Fred,
Please bottom post to keep the flow of the thread easy for digest members
to follow.. I.e. put your reply at the bottom of the previous post, and
trim out unnecessary text.

In order to assist you further we'd need more technical detail.  Is this a
stock 80/30?   Does the system attempt to boot at all?  Can you get to a
ROM monitor to run diagnostic commands of things like RAM contents, RAM
test?  Is the s100 backplane getting proper voltage? These kinds of details
help greatly because first we need to know if the issue is with the
computer, I/O card, ROMs, drives or something else.  We need to define the
point (s) of failure.

You may have to wait until someone with measuring tools can inspect this
system if you're not in possession of these things.
