Thanks to Harald Baumgartner, Johannes Schibl and the inimatable Tom
Blinn. Harald suggest that the motherboard probably needs replacing,
Johannes thinks it's the power supply. Dr. Tom said to look in the
Service Manual which reminded me that Dave Huffman sent me that as a
Windows help file a few months ago for a similar problem on a Model 600.
Basically, the service manual says that if verifying all the connections
doesn't help (system module, I/O module, power cables, MMBs and SIMMs),
then you need to replace either the system module or the I/O module.
Well, folks, this machine has been going for over eight years, so if
"reseating" doesn't help, we will just lay it to rest.
Regards,
Peter
