Articles like this one makes me wonder if dad's ZX81 clone is still sitting in the basement.
- rwmj 10y agoYour dad cloned a ZX81 or he has another company's clone of a ZX81? Tangentially related: The Jupiter Ace was a relative of the ZX81 (same designers, different company) which ran FORTH instead of BASIC. If anyone has one they are worth a lot of money because it seems fairly few were made and/or survived.

- digi_owl 10y agoafter having perused the big wiki and old-computers.com, i have come to the conclusion that it was most likely the Lambda PC 8300... http://www.old-computers.com/museum/computer.asp?c=1168 http://www.old-computers.com/museum/computer.asp?c=1168
- teh_klev 10y agoIf digi_owl's dad is/was resident in the US or Canada it could have been a Timex branded version of the ZX-81. There were also quite a few clones back in the day: https://en.wikipedia.org/wiki/List_of_ZX80_and_ZX81_clones https://en.wikipedia.org/wiki/List_of_ZX80_and_ZX81_clones

- osullivj 10y agoThe Jupiter Ace inspired me to port the Forth Interest Group's 8080 Forth implementation to the Camputers Lynx back in summer 83. There was no assembler for the Lynx, but there was a hex editor, so I hand assembled the 8080 ASM listing to Z80, and stitched in some calls to the Lynx BIOS for IO and graphics. Since Z80 was a superset of 8080 much of the code worked without mods. Happy daze!
- bewo001 10y agoThis web-based emulator (http://www.zx81stuff.org.uk/zx81/jtyone.html http://www.zx81stuff.org.uk/zx81/jtyone.html) is pretty decent. It even simulates the display wobbles if you put it into 'fast' mode.
