I agree, hunting the manuals and schematics could take awhile. The
hardware seems to be around. Just need to snoop around for a large site
deinstallation, could be a lot of these in the next few years. The sad
part is in the late 80's and early 90's I put into the dumpster a bunch
of this stuff.

Yep... As I've said to a few people : "I'd not recomend a PDP11/45 as you
first -11, an 11/05 or something is a lot easier to start out with. But
_I_ started on an 11/45 because that's what I was offered".
I'm mostly looking for documenation now,
which might take some time to
track down.
Well, although I've mananged to obtain a couple of shelf-fulls of PDP11
docs and (especially) printsets, it wasn't that easy. I've spent a good
few years hunting for old manuals, geting and repairing 'scrap' boards,
etc.
My first PDP11 (the 11/45) came with no peripherals at all. Not even a
DL11 console port. Oh, there was an RK11-C, but no RK05s to link to it.
I got the printsets but no user manuals, so I didn't have a clue as to
what the instruction set was. Oh, and there was no memory. I was given a
MUD card (I didn't know what it was called) but no backplane. First job
was to modify the only DD11 I had to take an MUD RAM card.
It took me nearly a year to find a DL11 and some disk drives. In that
time I'd managed to borrow a DEC microprocessor handbook - the 11/23
instruction set was near enough to let me write programs. And then I
obtained a few handbooks, a DZ11, a few more prints, etc. Finally I got a
disk unit, a couple of DL11s, some realtime I/O cards, etc.
