Like CP/M, MP/M was eventually ported to the 16-bit [[Intel 8086]], and appeared as '''MP/M-86 2.0''' in September 1981.<ref name="DRI_1981_MP/M-86"/><ref name="MP/M_1981_UG"/><ref name="MP/M-86_1981_PG"/> Main developers of the system include Francis "Frank" R. Holsworth<!-- born 19??-09-04 https://amaus.net/static/S100/software/DRI/Digital%20Dialogue/03x04%20198408%20Digital%20Dialogue.pdf (using [[siglum]] FRH -->,<ref name="Wein_2002"/><ref name="Holsworth_2006"/> later a director of marketing at Digital Research. Known revisions of MP/M-86 2.0 were dated 25 September 1981 and 5 October 1981. There also was an '''MP/M-86 2.1''' dated 20 July 1982.<ref name="MP/M-86_2.1"/>

MP/M-86 2.1 absorbed some of the technology of [[CP/M-86 1.1]] (BDOS 2.2) to become '''Concurrent CP/M-86''' 3.0<ref group="nb" name="NB_CCPM"/> (BDOS 3.0) in late 1982,<ref name="Kildall_1982_8-bit"/> which also added support for "virtual screens".<ref name="Kildall_1982_8-bit"/> [[Kathryn Strutynski]], the project manager for CP/M-86, continued as project manager for Concurrent CP/M-86. In December 1983,<ref name="DRI_1984_PCMODE"/> a DOS emulator named [[PC-MODE]] became available as an optional module for Concurrent CP/M-86 3.1 (BDOS 3.1), shipping on 21 February 1984,<ref name="DRI_1984_CCPM31"/><!-- TBD. To be verified that this actually refers to CCP/M-86 3.1, not CCP/M-80 3.1. --> and the system was further developed into the [[MS-DOS]] compatible [[Concurrent DOS]] (BDOS 3.1 and higher).<ref name="DRI_1984_CDOS31"/> This in turn continued to evolve into [[FlexOS]] and [[Multiuser DOS]] and as such is still in use in some industrial applications.

Concurrent CP/M is often abbreviated '''CCP/M'''.<ref>
