Amiga hardware at that point was played out, we are better off with modular components instead of a few chips that run everything that cannot be changed without something breaking. The Amiga started off a major leap ahead and ended up ancient left behind by everything else.

The mac emulator should be fun to play with, I have a XT bridgeboard in my A2000 thats kind of cool (and you get to use the built in ISA slots for cards in it).
