It has been a number of years since I powered them up. Right now I think
they are both sitting disassembled in a couple of large boxes. I'm in the
process of construction of a building just for my old hardware, so once
that is done, I'll pull both of them out and bench them and see what their
problems were. I think the model 3 would start up, but just plain lock up
about the time it was going to boot. I think it may be a ram problem. The
model 4 didn't power up at all if I remember correctly.
