Tony has a good point here: it's usually the support stuff (power supplies,
connectors) that bugger up a machine of this simplicity. -- Ian

Subject: Re: looking for a working 11/05 (KD11-B) board setu
My 11/05 was not working when I bought it and I would like
to find a known good board set so that I can verify functionality
of the rest of the machine and then possibly diagnose the defective
board set.
Does anyone have a known good KD11-B board set (M7260, M7261) which
they would be willing to part with?
I rteally don't see what goof a working processor board set will do...
What is the machine doing or not doing? Have you checked all the power
lines (at least the +5V and -15V) at the backplane? Can you do anything
from the front panel? Read/write memory?
