According to my understanding, you can't get a F-line exception on
68040.
The F-line exeception vector is used for all FPU illegal and
unimplemented insns.
Thanks - now from my reading of the fpsp040 code (which has mislead me 
in the past), it would seem that operations like sin() and exp() ought 
to raise that exception then. I don't see that in ARAnyM.
Is there any emulator that correctly emulates the 68040 FPU in that regard?

Cheers,
