Gee, if the 68020RC12 wasn't an off-spec part it would run at a maximum
clock freq of 12.5MHz, not 12.0...  Same thing for the 'RC16 - max clock
is 16.7MHz (actually the minimum clock period is 60ns....)

Seriously, watch out for the minimum frequency too - it's 8MHz for both
the '12 and the '16.

Good luck finding a cheap co-processor - supply/demand/production volume/
yield/etc. isn't on the consumer's side at this point.
