Well, it depends on whether QRT is compiled using IEEE functions so that
the 68881(2) will be able to cruise... You can notice a decrease in the
amount of time that it takes to calculate with the processor at 14MHz.
I believe that I was getting in the area of 80% or so increase in speed
when I was doing the preliminary tests on the Accelerator.
