The IAPX432 came out the same year that the IBM PC came out which was 3
years after the 8086 and 2 years after the 68000.
It was slow and clunky compared to the 68000 and the 8086 was firmly
entrenched in the IBM-PC.
The 8086 used an extension of the very familiar 8080 instruction set and
the 68000 was modeled after the PDP-11 with it's orthogonal instruction set.
Though they both had their flaws (the 8086 more so than the 68000) the
IAPX432, by comparison, was too little, too complicated & too late.

They SHOULD have started with a clean sheet, of course.
I guess the iAPX 432 wasn't sufficiently "clean sheet" :-)
