The KT11-C Memory Management Unit is the memory management option for the PDP-11/45. It implements the full PDP-11 Memory Management architecture; in fact, the KT11-C is the archetype for PDP-11 memory management units.
The KT11-C consists of two hex cards:
- M8107 Segmentation Address Paths
and either:
- M8108 Segmentation Status Registers
or:
- M8108-YA Segmentation Status Registers
The M8108 board is found in the KB11-A CPU variant of the -11/45, and the M8108-YA in KB11-D CPU variant.
They both plug into pre-wired slots in the CPU backplane.
When the KT11-C is not present, the CPU must have an M8116 Segmentation Jumper Board present instead.
