Multics was started in 1964 and first went online in 1967, although it
seems likely it wasn't exactly at the top of its game yet. Bell Labs
pulled out in 1969. If that was the 75% point, 100% would be around 1971.
Not to put too fine a point on it, It seems like it would be fair to say Multics was 'complete' by the time Organick published his book: "The Multics System: An Examination of Its Structure." Amazon says the 3rd printing was April 72, so that means he must have published it earlier. I don't know when it first appeared and can not seem to find it. My copy is in storage but I bet I have the 3rd printing. But I had >>thought<< that was still in the late 1960s. Anyone have a first edition around with the publication date?
