I don't have a dishwasher :), but I carefully scrubbed it w/soap & water

I put a good PRAM battery in, and cleaned off the edge connectors.
Unfortunately I get nothing when I power the system on. (It's a
two-step process -- there's a main switch on the back, but the power key
on the keyboard is what tells the system to power on.) Without the
motherboard installed, the fan kicks in and the hard drive powers up, so
I know the power supply is working (voltages seem to be fine.)
The only diagnostic ref I can find is a really really basic
board-swapping checklist. Any suggestions on what to check that is
preventing the machine from powering on?

It's not battery corrosion -- the board is
literally rusted, all over
:). The battery's nasty too, but that's only a small part of what's
wrong with it. I suppose I can soak it in something, maybe scrub it
with a toothbrush and see if that helps at all, but it's pretty bad.
If the board is indeed toast, you've got nothing to lose by sticking
it in the dishwasher to see how much of the crud comes off...
