MP/M (Multi-Programming Monitor Control Program) is a discontinued multi-user version of the CP/M operating system, created by Digital Research developer Tom Rolander in 1979. It allowed multiple users to connect to a single computer, each using a separate terminal.

rdfs:comment	MP/M (Multi-Programming Monitor Control Program) は、CP/Mをマルチユーザ化したオペレーティングシステム(OS)である。デジタルリサーチ(DRI)の開発者・が1979年に開発した。MP/Mが動いている1台のコンピュータを、それぞれ個別の端末から複数のユーザが同時に使用することができる。 MP/M は、少なくともマイクロコンピュータ上では、その時代としてはかなり高度なOSだった。MP/Mのカーネル（カーネルという名前が使われる以前は、nucleus（核）と呼ばれていた）は、メモリ保護、同時入出力(XIOS)、スプールとキューイングに対応した優先度スケジューリングされたマルチタスクカーネルだった。また、各ユーザが複数のプログラムを実行し、それらを切り替えることできた。 (ja) O MP/M (Multi-tasking Program for Microcomputers ou "Programa Multitarefa para Microcomputadores") foi a versão multiusuária do sistema operativo CP/M, criado pela Digital Research, Inc. Ele possibilitava que múltiplos utilizadores se conectassem a um único computador, cada um utilizando um terminal separado. (pt) MP/M (Multiprogramming Monitor for Microcomputers) va ser la versió multiusuari del sistema operatiu CP/M, creat per Digital Research i desenvolupat per Tom Rolander el 1979. Permetia a múltiples usuaris connectar-se a un únic ordinador, utilitzant cada un d'ells un terminal. MP/M era un sistema operatiu bastant avançat per a la seva època, almenys en microordinadors. Incloïa un nucli multitasca basat en prioritats. També permetia a cada usuari executar mútiples programes i alternar entre ells. Igual que abans va passar amb CP/M, MP/M va ser portat a l'Intel 8086, amb el nom MP/M-86.

El sistema requería un mínimo de 32 kB de RAM para funcionar, pero esto dejaba muy poca memoria para aplicaciones de usuario. (es)
