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?
