[edit]Actually lots of companies have used object-code interpretation in a similar role. I know the HP used it when they moved from their HP3000 minis over to the HP-PA RISC systems for instance. IBM used it to run S/370 apps on the RT as well. In fact, I think there's about a dozen common examples of this.
Where it is?
[edit]As far as I know, the emulator is included in the system ROM, as Apple documentations talks about the PowerMac ROMs saying that about between 1 and 1.5Mb are the 68k emulator while the rest are the ROM itself (that were made of OF, the emulator, and the 68k Toolbox that runs in the emulator).
When moved to NewWorld (8.5 onward) enough part of the core MacOS was PowerPC native so the emulator can be inside the system software (and was removed from ROM along with the 68k Toolbox in B&W G3 onward)
