Here is a method for installing a Toshiba TCS5S65 PL-15 Very Low Power CMOS SK X B RAM ($40 from Microprocessors Unlimited) in a TS1000 computer. Two of the great advantages of installation are the reduced power consumption (maybe as much as a 30% cut) and the absence of RAM pack wobble and crash. Who…

Review of the Hunter 8K ROM board.

You may be interested in a TSZX loading aid which really works; further, it allows one to easily align ones tape heads (the latter has been the source of all my load problems with the TS1000): no tape recorder has been properly aligned when purchased.

If you already own a ZX81 or a TS1000 you will be able to use this machine easily from the start. And, provided that the whole system of keyword entry did not turn you off completely with your earlier version of Timex-Sinclairese, this computer should be downright fun to run. One big advantage and also…

STEP is a program from Sinware. The ad says STEP is the ultimate debugging tool for programs in BASIC. I cannot say if this is true or not, But it sure comes close. STEP permits the execution of a program by several methods. The simplest is one line at a time. To use STEP, first…

This is the review of the AC CIRCUIT ANALYSIS program I promised you last month, but didn’t get a chance to do. The program is simply called AC CIRCUIT ANALYSIS PROGRAM and it functions like a miniature version of ECAP. Anyone who knows what ECAP is can skip to the next paragraph. For those who…

The TS 2068 computer will feature high resolution color graphics, a 4-channel programmable sound generator, full plastic keytop keyboards, typewriter format keyboard with full width space bar and dual caps shift keys.

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.

Review of the versatile calculation program.

The Glass Plate Game is a conversational one. Idea cards and markers are used, and the challenge is to build patterns of thought by finding interesting connections between the cards.

If I were selecting an interesting, affordable textbook suitable far beginners or intermediates, ages 10 to adult, this would be the book. It has a large number of program listing, very well explained, and the programs are interesting as well as useful. Most important is the careful explanations it’s also very well illustrated (even colored…

Review of the program by Mark Stueber.

News and rumors in the Timex community.

Sinclair has done it again. I expect you haven’t heard about his new computer – the QL – as it was only announced last week in Britain. The specification of the machine is very good and I will list some of the main points.

GREAT NEWS! TIMEX SINCLAIR 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…

Instructions and program.

In our joint meeting with the TI group in January we heard a presentation by Phil Kegelmeyer, son of Bill K, and watched in fascination as a simple program demonstrated ways that a computer can detect edges, vertical edges and corners. We’ll present a report on this program in our March issue. And we’ll also…

This is really a collection of short programs, reached by appropriate ‘GOTO’ commands. The first part of the program gives the appropriate line numbers names which are easier to remember, and dimensions the arrays.

Program to create and save character sets for the pseudo ROM board developed by Demby.

Adjustments to QSAVE for memory, speed et cetera.

Inside [a Timex Cartridge] one finds three blobs of what looks like high quality tar on a circuit board. Apparently they must weld down the silicon wafers themselves, which gives them a pretty good proprietary grip.

We have been to Boston to the Boston Computer Society Timex-Sinclair Celebration and were thoroughly introduced to the upcoming wonders of this machine. It is a very fine color computer with wonderfully fine color – much better than most of the competition: it will be able to send signal to a color monitor, color TV…

Our family had initiated a “job-jar” of weekly chores to spread out the housekeeping duties. My wife, who works, had strongly suggested that we all pitch in for the good of the family. Our two sons (aged 7 and 10) agreed and we selected a list of 20 jobs to be completed weekly. These jobs…
