Keith,
I can tell you what my experience has been with the G3 motherboard problem (since corroborated by a message I saw recently on Macintouch...I think it was Macintouch).
For some reason or another, the G3 266 desktop I've been working on suddenly stopped booting. The problem began innocently enough, with incomplete start-ups and problems with the sleep mode, but eventually (within a matter of a couple days) I got nothing on powering up. I couldn't boot from the CD ROM, I couldn't rebuild the desktop file, nothing. All that would happen is that the light on the front of the internal Zip would go on for a bit, the CPU fan would start up, and then nada. No hard drive access, no monitor.... Believe me, this is a scary thing to watch happen to a brand new machine.
Of course the machine is still under warranty, so I took it back to be repaired, which did entail replacing the motherboard. Since then everything has worked just fine. I never did get any reply as to the specific nature of the problem, but I've read speculation that the voltage setting on the back of the machine may come set to 220 instead of 120. I'm no Apple technician, so I couldn't tell you exactly how this difference in setting might eat up the motherboard. Hopefully there'll be more information available on this issue soon. Could just be a bad bunch of motherboards...?
Good luck to you today, Keith.
