- aside from the already known different memory paths and lack of
- coproccessor (but gee, these are such minor differences :-) ) that's
- it, but this was obvious from the initial cyrix specs
-
- someone posted a while back with the differences (instruction/data
- wise) between a 486 and a 386/387 and showed how it would be easy
- enough for someone to write an os that would only work with a 486 be
- exploting 486 features
-
- and when you consider that the cyrix chip is essentially a very fast
- 386sx, the differences between it and a full 486 are obvious
-
- what i want to know is whether NS486 will require a 487 if you have a
- 486sx
