It would be very complex. Emulator would need to emulate Motorola
co-processor low level interface commands, commands that are implemented
in hardware in 68020+.
AN947_REV0.PDF seems to be the only existing official Motorola memory
mapped FPU documentation. (Any search engine should find it)
I haven't bothered with it, there was no Amiga model with memory mapped
FPU but there was at least one hardware hack and I think there is either
1 or 2 programs that support it. Not worth the trouble.
