IIRC, in the USG 4.0 doc that I sent to Matt, it says something like "UNIX is an operating system for the DEC PDP-11, the DEC VAX 11/780, and the IBM System 370". Matt --- can you confirm? I can't get to my copy so easily. That document dates from 1981, and as it came from USG, it would mean that the AT&T UNIX on 370 was from that world and is what is described in the 1984 BSTJ. If anyone has the System III source handy, one could check if there is a u370 shell script and/or a u370 directory in the kernel source. (There used to be shell scripts named pdp11, vax, u3b, and u370 for use in shell 'if' statements, analogous to the C preprocessor defines.) If so, then UNIX 370 would date back even further.
