I arrived at Bell Labs Piscataway, into Rudd Canaday’s PWB/UNIX department October 1973, same week our PDP-11/45 got installed, 2nd one in BTL after ken+dmr’s. We ran UNIX V4 of course, first one whose kernel was in C.
We even got documentation besides man pages: the CACM article & ~20-page C reference, which i still have.
