The 68302 is not that likely.  If I remember rightly it will cost most
of $100 (I should check that).

As for sound, I was thinking of that, but something that could be somewhat
useful to the DSP guys.  This would mean at least a 30KHz variable sample
rate DAC with a variable filter;  This is starting to smell of creeping
featurism.

Optional sound would be nice, but only if no sound is zero cost.  I'd still
push for ISA slots for that kind of thing.  How hard can it be -- the Mips
machines have ISA slots.
