CP/M-86 Timeline
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.
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
The CP/M-86 history documentation project channel on Discord is the chat associated with the project, you can join it if you are interested in helping out.
