This is a 387 / Weitek compatible chip, | boasting significant speedups. (Biggest speedup, of course, | is avoiding the coprocessor interface). Two questions: (1) since this is a plug-in replacement for the 80387, how does it avoid the coprocessor interface, and (2) in what way is it Weitek compatible? I haven't heard that it will run Weitek code, is this a typo or underpublicized feature? -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
