Actually, I suggested something like this quite a while ago, when some
Intel bigshot had mumbled in public about soon being able to put four
CPUs on a single chip and what can we possibly do with it all.  If you're
Intel, it's obvious:  one 860, one 486, one 80960, and fill up the last
slot with odds and ends like 8080, 8008, 4004, 2920, etc.  Then you at
last have compatibility among Intel CPUs:  one chip runs software for
any of them!
