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.
Bill Shen's Tiny68k is a 68000 board with 16M of RAM and a 68681. The emulator supports the rev2 board:

Additional resources including CP/M images can be found on the rev1 page:

Fetch the Tiny68K monitor / debugger for v2 and CF CP/M disk image and run:
./py68k.py --target tiny68k --diskfile t68k_cpm_disk.bin --eeprom T68kbug_r07.BIN
Bill Shen's P90MB features a Philips P90CE201 68070-based system-on-chip, 512k of flash, 512k of RAM, I2C and three RC2014 slots.

Fetch the EPROM file with monitor, CP/M and BASIC, and run:
./py68k --target p90mb --rom loader1_5+EhBasic+CPM.BIN
Another Bill Shen board, CB030 is a minimal 68030 system.
This emulation has some serious issues due to limitations in Musashi's MMU emulation.
Python, with vt102, pyelftools and hexdump modules installed.
