Hi,
Regarding the FPU, I can only think of a handful of math-intensive software titles that used an FPU, stuff like hardcore statistical programs...this morning, I ran across an "Orbital Tracker" program, that would compute satellite orbits, circa 1992. It had two versions, an FPU version, and a plain vanilla, non-FPU version.
For those who *had* to run programs without an FPU, there was a workaround, called "Software FPU" that would emulate an FPU, via software (it was a control panel). Of course, it ran very slowly.
Unless you are an intensive hobbyist/do-it-yourselfer, I wouldn't bother switching an 68LC040 for a regular 68040. My LC 575 is perfectly happy with its -LC040 brain.
