The many derivatives of the CP/M operating system - ChickenMan - 05-08-2022
I find this article a fascinating read of the story of CP/M from start to finish.

Thanks Chickenman!
Also you know there's also the official microbee variations - including the bog standard (with CCP) for the microbee 56, ZCPR (CCP replacement) for the microbee CIAB, microbee shell & OS mods for the microbee 128.
There's a whole bunch of user developed alternatives even including a MSXDOS derivative. (Yay! subdirectories!)
CP/M is essentially geared up for character based I/O such as ASCII terminals and printers. Some of the microbee variations instead use direct hardware access - e.g. 128K shell, MW DISK BASIC. Even Micropro Wordstar 3.3 is configurable for direct memory mapped VDU memory access for improved performance.
