Yes but in classic Amiga + PPC card systems you are killing one processor to a allow the other to function. If you have to kill the 680x0 CPU for the 603/604 PPC to execute then how is that multi processor supporting OS?
This is one of the big reasons why PPC didn't sell to us, it was a competition between two kludge's to an OS that badly needed help from Commodore for the PPC era....who had decided to blow their last load on some crappy crippled CD console instead....
