I keep thinking about putting together a 6809-based machine, just
for the fun of it.

I also converted the included postscript file into a PDF.
Something like the CMU Free6809 board would be great, but I'd
prefer to add a CRT coltroller to get a video display. I'd
also want a keyboard interface so that the machine could
be independent of a terminal. Maybe even a disk interface
of some sort, and the AY-3-8910 sound chip, and a parallel
port, and... Oh dear, now I'm making it too complicated!
What do other people think about a small-scale 6809 board?
