RunCPM is an application which can execute vintage CP/M 8 bits programs on many modern platforms, like Windows, Mac OS X, Linux, FreeBSD, Arduino DUE and variants, like the Teensy or ESP32. It can be built both on 32 and 64 bits host environments and should be easily portable to other platforms. RunCPM is fully written in C and in a modular way, so porting to other platforms should be only a matter of writing an abstraction layer file for it. No modification to the main code modules should be necessary.
If you miss using powerful programs like Wordstar, dBaseII, mBasic and others, then RunCPM is for you. It is very stable and fun to use. RunCPM emulates CP/M from Digital Research as close as possible, the only difference being that it uses regular folders on the host instead of disk images.
RunCPM builds on Visual Studio 2013 or later. Posix builds use GCC/LLVM. It can also be built on the Arduino IDE. It can be built also on Cygwin (posix) and Mingw. Makefiles are provided with the distribution.
