KT11-D Memory Management Unit
From Computer History Wiki
The KT11-D Memory Management was an option for the KD11-A CPU of the PDP-11/40 which provided memory management. It did not provide the full PDP-11 Memory Management, but the simplified subset.
It was a hex card (M7236) which plugged into a dedicated, pre-wrired slot in the CPU's backplane. The KT11-D required the KJ11-A Stack Limit Register option.
