Yeah, I was talking about the SGi groups in particular. Most of them haven't had
posts in months, except for spam.

I didn't really think of that when putting it in the shop. I have lots of shelving,
but the few bigger computers were put on the floor. Thinking about it now, I
need to get my Mac G5 off the floor, too.

I guess I'll find out. ;-)

That's what I've done. The PCBs look clean, and the caps all look OK. I was
just hoping somebody had some pinouts for the power supply connectors so
I could see what I need to trigger. I have traced one side of the power switch
to the power supply, but can't find what the other side connects to. So I don't
know if I need to hit the PS with a ground on that pin, or a voltage of some
sort. (I would expect the supplied voltage to be derived from the switching
regulator that I hear running, somehow.)
