Can anyone tell me what these cards from a DEC PDP-11/04 are? I've identified some them but I'm not they're correct. (1) M2763 (2) H-222A (16k x 18 core memory) (3) H-222A (16k x 18 core memory) (4) Advanced Control Corp. card with two FMI (Function Module Inc) 9685 Digital to Analog Convertors (5) same as 4 except it has two Burr Brown DAC-800-CBI-V convertors (6) M7856, (7) M9312 (Boot Strap Terminator? Exactly what does it do and why does it have four terminals on it?) (8) M7228 (KW11-P Real Time Clock). Joe
