Try cvrmach at gmail.com. He has some 11/05 stuff he is likely willing to sell at
reasonable prices. I did some diagnostic work on some 11/05 boards a couple of years ago.
Suggest you refer to my name (Jay) in your message. Runs a machine shop - not a
collector. Name is Clarance Raalte (not sure of spelling - on tablet right now)

A PDP-11/05 in need of some help arrived on my doorstep
yesterday.
Amongst its other problems (*) the power/panel lock microswitch has been
broken beyond all repair and it's kind of an oddball thing -- anyone
happen to have one going spare (or know what the equivalent might be?).
Someone did a rather ugly kluge to work around it (it's just hotwired in
an always-ON configuration with a really ugly jumper wire), and I'd like
to get it operating normally again.
It's marked as DEC P/N 12-10982 (REV. B).
Thanks in advance,
Josh
(*) It's been dropped (or had something dropped on it), the frame is
bent as a result, which I've mostly undone. The power supply tests out
good (a small amount of ripple but within tolerances if the service
manual is to be trusted) and it shows signs of life (Load Addr works
about 50% of the time), however it's not doing much. The M7261 board
has "BAD?" penciled in so someone else's been over this machine before.
I sense a lot of debugging in my future.
