- I don't know about NT, but here's some info on NeXTSTEP 486 from the
- NS486 Q&A:
-
- : Will NeXTSTEP 486 run on 386 machines?
- : No. NeXTSTEP 486 uses several 486 specific features that enhance
- : the performance of NeXTSTEP. NeXTSTEP 486 will support any true
- : 486.
- :
- : Will NeXTSTEP 486 run on the Cyrix 486SLC?
- : No. The Cyrix chip not a true 486.
-
- IMHO, if there are in fact processor-specific advantages to requiring
- a 486, doing so makes sense. The PC world has long been crippled by
- its need for backward compatibility with early machines. This seems
- a good point to start with a clean slate (or as clean a slate as
- possible).
