Too much noise and irrelevant or ignorant posts. However, unfortunately
I don't have any better suggestions where to go if you are trying to
restore old hardware and don't have enough knowledge.
And yes, I keep lots of different PDP-8, PDP-11 and VAXen running,
including 11/70 systems.

I had an 11/70 service manual as an ebook at one stage, it had full
schematics etc, you also have access to various simulators to help you
understand the programming interface so i can't see what other info you
would need for your restoration, maybe you'd need help jerry rigging some
setup to get an initial tape written to get u started?
If you have any questions about the schematics or electrical
troubleshooting I'm happy to help although I have never owned a physical
pdp11... concepts are the same as any more modern system.
cheers, Nick

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.
