Macintosh SE/30 - June 22, 2025

When I acquired this machine, I started by removing all capacitors from the logic board and cleaning up the corrosion. Thankfully the battery had not yet leaked in this unit. After that, I installed new capacitors and the machine runs and boots, but had video issues. After purchasing new ICs for the video circuit and replacing UE8, the system would start up with proper video. I did notice the sound was unreliable though, and that ended up being because the molex power connector had the -12V line corroded through on the logic board! After replacing that connector (with one from an ATX style scrap PC board), audio was significantly better. Now that this machine is fully serviced and running, I will be installing A/UX on the internal BlueSCSI hard drive emulator, to experience Apple's odd version of UNIX from the 90s. Updated 11/06/2025
