Since I need to wait on RAM chips for the 128K, I figured I would work on one of my extra nasty SE/30 boards. LOTS of corrosion from the leaky caps. No problem popping them off with the hot air station, pads cleaned up fine. 30 minute of vinegar and a toothbrush got most of the fuzzy off...
Finally getting around to fixing the 128K. It chimes on startup, but then immediately goes to Sad Mac.
Looks like a 0200?0 code, so I'm guessing memory in either F9, F10, F11, or F12 according to https://udcf.gla.ac.uk/~gwm1h/Error_Codes/Sad_Mac_Codes.html
Any further hits given the video...
