Heh - just about the first 'real' thing I did in Python, back around 2001
or so, was to write a 'Device Driver' library to allow direct access to
memory-mapped I/O via Python. It compiled under both Windows and Linux
and I proved it using an ISA I/O board with loads of 8255s and LEDs
hanging off it.

As well as a learning exercise it was sort-of intended as a first step
toward robotic control using Python. I hopen to rework it for similar
PCI-based I/O boards (to do the sort of thing you mention), but never got
a round tuit...
