==Later development==
In 1975, the computer was rereleased with no changes as the MCM/700.<ref name=":0" /> Also released that year were a punched card reader, [[plotter]], and several programs. The MCM/800 followed in 1976. It was faster, included 16&nbsp;KB RAM, and included the ability to drive an external monitor. [[Virtual memory]] was supported on all of the machines, although using cassettes for storage made it slow.

Released in 1978, MCM/900 was faster yet, included 24&nbsp;KB RAM, and an included a monitor. The MCM/1000, also called the MCM Power was a repackaged /900, and was later repackaged again as the MCM MicroPower. The bigger change for the /900 and /1000 was to support the HDS-10 disk [[Server (computing)|server]], which included an 8.4 [[megabyte|MB]] 8-inch [[Shugart Associates|Shugart]] [[hard drive]], an 8-inch floppy disk drive, and a 64 k [[Zilog Z80]] to control it. Up to eight /900s or /1000s could be plugged into the HDS-10.
