I spent part of the morning troubleshooting my BA123, turns out that I
didn't have a blown powersupply <whew>, instead I had managed to short the
power plug that goes to the TK-50, got that fixed, and it powers up just
fine. So I then pulled out the MicroVAX II CPU, memory, and some other
boards, and turned it into a PDP-11/23 :^)
However, I'm finding myself fighting the path that 'snakes' through the
backplane. Would someone be kind enough to explain it to me? I wish DEC
had done like SMS did and print it on the case! It's real easy to add and
remove Q-Bus cards from my SMS-1000's. I'm interested in both the BA23 and
BA123 backplanes.
