Making the I/O co-processor a requirement could quickly make the
price of the board sky-rocket, if we're not careful. It is nice to
consider these options in the hope that we could find something that
would be cheaper to add. I don't think that a 6809 would fit this
bill. Consider that we could add a R3041 (R300 for real cheap) to
do this for us$15 (plus the glue), but what is the justification?
An idea, one chip that could cover both of the above requests could
be the TI34010 graphics CPU. Last I checked you could get them at
around us$30 (that was a year ago).
