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-M Quad height 4-line serial card M8053 DMV11 "Microprogram Control" synchronous controller card Dilog CQ1610 16-line serial card. Make any reasonable offers. + shipping from US zip 65775. thanks Charles
