A future version of the Cyrix chip can use the Weitek interface (that is, the memory mapped addresses the Weitek occupies) -- but it will not be Weitek code compatible. So you could get comparable speed to a Weitek chip, but only if the code were recompiled for the Cyrix logical interface. > bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) > "The world is filled with fools.
