Do You Own as 2ZoeoR= Or Are You Getting Ones? And Are You Interested Im Machine Code Programming?

Undoubtedly you would like to own a nice machine code loader, and a simple disassembler, and a hex/decimal;decimal/hex converter. Then you could easily follow and learn from Dick Scoville’s machine language tutorial which starts in this issue. Such utility programs as we have mentioned above usually cost %9.95 and up. BUT for TSUG receivers, | Dick will provide all the above programs on a good tape for only $5.00 (s+h included)--a real bargain. Please send your order today to Dick Scoville, 2313 W. Club, Durham, NC 27705. If you purchase this tape,we will consider your purchase to be a show of interest and confidence in TSUG and will not soon drop you from our newsletter mailing list. This is important if you have been getting our newsletter FREE NC. As you will find out inside, we are ready to clean house (¢!') and trim our mailing list toa more manageable number of interested people. Don’t cut yourself off from TSUG nor from machine code.

NEW OLD PRODUCTS FRODUCTS NEWS OFFERS

By Billi Roberts

GREAT NEWS! TIMEX SINCLAR USER magazine does NOT appear to be dead, as we last reported, but it may be changing colors! We hope to be hearing from them soon: though in the newsletter press there is some skepticism about this magazine’s reappearance in its original form, now that TIMEX is joined by SYNC who is out of publication. Write to Timex Sinclair User, P.0. Box 325, Mt. Morris, IL 61054 or call 1-B00- 435-0715 if you"d like to know more about your Timex Sinclair User

subscription.

TIMEX has had 2050 mademe manufactured, almost released them, and then decided not to de so at the last moment. Doug Dewey saw one in operation in the TIMEX Atlanta office in early February and thought it looked fine. The packaging and unit were all finished but the software cassette and documentation were preproduction versions. We understand there were a few minor problems in the modem and that a software company is still owed some money for their part of the software package. And the latest is that the modems have 611 been shipped back to Anchor, the manufacturing company.

mast : . RA. THE BEST DEAL ON A MODEM SEEMS TO BE BYTE-BACK IN SOUTH CAROLIN

BYTE-BACK, Rt. 3, Box 147, Brodie Rd., Leesville, SC 29070 (803) 532~- 3812. Byte-Back has the best software and has models ..for both TS2X -and

2068 computers.

ee — ah aes it Rigas! oa

Bernard V. Gerber of TIMENSA SOFTWARE, 3707 Downey Dale ODr., Randalistown, MD 21133 sent a nice program called DO-CALC which we begin to review in this issue. His program is illustrative of the great strength of the TSZX market and is available for $16.00 postpaid. Bernard also has some TSi000 computers available without manuals for $25.00 postpaid.

T.S.U.6. member Bill Kegelmeyer (7510 Overbrook Dr., Fayetteville, NC 28303 (919)864-4488)of D & L COMPUTERS has become the area dealer for A & J MICRO DRIVE. I am all for it! I have a Stringy Floppy and I really can give it my highest recomendation. Let me give you a few of the really nice specs on the Stringy Floppy. The SF has a data transfer rate of 10.4K BAUD. That’s over thirty times faster than 4 cassette! The wafer tapes are i.6" by 2.7" by 0.2" and weigh, typically, 9.4 grams. These are high quality tapes: the base is mylar with a chromium dioxide. magnetic coating. The maxium tape length is 50 feet (about 70k of data) doun to a minimum of S feet. Tape speed across the head is 25.4 cm/sec. One new feature that is included in this version of the SF is a wafer directory. This is a much needed improvement as you can store up toa 127 files per tape. If several people in the group are interested, we can make an order and possibly get a discount. Older Exatron Stringy Floppies will run on this new hardware version.

K.D.V.H.E Publishers, P.O. Box 6788, Chicago, Illinois 60680, has Several nice sets of Statistics books and cassettes for the 16K TSZX. The price is either $15.00 or $17.00. The program: seem very complete. Each set contains:

Independent groups t-test to compare two means, F-vest to compare two independent variances:

‘Correlated measures t-test, t-test to compare two correlated

variances, Pearson product-moment correlation coefficient}

Independent groups one-way analysis of variance (completely randomized k group design)s

Randomized block analysis of variance (two-way analysis of variance): calculates two F-ratios, one for treatments and one for blocks (subjects) § . . .

Independent groups two-way analysis of variance (completely randomized Factor val d by K Gesign?: Calculates F-ratios for Factors Ay _B, _and

paar ers eo 52 Sethe ee date ae ie on wee River ose J

Gplit-plot Factocwat ceacnay analysis of variance: calculates F-ratios for A, B, and ABs

Randomized block factorial two-factor analysis of variance: calcuteres F-ratios for Blocks, A; B, and ABS

Independent groups three-way analysis of variance: av ehiatee F-ratios for €, B, C, AB, AC, BC, and ABC;

Split-plot factorial analysis of variance: calculates F-ratios for A, B, C, AB, AC, BC, and ABC.

Book 1 is for small data sets with two or fewer factors. Book 2 is for large data sets and i to 3 factors. Book 3 is for medium data sets and up to 3 factors. Book 4 is for medium data sets and 2 or fewer factors. If you do a lot of data crunching maybe one of these programs will fit your need.

SUPER LIBRARY, P. G. Box 27125, Union Park, FL. 32867, will rent you programs for the TSZX. You rent the program for 30% of the retail value. If you decide to keep the program you send the balancte of the retail value, otherwise you return the program. There is also a $25. oo annual membership fee.

ZEBRA SYSTEMS Inc., 78-06 Jamaica Ave., Woodhaven. NY 11421, ts having a SO% discount sale on selected items. This includes Timex RAM packs, Zircon video command joysticks and some sofeware from Softsync and Timex. The prices are good till April 15, 1784. This maybe your best chance to buy that program you have been wanting for ages but cid NOT have the bucks for. They have also sent the group a list of patches that allow their TS1000 joystick to work with some of the more popular games. The patches may also provide. some insight for thase who nave 4 homebrew joystick set up. The patches were handed out at our last meeting, so if you need one, give Doug Dewey a call. The prices for the RAM packs are: S19.95/1, $19.00/2, $15.00/5 ard up. we

TRADE-A-COMP, TRADE-A-DISK, FP. 0. Box 671, Bethel Park, Pa 15102, has an interesting newsletter. It is for people who want to buy, sell, or trade new or used computer software or hardware. subscription is: $18.00/year or %10.00/6months. The minimum number of words per ad is 20. It cost $0.15 per word per issue.

pa TECHNOLOSY, FP. 0. Box 340128, Tampa FL 33694, has a really nice eal. They are offering their 64K RAM pack as a kit (without chips).

The price is 20.00. If you have questi or just write. Sestions you can call (81S) 961-2595

ALAN PATTISON, 3422 French Loop NW, Olympia, WA 98502, has software for both the TSZX and the TI 99/4A. A sampling for the TSZX reads like this: Money Manager, Bingo, Weaving Patterns (I like this one: you design your own weaving pattern and when you are finished the program displays what the finial product will look like), Payroll, Inventory (150 items), Stats, Equipment Cost, Breakeven, Space Analysis, Mail Order, etc. These are very reasonable in price at only #8.00 or $9.00, And Alan was kind enough to send two of these programs ‘for reviews Bingo and Personnel Selector.

MULE ELECTRONICS, 444 Lincoln Blvd. Dept 310, Venice, CA 90291 (213) 452-1205, has avery nice set of keytops for your homemade keyboard. They also have plans to produce a keyboard kit for $49.95 with a 57 key keyboard (40 regular keys and 17 shifted or dedicated funtion keys). Their keytops are extremely well made, top quality vinyl: black letters, red shifted keys, blue shifted functions, ail for $11.95. And for $5.00 more you get all the shifted keys and 0-9 plus "Repeat" for your numeric keypad. For some reason, Mule ships their excellent product at times that seem to be determined by powers far superior to those that govern the Post Office. They say that they ship twice a months but you may have to wait up to two months for this fine product. Doug Dewey and Harvin Sauls both claim that these stick on keytops are well worth the wait.

Howard Loboda af ROMPAK, 8206 Blackburn Aves, Los Angeles, CA 90048 writes that Rompak fully intends to support the TSZX computers through 1984. His Rompak. is selling very well. It’s a 4K/8K EPROM READ Board with a ZIF socket and extender (ZIF=Zero Insertion Force). He is marketing ZX PRO/FILE, QUICKLOAD and ROMPAK’s own software: he had earlier thought of expanding and licensing software but received so much really good software that he thought it better to stick with what they already had for now. The ROMPAK kit is not being marketed but the assembled version with ZIF socket and extender IS at $16.95 + $2.50 sth. Howard PORT SER A ERNE Se copy after he restocks. - rea Don Barnard of TIMEX/SINCLAIR TRAINING SERVICE, P.O. Box i3214, Red Bank, TN 37415 (615)877-6328 from 1 to 6 pm, has sent along their most recent issue of the T.&.T.1.S. software product tape as well as review copy/gift .of a STAR TREK game--an interesting adventure game (with static graphics displays) that Don includes with orders for 5 or more programs. His T.S.7.1.S. product tape is $2.00 and he will update it with your order. The tape is well worth purchasing if you want to know what is available for the 2068. Don is a very informative conversationalist if you’1]1 give him a call.

KNIGHTED COMPUTERS, 707 Highland St., Fulton, NY 13069 has the 2068 and 2040 for $189.95, Bob Fingerle’s TEXTWRITER 2000 and 2000+ wordprocessors for the 2068 (one for the 2040, the 2000+ for a full sized parallel printer) at $17.95 and 24.95 each, the AERCO Centronics Parallel Printer Interfae for the 2068 (with software) for $64.95, the Panasonic DT1300D Color, Hi Res (switchable composite and RGB) for $397.00. They say to add 3% for s&h. Doug Dewey tried to cali them but they haven't got a phone...They did advertize in the most recent issue of SYNC (the Last of SYNC?).

“GARY SMITH of HAWG WILD SOFTWARE, P.0. Box 7668, Little Rock, AR 72217, (¢S01)227-7817 (MCI I/D: 116-5247) is as proud as ever to be supporting the T/S customer base. Remember that Gary features the “Ham Hacker" series as well as XFORTH and the XFORTH XCHANGE newsletter that we regularly feature in our pages.

See THOMAS B. WOODS* ad and letter later in the newsletter. He’s going strong as usual and promises to visit with his family this spring on his way south. Remeaber that his PRO/FILE is available for the ROMPAK board for the ZXTS._

BIOCAL SOFTWARE, 167 Wilson Stret, Petaluma, CA 94952 (707)763-4348 have a number of great games cassettes or CAI/ESF (Stringy Floppy) wafers at either $10.00/cassette or €15.00/wafer:Life, Rebound, Bomber, Backgammon (which they have included for review along with ZBODA, a machine code monitor disassembler), Blackjack/Bar Dice, Gin Rummy/Solitaire, Wim/TacTix, Meelborn/Riverside, Steck Market and Checkbook. These are good prices for top quality software.

Remember MAG-RAK and DELPHIC ENTERPRISES, two of our advertisers this issue. The MAG-RAK is a nicely made preduct and an extremely handy ‘one, too. It is also available with a non-glare clear cover for $39.95 (the non-glare cover can be purchased separately for $15.00). And DELPHIC ENTERPRISES’ PROGRAMMER’S UTILITY EPROM will operate on lots of different boards and contains just the right combination of utilities at a very reasonable price.

In addition to SYNTAX, RD 2 Box 457, Harvard, MA O1451, at $29.00 for 12 to 15 issues here are three more excellent and important newsletters: TS USER, P.0.Box 155, Vicksburg, MI 49097 is $26.95 for 12 issues and will feature a list of bargain basement prices in upcoming issues;Ralph Coletti’s SINCLAIR/TIMEX SOUTHEAST REGIONAL NEWSLETTER has lots of hardware information (info from England, too) and projects and comes out in-6 issues/year for $12.00 or $2.00 per issue; and Alex Burr, KSXY, and *Bo” Barry’s, W4GHV/5, @ZX NEWSLETTER for ham radio and TSZX computer operators--but really of interest to a lot wider audience--is available for $12.00 per year from @2ZX, 2025 O’Donnell ODr., Las Cruces, NM 88001.

At the February meeting, Clark Beall became the first Treasurer of the Society. ae:

Ken Boone gave a very interesting demonstration of "Junior", his — roving homebrew robot. The robot really perked interest with the remote control and the ability to “learn”. -A task for the hand; capable of vertical and rotational movement, and the robot movements ‘were repeated in the learn mode with remarkable precision. The robot, was assembled primarily from scrap parts, hand worked sheet metal,

and a vintage 6800 microprocessor kit. Our thanks to Ken for bringing, in “Junior".

Weare EP Tee ears THE INVASION OF RUSSIA, JULY 19741

RATED A + Review by Robert Cromartie

I tried two versions of this war atrategy game by Mark Steuber, one @ 16K TS 10@0/ZX81 version and one for the 2868. In this simula- tion of the Nazi invasion of Russia, you control the German forces with the object of capturing and holding Moscow for four consecutive game turns. Your army consists of divisions and brigades of Panzers and infantry, with varying attacking and defending power and range of movement. You are opposed by the more numerous but generally weaker Russian forces. Each turn consists of four distinct phases. In the first, you control the movement of the German forces. Each of your units blinks to indicate its turn to move, which you direct uGing the cursor control keys. If you want to stop a unit's movement before the maximum alloted for it, you use the 9 key. An unfortunate feature of this part of the game is that the pieces move in a certain order which is predetermined by the computer and you carmot defer the movement of a piece until later in your turn--this often results in units getting stuck behind their own men who have not yet had their turn to move. After the first phase, the computer conducts the German attack phase, the Russian movement phase and the Russian attack phase and adds any reinforcements. The first few turns tend to maké you overconfident as the German units roll through the Russians with ease, but you soon realize that this is only an illusion as reinforcements bolster the defenders ranks and progress becomes much slower. The Germans must also cope with weather, morale and supply factors as the invasion drags on.

It is probably not fair to compare the black and white version with the one for the 2868, so I won't, except to note two things about the ZX81 game: it uses fast mode, so the screen goes totally blank during phases two, three and four, which can take up to five minutes for the computer to complete. Also, the player must be sure not to move over other units (if you do, they disappear from the screen until the next turn)...in the color version, the computer won't allow illegal moves. In both versions the various units are represented by inverse letters and are eccasionally difficult to distiguish, but this is not a Major problem. ; renee bth gaa no i don't have anything to compare ~~ this game to, but once I overcame some initial confusion and frustration about the mechanics of the game, I must admit I got hooked. I improved each time I played and, in my fourth game, I managed to occupy Moscow for three consecutive turns. Much to fry surprise this game suddenly ended with the message “You lose... Russian forces entered Germany”, a pitfall not mentioned anywhere in the rules. ,

My overall impression is of a fine product that hasn’t quite been finished. A few relatively easy enhancements could make this game truly great. Aside from the movement problem mentioned above, the attack phase should allow for the Player to chose which units to attack and the order of the attack. During the attack phase, the computer choses @ random number, which is combined with the power of the units to determine the result of ar attack. These numbers should be displayed on the screen so the Player can better tell what is happening. The documentation is Poorly written and not complete, but the patient reader will find the information he needs. Better execution of this fine idea would make this a four star game.

The last issue of 7T.5.U.G. would not have been the same without two or three borowings--at least two of which have gotten me into a small bit of trouble. From the CATS Newsletter {(non-copyr: ghted like our own) I got. Mihaly Grell’s want ad for machine code fam: as well as Jules

Gesang’s little ad and a piece of text which begins "SUBMISSIONS for this newsletter are...."

Dunbar Aitkens wrote and was concerned about copyrights for special materials. Now that the big magazines ari’ perishing at an extraordinary rate, I suppose some of the better stuff will show up in newsletters and nowhere else and the whole issue of copyrights will become very important. I hope that we can continue 23 free and open exchange between users’ groups--without great corcern about little things and with credit to sources (Mea CulPa, again).

But if there is a need for copyrights to be establishec’, I hope it can eccur on an individual piece-by-piece basis so that ve will have no concern for borrowings from other areas--borrowings that might be better described as "sharing."

The other thing that I have received several comments about was an attempt to report fairly on The Winky Board. Well, Bill fbussell, of Winky Board fame, called and Pete Callinicos, of Colorado’s Mile High Chapter, wrote and all is fine with them and with the Winky Board which is now out in the 2068 version. I thought that was the case when I quoted from the Vancouver Newsletter source. But I gather that a small misunderstanding was so blown out of proportion that it may have affected G. Russell Electronics. I hope that we will all beware of the

power of the press and understanding of its obligation to report areas of contention.

FROM RENZL NOTES

RPNZL QUARTET.

RPNZL (Reverse Polish Notation 2x81 Language) is a fast machine code program that interprets RPNZL codes, or tokens, mucha as the ROM in the TS1000/2X81 inter- prets BASIC tokens. There are many differences in how this is, done, but mainly RPNZL is faster, more compact and more versatile.

Included in the RPNZL System Package (see page 5) are four essential programs written in RPNZL. The first is the Monitor and is laoded along with RPNZL itself within a BASIC program. Its function is to load, save and verify data to tape 12 times. faster than BASIC; plus, to let you examine, change, and print data in your computer's memory. ' The Monitor also supervises the running of other RPNZL programs.

The next two programs come together in one file on tape; they are the Editor and Compiler (EDCOM). The Editor allows you to type into the computer just like a typewriter, except a "text file" is used instead of paper. The Editor also lets you load, save, verify and print these text files.

The Compiler takes a text file prepared with the Editor and translates it into

RPNZL codes, or tokens, and stores the

code in “link files*.”

Later, a number of link files are all played back to the fourth program, called the Linker, which (appropriately) links the code together into a program.

‘Even if you're not a programmer, with the RPNZL System you can run any RPNZL programs others have written, and still take advantage of the added speed and power. R

NEW FOR THE PRO/FILE 2068: a fast versatile and efficient information storage and TS2068!! retrieval tool for the Timex 2068. A DATABASE PRO/FILE 2068 lets you manage information with your TS2068. You can

use it for logging personal memos, scheduling appointments, compiling Statistics, Cataloging inventories, indexing abstracts, recording research data, managing a mailing list, and much much more.

HIGH CAPACITY

PRO/FILE 2068 lets you store "files" or "screens" of data that contain and EFFICIENT

anything you want. Actual file length is not preset. The program has a total capacity of 28,000 characters. Each file only takes up as much space as the characters used in the file plus a few “overhead” bytes to help the program run, ‘ ;

After data is added to PRO/FILE 2068, access to the files is provided by means of a "relational! linear search". In English, this means you type in a word, symbol, or phrase that you know is in the file you want. The. program then displays every file that holds the matching word. Finding files on the basis of just one word is really just scratching the surface of PRO/FILE's capabilities, however. With this program, you tan scan your files for as many words as you like. You have a total of 32 characters inwhich to input your "search command". That command can be just one or. RY as
