MC6809 0.4.0

MC6809 CPU emulator written in Python

MC6809 is a Open source (GPL v3 or later) emulator for the legendary 6809 CPU, used in 30 years old homecomputer Dragon 32 and Tandy TRS-80 Color Computer (CoCo)…

There is a simple benchmark. Run e.g.:

~$ cd MC6809
~/MC6809 $ python2 ./MC6809/cli.py
~/MC6809 $ python3 ./MC6809/cli.py --help
~/MC6809 $ pypy ./MC6809/cli.py --loops 20

You can run unittests in different ways, e.g.:

~$ cd MC6809
~/MC6809 $ ./setup.py test
~/MC6809 $ python3 -m unittest discover
~/MC6809 $ ./MC6809/cli.py tests --verbosity=3 --failfast
