Roger,

You are correct but you should also remember that the 68881/68882 helps a lot
on the numeric stuff.  Send me the C code for the above benchmarks and I'll
run them with the FPE in my GS with a 7 mhz transwarp and post the results
for comparison.  As a very rough rule of thumb would you say a 65816 computes
at about half the speed of a similarly clocked 68030?
