## MC6809 CPU emulator written in Python

MC6809 is a Open source (GPL v3 or later) emulator for the legendary **6809** CPU, used old homecomputer [Dragon 32/64](https://en.wikipedia.org/wiki/Dragon_32/64) and [Tandy TRS-80 Color Computer (CoCo)](https://en.wikipedia.org/wiki/TRS-80_Color_Computer) built in the 1980s...

Tested with Python 3.8, 3.9, 3.10 and PyPy3

Run tests, e.g.:

```bash
~/DragonPy$ ./dev-cli.py coverage
# or just:
~/DragonPy$ ./dev-cli.py test
# or with different Python versions:
~/DragonPy$ ./dev-cli.py tox
```




### TODO
