Is there any actual documentation on it emulating a 68020? I've read this in several places, although I've also read it emulates a 68040. I've also read it emulates a 68LC040 and relies on the PPC FPU which is slow in emulation, or something. I know I've run 68k programs on my PPC that require 68040 that work quite well, so I've always been a bit dubious about the 68020 emulation. It also seems like it'd be odd for Apple to do that when the whole reason for the emulation was maintaining compatiblity for recently-developed and widely in use apps.

So it does emulate a 68LC040 but reports itself as a 68020. I suppose it makes sense. It doesn't exactly emulate any given processor so whatever it reports itself as, some program or other will have a problem.
