Editing CP/M (section)

=== Compatible ===
Other CP/M compatible OSes were developed independently and made no use of Digital Research code. Some contemporary examples were:

* [[Cromemco CDOS]] from [[Cromemco]]
* [[MSX-DOS]] for the MSX range of computers is CP/M-compatible and can run CP/M programs.
* The [[Epson QX-10]] shipped with a choice of CP/M or the compatible TPM-II or TPM-III.
* The British [[ZX Spectrum]] compatible [[SAM Coupé]] had an optional CP/M-2.2 compatible OS called Pro-DOS.
* The Amstrad/Schneider CPC series 6xx (disk-based) and PCW series computers were bundled with an CP/M disk pack.
* The [[Husky (computer)]] ran a ROM-based menu-driven program loader called DEMOS which could run many CP/M applications.
* ZSDOS is a replacement BDOS for CP/M-80 2.2 written  by Harold F. Bower and Cameron W. Cotrill.
* CPMish is a new FOSS CP/M 2.2-compatible operating system which originally contained no DR code. It includes ZSDOS as its BDOS and ZCPR (see [[ZCPR|earlier]]) as the command processor. Since Bryan Sparks, the president of DR owners Lineo, granted permission in 2022 to modify and redistribute CP/M code, developer David Given is updating CPMish with some parts of the original DR CP/M.
* LokiOS is a CP/M 2.2 compatible OS. Version 0.9 was publicly released in 2023 by David Kitson as a solo-written Operating System exercise, intended for the [[Open Spectrum Project]] and includes source code for the [[BIOS]], [[BDOS]] and [[Command-line interface]] as well as other supporting applications and drivers. The distribution also includes original DR Source code and a utility to allow users to hot-swap OS components (e.g., BDOS, CCP) on the fly.
* IS-DOS for the [[Enterprise (computer)|Enterprise]] computers, written by Intelligent Software.
* VT-DOS for the [[Videoton TV-Computer|Videoton TV Computer]], written by Intelligent Software.
