Gotcha beat Andy, my first one, a Cosmac Elf, had 256 bytes. RCA 1802 MPU. A "different" architecture, but one that could be quite miserly with its memory usage. I learned how to program it using its monitor and a hex keypad, then added a 4k static ram board plugged into an s-100 buss backplane ($400+ dollars back then) and, laying ground for my machine control efforts now, made it into a machine controller for U-Matic vcr's. Likely still in use with some mods to the software timing loops, from the day I installed it in KRCR's control room in 1978, until analog tv was shut down in 2008. It even generated the video from some hardware I made. The video was a 2 very large digits digital version of the academy countdown in front of most programs in those days. > Someone managed to write a playable chess game. > https://en.wikipedia.org/wiki/1K_ZX_Chess Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
