'''CP/M-86''' is a discontinued version of the [[CP/M]] [[operating system]] that [[Digital Research]] (DR) made for the [[Intel 8086]] and [[Intel 8088]]. The system commands are the same as in CP/M-80. Executable files used the relocatable [[CMD file (CP/M)|.CMD file format]].<ref group="nb" name="NB_CMD" /> Digital Research also produced a multi-user multitasking operating system compatible with CP/M-86, [[MP/M-86]], which later evolved into [[Concurrent CP/M-86]]. When an emulator was added to provide [[PC&nbsp;DOS]] compatibility, the system was renamed [[Concurrent DOS]], which later became [[Multiuser DOS]], of which [[REAL/32]] is the latest incarnation. The [[FlexOS]], [[DOS Plus]], and [[DR&nbsp;DOS]] families of operating systems started as derivations of Concurrent DOS as well.
