semi-OT: Power Computing 100 power supply

Jim's post had a good link -- powerwatch.com. (Thanks!) I am on a
cruddy connection right now, so haven't pored through it in depth yet,
but take a look.

What I may do is look for an entire Power 100 machine on eBay (found
one last week, but the seller pulled it unexpectedly before it was due
to end). They're usually pretty cheap. If I end up going that route to
get a PSU, I'd be happy sell you the rest of the parts for cost of
shipping. (Probably ought to keep them for the next piece that fails in
mine, but I don't have the space for that. Plus I will become obsessed
with finding another PSU to make the second PC100 work, so I'll buy a
third, etc.) Obviously if we did this, you would still need a power
supply too, but might be a good way to share the cost of other parts.

FYI for when you either patch up the one you've got, or replace it. In
the powerwatch bulletin boards, for Power 100s that don't boot, people
said to check three things: The logic board battery (I remember that
from other Macs -- and mine is testing a little low, so I'm gonna go to
rat shack and try that first), the fuse in the PSU (mine's fine), and
the lithium button battery in the PSU itself (! what? Anyway, mine
tested fine. Why does PSU have its own battery? lol). One thing I
wondered about -- I tried to test the power supply itself by plugging
it into the wall, flipping the switch to "on", and probing the leads
with a voltmeter. Nothing. But with this particular computer, you have
to have that switch on AND push the soft power-on button, either on the
front of the case or from the triangle key on the keyboard. So, is it
possible that the PSU is not dead, but that I am not getting anything
because the power-on signal's not being sent when it's not in the
computer? Not, not, not, not?

Sorry for the ignorance. I want there to be a giant scorch mark and
melted plastic if the power supply's really had it -- that'd be more
convincing. ;)

Thanks again,

-- MB
