Wanted: Zilog Z80, week 17 1982
Wanted: Zilog Z80, week 17 1982
For originality (in an Issue 1 Spectrum as it happens) I'm looking for a 1982 Zilog branded Z80 that is as close as possible to week 17. Perhaps someone has a socketed one of that date in a ZX81.
Happy to swap for a newer Z80 or to pay a fair price.

I have an 8204. CPUs were often earlier than the ULA so if nothing better comes along it may be an option?
I have only just got it so would have to test it properly first.
My issue one has an 8208 Z80 and 8214 ULA.

It has happily run The Gauntlet and Rock Crush with a Chroma81, Memotech Keyboard and ‘Spand plugged in for about 10 mins so seems fine. Happy to soak test for an hour at some point if you want?
Hard to believe but the screen is actually white!

Thanks. Looks good them. Leave it on for an hour, but only if you have the time.
