He said creating a card that had, say, a 1.2ghz Intel Atom on board that emulated any of the m68k family at a blistering pace was no problem.
Cept someone would have to write the emulation. Existing m68k emulators could be the basis but all the I/O do not really exist. Wont be a 10 min thing.
Of course, getting such a beast to interface with the archaic, arcane and downright cryptic ins-and-outs of Amiga circuitry...that's another matter altogether!
I bet it is financially not-viable.
