A multi-tasking, multi-user operating system introduced in the late 1970's for 8 bit computer systems based around x80 microprocessors, it was basically a multi-user version of CP/M and could run the bulk of, but by no means all, of the software written for that operating system. 16 bit versions of the system were introduced in 1981 but MP/M was later replaced by Concurrent CP/M.
