I'm trying to find out what 68k applications require an FPU.

By that I mean, what will refuse to run without one?

I'm trying to find the most basic 68k CPU that pretty much all OS legal software would run on and that seems like the 68020 with no MMU or FPU.

Thanks!


Hi,

An FPU (floating point unit) is mostly used for mathematical calculations, I really don't think a program will refuse to run with out one, it is just that it will take longer to make the math calculations. Spreadsheets and 3D rendering actually use an FPU if there is one available in the machine.

So ......

adding an FPU should make some programs run faster if they are coded to use it.

I have no idea what your talking about, so here is a doggy with a small pancake on his head.

MorphOS is a MAC done a little better
