Thank you for the comments Joe.I am aware(even more now!) that clock speed is
not everything.For instance one has RISC computers with relatively slow clock
speeds with high MIPS/MFLOPS ratings.There is the cycle/instruction issue as
you have alluded to.However,the 68881/68882 are very good math coprocessors
which function at their best if they BYPASS SANE.I don't no if the FPE does
that.(no->know).For floating point operations clock cycles aren't that
important.The speed of the coprocessor is however.

A good way of seeing what happens is to generate a Mandelbrot set.Even then
you would have a problem as the GS has fewer pixels to worry about than a
MacII.Would you have any reference indicating timing for such operations with
the GS(+TWGS+FPE).
