- 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.
