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.
The BA-23 has 3 "CD" slots (Q-bus only on A and B, CD interconnect on C and D),
and 6 "regular" Q-bus slots, with the Q-bus alternating from side to side.
IIRC, the BA-123 has 5 CD slots, the rest standard.
For anyone collecting FAQs, this is one. I can't recall how many times I've
sent out an ASCII drawing on the backplane. I with I'd kept one. :-(
