MM11 refers to a number of different core main memory systems for UNIBUS PDP-11s:

The first through fourth were multi-board systems which plugged into a custom backplane which was cabled into the UNIBUS. Some PDP-11/05 CPU backplanes could hold board sets of the later ones. The MM1-U board set was used in the MJ11 memory system for the PDP-11/70's Main Memory Bus. The last plugged into a Modified UNIBUS slot.
