I agree that IBM should have used the Z8000.  However, I know that Zilog could not 
have produced enough working chips.  In the 1981-1982 period we had a hard time 
getting enough working chips for our own internal use.  The ones we got were much 
faster than the 8086 though.  Our Zeus (Unix) systems made MS-DOS on a PC look slow.  
OTOH even our Z80 system was faster then a PC.  I think we were making 6MHz Z80s in 
1981.  I think our Z8000s were 6MHz or 8MHz.

Yeah. I've got some round here: they're in the early Macs. I've also got
a newer version of it (SMT) inside a JTEC terminal controller. It's a
single-board computer, the sort of thing we'd have mortgaged our home for
in the early 70s.

The Zilog Z8000 was another big-endian CPU. A shame, I think, that IBM
didn't use it instead of the 808x. My brain is definitely big-endian,
and MASM confused things even worse by printing its bject code in
"human-friendly" big-endian format with the result the object code
printed was not what was actually generate.
