The MD-10 was a core main memory system for the early PDP-10s, principally the KA10. An MD10 could contain up to four 32KW memory modules, for a maximum of 128KW. The cycle time is 1.8 μseconds. It connected to the so-called external memory bus of the 18-bit address form.
It was a multi-port memory, with 4 ports per memory system: the CPU uses one port (in a multi-processor system, one per CPU); the others are used by channels (such as a DF10) for mass storage such as disks.
