I don't know if the mentioned clones are software compatible. The Lambda 8300 clones weren't.

a few more, two from the east block, one from china:

didactic from Czechoslovakia.

P.S. This is actually a spectrum clone, look closely at the top row of keys and you can just make out it lists colours.

I have schematics of many of these clones, from my study of the ZX81 when designing my own ZX81+35 clone

by the way, the very first clone of a ZX-class Sinclair computer was the MicroAce which came out in the USA just months after the ZX80 was launched in the UK, and was clearly a direct copy of the ZX80, even including the original ROM, it later became licensed, but originally it was simply a pirated copy, with the idea that software did not have legal copy protection.

Oh, most interesting!

PS: Hmmm, actually Didaktik series contains clones of ZX Spectrum, also what the "M" model is.

You are right, the didaktik M is a spectrum clone, not a ZX80 or ZX8 clone, in the didaktik series there is no ZX81 clone.

the best, most complete, "list" I could find about ZX81 clones is in the Czechoslovakian wikipedia page here: https://cs.wikipedia.org/wiki/Klony_po% ... X80_a_ZX81

use google translate, or google chrome to translate the page.
