The 11/70 service manual is all good, but it's definitely not enough.
Ideally, you should have access to the full drawings, the service manual
for the CPU, the service manual for the memory subsystem, I seem to
remember that the FP11 has its own service manual, and I think the
massbus interface also has its own documentation set.
Also, the memory system consists of both the Unibus map, the cache and
memory bus system, and they you have separate documentation for the
memory boxes (either MJ11 or MK11 box).
I don't know how much documentation have been scanned, and I haven't
really checked. Since I still have access to all the documentation on
paper I usually use that.
I don't even remember all the manuals and drawings that exist.
