Removed old System 1 power supply board for reconditioning with the capacitors, etc, that came in from DigiKey. We will be following recommendations from here: https://www.pinrepair.com/sys1/

We found one wire to this power supply board had been broken or cut near the Molex connector (see photo).

Right now, it is hard to be certain how to separate the board from its metal backing plate. Olivia and I believe we need to desolder the transistor on the back side of the backing plate.

This power supply board is nonstandard, and has clearly been worked on before.
