Would anyone outside Motorola who has actually seen a 68881 please post word to that effect? Many people have seen 32081s (well, 16081s before the Great Renumbering). For that matter, I note that the 68881 timings appear to have been calculated, rather than measured -- the line-eater bug got the early part of the intro, so I'm not certain -- and thus should be taken with a large bag of salt. Real Soon Now chips *ALWAYS* look better than ones that are already available... I don't doubt that the 68881 is going to be a superior chip, especially since it has full IEEE functionality instead of the drastic subset that the National chip implements. I just wish Motorola would stop talking about it and start selling it. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
