The sims are in their original factory positions and have worked fine
there for over 5 years.

Yes, it boots sometimes, but it's getting harder to boot now. I only got
a serial cable for ttya a couple of days ago, so until now it was a
'real' mystery why it wouldn't boot. I've event tried booting from the
cdrom and it gives me exactly the same problem.

I've got a PC board (i.e., personal computer) for running windows in one
slot, and it's daughter card in another slot, then a SCSI and Ethernet
controller in the last slot.

Hmmm, I never thought about that. Maybe I should give my old friends at
the local Sun office a call.
