This is a project aiming to document the timeline of various versions of the CP/M-86 operating system, focusing primarily on those released for the IBM PC.

The various names of the operating system include CP/M-86, CP/M-86 Plus, MP/M-86, Concurrent CP/M-86, Personal CP/M-86, Concurrent DOS, DOS Plus, Concurrent PC DOS (not to be confused with IBM PC DOS), Concurrent DOS 286, Concurrent DOS 386, Concurrent DOS XT, Multiuser DOS (not to be confused with Microsoft's Multitasking DOS 4), and FlexOS.

For each version, the following information is collected into a table:

  • Date of release, or at least the year if unknown
  • Release name and version
  • Following patches to the release, if any (e.g. CP/M-86 1.1 for IBM PC XT)
  • BDOS version, as reported by function 12 (MRTVNO)
  • Specific API differences, if appliable
  • Present features, especially DOS filesystem support, DOS application support, and multitasking
  • Supported media types (e.g. fixed disk, 160k floppies, ...)
  • Links to preserved copies: source, binaries, and floppy images, both official and unofficial
  • Links to manuals (User's Guide, System Guide, Programmer's Guide), DRI manuals are good sources of information
