This looks very cool. Some Atari folks designed new boards for Its 8bit line. I wanted to build one, but could not justify the expense. Was going to be over $500 to build one myself. The wife would kill me. But this appears more affordable. And I just happen to have a Timex Sinclair 1000 that may have a bad PLA chip. Looking forward to your bill of materials list.

@mahjongg very very nice project, compliments!
regarding jumpers, would it be nice to have one switching from the 4k ZX80 ROM to the 8k ZX81 one (and also slow mode)?
(with the 16kbyte ROM both fit at the same time and is a matter of switching just address bit 13)
