Descriptive quote from the article: “Multics is a mainframe timesharing OS that started as far back as 1965 and was put to rest after a long life in October 2000. You may be asking why you need to know more about an OS that is no longer in use. The answer to that question is, “You’ll never know where you’re going if you don’t know where you’ve been.” Although this saying is a bit corny, it is especially true of Multics because of its influence on today’s mainstream operating systems.”
im personally of the opnion that architectually multics was the ultimate OS, plus from what i gather it should be possible to implment it on an intel setup because the only special thing about the old multics hardware was that it had paged and segmented memory, which these days isnt exactly rocket science now is it
