Well... the Cyrix '387 clones are pin compatable, are *much* faster than the
'387.  From what I've read of the cycle counts for the Cyrix chip and the
'486, the Cyrix is faster than the "487" as well.  (Unfortunately, you have
to use it in "memory mapped" mode, a la Weitek, because of the way the '486
was designed.)

If/when Cyrix does a '386 clone, I hope it has similar speed advantages over
the Intel chips as does their FPU clones...
