An Unopened Timex Sinclair 1000
By James Grahame
Here's your chance to grab a factory fresh Timex Sinclair 1000 (Sinclair ZX81) bundle including the computer, power adapter, video cable, 16K RAM pack and three program cassettes -- a $209.75 value, the box claims.
This could be a great addition to an 8-bit computing collection, although I find it incredibly sad that this little machine didn't find its way into the hands of an eager young computer neophyte almost 30 years ago.
The TImex 1000 was built around only four integrated circuits (some had an extra RAM chip), an RF modulator, and some discrete components. The membrane keyboard used the same technology as a microwave oven keypad - cheap and incredibly compact. Still, the machine included a decent BASIC interpreter in an 8K ROM and could be connected to a funky little thermal printer.
The video output was B&W, with a resolution of a 22 X 32 characters, but it was enough to get the job done. Well, as long as you didn't jiggle the connection to the RAM pack and lose hours of hard work in an instant.
