I've been back and forth on t= he naming, I hear it called USG UNIX 4 in some contexts, the literature jus= t says "UNIX" until SysV which gets "UNIX System". UNIX/TS is at the top o= f low.s in SysIII and SysV, but this could just be left over. In one school of thought, calling it PWB 4 might be more accurate than any = of these. I recall reading elsewhere here in the mailing list that the nam= e System III was chosen because it was believed Programmers WorkBench would= n't be an appealing name marketing-wise. If strictly documentation is to be followed, then this manual and my analys= is represent "UNIX Release 4.1" for the 3B20S as dated June 1981. Anything= not directly pertaining to this, of course, is speculation and postulation= . - Matt G. ------- Original Message ------- On Thursday, February 9th, 2023 at 6:54 PM, Jonathan Gray w= rote: > On Thu, Feb 09, 2023 at 01:32:21AM +0000, segaloco via TUHS wrote: >=20 > > Good day everyone, I'm emailing to start a thread on part of my larger > > UNIX/TS 4.x project that is coming to a conclusion.
