In response to my query about the Cyrix CX486SLC chip, I've 
received a couple of very informative messages explaining in
detail the differences between the Cyrix chip and the Intel 486
family.  Although the chip does implement the 486 instruction set
there are differences in cache size and use of some registers,
which does not seem to affect most current software but reportedly
does keep NextStep from running on this processor.

The labeling of this chip as a 486SLC tends to imply that it's a
clone of Intel chip with the same label.  It's interesting to note
that different computer vendors handle this chip differently;
Tandy labels its notebook with this chip as a 3xxx machine, 
whereas its Intel 486-based models have 4xxx designations.  (Which
seems to imply they think of it as more a 386 clone than a 486).
By contrast, CompuAdd in its latest catalog pitches their
425XL notebook as a "486 at a 386 price!".  Caveat emptor.
