EDITORIAL Spring is in the air, and with it come changes at ANALOG Computing. The first, and most obvious, is a new format for the magazine. At the top of each article page, you will see a head- ing and an "icon" which tell you what category the article falls under {utilities, home applications, and so forth). The new layout of the magazine is modeled somewhat after the new Atari ST line's graphic operating system, and is de- signed to help new readers (as well as old) to quickly locate the types of arti- cles they're Interested in. We are open to your comments and suggestions about how we can further improve the new format and make AN- ALOG Computing even more useful to you. The second change is less visible but just as important as the format change. It is ANALOG Computing's entry into the telecommunications field. Over the last year or so, we at ANA- LOG Computing have been paying close attention to the area of telecommunica- tions with Atari personal computers. We have made staff members available on the CompuServe Atari Special Interest Group (SIG), in order to answer ques- tions and ask readers what they'd like to see in the magazine. In this year, we've seen the number of user-to-user messages on the SIG grow past the 94,000 mark. This growth rate is constantly increasing, with no end in sight. We've seen the tremendous power and potential of personal telecommunica- tions as authors have submitted their ar- ticles electronically and our program- mers have uploaded programs to the SIG for everyone to use. In September of last year, ANALOG Computing publisher Lee Pappas and I began discussing the possibility of start- ing up a company-sponsored electronic bulletin board system in early 1985. We didn't want an ordinary BBS (i.e., an Atari 800 with an 810 disk drive running public-domain BASIC software). Little did we know what we'd end up with. As it stands now, the ANALOG Com- puting Telecommunications System (or TCS) is based in the programmers' area of the ANALOG Computing editorial offices, with four 48K Atari 400 com- puters, tied together with custom hard- ware, interfaced with an 11-megabyte hard disk system. All the computers are connected to phone lines with Anchor Mark XII 300/1200 baud modems. Four people may use the system si- multaneously, and this number will be expanded to seven in the near future, as demand dictates. The software for the TCS was my de- partment and has been developed over the past six months, to the exclusion of virtually all my other projects (includ- ing HChess, a chess-like game in ma- chine language, which I promise will be in the pages of ANALOG Computing as soon as possible). Developing the TCS software was an education in itself, and I have to give credit to the people at Optimized Sys- tems Software, the creators of MAC/65 and the MAC/65 Toolkit. Their products have been instrumental in the develop- ment of the TCS's software, which is 100% machine language. Machine language was chosen for the TCS in order to get maximum speed, even in 1200 baud. Even with several users hacking away at their keyboards, downloading software and storing mes- sages, the TCS will zip along at fantas- tic speed. Users of terminal programs with XMODEM protocol won't have the transmission timing problems they may have experienced on systems like Com- puServe. The key to the TCS's usefulness is software and user support. We will be doing all we can to provide new pro- grams on a regular basis, and Charles Bachand and I will be on-line daily to answer your questions. If you have origi- nal programs, subroutines, editorials, etc. that other users may be interested in, and you'd like to see them on the TCS, upload them! We will reimburse you in free TCS time if we accept your material. The more programs we have, the better TCS will be. In the center of this issue, you will find a bound-in copy of the ANALOG Computing TCS user's guide. Carefully remove the staples, and you've got your ready-to-use TCS manual. I suggest you read through it before logging onto the TCS, in order to familiarize yourself with the system's operation. I hope you enjoy both the new maga- zine format and the TCS. We've put a lot of effort into both, and will be expand- ing and improving them further in the future — to keep ANALOG Computing the #1 Atari users' magazine and tele- communications system. Our thanks. Finally the staff of ANALOG Comput- ing would like to thank Mr. Edmund Miarecki, who was kind enough to pro- vide us with the Atari 520ST computer pictured on this issue's cover. D Hudson~ Chief of Programming ANALOG Computing ANALOG COMPUTING MAY 1985 /PAGE 5 READER COMMENT Disks to come. I have recently noticed that back is- sues ai-e available in magazine form. Are these same issues available on tape or disk? If so, how much per back issue? Also, how much is the Compendium on disk? Does Solid States work on the 800XL? I typed it in, but there were a lot of string/DIM errors. Jim Kelly Snellville, GA Because of the huge number of letters we receive concerning back issues on disk, we will, in the near future, offer them for sole. As far as the ANALOG Computing Compendium on disk, it is priced at $35.00, which includes only the disks. To receive the Compendium disk set, you must use the order card in the book il- self The price for the Compendium is $14.95 + $2.00 shipping and handling. And, yes. Solid States runs on (he 800XL. It sounds as though you have a bad BASIC. —Ed. Keyboard pals. It is now, al the time of this writing, a miserable October day in tlie north of England. I have recently acquired the most recent issue of ANALOG Comput- ing on these shores, which was a joyous moment, indeed! Let me explain. Here in Britain, we simply do not have magazines that sup- port the Atari (nor any machine) tire way ANALOG Computing does. On top of that, the most recent issue available is the April issue! A sad state of affairs, 1 know, but at least we are getting the magazine — thank goodness. But now, on to my real reason for writ- ing. . .1 am aiming to set up some kind of international "keyboard pal" service. Basically, the object is to "pair" Atari en- thusiasts in (to begin with) America and Britain. If it is at all possible, I would be grate- ful if you could let your readers know this hopeful "service" is aimed primar- ily at them. Anyone from the States who is interested should send full details of themselves, plus how often they would like to "write" — in fact, as many details as they can think of, on disk or cassette (or paper), to me at this address: Paul Critchlow 29 Tudor Road Tranmere Birkenhead IVlerseyside L42 5PH England No charge will be made, but (there's al- ways a but!) two I.R.C.s flnternationaJ Repiy Coupons — available at your post office) will be warmly received and will, no doubt, hasten a reply. Young or old, novice or expert — any- body is welcome. If this service is suc- cessful, I promise to keep ANvVLOG Computing informed as to the progress! Yours in anticipation, Paul Critchlow Planetary Defense with Touch Tablet. For all the readers who purchased the Atari Touch Tablet , instead of the Koala Pad, I thought you'd enjoy this modii'i- cation to an earlier ANALOG Comput- ing game. This BASIC program will install a patch in (the assembled version of) Plan- etary Defense (issue 17), to allow it to work with either the Touch Tablet or a joystick. This modification will only allow fir- ing from the lei't button. If you would rather fire from the right, substitute 125 for 124 in I^ino (JO. This program creates a modified version (PLANETT.EXE) of the original (PLANET.EXE). Best regards, Forrest A. Blood IV Willingboro, NJ 10 GRAPHICS e:DIM 0LD$(15} ,MEHS(15):?

First, I would like to congratulate you on a "first class" magazine. It's really great! Second, I really enjoyed the IVlagic Palette program, but I have made it even belter. Graphics modes 9 and 11 are good, but it you enter or change the program to graphics mode .30 or 31, you only get half a screen, but the pictures are much better. PAGE 6 / MAY 1985 ANALOG COMPUTING If I am correct, graphics modes 14 (full screen) and 15 (full screen) are available only on the new XL computers (600XL must have memory expansion).

Keep up the good work! Jim Kelly Snellville, GA Mating your VCR with an Atari computer. The current popularity of VCRs makes for an interesting equipment marriage with a computer. I use my Atari 800XL with a Quasar (VHS) Video Cassette Recorder You'll need a video monitor cable — which can be obtained from Comstar, 5120 Hol- lister Avenue, Santa Barbara, CA 93105 (805-964-4660); called a Data Spec, it is model CLC-VEC-5, at a cost of $6. There are three connectors on this unit. Plug the 5-pin metal connector in- to the monitor port at the back of your 800XL. Then plug the red-coded lead into your VCR video input on the back of the VCR, and the yellow-coded lead into the audio input (also on the back of the VCR). Turn on your VCR, fire up your computer system, and away we go! Okay, but what can you do with this hookup? I use it in my work at school, to create graphs, pie charts and statisti- cal information at home (with B/Graph) , and then take the video tape to class to demonstrate procedures for my students. It sure beats setting up all the computer components, having to find the correct wires and enough elec- trical outlets, etc. Other uses — you've probably thought of some already. Presentation of your computer artwork in a slide show video format is exciting. For the animation buffs, you're not limited to a few min- utes but can piece together a longer seg- ment, perhaps a full length movie! The Atari's full sound and color come across on the video tapes. If you have more time (and money), you can mix computer material with video camera material, to produce some interesting programs. If you have sound dubbing capability, music and voice can be added to your tapes. Lead-in and end credits are open to your artistic talents. Moving letters, different colors, sizes and designs are all possible. I use the Displaymaker pro- gram for many of these purposes. Drawbacks or limitations — the Atari 400 does not work with the video cas- sette recorder (at least, not easily), nor with a monitor Since I also have two 400s (I'm a member of the $99 club), 400 owners have my sympathy.

(( THE IMPOSSIBLE"! rs> they claimed! A ATARI Backup almost any disk currently available (even heavily protected programs) with an UNMODIFIED disk drive! $149.95 Works with ANY disk drive! PURPOSE: The "IMPOSSIBLE" was developed in response to the estimated half million disk drive users that own a drive other than the Atari 810 (Indus Per- com, Trak, Rana, Astro, etc.) that wish to BACK UP their protected software. Due to a radically new technology developed by Computer Software Ser- vices, modification to your disk drive has been eliminated! The advantages ore obvious! Drive warranties are not vioiated, the chance accidental damage has been eliminated, etc., etc. OPERATION: The "IMPOSSIBLE"! consists of a disk program (unprotected so you can make as many backups as you wish) and o 4K STATIC RAM pack which is inserted intoyour computer (no soldering!)The "IMPOSSIBLE"! will read your program disk and then re-write it In on unprotected format! You may make additional backup copies using a sector copier or even regular DOS! Because your backup copy no longer has BAD SECTORSor EXOTIC FORMATS, the program data can now be manipulated into DOS compatable files (even double density!), transfered to cassette, etc. (with the aid of our Soteiiite programs!)

NOT A PIRATING TOOL: We at C.S.S. did not design The "IMPOSSIBLE"! to put Software Manufactures out-of-business overnight! Nearly oil of our products have been "ripped-off" by industry parasite who have little or no abiiit/ to develop a product of their own so we con sympathize with their dilemma. All C.S.S. products have built-in safe guards which prohibit their use for flagrant pirating. The "IMPOSSIBLE"! is no exception! While The "IMPOSSIBLE"! back- up the most heavily protected programs, it also checks to see that the 4K STATIC RAM pock is installed before allowing the backup copy to execute!

I know you've got BASIC AUTO- RUN.SYS filemakers coming out of your ears. But this one's different! Sure, sure . . . that's what they all say. No, really! Before you string me up, give a listen. This one is very short (100 bytes or so) and it'll autoboot any BASIC program using any filename. But it does more than that. For one thing, it won't leave you looking at any READY prompts or blank screens while the program loads. It prints LOADING then the filename to let you know just what's happening. It'll also accept a filename up to twenty characters long. So, if you type your actual filename and leave a space (or any illegal filename character), you can have it print LOADING SNAKE[?!) or, perhaps. LOADING MENU, PLEASE WAIT. It's a very short program to key in (should only take ten minutes or so), and if you check the trailing REMs, you can see that you have a few alternatives. Designed primarily for DOS 2.0, it works with any DOS that recognizes AUTORUN.SYS files. Just type it in (don't change anything) and follow the directions on the screen when you run it. It cre- ates the AUTORUN.SYS file in about four seconds, then you're ready to go! Try it — you might like it. May all your boots be shining! □ BASIC listing. 5 REH D:RUNAUT0.BA5iC 6 REM by CHET WALTERS tcJ 84 7 REM 10 GRAPHICS ; 5C=PEEK C88} *256*PEEK <83> : DIM AS {213 .

Griffin, M.D. In ANALOG Computing's issue 24, I reviewed an exceptional educational game from Sprout Software, called Tonk in the I.and of Buddy-Bots. Now, two ad- dilional programs are available in the TinkTonk series of educational software designed for children of ages four to eight years. While maintaining the same high level of quality, these new games have an even greater educational thrust. TINK'S ADVENTURE Sprout Software MINDSCAPE, INC. 3444 Dundee Road Northbrook, IL 60062 (314) 480-7667 48K Disk $24.95 Tink is the trusty leader of the Tink- Tonks and is about to embark on an ad- venture. As Tink ai-rives on foot at Tink- Tonk Lake, he has the choice of continu- ing the adventure by helicopter or boat. Having selected the means of transpor- tation, one is given the chance to play a game or begin the adventure. At various junctiu'es, similar options appeal', providing Uie opportunity to play one of seven games included in the ad- venture. Most of tliese games have educa- tional value, but two of them, l^ilot l3oat and fly Helicopter, are included jusi for f u n . Using the keyboard, one may pilot the boat ai'ound the islands in TinkTonk Lake or fly the chopper through the sky in front and back of islands, clouds and even stars. These activities have no bear- ing on the course of the adventure, but simply provide a pleasant little interlude. The other five games are designed to help children learn ABC order and to familiarize them with the computer key- board. In Get Gas, four consecutive let- ters of the alphabet are displayed with a blank at the begimiing or the end of the sequence, depending on the option one has chosen. The level of difficulty may be selected as hai'd, where ten correct answers are required to fill the helicopter's tank. This task is made easier with a display of the complete alphabet at the bottom of the screen. A harder level requires twenty correct answers witliout the benefit of the PAGE 14/ MAY 1985 alphabet display. There is no time limit. and incorrect answers ai'e ignored and incur no penalty. This game provides an opportiuiity lor the young child to arrive at an answer, whether from the screen display or the time-honored "mental recittition," whik; exploring the keyboard without the pres- sure of time or the fear' of being wrong. The development of speed and accm-acy in the leai-ning process is important, but before this can be achieved, the basic in- formation must be as,similated without stress. hi Go fishing, children get to know the computer keyboard. The keyboai'cl is di- vided into four designated areas: the lop row of numbers, and the left, center and right portions of the remaining keyboard area. After a specific area is chosen, or the entire keyboard, if desired, the size of the fish is selected — from one to five charac- ters long, finally, one of three speeds is chosen, determining how fast the fish will swim. As tlie combinations of characters pass beneath the boat, they are reeled in by reproducing them exactly as shown, be- ANALOG COMPUTING Educational Programs Review LR>c
