I definitely recall hearing that IBM management considered that a 16-bit bus, with its bigger circuit board connectors and all, would be too expensive for a "personal" computer, so it had to use an 8088 (or 68008, or 6809?) rather than 8086 or 68000. This is really humorous when you remember that IBM originally charged close to $2K for the big iron-cased PC! Hard to imagine 16 bits being any bulkier or costlier.... -- Mike Knudsen Bell Labs(AT&T) att!ihlpl!knudsen Round and round the while() loop goes; "Whether it stops," Turing says, "no one knows!"
