The last machines I ever saw where schematics were
available to the
end users were the VAX-11/780 and the uVAX-II. The 780 schematics
were as thick as a phone book and 11 x 17" pages. The uVAX-II
was a lot smaller, it was a hierarchical description, but gave a lot
of insight on how the processor and interface chips were organized.
The 11/750 and 11/730 also had full schematics and assembly drawings
on thick slabs of 11"x17" paper, accompanied by several 8.5"x11"
tomes
of technical descriptions. I think even DEC stopped providing that
level of documentation in most cases after about 1983 or so.
I remember plenty of detailed Qbus docs but I don't remember running
across the uVAX-II printset. That would be interesting to review.
