I had a look at bitsavers and was a bit surprised to see
that none of the 11/40 (11/35) engineering drawings or
field maintenance print sets are available there!
I needed some time to localize my 11/40 documentation ...
I have two sets of the engineering drawings of the 11/40,
one contains the KD11-A backplane wire list rev. C, the other
has rev. F. The set of course has the 11/40 CPU boards, and
also stack limit, line time clock, power harness, the workz.
The wire list is 17 pages (33 sides), Ledger format. I could
scan them given a few days (tomorrow I have a day off).
Can you look at the label / sticker on the side of the 11/40
backplane? Maybe it says which Rev it is. I don't know the
differences between rev. C and rev F.
