another interesting bit of trivia is that when IBM built the first "PC", for
the first time they chose off the shelf parts instead of proprietary IBM
stuff. Zilog was in the hunt for the Z80 processor, but they were late to
develop one with the 16 bit bus, so Intel got the nod.  If Zilog had won
out, they would be the 800 pound gorilla!

        Nope, the 8086 was the first x86 processor, the 8088 was
functionally
identical except it had an 8 bit external bus so that existing 8 bit parts
could be used (which were much cheaper than 16 bit wide parts). TTYL
