I looked at my early Multics stuff, and it's "Multics" almost everywhere: - "GE-645 System Manual", GE, 1968 - "The Multics Virtual Memory", GE, 1970 - "Introduction to Multics", MIT MAC TR-123, 1973 However, in my "A New Remote-Access Man-Machine System", on the title papge it says "Reprints of the MULTICS system presented at the" [FJCC, 1965]. No clue as to who printed it, or when - and all the FJCC papers themselves use "Multics". I have yet to ask Jerry Saltzer, but I suspect that if it ever was 'MULTICS', it was at a _very_ early stage, and was formally changed even before the FJCC papers (which were themselves very early). BTW, ISTR hearing that it was 'Unix' originally, and the 'UNIX' spelling was adopted at the insistence of Bell lawyers. So I went looking for an early (i.e. PDP-7 era) scanned document, to see what it was then, and all I could find was: https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/UnixEditionZ… which seems to be from just after the PDP-7 -> PDP-11/20 transition, and it uses 'UNIX'. Would the Bell lawyers have already been involved at that stage? Noel
