It depends on how you count bits. 16 bit data bus, 24 bit addresses, but any comp org textbook will tell you that the 68000 has 8 32-bit general purpose data registers and 8 32-bit address registers, and most of the instructions operated on 32 bits at a time. If you really want to say a processor is n-bit when it has an n-bit data bus, be my guest. But then most PCs become 64-bit, which I don't think you agree with. -Tom
