The dates blur in my mind, but I think uucp was around in the Labs long before V7.  Might not have been distributed, though. There was a long history in the Bell System of collecting data by phone -- Model 33 teletypes could be left in a mode where a phone call could wake it up and turn on the paper tape reader, and the data could be collected at the other end.  (Remember when long-distance calls were expensive, but much cheaper at night?). This reminds me of a story from that era.  One of the mainframe computers had the ability to place phone calls and a program was run every night to collect data from far-flung teletypes.   The phone call would go through, the modems would synchronize, and the data would be passed.  On day the operators realized that there were two phone numbers in Nebraska that were getting called every weekday night, and the numbers were very similar.  They suspected one was a wrong number, so they listened in on the calls to see which one was real.   The phone rang in Nebraska at 2am and was answered by a sleepy man, with whom the modem cheerfully tried to synchronize.  The man was heard to say "It's all right, Bertha.  It's just that nut with a whistle again!" ----- Original Message ----- From: "Dave Horsfall" <dave(a)horsfall.org> To:"The Eunuchs Hysterical Society" <tuhs(a)tuhs.org> Cc: Sent:Wed, 8 Mar 2017 14:45:49 +1100 (EST) Subject:[TUHS] UUCP mis-history? http://www.thefullwiki.org/UUCP ``UUCP was originally written at AT&T Bell Laboratories, by Mike Lesk, and early versions of UUCP are sometimes referred to as System V UUCP.''
