MEM11A Unibus Memory

The MEM11A unibus memory board is intended for older (ie non-MUD) unibus systems.  These systems were predominantly core based.  Its form factor (quad sized/SPC) was dictated by the desire to be able to use a memory board in an 11/20 chassis which is extremely difficult to find memory for since the 11/20 chassis cannot take the hex sized cards.
