Mac Classic almost booting, diagonal lines but no question mark
Posted by: daguil on 2024-10-20 08:58:47
Back with the same mac classic I had posted about before. Long story short, I was able to fix the analog board and am now getting a solid 5V as well as 12V. The mac bongs, but gets no further than some tightly packed diagonal lines. No blinking question mark. The interrupt switch leads to a sad mac, as expected. From prior desperation (before I got this far) I have already replaced the CPU, RAM, and VLSI chips, so those are all known to be good. Additionally read up on someone having a similar issue so I tried replacing the ADB chip, and reflowing a bunch of possible issue joints on the analog board, yet still no change. What could be the issue?

Nevermind! I am happy to say that after replacing the VIA, the Mac boots!
