Oh, no. I thought we finally had an SE/30 fully working, but it's not! I connected a speaker to the logic board, and it doesn't actually chime. When I try to play sound, the whole system freezes😭 Bad chip? Or bad trace?
Seriously. What is this thing? It looks like a regular CPU speed display but it has a battery and a chip with the silkscreen removed. It was connected to the reset switch only. 🤔🤔🤔
