It *IS* a 486.  It just has a 16KB write-back cache (normal 486s are
8KB write-through) and can be run 4x clock, where "normal" 486s are
1x-3x.

There they are, in all their glory. :-)

I ran one for a few months.  It worked fine.  Be aware that it's a
3.3-volt part, and if you're plugging it into an old motherboard, you
may need a 5v-3v converter.
