The NCR SCSI chip - UI12 (53C80) - has been known to fail, twice in SE/30's I have owned.
It would be worth checking its solder joints with a microscope but changing it out - if you can find a replacement - requires hot air soldering equipment that I don't have access to any longer.
Capacitor leakage is usually visible as transparent contamination a centimeter or two around the capacitors. If it isn't visible with a little magnification it's probably not your problem.
Visual inspection of the board shows it to be clean. I don't see any obvious signs of capacitor leakage, so I suspect it's the scsi chip itself given the symptoms. Drat. I'm definatly not setup to pull/replace it. So, guess it's time for this box to move on, it's either getting a g3/g4 rammed down it's throat, or, well, I don't have an 'or' figured out yet.
