Why do you need a 387 to run X11R3?

When I cut my teeth, unix systems without FP hardware did the
emulation thing in library routines that were 10 to mayby
100 time slower than hardware, so a program that would spend
10% of its time doing FP would slow down by less than ten times.

For the amount of FP I do, I can live with that.

Unfortunately, the 386 sysV unixes do their FP in the kernel by
taking a trap on the unimplemented intruction.  This is _real_
slow.  Slow enough that simple awk scripts can take hours to
slog through a few hundred K of input.  Get the '87 -- its
cheaper and easier than wishing you had until you do.
