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.
