well, I think you should hear this from a long time Mac user.... from the
days of the Mac Plus......

there 2  versions of the 68040 used in the Macintosh. The 68040 and the
68LC040. The LC version has a disabled/broken fpu which means it doesnt
work. The one you use will depend on the type of 68k Mac you have... You
have a Quadra 900 or 950 then you have an 68040 with the 68881 fpu (math
co-processor/floating point unit). the non-fpu will run on your machine
but it will run slower than the version with the fpu. Csound is fpu
intensive. So, get the fpu version if you have a Quadra 800, 900, 950 and
some 650 machines.... the Mac IIci (68030)also has an fpu. Note that you
can add an fpu to most old Macs (LC, LCII, LCIII, color classic, SE, si,
etc.....)

you could run the non-fpu 68k version on a PPC, but why would you run any
version of the 68k binary on an PPC?

On PPC under 68k emulation the fpu version will not even run unless you
have an fpu emulator installed.... note that the UMAX clones shipped with
the PowerFPU emulation extension so you could run the fpu version on these
PPCs.... but again why? it would be slow as hell....
