The MS750 Memory System consists of:

  • one Memory Controller (MCM)
  • one to eight Memory Modules

The Memory Controller is a CMI Module, either L0011, L0016, or L0022 placed in CMI Slot 10.

The Memory Modules have their own backplane with 8 slots.

VAX-11/750 Memory Controllers

There were three different Memory Controller Modules for the VAX-11/750:

L0011

  • for up to eight M8728 256K Memory Modules = 2M max.

L0016

  • for up to eight M8750 1M Memory Modules = 8M max.

L0022

  • for up to two M7199 4M Memory Modules and six M8750 1M Memory Modules = 14M max.

14M of Memory are the architectural limit of the VAX-11/750.
