rumors persist, but still no deal

Despite many persistent rumors, Timex says no group has emerged to take over their computer business. SYNTAX can find no evidence of a credible buyer even at the stage of serious negotiations — despite what you read elsewhere

SIMULUSION RELEASES 16K ZX/TS SOFTWARE

Simulusion, now located at Box 2382, La Jolla CA 92038, now offers 11 cassette packages for ZX/TS machines, including 2 with recipes for drinks and party snacks. All do home tasks or play games. Write for free catalog.

TIMEX RELEASES 2068 MANUAL

Just at press time, Timex began to deliver copies of its comprehensive technical manual for the 2068 computers. Every owner should buy this book — if you don't need it, you add to the resale value of your machine with the extensive documentation provided. Those of you trying to locate or decipher ROM routines will get much data and many hints from this manual. Major headings include: Overview, Hardware Guide, Software Guide, I/O Guide, Advanced Concepts, Known Bugs & Corrections, plus 4 appendices — one of which is the application development library. You get a reduced-size schematic with the manual, but you may order a larger one separately.

ZX/TS RAM PSEUDO DISK — 8K/64K

If you have a 64K RAM on your ZX/TS, you can recover from crashes by periodically saving your work in high memory, as a snapshot of your current 16K environment. You need a reset button (a momentary contact normally open pushbutton between edge connector pins 21A and 4B, with a 10 ohm 1/4 watt series resistor) and a short machine language routine hidden in the 8K to 16K area (where most 64K RAMs put extra memory).

You cannot, of course, use this as backup if your work in progress exceeds 16K RAM (if you don't adjust RAMTOP, this can't happen anyway). And this won't save you if you accidentally lose power (since the RAM will forget — unless it's battery backed up).

But if you're working in machine code and the system crashes, chances are good that you can retrieve your work from the last time you stored a snapshot.

Enter the program listing and RUN. Then type these numbers, pressing ENTER after each:

017 000 128 024 003 017 000 192 213

205 035 015 209 033 000 064 001 000

064 237 176 201 033 000 128 024 003

033 000 192 213 205 035 015 2 09 017

000 064 001 000 064 237 176 201

Now you can erase lines 5 and 20 and SAVE the program and array to tape. After you LOAD, start with GOTO 10.

Once you've loaded this routine, you can take snapshots of your worK. A 64K memory will hold two snapshots as well as the 16K main working memory. To take a snapshot, use:

RAND USR 8192 for snapshot #1

RAND USR 8197 for snapshot #2

To reload after a crash, or just to see what's in each snapshot memory, reset the computer (if it crashed)

and use the command:

RAND USR 8214 to load snap #1

RAND USR 8219 to load snap #2

This routine always puts you in FAST mode, since loading a snapshot made in SLOW mode while in FAST mode (or vice versa) would cause the system to crash.

These USR calls can be used inside programs, too. The same rules as for LOAD and SAVE apply: if you RAND USR 8192 inside a program, then when you RAND USR 8214, you will be right back where you were at the time of the RAND USR 8192, even RUNning.

Even if you don't have a need for crash recovery, you can store your two favorite programs in high memory snapshots and then have them instantly when you want them. You will not, of course, be able to use them in conjunction with what you were doing in the main memory.

Be sure not to load a snapshot that you never saved; the system will crash. Also, if you have 32K memory with RAM between 8K and 16K, you can use snapshot #1 but not #2.

"If only..."--r uef ul words.

"If only" I had this book two years ago... learning to program in BASIC would have been less of a struggle. I could have avoided trying to learn Sinclair BASIC from texts written for other systems.

Do you want to learn to draw flowcharts? This books explains.

Do you need a bubble sort routine? There's one on page 292. Are you curious how the ZX/TS or TS2068 memory is organized? All explained in a clearly written chapter.

This book has useful programs galore. There are exercises for you to practice on. There are games and ways to apply general programming skills to specific problems. This is a text on pro¬ gramming in BASIC, using Sinclair BASIC. Nothing is assumed; the instructions begin with how to plug in your computer.

The subtitle, The Only Book You'll Ever Need to Become an Expert at the Timex/Sinclair 1000 and 2 000. is accurate — you won't need another book in order to learn to use your T/S computer expertly.

There is no index in the book and, while the Table of Contents is detailed, it dows not truly replace the advantage of a good index.

That is my only criticism of this well done book.

ACZ General Ledger, a very reliable double entry bookkeeping and accounting system, caters to small business needs. It LOADS and SAVEs without trouble. The prompts are the best I have seen. If you follow the understandable instruc¬ tions in the detailed manual step by step, you'll have no problems.

You enter journal entries at the end of each accounting period (usually monthly) and then the computer takes over. It generates ledger entry displays and a post closing trial balance for the beginning of the next period.

This system works well for a single proprietorship or a partner¬ ship containing up to 5 partners.

In the latter case, the system accounts for each in accordance with whatever ratio of profit sharing or ownership stipulated during system set-up.

Ingeniously, each of six dif¬ ferent modules LOAD seperately; none take more than a few minutes.

A tape file module allows saving data from each module on tape.

Print-out options include entire ledger, income statement, balance sheet, and equity state¬ ment. Trial balances can be print¬ ed if you can program it in.

Once you use this package, you will never want to keep books manually again.

From: Dell Publishing Co., Inc.

Over the years I have grown cynical about books purporting to give working listings of interest¬ ing games for Sinclair computers. Often they do not work or are dull. So, merely in the hope of learning techniques for programming color, sound, and user-defined graphics, I purchased Peter Shaw's book.

Games published include very clean listings of working programs. I was struck by the originality of the games presented. Even those with the usual game plans have unique twists and amusing graphics.

I have not typed in all of the games, but those I have tried are wonderfully challenging and enter¬ taining. "Egg Savior" displays a set of golden eggs guarded by three randomly firing "lasers". A line of blue egg crates appears at the bottom of the screen, and in the middle stands a little magenta man. You must put six eggs into crates without being hit by laser fire or running into anything. Excellent sound effects combined with action and a really attractive screen form a challenging game.

This books also lists Simon Says, Blackjack, Checkers, Hangman, and eighteen other games. Other sections include "How to write better programs" plus an excellent glossary of computer terms and an exensive annotated bibliography.

Anyone who wants to play games on his 2068 couldn't get more for his money than by buying this book.

DEAR EDITOR:

Everyone knows that Sinclair Timex computers are dead now that Timex quit, right?

Well, I'm always the last to get the word, darn it! In May, I completed my "Super JO1000", a TS1000 upgraded to full color, 124K system with EPROM programming,

EPROM read, and Centronics parallel printer interface. ("JO" stands for John Oliger, who produces a series of excellent kits for upgrading the ZX/TS.)

My Super JO1000 makes an Apple look like a lemon. But, since Timex quit, I guess I'll have to shuck it. And I just ordered a new 2050 modem, too! Yes, the 2050 modem is now on the market. E. Arthur Brown Co. [3404 Pawnee Dr., Alexandria MN 56308 612/762-8847] has them. It doesn't carry the Timex name, but it is the same one they "promised", and it works with all Sinclair/Timex models. At $119.95, I thought it could get me into "telephone computing".

And I've just finished putting together two "user cartridge kits" for my TS2068. Each has 16K capa¬ city for EPROM software. These new kits and the kits that form the Super JO1000 are produced by John Oliger [11601 Widbey Dr., Cumber¬ land, IN 46229]. He says he will bring out a smart disc interface, an EPROM programmer, and other kits for the TS2068 soon.

I just bought some new soft¬ ware, too. The new "WS II. 3" word processor [Gesang Associates, POB 452, Randallstown, MD 21133 301/922-0767] does a good job. Tom Wood's "ZX Pro-File" [POB 64, Jefferson, NH 03583] ain't bad either. I liked the ZX/TS version of Pro-File so much that I bought the 2068 Pro-File and a subscrip¬ tion to "Pro-File Newsletter".

Maybe I'll keep both my sys¬ tems and look at the QL this fall.

You might tell everyone to simply put your name on all correspondence, as I have recently. I have sent out inquiries for TS2000 software and hardware. On each inquiry I wrote "I always read SYNTAX (Harvard, MA)." I hope we will be seeing someone pick up all the good Timex started: TS Modem, 80 column printer, microdrive, and TS2000 ROM cartridges for my dock connector !

James Tedone, Enfield, CT

Byte-Back (Rt 3 Box 147, Brodie Rd, Leesville, SC 29070 803/532-5812) sells their own modem; others (see previous letter and Vendor Report) sell modems that would have been the Timex modem. AERCO (POB 18093, Austin, TX 78760 512/331-0719) sells Centronics parallel inter¬ faces for the TS2068; most computer stores sell compatible printers.

Excellent R. J. Kingsley Sinware POB 8032

Sante Fe, NM 87504 505/988-2096 $24.95 + $2 P&H

Once again, Ray Kingsley has brought out one of the most power¬ ful machine-code monitors I have ever seen. Everyone planning to write machine code routines on the 2 068 owes it to himself to buy a copy of this package.

This latest version of HOT Z includes disassembly and data displays, ROM floating-point code display, four letter names for commonly used addresses (built-in and user-defined), hex code input, two breakpoints, single-step with register, flag, and stack display, LOAD ZX/TS tapes, and, most impor¬ tantly, a powerful on-the-fly assembler with delete and insert code commands. Of course, it also SAVEs and LOADS byte files, prints to the^TS2040, does hex arithmetic, block moves, and block compares. A slightly more complicated version of the block move will also recal¬ culate absolute jumps and calls (unless they reference the ROM). We're talking about a powerful package here. In fact, HOT Z has more functions than the 2068 has keys. This can be a problem: how do we access all the commands?

Sinware's solution consists of dividing the commands into three sets: read mode (the default), single-step mode, and edit mode. Since the command to run machine code lies in the edit mode, to try your program out you must first

position the cursor to the starting address, enter edit mode (via symbol-shift A), then set your routine running (via extended-shift R) . You get used to it after a while, but I would prefer having all commands that make sense in any mode available in every mode. Why can't I tell HOT Z to execute my code in read mode?

Besides the maze of keystrokes required for some actions, the only other reservations I have about HOT Z pertain to the manual. It runs about 40 pages, approximately half tutorial and half reference, but has no index or table of contents.

I am unable to make good use of the manual because I know what I want to do and why, I just don't know how. The manual insists on telling me what and why before how. Though it contains two tables describing the command set (one with single line descriptions and one with paragraph descriptions), some com¬ mands seem to have fallen through the cracks on one table or the other. Commands in the manual have names according to the keystroke used to access them, thus execute code is INT (extended-shift R) . Sinware picked that key because it Runs code; I think calling it Ex- Shift-R would have been clearer.

HOT Z itself never refers to the names for the commands; it just executes them. Why give machine code monitor commands BASIC names?

HOT Z does everything I need and want it to do. It does not deal with 64 column mode or memory bank switching by itself; you have to write code for these if you want to use them. It LOADS quickly and reliably and runs lightening fast. Ray Kingsley has made many important and intelligent decisions about how the system works. For this size computer, I can't think of a better way to write machine code: Nothing else I've seen gives

you the power of the processor without eliminating the beauty of the system.

BOOKWORM — TS2 06 8

This program will help you manage your book, comic book, or phonograph record collection.

Since my work involves daily inter¬ action with a large mainframe com¬ puter, I have taken the attractive screen displays and shrunk them to size so they fit into the TS2068 screen format.

Enter the program as listed.

In order to conserve memory and make the program execute faster, I have made extensive use of multiple statement lines. Note that all the statements on the same line after an IF get executed only if the conditional is true.

Once the program is in, enter CLEAR, and then LET f=9500. Now enter GOTO 6050. Start your tape recorder, then press ENTER. Book¬ worm will SAVE to tape. Once this completes, the variables will be assigned and the arrays will expand to full size. VERIFY each copy.

To use Bookworm, enter GOTO 1. Subsequent copies will be self¬ starting. If the program breaks for some reason, you can restart by entering GOTO 1. Never enter RUN, as this will destroy your data.

Bookworm stores approximately 425 titles as written in 48K RAM.

A ready to run verion of Bookworm is available on cassette with complete documentation for $10 from Magic World Software, POB 1184, Olympia WA 98507.

THE ARCHITECT — 8K/2K

BOOK REVIEW

This brief program produces an interesting, constantly changing display and demonstrates an inter¬ esting point about ZX/TS graphics.

It looks like an over-the- shoulder view of the architect's sketch pad while he plays with ideas for the shell of a high-rise building. Some of his plans are bizarre; some have a neat 3D effect. Some I liked well enough to record them on the printer.

Just as the right-hand wall com¬ pleted, I hit BREAK and COPY to retain his sketch. When I hit CONT, he went right on redesigning.

This program demonstrates that the PRINT and PLOT commands on your ZX/TS ignore negative values. The command PRINT AT -12,-12?"X" will not produce an "X" floating some¬ where to the left of your screen, but will have the same effect as PRINT AT 12,12...

Note line 80. This FOR starts the print of the plot pixel and the random graphics at the horizontal coordinate 54 and continues to -54. When the value of the loop control variable J becomes -1, it is read as a +1 and the direction of the printing changes to right to left.

John Wiley & Sons, Inc. 605 3rd Ave.

New York, NY 10158

212/850-6000

$14.95

This book's cover quotes Clive Sinclair: "Teaches skills of pro¬ gramming which, without its aid, might take years to aquire." Those who have struggled with the lack of advanced programming information in the TS2068 manual should take note.

Hartnell picks up where the manual leaves off and explains ways to make full use of the 2068's extensive capabilities. He deals with sound and color in depth, and casually points out programming techniques the TIMEX manual never mentions. For example:

10 INPUT "Start X coordinate";X prints the text in quotes at the screen bottom before INPUTing X.

Hartnell also explains how to get 121 different colors on your screen. Other chapters explain business and educational uses. Hartnell illustrates all these tutorials with excellent programs. Unfortunately, some listings con¬ tain errors and the print can be illegible in places.

Chapters on three dimensional graphics, machine code, and pro¬ gramming style finish up the book. Appendicies discuss Sinclair computer history, peripherals for the 2068, and Timex-Sinclair speci¬ fications. Many chapters have a list of further readings.

In spite of the somewhat slop¬ py printing of programs, this book clearly explains its many original ideas. It will be a valuable hand¬ book for anyone who wishes to use the 2068 to its maximum capability.

OUR POLICY ON CONTRIBUTED MATERIAL

SYNTAX invites you to express opinions related to any Sinclair or Timex com¬ puter or peripheral, or the newsletter. We will print, as space allows, letters discuss¬ ing items of general interest. Of course we reserve the right to edit letters to a suitable length and to refuse publication of any material.

welcome program listings for all levels of expertise, written in either Sinclair BASKT or Z80 machine code. Programs can be for any fun or useful purpose. We will test run each one before publishing it, but we will not debug programs; please send only workable listings. Programs submitted on cassette can be tested more quickly and with less chance of error.

In return for your listing, we will pay you a token fee of $2.00 per program we use. This payment gives us the nonexclusive right to use that program in any form world-wide. This means you can still use it, sell it, or give it away, and so can we.

We will consider submissions of news and hardware or software reviews. Please keep articles short (350-400 words). Again, we reserve the right to edit accepted articles to suitable length. We will pay 7 cents per 6 characters, including spaces and punctuation, for accepted articles.

When you send in articles for possible publication in SYNTAX, please include the following information:

• How to operate the program, including what to input if it does not contain

prompts.

• Whether you can run the program over again and how.

• How to exit the program.

• The Syntactic Sum (program published in June 81; send SASE for a free copy).

• What RAM size program requires.

• What ROM program uses (8K, 2068, Spectrum).

• For MC programs, what addresses must change to relocate the code and what ROM calls are used.

We pay for this explanatory text at the same rate as we pay for articles in addi¬ tion to payment for the program itself.

If you want us to return your original program listing or article, please include a sell -addressed, stamped envelope. Otherwise, we cannot return submitted material.
