I've finally reached the stage of my PDP-11/35 restoration where I'm
ready to turn it on and debug logic.
A copy of the PDP-11/40 Maintenance Printset would be INCREDIBLY
helpful, as would a bus extender and a KM11.
Ideally, I don't want to buy these - this is a one-off project for me,
I'd really like to borrow them for about 1-2 months and then return
them. I'd be happy to pay a "rental" fee, even.
I'm located in the SF Bay Area, if someone local can let any of these go
for a little while, I'd be quite grateful.
Thanks!

Hi Seth,
I have both, but they might take a while to find. If you don't need
them for a while, I can ship them to you when I find them.
Do you know for fact that the cpu has problems? Or the memory? I would
try to find a copy of the Unibus Troubleshooting Guide and go through
that if you haven't. If you have options, KT11, KE11, KF11, etc you
might want to pull them for now and check all the jumpers.
I might have a board set you could use if that would help.
Thanks, Paul

Well... you caught me, I don't actually know :) I haven't tried to power
the system on with the cards installed yet. I've spent the past month
and a half just taking everything apart down to the last screw, cleaning
everything, getting the chassis professionally sandblasted and powder
coated, and repairing the power supply.
So the fact is, I have no idea, and I may be jumping the gun a little.
But on the other hand, I'd frankly be shocked (SHOCKED, I tell you!) if
it worked on the first try, given the state of the computer when I
received it. It had been exposed to very rough conditions for a long
time.
Now that the power supply is fully repaired and everything has been put
together and tested WITHOUT boards, I plan on doing my first power-up
WITH a minimal set of boards tomorrow evening. Fingers crossed.
