I've got zero ideas of what to look at and really don't want to just start randomly changing parts. Another set of eyes would be helpful. Thanks. I know some of the trace repairs look a little dodgy but they tone out good with no shorts I can find.

Need advice. Started with a working SE/30. Recapped the analog board and power supply. Both work find an SE logic board. Recapped the SE/30 board and ended up with a Simasimac screen. Reseated RAM and ROM. Still got Simasimac. Replaced two small chips that looked corroded (UE8 and UD8). Toned...

I think I figured it out. The pin numbers on the schematic being out of order really threw me. I've toned out about half the board now and so far everything is testing good. I see the matrix in the schematic I have but I can't make any sense of that.

Is there an easy to follow guide on toning out the traces of UE8 on the SE30 board? I have the schematic but I don't really know what I am looking at. Like why are the pin numbers out of order? Are those even pin numbers? I found a nice diagram of the sound chips with lines drawn over the...

Just finished a recap of what was a working SE/30. No bomb but some leaky caps. Now I get Simasimac on the screen and no bong. I do get some static via the audio jack on boot. I have NEC VRAM chips if it matters. I have reseated the ROM and the RAM. I have checked continuity on all the pins for...
