Herr Doctor Wkt:
Does anybody have a PDF of the 1974 Unix CACM paper, I seem to have
misplaced my copy.
=======
It appears to be generally available via the ACM Digital Library,
of all places. (No, I'm not so smart: Google pointed me there.)
http://dl.acm.org/citation.cfm?id=361061
It appears to be the genuine 1974 version, though my paper copy
of that issue of CACM is buried behind too many boxes right now
for me to dig it out and check. Disk storage for `The PDP-11/45
on which our UNIX installation is implemented' is as Warren
describes for the 6th Edition update: 1MB fixed-head disk,
four 2.5MB removable-cartridge drives, and a single 40MB
removable-pack drive.

I have heard the story a few times about sbin split is due to disk
space, such as told at
http://www.osnews.com/story/25556/Understanding_the_bin_sbin_usr_bin_usr_sb…http://lists.busybox.net/pipermail/busybox/2010-December/074114.html
But I don't see any mention of it in 32V and not in BSD until around
Net2 (like in 1991 src.README said ``... there has been a major
reorganization of the file system. (You may have seen similar
reorganizations on systems shipped by Sun Microsytems [sic] and Digital
Equipment Corporation, among others.) ... /sbin same as /bin, but
binaries for the root user''. The slides from Feb. 1988 for a BSD BOF at
USENIX mentioned this sbin reorganization.
Looking at "Unix Text Processing" (1987) and "Life with Unix" (1989) I
didn't see any use of sbin/. (I didn't look at my other old books.)
>From searching old 1980 usenet archives I only saw a few mentions (like
/usr/brl/sbin/...).
When did some (non-BSD) systems ship and document /sbin, /usr/sbin?
Is the common story (liked linked above) the right story?

What's so bad about stdio? That's a genuine question - I've never had
a reason to dislike stdio...

Just a few lines to announce that some of our historical
computers are back online 24/7 for free use!
We have 2 VAX/VMS systems and an emulated PDP-11/34 running
RT-11 (that's the exact copy of our physical RL01 boot disk)
Have a look here, and enjoy! :)

Hi. I have two QIC 6250 tape cartridges that have been in (I hope) dry
boxes for over 15 years. I suspect they're still usable but have no
equipment with which to test them or try to read them.
It'd be nice to get a CD back with copies of what's on them if that's
possible, but that'd be icing on the cake.
Drop me a note and we'll see if we can figure something out for mailing
them.
Thanks,
Arnold
On another list I am on, a discussion about the history and purpose of
strncpy has arisen. The only reference I have found to it is <
http://lwn.net/Articles/507432/>:
The original reason for strncpy() was when directory names were limited to
14 chars. The other two bytes contained the inode number. For that
particular case, strncpy() worked quite well.
Is that really the reason it came into being?
Just a bit curious,

Hi all,
Arnold Robbins has donated a couple of OpenLook CDs to the Unix
Archive. I've put them into Applications/OpenLook.
Here is his note:
I have a CD from ian(a)darwinsys.com dated 9/2005 with
OpenLook-XView-1.0e on it, and what looks like another one with
the same date with version 1.2. I'm still extracting the first
one onto disk; it's in the 550+ Megabyte range. Files are dated 1995.
Right now it's only on minnie until the mirrors pick it up:

Cheers & thanks Arnold & Ian,

Hi guys, new SIMH (and Research Unix) user here coming from the future
(Linux), haha. Well, as the mail subject says, I have a problem.
After creating a bootable disk from a virgin Unix v7 distribution tape by
following this guide, http://homepages.thm.de/~hg53/pdp11-unix/, and after
umounting the usr file system and halting the machine, SIMH returns:
HALT instruction, PC: 000002 (HALT)
after running the command:
pdp11 run.conf
and I cannot boot my 87,9 MB 'system.hp' disk.
I thought the problem was on the final line of 'run.conf':
run 2002
But when I use SIMH without .conf files and by manually typing the
following commands:
set cpu 11/45
set cpu 256k
set rp0 rp04
attach rp0 system.hp
boot rp0
I see the same HALT message too.
I'm currently unning SIMH from Debian/Ubuntu package 3.8.1-5build1. Should
I update to a newest one? Or did I make a mistake when creating my bootable
disk?
Hi,
Don't remember if this was already posted to this list, so, just in case
it wasn't...
The UNIX System: Making Computers More Productive
http://techchannel.att.com/play-video.cfm/2012/2/22/AT&T-Archives-The-UNIX-…
In the late 1960s, Bell Laboratories computer scientists Dennis Ritchie
and Ken Thompson started work on a project that was inspired by an
operating system called Multics, a joint project of MIT, GE, and Bell
Labs. The host and narrator of this film, Victor Vyssotsky, also had
worked on the Multics project. Ritchie and Thompson, recognizing some of
the problems with the Multics OS, set out to create a more useful,
flexible, and portable system for programmers to work with.
What's fascinating about the growth of UNIX is the long amount of time
that it was given to develop, almost organically, and based on the needs
of the users and programmers. The first installation of the program was
done as late as 1972 (on a NY Telephone branch computer). It was in
conjunction with the refinement of the C programming language,
principally designed by Dennis Ritchie.
Because the Bell System had limitations placed by the government that
prevented them from selling software, UNIX was made available under
license to universities and the government. This helped further its
development, as well as making it a more "open" system.
This film "The UNIX System: Making Computers More Productive", is one of
two that Bell Labs made in 1982 about UNIX's significance, impact and
usability. Even 10 years after its first installation, it's still an
introduction to the system. The other film, "The UNIX System: Making
Computers Easier to Use", is roughly the same, only a little shorter.
The former film was geared towards software developers and computer
science students, the latter towards programmers specifically.
The film contains interviews with primary developers Ritchie, Thompson,
Brian Kernighan, and many others.
While widespread use of UNIX has waned, most modern operating systems
have at least a conceptual foundation in UNIX.
Release date: 02/22/2012
