What requires an FPU?

[Heiroglyph]

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!

Yes, just to clarify:

I don't care what can optionally take advantage of an FPU.

What won't run without one?

Thanks

I wouldn't worry about speed, this isn't a real CPU.

It's going to be an emulation, but not the overkill for my use UAE JIT.

If you ignore all the unused parts and have no timing constraints, you can make a pretty fast processor in a shorter period of time.

It's somewhere between an 030 and an 040, minus the MMU and FPU at this point and I hoped to put off writing the FPU if possible.

UAE is already available and specialized for those cases, I'm only worried about OS legal applications.

I think I've got enough info to go on at this point.  I don't think I'll have to do the FPU.

Thanks.

Looks like you might need to emulate a keyboard
