Right. Everything is prewired in the backplane. And there is just one

Wire Lists for any/all of the following:
KB11-C 11/70 Processor (or the older KB11-B)
FP11-C 11/70 Floating-point processor (or the older FP11-B, also used
in 11/45 and 11/50)
RH70 MASSBUS controller
I don't know for sure about the 11/70 (I never looked at one closely), but
for the 11/45 FPP, IIRC that was part of an integral multi-unit backplane
assembly with the CPU, i.e. it was wired as part of a large wire mat that
included the wiring for the CPU. So I don't think there's a separate wire
list for the FPP. I would guess the same is true of the RH70. DEC generally included the wire lists in the
engineering drawings; do the
11/70 prints not include the wire list?
I think I remember seeing the wire list in there, but it's been many
years since I read through the 11/70 prints.
