Add a LOAD/SAVE CODE capability to your ZX/TS with this MC

Bill Russell tells SYNTAX he's creating some new products for ZX/TS machines as well as for the 2068. We can't say much at this point, but at least one will be the kind of software-hardware product that typifies G Russell efforts — like the speech recognizer.

SINCLAIR STOPS PRODUCTION OF ZX ACCESSORIES

Vendor Reports . 3

Coming Next Issue Read Headers on 2068 (and Spectrum) tapes to get the program specs.

No more RAMpaks and ZX printers will pour off assembly lines. Even the fabled ZX81, once made at the rate of one every 10 seconds, will now be produced only to order, and then mostly for export.

K-POWER TO FULFILL TSU SUBS

SPECTRUM MC ON 2068

Subscribers to ECC's ill-fated new venture into North America, Timex- Sinclair User, should have received postcards by now, offering K-Power to complete their subscriptions. Scholastic Magazines publishes this 64-page slick magazine, which runs Timex-specific programs, as well as covering the Adam, Apple, IBM, TI , Atari, TRS-80, VIC-20, and Commodore 64 machines. Ad rates of $6300/page limit ads from Timex- only suppliers to the very largest.

TS USER NL (YAGSEE) FOLDS

Yagsee Publishing stopped producing TS User newsletter with the Apr. 84 issue. According to Derek Stubbs, Timex's exit, followed by others, left a market without new customers as old ones moved to other machines Renewals & subscriptions dropped, & YAGSEE' s informal survey projected poor financial performance. But you can still buy all of vol. 2 + the 2 issues of volume 3 for just $11.95 POB 155, Vicksburg, MI 49097

SMART TERM II DELAYED

Upgraded performance for Westridge' 2050 modem will have to wait a tad longer, but we do not know quite when. The death of Stuart Lotwin seems to have thrown the company into chaos — phone calls unreturned, information unavailable, and people answering the phone who seem not to care. All of us will miss Stuart, and his rescue of the 2050 assures his place in our memories. May his family find solace in their grief.

NO NEWS ABOUT NO DEAL

No persons knowledgeable about the bulk sale of Timex inventory or any proposals from any potential buyers were available at Timex. Doug Smith verifies that all computer hardware inventory is sold, and a bulk buyer bought much of it.

The Ocean State Users Group reports that they successfully entered and used Spectrum machine code programs from the UK magazine Your Computer. Blockman, I.T., Lifter, and Doom Church all went fine. Only the program to copy Spectrum programs failed. Contact Bob Dyl at 401- 849-3805 (eve) for details.

LI GROUP LOADS AND MODIFIES TT

Paul Donnelly sent us the Jun.84 issue of L.I .S .T.inq . the monthly newsletter of the Long Island Sinclair Timex Group, containing full instructions for converting the Spectrum program Transylvanian Towers to operate on the 2068. TT is SAVEd as CODE, allowing you to LOAD the bytes to higher locations in your 2068 and then modify them as necessary. Reach them at 10 Idle Day Dr., Centerport, NY 11721

SYNTAX LABS LOAD SPECTRUM SOFTWARE

SYNTAX tried following the LI user group's instructions with 3 German programs from Profisoft. We could LOAD Pinoo. Jangler . and Alien Curse . and locate the system variables but we did not succeed in making all the necessary changes and moving an altered program — yet.

ZILOG POLICY CHANGE

Since the ZX-80 days, SYNTAX sold Zilog manuals as a reader service. No more though, because you can now get them free by writing direct: Zilog, Inc., 1315 Del Av., Mailstop Gl-5 , Campbell, CA 95008

45-PLAYER COMPUTER GAME UP IN MIAMI

American Software Technology is testing an interactive, multi-user, real-time game where you interact with other players as well as the computer. You can call Enternet at 305/866-8060 at 300 or 1200 baud. You may pay by VISA, MC, or pre¬ paid deposit account. Currently, the game is Fazuul, an adventure game. Your object is to escape the planet — you may team up with or against other players. You pay for the call plus 3-6 cents per minute (depending on your modem speed) .

ZX SPECTRUM SOLD IN CHINA

Sinclair Research, Ltd. will sell 600 48K Spectrum computers to the computing and automation department of China's North East Technical College. According to Charles Cotton, head of Sinclair's export department: "China is a very

important potential market for us, and one in which we are investing considerable time and effort. This deal represents an important stepping stone to further opportunities . "

Wogen Engineering arranged the contract and also demonstrates the line of Sinclair computers at Wogen offices in Beijing and Shanghai. A consultant to the China trade, the company also maintains a London office and deals in metals, barter, and counter-purchase deals, with an emphasis on high-technology.

Sinclair will supply a library of introductory programs including microPROLOG and LOGO. Graduate researchers at the college will use the Spectrum as an effective, low- cost means of learning BASIC skills

TIMEX TECH MANUALS SHIPPED

Timex shipped its initial stock of photocopied 2068 Tech Manuals and has orders for its scheduled print run. A few orders were returned by mistake. Re-order — the print run

will be expanded. Delivery to Timex is scheduled for 15 August, so you will not get your copy until 3-4 weeks after that.

MAGGIE BRUZELIUS LEAVES SINCLAIR

Facing an offer too good to refuse, Maggie became Director of Marketing for Alpha Software (Burlington, MA) One of the few growing software houses. Alpha sells an integrated package with database, spreadsheet, word processor & communications for IBM PCs, JRs & XTs "We're steaming full ahead on business productivity software. Electric Desk is easy to use, comes on one disk, needs no extra memory & sells for only $345. It really is neat!" says Maggie.

VENPQR REPORT

Byte-Back has nearly cleared up its backlog of 2068 modem orders, but is shipping only the dumb terminal software. Jerry Minchey hopes to get the smart software out quickly, and will send the tapes in a follow-on shipment. The current version is a dumb terminal with printing capability.

Ray Kingsley of Sinware believes that some of you may have purchased bootleg copies of an early version of HOT-Z with a bug in it. Ray says he is the only legitimate seller of HOT-Z. If you purchased stolen goods, seek a refund from the seller and reinvest with the program owner. A simple offer to provide postal inspectors with evidence of the transaction will work wonders if you meet resistance

We received an allegation from Canada so startling that we dare not print it. Suffice it to say that Timex software does not come in baggies with photocopied documentation and brand-x tapes. SYNTAX suggests that you do no business with stores that offer you such merchandise.

DATASAVE — FILES WITHOUT PROGRAMS

8K/16K

DATASAVE allows you to save a selected portion of memory to tape and then load it back again to any part of memory. Loading code with DATASAVE does not (of necessity) write over the program that you are running, so a program can load data from tape, manipulate it, and then save it back to tape.

DATASAVE's machine code (MC) resides in the first REM. To make the REM, type listing 1 exactly as shown. Note that there are a total of 155 A's, and the last line of REM should have four A's.

If the Syntactic Sum checks out, RUN the program and enter the numbers from listing 2, reading left to right. When the program stops you should see a screen as in listing 3. Skip the next paragraph if the Syntactic Sum agrees with the one shown following listing 3.

LISTING 1

LISTING 2 — POKE TABLE

If you have a wrong Syntactic Sum, add lines 1000-1040, shown in listing 4. RUN 1000 and check the data on the TV screen (ignoring the final five numbers) against listing 2. POKE as appropriate to correct data, or if you need major repairs.

re-RUN the whole program. Now test for the Syntactic Sum shown at the end of listing 4.

Delete all line numbers except 1. The Syntactic Sum for line 1 is 18612. As a precaution, you may want to change the line number to 0 with POKE 16510,0. This prevents accidentally editing the REM. The POKE makes the Syntactic Sum 18611.

DATASAVE works much like the ZX/TS's normal SAVE and LOAD: it uses ROM calls when possible. Set your recorder as you would normally for SAVE or LOAD. No "program name" is used, so none is required to SAVE data, and the first data found during LOADing will be read.

Look at listing 5 to see how you can use DATASAVE. Variable S defines the start of your memory area to SAVE or LOAD: E sets the end. After defining S and E, you SAVE data with RAND USR 16514 or LOAD data using RAND USR 16543. Change S and E as you wish. The sample in listing 5 SAVES and LOADS the top 1024 bytes of a 16K memory. Set RAMTOP below this area.

LISTING 5 (append these to 1 REM)

Three error reports can occur when using DATASAVE:

Report 2 - S or E not defined

Report B - S or E out of range (0-65535)

Report D - BREAK depressed When you use DATASAVE its Syntactic Sum changes. Restore it to its original value with POKE 16667,0 and POKE 16668,0.

DEAR EDITOR

I 'm quite put out.

You say you're going to charge $48 for SYNTAX because of increased costs. You point out that Time Inc charges $48 for their 12-pager, and this justifies your decision.

Time's newsletters are about IBM and Apple, which cost far more than ZX/TS computers. Time will charge "what the traffic will bear"

My total costs to subscribe to ZX Computing (156pp) are $24.33 for six issues & Sinclair User (148pp) costs only $43.56 for 12 issues.

Why should we pay you $48 for 12 twelve-page newsletters?

John Sampson, College Pt. NY

John, I personally talked to Time's newsletter publisher about your point. Not so. The traffic would have borne far more — $48 is the lowest price Time considered.

You pay $48 for value. Here's what 7 survey respondents said about the value they've received.

"As a newcomer to computers 2 years ago, I needed all the help I could get and found that SYNTAX (recommended to me by a freind) pointed the way to a lot of places I would not have found otherwise."

"I appreciate your avoiding the high gloss and continuing with high quality instead."

"It is virtually impossible to assign a dollar value to your publication, but some of the explanations and examples in your articles helped me to get my present job, which is obviously worth a great deal to me."

"I learned a tremendous amount from SYNTAX & to date I've learned more about computers from SYNTAX per $ spent than any other computer publication I have bought."

"Each good item is worth the price of that month's issue."

"Please do eveything possible to continue publication. I would happily pay 2-3 times the price if

needed to cover lost income from faint-hearted supplier's and manufacturer's advertising."

SYNTAX is going the way of the dodo it will not emulate the phoenix. Anyone who has nerve to charge $48 a year for the junk that has been printed in the past nine months deserves to fold. If you had a decent newsletter that would attract advertisers there would be no need for a 70% increase.

Clifford Efaw, Morton, WA

Courage is the most important virtue. Without it, no other can be consistently practiced.

Ex-advertisers owe SYNTAX and SQ $22,690.10 — and we switched to pre-pay in Jan. 83! All companies on the Apr. 84 list were asked to advertise, you see the results.

Those who get $48 in value from SYNTAX should have the chance to keep on getting it — KO.

Inf oWor Id's news page carried a report about TimeStar and the Timex Sinclair Computer. Synchro-Sette carried a similar artcle in March. Your publication was quick to denounce such reports as unfounded rumor, and even to assert that Timex was not negotiating or had received no proposals. It seems interesting that the last major publication for Timex Sinclair Computers can not find out information that a magazine like InfoWorld is able to obtain.

It seems to many of us that you would better serve your own interests, as well as your readers, if you would investigate this possibilty fully and encourage Mr. Higgenbach (sic) instead of throwing cold water on such a possible deal.

Lonnie Kendall, Reidsville, NC

I believe in the stance taken by news stories in SYNTAX — KO.

Programmers who want to alter the Westridge Modem software for ZX/TS machines must first POKE some locations in the REM line to avoid crashes. Here's how:

LOAD the TS1000 software.

At the 0/0 report, type:

POKE 16529,149 POKE 16530,14 POKE 20264,118

Now you can add BASIC lines.

The authors of the modem soft¬ ware altered the pointers defining the length of the REM holding the code. Thus, when a user tries to add additional lines, the program crashes. The POKES correct these pointers and place a 118 (ENTER) at the end of the line. When the computer sees this line properly, new lines can be added.

Also, Westridge uses port 115d for data and port 119d for control of the 8251 serial chip inside.

Thomas B. Woods, Jefferson NH

Is there a way to reset ZX/TS computers and retain the contents from 16k-RAMT0P after a crash?

Also, where will I find ways to use extra keys to get shifted functions or FUNCTION operations with single keystrokes?

Bill Jones, Panama City FL

SYNTAX knows of no simple way to alter the reset scheme to save the main memory area. Also, it might do no good to do so — how will you know the state of the machine?

You add shifted key functions with diodes (SQ Winter 82 p.29) or ICs (Mar. 81 p.7) or double-pole switches (Jan. 83 p.10). To do the functions, you need 2 keystrokes — one to shift mode, the second to select the specific operation. You build the mode selector as shifted enter or 9, then use either the primary key or a specially marked one to make the second stroke. McGraw-Hill's new book. Beepers, shows an opto-isolator scheme for functional keys & a CAPS lock — KO.

I am surprised that you stated that there was a bug in my COMPILER when I also sent you a correction to that bug. The correction probably did not arrive in time for publication, but please print that the bug has indeed been corrected.

The review placed very little emphasis on the ability of COMPILER to handle strings and very little was mentioned of the Z80 ASSEMBLER that comes with COMPILER.

I think most readers will be pleasantly surprised if they buy the compiler. It is not as user- unfriendly as you make it seem For one thing, you can run most pro¬ grams in BASIC prior to compiling This helps to de-bug programs.

I don't know what you mean by "display poor"....

John Richard Coffey, JRC Software

Scottsburg, IN

Your correction arrived on 5 July, the issue was already on press. We review the product we have, not the one the supplier promises. SYNTAX reviews only production versions of products. As you say, there was a bug. Years ago KO heard Dr. Harlan Mills of IBM say there is no formal proof that the last bug has been found — you can never know your code is bug-free unless you use methods that generate bug-free code. Most experienced programmers know "where there's one, there are many."

SYNTAX reviewed only COMPILER, as the first and last paragraphs of the review emphasize. We therefore have no comment on the assembler other than to note that you sent us 2 corrections to that program, too.

Most does not mean all. If my program doesn't run, how do I know if it's my mistake or yours? Our program ran in BASIC, but not after compiling. If we use one of your non-standard BASIC constructs and it fails to run, what then?

"Display: Poor" means error

messages just print on the screen without formatting or organization.

LINESUN — 8K/1 6K

Locating errors made in typing from printed listings is easy when they include a checksum for every statement, and you have Linesum loaded. It displays, line by line, any BASIC present with line numbers below 9000, & displays the sum of the line's bytes. Add the line sums to get Syntactic Sum.

Linesum's flexibility surfaces with use. You LOAD Linesum first, then after typing in a program line you RUN 9000 & use the edit option to fix errors or type another line before returning to Linesum. That way you check every program line as you type it. Use the quit option to free the computer to calculate, and reenter Linesum at the point you left it by typing GOTO SUM.

Long programs may be finished piecemeal: if you tire, "quit" &

SAVE your partial program. LOAD it later & take up where you left off. If you get an inspiration and want to try a BASIC routine while it's fresh in your mind, do it. Lines 9536-999 are your work area. Don't even clean up: test programs in this area vanish when you erase Linesum. With a merge utility, you can type your new program, and only append Linesum if the Syntactic Sum indicates you have made a mistake.

Once you start Linesum do not use RUN until you are all finished with Linesum. Do GOTO SUM instead to avoid killing variables.

To make your copy, LOAD your Syntactic Sum tape, then type in Linesum. Don't type the checksums or the GRAPHICS 5, they aren't part of the program. Syntactic Sum at this point equals 35581. If you get a different number, find and correct any typing errors. Put your ZX/TS in FAST, then SAVE this version to a scratch tape.

Next, RUN Linesum on itself, verifying each line in turn. The Print option stops at each line — the Lprint option runs by itself.

Add 1 REM with 22 placeholders

Next, RUN 9505, to load the MC (machine code) into the Line 1 REM. Enter all numbers on the POKE list, then a STOP to exit the loader.

EDIT Line 1 to line number 9490.

Now edit line 9325, changing 9999 to 9000. Linesum will no longer work on itself, but only on program lines below 9000. The new Syntactic Sum will be 38824. RUN linesum to get the result shown:

Delete line 1. SAVE the program to tape for future use. At this step, Syntactic Sum is 36230.

Leave Linesum loaded and type in the program "DATASAVE" shown on page 5 of this issue. You won't be able to get a correct Syntactic Sum using the standard Syntactic Sum program now, as Linesum is also present, so do RUN 9000.

Now you can step through the typed-in program 1 line at a time. When the displayed checksum differs from the printed one, use the edit option to switch to normal BASIC listing at the current line. Find & EDIT the error, then do GOTO SUM to go back to Linesum for a display of the edited line and new checksum After everything is fixed and your line checksums agree with the printed ones, you reRUN, using the LPRINT option to get a LISTing with linesums and the Syntactic Sum.

turn to p. 10

When you finish, erase the entire Linesum program above 9000 using: GOTO 9485 & 9000 ENTER.

Linesum is menu-driven with 3 options after each line display: Next Line, Quit, or Edit Current Line. At the beginning, you choose screen or printer output. At the end of a screen session you can examine the Syntactic Sum.

Lines 9485-500 erase Linesum. Line 9485 gets the address of the next line. The relocatable machine code routine in line 9490 computes the Linesum program length (from 9000 to the end of BASIC program area) and stores this number minus 4 in the text length bytes of line 9000. When you delete line 9000, all of Linesum disappears.

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.

We welcome program listings for all levels of expertise, written in either Sinclair BASIC 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.

I WANT IT ALL — RIGHT NOW

And we've got it for you — the chance to upgrade to a 2068 with a 2040 printer and a 2020 recorder plus great SoftSync software and, of course, a chance to catch up your SYNTAX collection — or start one if you've been a recalcitrant up to now.

As you know, dealer prices on this stuff are rising, when you can find it! But we've got great packages that let you save and get everything you really want.

These packages represent real savings over the list prices of the separate items and you get the convenience of dealing with one reliable company while saving. One quick command and your 2068 system will be on its way within days.

We haven't forgotten the ZX/TS owner either, with a printer plus Works II package — the most-wanted peripheral and the most-needed information at only $>170!

If you're buying a 2068 from us, you'll get a 13— issue subscription tailored to your needs — Dec. 83-Dec. 84 — that addresses your need for 2068 information. If you have a ZX/TS and need all the back issues too, choose the $499 package — worth $738 at list — and you'll receive:

o 37 back issues of SYNTAX thru Dec. 83 o 2 binders with library-style wires o 3 back issues of SQ — all there are o 12 issues of SYNTAX — Jan. -Dec. 84 o 2068 Personal Color Computer o 2040 printer o 2020 tape recorder

PLUS THESE WANTED SOFTWARE PACKAGES

o Zeus Assembler Full-Screen Editor o Personal Accountant 3 Programs o Gulpman 15 Nazes, 9 Levels of Play o Cyber zone Voice-Activated Lasers o Voice Chess Awesome
