PDP-11/44 Boards

Something tells me this machine isn't going to be running anytime soon. Here is what I found when I got into the CPU. M7090 KD11-Z 11/44 console interface module M7093 FP11-F 11/44 floating point module M7094 KD11-Z 11/44 data path module M7095 KD11-Z 11/44 control module M7096 KD11-Z 11/44 multifunction module M7097 KK11-B 11/44 4-Kword cache module M7098 KD11-Z 11/44 UNIBUS interface M7762 RL11 RL01/02 disk drive controller M9902 M7762 RL11 RL01/02 disk drive controller M8256 RX211 RX02 floppy disk drive control module M7819 DZ11-A 8-line double-buffered async EIA with modem control (50 to 96-Kbaud, 64-byte silo) M7819 DZ11-A 8-line double-buffered async EIA with modem control (50 to 96-Kbaud, 64-byte silo) M7800 DL11 Async transmitter & receiver, 110-2400 baud Based on the info on the cover, the system is missing the following. M7091 KE44-A 11/44 CIS control store module M7092 KE44-A 11/44 CIS data path/logic module M8743 MS11-PB 1-Mbyte ECC RAM M7521 DELUA-AA UNIBUS to ethernet adaptor SPC BC11-25 TO TM11 I've no idea what the last three are, I suspect the 'TO TM11' is actually the huge ribbon cable that is plugged into the backplane. I'm assuming that without the M7091 and M7092 that there is no use in coming up with a RAM board. Zane | Zane H.
