From mboxrd@z Thu Jan 1 00:00:00 1970 From: helbig@Informatik.BA-Stuttgart.DE (Wolfgang Helbig) Date: Sat, 14 Apr 2001 17:01:45 +0200 (CEST) Subject: [pups] Ken_Welsch_v6 and Dennis_v6 Message-ID: <200104141501.f3EF1jO03450@RVC1.Informatik.BA-Stuttgart.DE> Hi, I'm referring to the Ken_Welsch_v6 description in http://minnie.cs.adfa.edu.au/TUHS/Archive/PDP-11/Distributions/DETAILS The Ken Welsch tape differs from the Dennis disks only in the "RESTRICTED RIGHTS"- statement that was put into /usr/sys/ken/main.c on October 10th 1975 EDT. The binaries that depend on this change, were rebuilt (usr/sys/lib1 and the kernels in /) and thus show the same modification date. All other files from the Ken Welsch tape bear a timestamp between May 14th 1975 and July 18th 1975. After installation from the Ken Welsch tape onto a (simulated) RK-disk the date(1) command displays: October 10 12:29:51 EDT 1975 (which in Australia is October 11th. That might explain, why the dates given in the DETAILS file are off by one) Wolfgang Received: (from major at localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id BAA16087 for pups-liszt; Sun, 15 Apr 2001 01:46:27 +1000 (EST) (envelope-from owner-pups at minnie.cs.adfa.edu.au) Received: from mailhost.cs.uofs.edu (mailhost.cs.uofs.edu [134.198.169.1]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id BAA16083 for ; Sun, 15 Apr 2001 01:46:23 +1000 (EST) (envelope-from bill at cs.uofs.edu) Received: from triangle.cs.uofs.edu (IDENT:root at triangle.cs.uofs.edu [134.198.172.101]) by mailhost.cs.uofs.edu (8.9.3/8.9.2) with ESMTP id LAA20966 for ; Sat, 14 Apr 2001 11:39:59 -0400 (EDT) Received: from localhost (bill at localhost) by triangle.cs.uofs.edu (8.9.3/8.8.6) with ESMTP id LAA21339 for ; Sat, 14 Apr 2001 11:38:20 -0400 X-Authentication-Warning: triangle.cs.uofs.edu: bill owned process doing -bs Date: Sat, 14 Apr 2001 11:38:20 -0400 (EDT) From: Bill Gunshannon To: PUPS Mailing List Subject: [pups] PDP-11/24 -- BA11-A help needed Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-pups at minnie.cs.adfa.edu.au Precedence: bulk Is there anyone here with experience working on a PDP-11/24 in a BA11-A box??

So I would gather from your detective work that based on dates, this tape just predates that provided by Dennis Richie by such a short time? I do know that the physical paper label on the tape was hand written.

I do know No, the other way round: The tape you provided is from October 10th and the disk image provided by Dennis is from July 18th. The "RESTRICED RIGHT"- remark was put into the kernel on October 10th. It is on the tape that you provided, it is not on the disk image from Dennis. But the source code from the Lions book shows this remark as well. I don't know who changed main.c on October 10th 1975 (I lived in Israel at that time) You see the remark only if you set the switch register on the PDP-11 to a nonzero value befor booting. I installed V6 from the tape following the setup instructions. With the Supnik simulator, enter sim > d sr 1 sim > boot rk0 @rkunix And it will print your rights! Wolfgang
