Re: 9010 Z-80 Pod Help needed

Thank you John,

I opened my both 8080 pods and there is no tied together pins and
apparently no grounded pins...

Mixed the boards and now I got one of them working - at least self tested OK.

I bought them from ArtFromNY about 10 years ago, maybe he has some
clue on what cable is it.

Thanks,

JL
