The FastMath was about the worst product ever released by AE. The math chip,
a national Semiconductor, was so stupid it was hardly acting as a valuable
addition to the 65816.
The only capable math coprocessor were the Floating Point Engine and its
substitute Number Cruncher by, I think, Andreas Schmid. The Number Cruncher
had an edge over the FPE because it actually worked.
It is not correct that math cards were an useless add-on. Orca can compile
source code specifically for FPE/NC enhanced systems, the SANE patches
routed some math calls through the coprocessor, and lastly there are
programs that take advantage of the FPE. Ok, I can only think of one at
this time. Think tenfold speed increase with math routines.
