I have an SE/30 whose logic board is in decent shape - considering its age. The Original battery was still intact (and now in the trash) so just some electrolyte corrosion.
My question, is it really harmful to run it without replacing capacitors? Capacitor C5 had come off completely.
Why would I want to run it this way? I was to do some troubleshooting to see what chip(s) are causing lack of vertical sync. So I can order the caps and other parts at the same time to save on shipping. I suspect one of the SOIC chips in the video circuitry, their legs are corroded. I wanted to run the machine long enough to probe around with my oscilloscope to hunt down the bad IC. I get a happy mac chime via the headphone jack, so the CPU is executing code and I believe this means the RAM is OK?
I am bench testing the logic board with a CayMac Vintage SE/30 Compact Analog & PSU Replacement Board and a PicoPSU. So I am not using the original power supply or analog board.
