tbd, boards I have or that I would like to have, with relevant info

Check Henk's board list for details.

PDP 11/44

Want/#Have Board Number Description
Want KE44-A M7091 11/44 CIS Control Store
Want KE44-A/2 M7092 11/44 CIS Data Path / Logic module
2 PF11-F M7093 11/44 Floating Point
2 KD11-Z M7094 11/44 Data Path module
2 KD11-Z M7095 11/44 Control module
2 KD11-Z M7096 11/44 Multifunction module
2 KK11-B M7097 11/44 4KWord cache module
2 KD11-Z M7098 11/44 UNIBUS Interface
4 MS11-PB M8743 512KB ECC RAM (AA)

PDP 11/10 (11/05)

Want/#Have Board Number Description
4 ????? G109C Control and data loops for H214, with 2 extra parity bit channels
0 MM11-L G110 Control and data loops for H214, without the 2 extra bit parts populated (same PCB as G109)
2 ML11-L G231E Memory driver for H214, 16K X/Y Selection, Current source, Address Latch, 8K Decode
4 MM11-L H214 8-Kword 16-bit memory stack (with G110 and G231) (replaced by H215)
4 KD11-B M7260 11/05 data path module
3 KD11-B M7261 11/05 control module, 2x revision E, 2x revision F
1 MM11-S - extension backplane which can hold a single MM11-L board set.

There was some confusion. The stickers on the bags with boards marked two G109 boards as G110, and the 1973 drawings also specify the G110 as part of the 11/05. Apparently both boards use the exact same PCB (which is marked as G109C), but the G110 leaves out chips for two extra "parity" channels (details from Gunkies).
