull- witted rodents from certain destruction has become second nature to many of us. Demos have been created dealing with them (witness Eric Schwartz' Anti- Lemming demo), and even CDTV, MS-DOS and Atari ST owners have had the opportunity to rescue a Lemming or two.
So how can Psygnosis top their best computer game success ever? Oil No! Mori’ Lemmings (ONML), the title of Psygnosis' new sequel to Lemmings, is an answer to thatqucstion. Someone once said that "more is not always better," but in this insta nee I'd have to disagree.
Psygnosis released two versions of ONML a stand-alone version and an add-on version.
The add-on version requires the original Lemmings program disk.
ONML consists of a single diskette which must be booted before you insert any of your original Lemmings diskettes. After a few disk swaps, tire ONML disk remains in your disk drive and the game commences. The stand-alone version runs by itself and does not require theoriginal Lemmings nor any disk swapping. Just pop in the disk and play!
Veteran Lemmings gamers will find that the interface is basically unchanged; ONML is simply adds 100 new levels of game play. Broken into five levels of difficulty, including new two- player levels, 1 found that the higher levels of ONML were exceptionally difficult. The first 20 or so seemed ra ther simp le; f i n i sh- ing them was a snap. Players who found the higher levels of theoriginal Lem mi ngs to be too ea sy a re i n for a much rougher time. On the Levels 1 managed to herd my tiny, green-haired charges through, I saw new traps, new terrain, and heard hew music to accompany
gameplay. ONML requires 512K and runs fine on accelerated Amigas, including the A3000. Just as the original Lemmings, the ONM1. Is not an AmigaDOS format diskette, so you'll be unable to make a backup.
ONML is just what most Lemmings aficionados would want, although 1 do have a few small criticisms. The music in DIVERSIONS ONML seems not to be quite as variedasiatheoriginal Lemmings, and 1 found myself turning off the music to concentrate on saving rodents in silence. Also, I was hoping that Psygnosis would have made ONML hard disk- installable. More and more Amiga owners own hard drives, and it's a shame thatwe can't enjoy the same convenience that the MS-DOS ownersofLemmingsare privy too.
Quibbles aside, ONML is a must buy if you're a Lemmings fan. I've heard that Psygnosis has plans to continue expanding the Lemmings universe in the future, including a forthcoming "Lemmings Construction Set," which will allow players to make their own Lemmings levels. With support like that, I see Lemmings remaining a centerpiece of every Amiga gamers software library.
That's right, they're back: 100 new levels of "Lemmings-mania."
DIVERSIONS Conflict: Middle East by Jeff James The long-standing feud between Israel and its Arab neighbors is the focus of SSI's wargame for the Amiga, Conflict: Middle East (CME). A brigade-level simulation played on a hex-grid map, CME allows players to serve as either the leader of a combined Arab army or as supreme commander of the fsraeli military forces in one of two separate scenarios: the 1973 Arab-Israeli war, ora hypothetical conflict set in the 1990's.
CME's playing interface is a refined version of the one used in an earlier SSI wargame, Red Lightning. Except for when entering the password copy protection ornaminga saved game, all aspects of the game are mouse controlled, making issuing commands during gameplav a snap. C.ameplay is broken down into a series of AM and PM turns, with air operations, unit movement, and other options available during each of those bums. CME can be played solo against the computer (with the computer assuming control of either the Arabs or the Israelis), or it can be played with two human players. The
computer can be set toa variety of difficulty levels, with the highest being extremely difficult to defeat. New players should set the computer on the lowest level and get some experience before tackling the higher difficulty settings.
Trouncing your opponent, either made (if silicon or flesh and blood, requires that you pay special attention to the strengths and weaknesses of your forces. When commanding the Arabs, the player must generally rely upon two advantages for victory: strength in numbers and massed artillery. In playing both scenarios, 1 discovered that 1 had thebest luck against the Israelis whenl massed my plentiful artillery around any major ground advance. Since Arab forces outnumber Israeli units in both scenarios, making combined attacks on enemy units from as many directions as possible usually
resulted in victory. This can be difficult at times, especially when CME restricts players to stacking a maximum of two units per hex. To a lesser extent, 1 found that pressuring the Israeli player by simultaneous advances from Syria to the north and Egypt to the south spread out his defenses enough fur me to succeed. These princip les won't (and didn't) apply in every instance, but they worked pretty well when I used them.
The airstrike screen in Conflict: Middle East When commanding the Israelis, the player has the advantages of greater unit flexibility and more effective air assets. While Arab units can be ground down to uselessness by attrition, Israeli forces can be swapped between units, allowing the creation of massiveand brutally lethal combat groups. Instead of being forced to move shattered units to the rear (as the Arab player is forced to do), the Israeli player can salvage damaged units to create larger, more lethal groups. Israeli air power is also considerably better than the Arab player's,
dramatically so in the 1973 scenario. A concentrated series of air strikes on advancing Arab ground units can mete out a surprising amount of punishment.
More hints and tips for victory can be found in the excellent instruction manual. The authors spend a considerable amount of space discussing the formulae used to generate their outcomes, something more technically minded garners will enjoy. Stat-hungry wargamers will a Iso appreciate the detailed listings of all the military equipment used in the game.
CME supports hard drives and runs fine on accelerated Amigas, including the A3000.
AmigaDOSZ.O is fully supported, and CME will operate without difficulty on any 1 MB Amiga, Alas, I do have some minor gripes: the computer opponent often takes quite a while to plan its moves (especially on an A500), and CME refuses to acknowledge the presence of any floppy drive other than DFO:. The graphics a re a tri fie plain, and there is no sound or music played during the entire game.
While that might be acceptable for a wargame, it would have been satisfying to hear the rumble of firing artillery and the explosions of a successful airstrike.
As a purely strategic exercise, CME doesn't disappoint. Playing CME was also an enlightening experience, letting me look behind tod ay's head lines and perhaps gain some understanding of the situation that has been the source of so much conflict over the past four decades. While its small number of scenarios and lack of true Amiga support may discourage some gamers, CME is nevertheless a playable, challenging, andsurpris- ingly enlightening softwa re d [version.
Silent Service 11 by Miguel Mulct Beneath the oceans of the world lies a lethal force. A force which has played a cat and mouse game with its opponents since its inception. Operating silently under the waves, U.S, submarines have protected citizens by maintaining a constant vigil posing a constant threat to enemies. Submarine warfare has always been an important part of U.S. naval operations, but really came of age during World War II. Although submarine casulties were extremely high, the commanders of these vessels almost completely wiped out the Japanese merchant marine. Do you have
what it takes to join the Silent Sendee?
Silent Service II is the sequel tu MicroProse's original World War il submarine simulatation, which first came out in 1985. Like the first game. Silent Service II al- lowsyou to command a submari ne of the World War IT era. Your goat is to patrol the seas of the Pacific, engaging in combat with as much of the Japanese fleet as you can.
Unlike the original, the new game sports better graphics,better sound effects, and a better manual.
After identifying a ship displayed on thescreenfrom pictures in the manual, you're ready to decide on how to approach your career asa submarine captain. You can start by commanding a training mission against unmanned targets, or you can undertake one of eight single historical battles. If you have a lot of time (in the hours to days category), you can go on an entire war patrol or start a war career, which ends when the war ends. The four difficulty lev els add an extra element of challenge to these scenarios, because you can choose to be virtually invincibleor realistically vulnerable.
Besides these options, you can command one of nine progressively better submarines, use flawless or historical torpedoes, and choose the war zone in the Pacific you wish to patrol.
On board the sub, you have several screens with which to occupy votrr time. The information pane! Displays the navigational charts, as well as your heading, speed, and number of torpedoes available. Along thebottorn of each screen are several icons, allowing you to look through your periscope, view the battle from the bridge, or man the deck gun.
Keyboard equivalents mean that you can disable or ignore the icons, which during the heat of battle tend to react a little slowly.
The gauges screen quickly reveals to you the conditions of the submarine. Course and speed, water temperature, depth, battery level, engine room telegraph, depth under keel, fuel gauge,and tube indicators are all present on this screen. The damage report screen gives you even more detailed information about sub operation, shovvingyou what systems are d amaged and or whether they are repairable or not. Most vital equipment must be repaired at a friendly port, cutting your war patrol short.
Actual game play is much fun, although your contact with enemy ships may seem fairly slow unless you acclerate time a bit.
After all, the Pacific ocean is quite large. Although it takes a little time to learn all the commands, a short tutorial in the manual as well as a keyboard template makes things much easier. Since the template is for the 500 2000 3000,1000 owners will have to lay it in front of their keyboards, or prop it up nearby. Although there is a lot of action to the game during actual combat, you have to ha ve the cunning of a fox to outmaneuver and sink many of your opponents.
Strategy, therefore, plays a large role in the game as well.
Game graphics and sound effects are well done, much better than the original. The Amiga graphics aren't quite as nice as the VGA graphics shown on the box, but are better than expected. Sound effects are failv realistic, as well.
The mouse can be used to maneuver the submarine, deck gun, and periscope, but using the keyboard commands is actually easier once you get the hang of it. The 128-page manual not only explains the commands,but delves into the strategy and tactics of submarine warfare. The two-disk set will install on a hard drive, but if you have an earlier version the install program may not work properly.
Microprose's bulletin board has die correct install program, or you can return the game for a newer copy.
Overall, Silent Service 11 is a well-done sequel to the original.
Gameplay is enhanced bv the improved graphics, sounds, and game features. Although gameplay issimilarto the original, the "extras" make Silent Sendee 11 exciting and interesting to play. If you'd like to return to Pearl Harbor circa 1V41, here's your chance.

L DIVERSIONS Murder!
Bu Miguel Mulct One of our family favorite board games has aIwaysbeen Clue.
Sitting around the game board on a cold winter's night, family members would look suspiciously around the table trying to figure out who killed Miss Scarlet, and where and how they did it. Well, if you'd like to try your hand at solving up to 3 million cases, you should investigate Mttnk’r!
In this game by U.S. Gold, the player becomes a sleuth trying to solve a murder between the years of 3915 and 1945. The murder has taken place in one of several different homes, although your investigation is thankfully limited to one home at a time. There arc also four different playing levels, just to add to the chal lenge. U nlike the classic board game, there are many more suspects and potential murder weapons, which means you'll have to make good use of the 24 hours you have to solve the crime.
Using an icon-driven interface, you maneuver around the premises interrogating witnesses and collecting evidence. Pressing the right mouse button reveals either an arrow, which you point in the direction you'd like to move, or a magnifying glass. Pressing the left mouse button allows you to carry out the action. The icons on the far right portion of thesereen allow vou to interrogate a witness, see a map of the house, examine die notebook in which you can record vital dues, take fingerprints and compare with them others, collect exhibits, and finally, make your arrest.
To make an arrest, you must find out who, where, and with what the murder was committed.
Falsely accusing a suspect disgraces vou and ends the game, while correctly identifying the suspect brings you fame and glory.
Arrivingat a conclusion, however, can be most difficult. Since there are so many characters, weapons, and locations, it can take a long time to reach a final deduction even at the easy levels.
The simple interface makes the game easy to play. Although the main playing area is in black and white, it adds to the ambience of the period you're investigating.
Sound effects are sparsely used and generally not missed, and although the graphics are not spectacular, they are more than ad- The entrance hall is where you begin your investigation.
Equate. The one-disk game is doubly copy protected it uses both a copy protection on-diskand a key word lookup in the manual.
The rear of the manual features a synopsis of several famous murders many of them quite morbid in nature and not suitable for voungsters.
Even on its easiest settings.
Murder! Can be difficult to play.
There are almost too many items and suspects,and you'll realiy flex the muscles in your brain to figure out whodunit It can be done without despair, but you'll have to be very patient during your investigation. This tediousness is the game's greatest shortcoming, if you love to solve a great mystery, why not try solving a Murder’?
By L. S. Lichtniann All dilettantes, please take one step back from the computer screen. Action Stations! Is a serious naval combat simulator for devotees of the "big giui" era.
RAW Entertainment (the initials stand for "roleplaving", "adventure", and "wargames") is a new publisher which has taken over the distribution of several war and strategy games from smaller organizations where thev may not have been able to get the exposure they deserved.
Action Stations! (AS) comes with two floppies full of program and data, and a dauntingly thick manual. It requires a 1 Mli Amiga and will install on a hard drive, although it plavs quite satisfactorily from floppies. The distribution disks are not copy-protected, bu S a manual-based protection scheme is u sed which annoyingly requires a great deal of line counting and attention to letter case. AS can be played either human vs. computer or human vs. human; modem play is not supported.
Action Stations! Is a simulator for naval surface warfare for the post-World War I through wwn era. Tire "surface" must be emphasized: AS deals only with ship-to-ship combat using guns and torpedoes. This is less limiting than it might seem. WWTI furnishes many interesting examples of surface-only actions (remember the Hood and the Bismarck?), and it comes with thirty scenarios selected from the Pacific, Atlantic, and Mediterranean theaters of the War.
Action Stations! Is for pu r i sts.
There is no chrome at all. The one graphicalelementis the Battle Plot and even that will appeal only to ascetics. The symbols, derived from the U.S. Navy's Naval Tactical Data System, are meant to convey a maximum of information with a minimum of clutter. The Battle Plot,however, isa functional as it is stark. The plot can be magnified, compressed, or shifted in any direction desired for the situation at hand. The rest of the interface is black and white text, plain and functional. There are a few awkward characteristics for instance, ship information screens return one automatically to
the main screen when i! Would be more convenient to remain and peruse data on other ships but generally, interaction is quick, easy, and can be done almost completely with the mouse.
All the effort in AS has gone into trying to make the program an accurate simulation, particularly with respect to the problems and decisions a fleet commander has to face. In the role of fleet commander, the player must decide on disposition of forces, including course and speed for ail individual ships and or formations of ships, based on limited information. The program uses an elaborate visibility model to determine what can be seen of the enemy, and the Battle Plot maintains the "fog of war" generated by this model. For instance, if contact with a enemy ship is lost and then
regained, the ship will disappear from the plot and then reappear with a different ID number, reproducing the confusion likely in a real battle. Beyond deployment of forces, the player must make decisions on fire control (AS simulates the "director fire" system used in warships of theera),assigninggunnery targets, opening and ceasing fire, launching torpedoes, use of spotlights and starsheilsin nightactions, and damagecontrol. To compou n d t lie commander's headaches, gunnery and fire effects model numerous factors including timeof day, wind, and sea condition. The program also takes
account of national characteristics. For instance, the U.S.'s horrible torpedo reliability record A MAZING COM PUTING in the early years of the War, and its superior damage control expertise are reflected in the combat model.
Supporting all this is a massive data base covering all major ship types of destroyer size or larger from the U. S., U. K., France, Ttaly, Germany, and the Soviet Union during the historical period covered. Even types which existed only on paper, such as the U. S.'s Montana-class super-battleships, are represented.
Great efforts have also been made to ensure long-term value.
Aside from the random factors which can be introduced upon starting one of the scenarios provided, both a scenario editor builder, and a scenario generator, which automatically constructs scenarios according to broad parameters supplied by the player, are included.
A ferocious-appearing manual is a pussycat upon inspection. A great deal of the bulk turns out to be a thorough discussion of internal features of the game and listings of data. Another chunk is taken up by a discussion of tactics which should be useful to all but naval officers and the most experienced of armchair admirals. The actual instructions on game functions are clear, concise, and well- organized, and 1 commend RAW for the high quality of the manual.
If AS has a weak point, it's speed. Combat with large fleets can become irritatingly slow, and Battle Plot screen redraws stretch out into coffee breaks. Like other recent military simulations, such as Harpoon and Universal Military Simulator II, AS simply seems to have reached the limits of the 68000 CPU used in most Amigas, It should be a lot more pleasant to play on A3000s or machines with 32-bit accelerators.
AS is not for everyone. Those looking for a straightforward and relatively undemanding strategy game will do better elsewhere.
Those enthusiasts demanding a realistic naval warfare simulation and uninterested in tinsel will find Action Stations! An exemplary product.

For instance, two gurus are sitting in a cave. One turns to the other and says, "1 came here to contemplate the futility of it all, but 1 see that it's useless." The sentence " 'is not a sentence' is not a sentence." Also demonstrates a tangled selfreference. In computing, self-reference is called recursion. A recursion is a self-referential structure in whicha function or a routine calls itself during its own
execution or performs some other form of self-reference such as modifying its own code. Recursions are powerful, but they can be tricky. In programming, it is generally safer to avoid recursions if possible, but in some cases they are convenient and useful. Arexx is capable of running recursive functions that call themselves from within the function procedure itself. An example of such a recursive function (that computes factorials) is in either of the Arexx Manuals, the one bv William Hawes, on page 35 or in System 2.U documentation by Commodore, on pages 10-68. A function call outside a
procedure may itself be recursive as we will demonstrate here.
Iteration In general, whenever you can make a function use only one "kernel" computation that starts with a "seed" estimate and feeds the result of that computation into the same computation as a new "seed," it is a candidate to become either a recursive function or a to be called recursively. When many calculations mustbeaccomplished, this method is sometimes referred to as an iterative technique, and proves useful in solving all sorts of number theoretic problems and finding solutions to systems of equations that do not yield to ordinary algebraic means. An entire branch of mathematics
called Numerical Analysis concerns itself with these iteration techniques and the theory of their operation.
Algorithms Iteration (not to be confused with the Arexx ITERATE instruction) and other mathematical computation procedures are called algorithms. You may think of an algorithm as analogous to a recipe in a cookbook. An iteration algorithm is a set of procedures for doing multiple calculations evaluating one formula over and over again until some sort of criterion is met such as convergence to one value with an arbitrary degree of accuracy. The number of calculations sometimes runs into the millions. The famous Mandelbrot Set is a map of the complex number plane showing the results of
multiple recursions of one simple formula called the Mandelbrot fractal iterated thousands or millions of times to determine only one criterion for each coordinate: Is it inside or outside of the Mandelbrot Set? Whether the value of the expression converges or not (as each new evaluation is fed into the expression as the new seed) determines whether the point is in or out.
Since convergence or not depends upon the degree of precision we choose, the fascinating boundary between "in" and "out" becomes increasingly complex and "lacy" as we magnify the area of interest. In our example program, we will perform an algorithm until the result is an integer, a much simpler concept.
Computer Proofs With a computer, you may find solutions that are difficult or even impossible to obtain otherwise. If the solution is involved in a proof of a theorem, it is called a computer proof, and usually sneered at by pure mathematicians. Mathematicians also call such proofs ''brute force solutions," and they may have a point, Although computer proofs are not usually elegant or even ingenious, they do find answers and therefore have a practical side to them. Here is a famous number theoretic brain teaser that yields its answer readilv to an Arexx computer proof.
The Coconut Problem There are four sailors shipwrecked on an island. The island has a large grove of coconut palms which provides coconuts for the sai lors.
One day a typhoon sweeps tire island and although the sailors survive by hiding in caves, the grove (their only food source) is destroyed, but a number of coconuts are left littering the ground. The sailors collect them into a large pile, and agree to divide them equally the next day as it is now dusk.
Each sailor happens to be both dishonest and greedy. During the night, the first sailor wakes up and hatches a selfish scheme. In the moonlight, he sneaks over to the pile without waking his mates, and counts the coconuts and finds that thei r mi mber can be evenly divided into four equal piles with one coconut left over which he throws to a nearby monkey. He hides one of the four piles for himself as a hedge against starving before his three mates, groups the remaining three piles into one, and sneaks back to bed and sleeps.
As you may have guessed (mathematics isn't much on plot twists), the other three sailors do exactly the same thing: They find the remaining pile may be evenly divided into four parts with one coconut left over, which they throw to the monkey. Then they hide one of the four piles for themselves and regroup the other three piles into one and go back to bed. In the morning, since all four are guilty as sin. They pretend not to notice the much diminished pile of coconuts, but once again they find that the pile may be evenly divided into four equal piles with one coconut left over which thov throw
to the monkey (who ends up with five coconuts).
What is the minimum number of coconuts that must have been in the original pile last night?
An Ideal Candidate for Recursion This tricky little problem is ideal to demonstrate recursion in Arexx, because it does the same thing five times: subtract one; divide by four; multiply by three. However, it cannot be readily solved by ordinary algebraic means, because it has only one equation and an infinite set of unknown quantities, only oneof which has the minimum value.
If N represents the original number, then the first sailor leaves a pile containing 3*[(N-1 ) 4| coconuts. The next sailor uses the value of this expression as his N and so on. By means of Arexx we can find the answer by brute force if we start with a seed n equal to the integer 1 (coconuts are a code word for integers or whole numbers). We then try' the kernel computation above as a recursion formula nested five deep.
At the end, we test if the result is an integer or not. If it is, we stop and report that we have found N, the minimum number of coconuts, and if not, we increment n to the next integer and try again. We've just written the narrative form of our required Arexx code, so we can start programming right away.
* Coconut.rexx The coconut problem * n=l * Start with integer 1 * DO FOREVER num=fun( £un fun (fun( fur. In)))) I * THE RECURSIVE CALL * IF DATATYPE(num.whole) THEN IX) * Test for whole number V SAY 'The number 'n 'is valid. It is the minimum.1 EXIT 0 END n=n*l END * THE INTERNAL FUNCTION * fun: PROCEDURE ARG i i=i-1 I* Throw one to the monkey * i = i 4 ' Divide into .1 equal piles * i=3*i * Group the other 3 piles * RETURN i The program is very simple. We use a DO FOREVER loop with only one way to exit, when we satisfy the DATATYPEQ function with a whole number n (an integer).
This would be dangerous if we never reached a solution!
If you ever get stuck in an endless loop, to stop all Arexx activity in the system, open another shell, and at the prompt enter: Hi (for Halt Interrupt) and all Arexx programs will stop, DATATYPEQ is very useful to check strings for UPPER or miXed case, alphanumeric data, numbers of various sorts, valid Arexx symbols, and more. The manual reference is Hawes, page 56, or Commodore, pages 10-101. This is an important function to know and a little study will pay off.
The Central Recursion Our recursion is a five-deep nest of calls to the function 'fun,' an internal procedure. The only thing different here from usual function calls is that (he recursive call does not assign a value to num until the internal function 'fun' has been called five times by the nested assignment expression, each time feeding the previous result into the function as its new argument. After five iterations of the call, if die value of num satisfies the DATATYPEQ 'whole' then we exit and SAY the message. Otherwise we increment our n guess and do it all over again.
See if you can succeed in making 'fun' itself recursive. You will soon run into trouble, as it modifies its argument i each time through, and any attempt to keep track of five iterations will confrontyou with a problem in computing called self-modification. Any attempt on your part to implement a loop to count from 1 to 5 wi thin 'fun' will be a part of any recursivecallsto'fun'nndyou will soon get intodeepguacamole.
This is why you must be very careful with recursions, should you use them. Run this coconut.rexx program from a shell and in a little while you will know the answer. If you were to prove this result in a more rigorous mathema tical sense, you must expect to spend a lot more time!

Norcross, GA 30093 range of sound and then instructing the program to digitally create the echo. This is an inexpensive way to improve the sound of your instruments.
Once you have a satisfactory recording, you should trim any dead time at the start or end of the sample. Dead time at the start will cause a slight delay before the Dealing with Hum Since Amigas ore frequently used in video setups, hum can often be a problem when digitizing audio. Hum typically m anif ests itselfasaloud.low pitched noise. The usual cause is two different sample plays; dead time atthe end wastes memory. Visual sample ed iting makes iteasy to trim blank sections away from a sa mple. Once you have a "finished" sample, nothing more needs to be done to use it as a sound effect or
play it by itself.
If you want to use it as an instrument in other music programs, however, you will need to save it in IFForSONIXinstrument format. The way So do this varies with different software, but typically involves tuning the wave- grounds in a system, with a cable TV hookup the most frequent culprit. There are three generic solutions to hum problems. The first is to disconnect cable TV or other video cables while digitizing. This wili frequently eliminate the problem. You can reconnect the cables once you' re done digitizing.
Asecondsolutionisto isolate form so it plays at the proper pitch and then "resampling" it before saving. Most software can create fiveoctavelFF instruments from a single digitized sample. Some programs can use the detail found in higher sampling rates to create better quality instruments without using extra memory.
Looping offers another way to save memory by stretching a short sample over a long duration by repeating the looped section over and over. This is good for sounds like organs, which don’t change much over time. The challenge is to find good loop points that don't cause pops or dicks when repeating. One hint is to find a part of the sample that doesn't change much and try to set loop points there.Sampleedit- ing software can find a loop point automatically or can locate "zero crossings" ideal for looping. The IFF format limits the possible loop points, so it isn't always possible to find a
"clickless" loop. If you have trouble, one fix is to cut a small amount from the beginning of the sample and then try to find new loop points. You may have to try several times before you get a good loop. Once the sample is looped properly, vou can save it as an IFF instrument.

Anotherapplication involves sampling a background section and playing it over and over again.
This works especially well for drum and horn parts, where there are several instruments playing at once. You can sample the complete pattern and then play it using one Amiga voice, leaving three voices to play melodies over the background part. The only trick the cable signal from the computer and TV. This is done by connecting two 300 to 75 Ohm video transformers (known as baluns) back to back in line with the cable TV input. The baiuns isolate the cabie ground from the electrical ground used by the rest of the system, eliminating the hum.
Involved is to make sure the tempo is correct when record mg, because you won't be able to change it once the sample is recorded. Trim the sample so that it lasts only one measure, using looping to hear the resultsof each edit. While you can leave the loop points set when saving the sample as an IFF instrument, it is better to play the sample using repeated whole notes. Otherwise the voice may be "stolen" if the music program attempts to play more than four notes at a time, which could cause your background to drop out abruptly.
These tips should help improve the quality of vour Amiga samples. Nevertheless, there are limits to the quality available using 8-bit internal voices. If you want better sampled sounds there are two options: purchase a 12 or 16-bit audio digitizer board for your Amiga, or buy a MIDI sampler. If you own a 2000, 2500, or 3000, an add-in board may be the answer. If you own a 1000 or 500, an external MIDI sampler is your only choice. Current samplers offer 8 to 24 voices with sound quality that can rival CD players.
There are a few companies that make Amiga graphic sample editing software for most samplers.

P. O. Box 2140 Fall River, MA 02722-2140 A third solution is to
isolate the ground on the audio signal. Radio Shack sells a
"Ground Loop Eliminator" designed for use with car stereos. It
uses a transformer to electrically isolate a pair of audio
cables from the rest of the system.
This is an easy way to soive hum problems, and costs less than $ 15.

• AC* Nickelodeon's Nick Arcade A super new game-show produced
with the help of the Amiga.
By Jeff Gamble "Nick Arcade" is ihe hottest new kid’s game show from Nickelodeon. The premise is simple: Out-smart and outplay your opponent through two fast-paced levels of competition to win a chance at the bonus round. But there's a twist: You compete using the latest video games and computer technology and to win in the bonus round, you must go inside an actual video game!
Two teams of two players compete through the two rounds of play, moving "Mikey," the video game mascot from square to square on a giant animated game board. The squares conceal challenges including the "Arcade" challenge where contestants test their skills onconsumer video games forextra points and continued control of the video wall. The team with the highest points moves on to the Interactive Bonus Round where they enter an actual video game and fight off obstacles to score points and win prizes.
So what makes this show really unique?
It was produced and is played with the help of Amigas.
Nick Arcade was created and produced for Nickelodeon by James Bethea and Karim Miteff, both of whom ha ve done previous work for Nickelodeon and are long-time Amiga users. Creation of the video games, interactive environments, many of the sound effects, as well as titling and many of the video effects were done with a group of beefed-up Amigas, including a couple of CDTV units! Tire show’s creators used seven Amigas five A3000sand two A2000s and two CDTV units.
The A3000s average 2MB of chip RAM, 10MB memory and run at 25M Hz. The A3000s Right and Above right: Two of the interactive video games created with the Mandala Virtual Reality software.
Were used for most of the work. Sound effects were MIDI-generated using a MIDI set-up and a 3000. Two of the 3000s were used together to create the zoom-in views for higher quality graphics and resolution, and to ensure extremely smooth scrolling, Several of the units were used together in the large interactive animated game board to produce multiple layers of screens, again to ensure smooth scrolling and to increase the number of available colors. The Amiga 2000s have a special job and perform over and above the call of duty.
They are attached to an Ultiniatteand produce thegiant interactive games for the bonus round.
The A2000 Ultimatte combinations take full advantage of the Mandala Virtual Reality Software to create a video game environment where contestants "enter" the games and play them.
The CDTV' units are used onlv for the scoring system right now, but the production staff is looking into other possible uses of the units, taking advantage of the latest develop- ments in CDTV software and add-ons.
Other items used with the Amigas in- elude GVP's IV24 board and All In One board and the SuperGen Genlock. Some experimenting has been done with the Video Toaster, but it is not currently being used in show production.
Mr. Miteff said that Nickelodeon has grown to respect the Amiga as a professional video tool. The production team of Karim Miteff and James Bethea had looked at other platforms before deciding to stick with the Amiga. They found the Amiga produced the best quality and look without compromise. They were also very impressed with Commodore's CommodoreTxpress Gold Sendee. They mentioned that they had no problem getting down machines repaired, no niatter what the problem, in very little time.
The only portion of the show not produced at this time with the Amiga is tire Video Challenge. This is presently made up of commercial ly a vai lable video ga mes. Simply, it was easier to use the existing setups and the commercial games better fit the criteria of the game show. There is hope, however, that future seasons of Nick Arcade will see some popular Amiga titles played during this roimd of play.
Karim Miteff and James Bethea both have strong backgrounds in the useof the Amiga and apparently have succeeded in turning much of Nickelodeon’s production and engineering staffs into Amiga fans. In fact, they were able to get the Nickelodeon Production Department to become,Amiga Developers.
Mr. Bethea has a strong background in children’s television as well, having once worked with the Children's Television Workshop. Tire pair stresses that the main focus of their work was to create an entertaining game show and turn today's youth on to computers. As Mr. Miteff said, "These kids will be producing the Nick Arcades of the future." The show's prizes often include Amiga 500s and Macintosh Classic's.
One thing is for certain, the show, its prizes, creators, and their bank of Amigas will have a definite impact on the way today's kids look at computers and television.
