Michal Tomek just released the beta version of the first and only Z280 emulator I'm aware of.
emulator also simulates the hardware of a Z280RC machine, meaning it
can be used as a development tool to test applications, OS ports, etc.
before uploading the code to the target system.
The CPU core,
MMU, DMA, timers, interrupts, traps, serial port and IDE interface are
emulated accurately enough so that all four operating system ports
available for the Z280RC are supported: CP/M 2.2, CP/M 3.0, RSX280 and
The emulator can be downloaded from https://github.com/mtdev79/z280emu
Builds under Windows with MinGW and under Linux.
