Ok, display sorted out, now to the next big hurdle. The #AppleLisaClone is throwing a error 45 which is a “bus error” and it happens as soon as RAM is being tested. So, npub19a8tdmlwgk7jhrwzttrqdtcfe8t27lzh90umlwmrl3xtdfvtsnwsw7lsy2 (npub19a8…lsy2) and I suspect the issue lies on the new RAM board.

I’ve tested the SIMMs in a Mac Iix and they work. I’ve also pulled all of the TTL chips and they tested good on the Chip Tester Pro.

Kinda stuck at this point. Having another RAM card would be very useful now.

Ideas?
