From c15320b6d90e408861037e473f8bb9e7f748d487 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Sat, 20 Jun 2020 04:07:44 +0000 Subject: [PATCH] Correct 1BSD release date. The Quarter Century of Unix book said that 1BSD was released March 1979. However, the 1BSD tape image that's on Kirk's historical unix collection has an earlier date. It was common practice, at the time, to create a new copy of the tape from the master system when a new tape was to go out, so several different versions of 1BSD, etc were shipped from Berkerely. The date on the 1BSD tape in the Berkeley archives on Kirk's DVD is dated in January 16 1979 on the label, and has dates as late as Jan 29 (there's an UPDATE file that says this includes updates through this date). Note this date as well. --- share/misc/bsd-family-tree | 1 + 1 file changed, 1 insertion(+) diff --git a/share/misc/bsd-family-tree b/share/misc/bsd-family-tree index 58684f71651e..30aa25fe45fb 100644 --- a/share/misc/bsd-family-tree +++ b/share/misc/bsd-family-tree @@ -477,6 +477,7 @@ Ninth Edition 1986-09-xx [QCU] Tenth Edition 1989-10-xx [QCU] 1BSD late 1977 + 1978-01-16 [DOC] 1978-03-09 [QCU] PDP-11, Pascal, ex(1) 30 free copies of 1BSD sent out
