Here are some pics on the PS in my Genesis MP.

The board, I believe, is just the Apple board with a Daystar sticker on it, so I don't know why the Apple PS wouldn't work in theory; however the Genesis has a lot of leads to supply the drive cages, the power connector to the CPU board, etc. so I don't know if the Apple PS would cover all those bases.

I tried to power up the machine, but while I got chime, I didn't get any video out or signs of otherwise booting. I've had this happen before. Usually re-seating the processor card would allow the machine to boot, but that didn't happen this time. I put in the G3 upgrade card that the machine came with originally, and same result. PRAM battery is good, in case that matters.

I didn't take a close look at them, but there are a lot of caps that probably need replacing on that board. Uniserver will probably be getting an email soon :

Hope these pics help. If you need the Daystar files for the machine, there are ways...
