This costs money. A lot of money. Last I checked, a complete Amiga cost less than a single 68030. When you're already making heavy use of a silicon foundry to cut your parts count... Besides, I said "you have to add more processors". Not "you have to add special purpose CPUs". People have been using 68000s and other CPUs as I/O processors for years. -- Peter da Silva, Ferranti International Controls Corporation, sugar!ficc!peter.
