On 80287 performance:  I just benchmarked some code that we wrote in Lattice
C 3.1 with and without the 80287 chip.  The actual execution time was the same
both ways, although the exact split between the two sections of the program
was different.

                           Byte shuffling      Calculation
With 80287                     6 sec              5 sec
Without 80287                  5 sec              6 sec

This was run on an ATronics 12 MHz AT with the 8MHz 287.
