Well, I've done it again.
This time, I went all ~1400 miles to San Diego. I've been saving my money
for this one, and it paid off nicely. I picked up:
* PDP-11/20 -- According to the owner, this one worked last time it was
booted (no idea when that was), and I should expect the monitor to still
be loaded in the core.
* PDP-11/20 -- Not known to be in working condition. Missing a few
switches up front and maybe a few boards inside. Basicaly, a spares
machine. The faceplate is the older one that just says "PDP11" instead of
"PDP11/20", and I'll probably transplant it to the working machine for
that reason.
* PDP-11/05 chassis -- In great condition, but with no boards. Anybody
have a set up for trade?
* TU56 -- Looks to be in great condition.
* TC11 -- Looks to be in great condition.
* DECtapes -- About 100 of them. I think there's an operating system and
a fortran compiler in there somewhere.
* A few printsets.
I'd like to find a couple of RK05 drives, maybe a PCxx paper tape
reader/punch, and their controllers to round out this system. Anybody
have any of these up for trade?
Considering that all this was free to a good home and that it fit in the
back of the Suburban I borrowed from my parents, this has turned out to
the be least expensive haul this summer. All in all, I'd say that this
summer has been very successful.

I'd say make *IT* the working system and use the working system as the
parts machine. Don't just transplant the faceplate!

Sweet!

I won't tell you how many years it's taken me to locate a papertape
reader/punch, and it's for a PDP-8/e I'm getting.

Me, too. My furthest haul was Columbus to Louisville for a PDP-8/L with
high-speed punch/reader, ASR-33 and BM-08. It's what I show off to visitors.

Nice. I'll be glad to hear how your restoration work goes. As I've mentioned
elsewhere, I have the parts of an 11/20 that was chopped up and disposed of
before it got to me (PSU cables cut, etc). I have most of the core (some
was scavenged by cow-orkers), all of the CPU and 3/4 of the BA-11s. It's
way down on the list of thing to fix, but I did at least save the parts from
the dumpster after my supervisor threw it all out, piece by piece.
Something _I_ have that you might be interested in is a full set of original
printed docs, color covers and all. About 10-12 prints.
Missing a few switches up front...
Speaking of which, is there a good subsititute? I have some broken PDP-8/L
switches - the plastic pivot pins snap off when people bump past the console.
I was planning on melting/drilling the broken ones and fashioning a replacement
metal pivot. Anyone with any suggestions?

working system as the
parts machine. Don't just transplant the faceplate!
I agree. It's a modular system. Should be easy to fix if you keep the
boards together in a block (I'd consider removable adhesive labels or
perhaps light pencil marks in the margin of the board, away from any traces)

Excellent. I also recently landed some of that stuff, too. We should
trade a tape inventory. I couldn't save most of the tapes due to
company policy of the donor, but there was a box of them in the base
of the cabinet that was overlooked.

I might be able to help you out there. I have to see what I have in
the way of RK05 stuff. I know I have drives and packs. What I'm
not sure about is controllers. My first RK05 drives (one good, one
very dead) came with an RK11C. I have never even fired it up. My
next RK05 came with an RKV11D. It works, or at least it did the last
time I fired it up (years ago). Mostly, I use RL drives; not period
for the 11/20, I know, but they were cheap and available when I got
into all of this.
I won't tell you how many years it's taken me
to locate a papertape

I'd love to get an OMNIBUS controller. I have the punch/reader (along
with one set of pre-OMNIBUS cards for my PDP-8/L and -8/i).
