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.
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:

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?
I'd say make *IT* the working system and use the
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
reader/punch, and it's for a PDP-8/e I'm getting.
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).
