I ran this ad back in 2015, will try again :)
I was going through my board collection and found three PDP-11 boards I've
never used in years and don't see a foreseeable need.
No idea of condition, but they're visually clean and neat, stored in
antistatic bags.
The serial cards came out of my working 11/23+ but I've not tested them
(since I already have a 16-line card and only 2 terminals).
I have (one each):
M7957 DZV11 Quad height 4-line serial card
M8053 DMV11 "Microprogram Control" synchronous controller card (looks
like it was intended for networking with 56k modems)
Dilog CQ1610 16-line serial card.
Make any reasonable offers. + shipping from US zip 65775.
thanks
Charles
