From my memory, the other things that stand out about the i486:
	* call and return now take significantly fewer clock cycles.
	* the on-chip fpu is much faster than the 80387.  It was unclear

I belive the bus structure for the i860 and i486 is the same.

What support chips for the i486 and mc68040 were announced?
