Yeah, the oldest PowerMac G5 and RackMac were not super big sellers
either, relatively to the newer models.  And of course all Apple
hardware of the time (as well as all by other manufacturers) had failing
power supplies, so there "naturally" be fewer working machines over\
time.  Problems that solve themselves!

Booting, yes, but it won't run for even a minute ;-)

Is this all supported models?  Might be better to do that immediately,
not wait for patches to trickle in over the years :-)

Thanks everyone!
