+bcombee Posted November 8, 2020 Share Posted November 8, 2020 While brainstorming other features for the FujiNet hardware, I stumbled upon https://github.com/MockbaTheBorg/RunCPM/, a MIT-licensed CP/M 2.2 emulator that already runs on the ESP32. Given that the FujiNet already does drive emulation, buffers printer output, and acts like a serial port, CP/M mode is the last bit of functionality needed to do everything that the ATR8000 did. I don't know enough yet about the memory usage of the FujiNet core -- RunCPM needs 64K for the CP/M system memory, plus additional RAM for running the Z80 emulation. The ESP32 port was done using the Arduino support, so it would need to be ported to PlatformIO as well as changed to use SD card code that FujiNet already has internally. Does this seem viable? Interesting? 1 Quote Link to comment Share on other sites More sharing options...
