I have a DG AViiON-100 on my desk. Even though it is a 16.67 MHz 88k, DG
insists on calling the box a 17 Mips machine.  Xcalc gives me 115/4=28.75
so I'm guessing that the marketing types are being a little more honest
and refering to a 33 MHz 88k as a 28.75 MIP processor, (unless they
are calling a 25MHz 88k a 29 MIP processor :-). Otherwise I have no info 
on this machine.
