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?
