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)…

Tested with Python 2.7, 3.4 and PyPy

A example usage can be find in: MC6809/example6809.py

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

~$ MC6809 benchmark --help

# run benchmark with default settings:
~$ MC6809 benchmark

# run with own settings:
~$ MC6809 benchmark --loops 10 --multiply 20

(MC6809 is the cli installed by setup.py)

Unittest use nose, run them, e.g.:

~$ cd MC6809
~/MC6809 $ python2 setup.py nosetests
~/MC6809 $ python3 setup.py nosetests
