Wondering if someone could help me take a stab at this. Guy i bought it from said it was working but now when i plug it in i get a garbled screen like this. I don't see any screenshots like this on the usual sites that talk about graphics glitches. This must have been one of those ms pac boards that works without the daughter card because the guy said it worked fine before and it has the z80 chip in the spot the daughter card ribbon should go. I've reseated the boards, cleaned edge connectors and reseated roms so far with no change. Thank you in advance for any help you can provide.
