M68K emulator based on Musashi, with a Python device model
Launch the console server with py68k.py --console-server. This provides vt102 terminal emulation for the console serial port. The console server will stay alive across multiple runs of the emulator.
Launch the emulator itself with py68k.py --target <target-name> [<target-options>]. You can pass
--help with or without --target; if passed with, additional target-specific help may be printed.
py68k has a flexible device and target model that makes supporting new targets relatively easy.
See devices/ for some device examples, and targets/ for corresponding targets.
The simple target is primarily for emulator testing, though being very simple it's also a good
target for hosting software development. See devices/simple.py and targets/simple.py.

- zBug seems to work
- uClinux failed to boot for now : Need to fix the ticker's device andi/or interrupt handling.
