- The head of NeXTSTEP 486 development dropped by the WaNUG meeting last
- Wednesday, and gave us a short presentation on the upcoming product
- and there was a Q&A session afterwards.
-
- The answer to your question is that NS 486 uses a few 486 only instructions
- for speed. Therefore any 486 that implements *all* of the Intel 486
- instruction set will work. This means that the Cyrix 486SLC will not,
- since that's just a 386 with a built in cache (several PC columnists
- have mentioned this, and the confusion it causes). If the IBM
- fully implements the 486 instruction set, then it will work. If not,
- then it won't. I know that IBM has the license to alter/manufacter
- the 386 chip... I don't know if IBM has rights on the 486. It sounds like
- the IBM 486 isn't a real 486.
-
- I haven't had a chance to post a report on our Q&A session... I might get
- around to it tonight. (hopefully)
