A cheap but versatile microcomputer-controlled temperature controller costing less than $100 is described. The system is built around a Timex/Sinclair 1000/ZX81 microcomputer. This is a truly digital system employing the proportional-integral-derivative feedback-control algorithm, thus making the system capable of producing any required temperature profile at a low cost.

Why upgrade the TS1000 video with a TMS9918 video display processor (VDP?) If you find that your computer does its job, but you would like to see it work a lot faster (in SLOW), if you’re tired of that annoying fast mode flicker, if you have a program longer than 16K of BASIC and want
Here is a project that will let you “burn” (program) EPROMS using your computer. It will handle either the 2764 type (8K bytes) or the 27128 (16K) EPROMs.

One of the nice features of the Z80 is that it has a number of commands which actually are a whole subroutine in a single op-code or machine-language instruction. Quite probably the most powerful of these are the “block-transfer” group of commands. These allow you to easily transfer blocks of memory anywhere you wish, at

If you have a Memotext word-processor module and 64K RAM, you undoubtedly have already made use of its powerful “text” files mode. Memotext also supports “data” files, organized in six fields per file, up to 31 characters per field. Entering data files is just as easy and fast as text, thanks to the re-defined keyboard,

Todays word is SPEED. Regardless of which machine you own, you can speed up your SAVE and LOAD times in several different ways. The most economical is the tape based fastload, of which there are several programs out for the 1000. The 2068 has a speed limitation due to design considerations, although it does load

The program presented here creates a modified LOAD command. It moves the routines needed for the LOAD from ROM into RAM and adjusts them to work there. The routines are changed so that when the LOAD completes, machine language code from the 1 REM statement is executed. By changing statement 1, you can completely control
