Hello all,
I've just received this mail from SCO. I think it's appropriate to
post here.
Apparently we can expect the Ancient UNIX License available on the
SCO website by Friday (U.S. Pacific Time, I would suspect). Very
good news indeed!

V2 mv(1) manual says files can't be moved across filesystems. V3 mv(1)
manual doesn't say either way. V4 mv(1) manual says the file will be
copied and the original deleted. V5 mv(1) source code exec's cp(1) when
the destination is on a different filesystem.

So wait. I need some clarification here. When you say V2, V3, V4, etc..
do you mean 2nd Ed, 3rd Ed, 4th Ed Unix?

Actually, the URL SCO used to use, http://www.sco.com/offers/, doesn't
have the license anymore. So I assume they are rearranging their site.
Here are some excepts from my SCO contact as to what they _might_ do:
What we basically want to do is:
1) Waive the $100 fee for the source code.
2) Make our portion of the source (by separating it from DEC's etc.
etc.) available from our web site, while still leaving it available on
yours. We would still like to refer people to you if they would like
other source code or would like to purchase a CD
3) Make the license agreement available online with a click through in
order to eliminate the paperwork. (We would probably just e-mail you the
people who have agreed to the license for your records)
We will however require that people "click through" our
site (or possibly yours) to gain access to your FTP site and media
distribution. We will consider any person that accepts the license
agreement from our site a "license holder".
I'm currently working on an automatic mechanism which would allow a person
to click-agree to the on-line SCO license (whenever that occurs), which
would give them access to the UNIX source code via SCO's web site, and
also password-protected access to the PUPS Archive here.
*** Note the Archive contains stuff that SCO doesn't own, e.g Ultrix,
the BSD releases, but which still require a UNIX source license.
For all those who haven't bought an Ancient UNIX license from SCO, if
you can I would hang off from ordering one until the web mechanism
arrives. It will save you and SCO the time & delay of processing paperwork.
If you _really_ require a license, and are prepared to wait 6 weeks,
then go to http://minnie.cs.adfa.edu.au/PUPS/getlicense.html to get a
copy of the license. Post it to SCO, but don't send any money!!
Hope this helps,
Warren

Hi all,
It's time to call again for volunteers to help out with the
distribution of the PUPS Archive. In particular, if you have received
a CD of the archive within the last 9 months, and you can duplicate it,
then please let me know if you are willing to distribute a few CDs a month.
We have a need for people in Asia, Japan, Australia, South America, but
I'll take anybody anywhere!
Many thanks in advance for your offers.
Cheers,
Warren
Warren is right that even the First Edition manual says that init
mounts /usr, implying that /usr was a distinct file system even that
early. It seems to me that the original question Greg forwarded
from the NetBSD list was also after when /usr/bin appeared, which
isn't necessarily the same date.
A possible answer from old manuals:
- Second Edition sh(I) (dated 3/15/72):
If the first argument is the name of an executable file,
it is invoked; otherwise the string "/bin/" is prepended
to the argument. (In this way the standard commands,
which reside in "/bin", are found.) If the "/bin" file
exists, but is not executable, it is used by the shell
as a command file.
- Third Edition sh(I) (dated 1/15/73):
If the first argument is the name of an executable file,
it is invoked; otherwise the string "/bin/" is prepended
to the argument. (In this way most standard commands,
which reside in "/bin", are found.) If no such command
is found, the string "/usr" is further prepended (to give
"/usr/bin/command") and another attempt is made to execute
the resulting file. (Certain "overflow" commands live in
"/usr/bin".) If the "/usr/bin" file exists, but is not
executable, it is used by the shell as a command file.
Notice the odd detail that non-executable files in /bin (early on)
or /usr/bin (later) get special treatment. Does this mean that
shell scripts that weren't in /usr/bin had to be invoked explicitly
via `sh script' instead of just `script'?
Even deeper historic trivia: it occurred to me to check the fragments
of the PDP-7 system I have on paper to see whether /usr existed then.
I was quickly reminded that it almost certainly didn't because subdirectories
weren't really used then; there were no pathnames in that system.
(You could open only files in the working directory, though you could
link from another directory.) When asked to invoke `x', the shell first
tried to open `x', then to link `x' from directory `system' and open the
result. (Presumably it remembered to remove the needless link after the
open, but I'm not quite certain; the old paper copy is missing a few
lines just there.) So even the name `bin' doesn't date back quite to
the beginning.

Can't tell, we don't have the source code. In the Nsys kernel (dated
just before the 4th Edition), files must have the execute bit on or
they can't be exec(2)d.

I've tried running the image in /Boot_Images/2.11_on_rl02 on
Supnik's emulator version 2.3d, but the root filsystem seems
corrupted, with many binaries being unexecutable, bad block
error messages, etc.
Does anyone know how to successfully boot this image?
If this is the wrong place for this kind of question, or if
there's a FAQ on this, then please point me in the right
direction.

Hmm, if I get a chance I'll try it here. Has anybody used this image
successfully?

Yes. The problem is not with the images (although the whole "on rl02"
is a pain - you're far better off using the "xp" or large disk support
that Bob added).

This is a very good place to ask this type of question.
And now the moment you've been waiting for: "the Answer" ;)
2.11BSD is *very* upset at having to run in 256kb of memory. since
the kernel plus buffer cache (and other data structures) can easily
exceed 200kb there is not enough memory left over to run a program.
Programs such as 'fsck' are fairly large split I/D programs and won't
fit in the remaining ~56kb or so.
The quick fix to the problem is adding the line:
set cpu 2048K
to the config file before running the simulator. That will give the
simulated PDP-11 2Mb of memory which is a real nice size. Oh, if
memory is a concern on the system then "set cpu 1024K" will work
well. Since there's no networking involved 1Mb will be quite adequate.
If you were using "P11" (the Begemot emulator) and had the full IP/TCP
stack, etc then the kernel+networking+buffers can reach close to 400Kb
and you might want to use 2Mb for the memory size.
You might also look into the latest version (2.5) of the Begemot
emulator. The two key advantages of P11 are: 1) a emulated DEQNA so
you can place the PDP11 on a network, 2) It keeps _good_ time
(version 2.4 and earlier had severe timeskew when running compute
bound programs, 2.5 is awesomely better and within range of "ntp"
to keep the clock correct). P11 also supports (as does Bob Supnik's
simulator) large disks such as the RP06 which is much nicer than
4 RL02s and a batch of RK05s.
Hmmm, I'm not sure which rev level of 2.11BSD is in the "on_rl02"
images - I hope it has the "bounce buffer support" to handle the 18bit
RK controller on a 22bit bus... If the RK images show corrupt or the
kernel crashes then I would suspect the kernel is a bit too old.
Unpack the "211bsd_on_rl02" images from the .gz images, edit the
"script" file to increase the system memory and you should be all
set to go.

The answer is: UNIX had / and /usr split by at least the time of the
July 1974 CACM paper ``The UNIX Time-sharing system''.
Here is the evidence:
At http://minnie.cs.adfa.edu.au/PUPS/Images/ken-and-den.txt and
http://minnie.cs.adfa.edu.au/PUPS/Images/ken-and-den.jpg
you will find a picture of Ken and Dennis at the PDP-11/20 around 1972.
The commentary in the text file from John Holden tell us that the disk
drives are RF-11 and RK03 drives.
RF-11 drives were fixed head drives with 512K of storage with fast access.
RK03s and RK05s could store 2M, but were not as fast as RF-11s.
The source code to (nearly) 3rd Edition UNIX, dated August 31, 1973, only
has drivers for two disks, RF-11s and RK05s. This source code is in the
PUPS Archive, http://minnie.cs.adfa.edu.au/PUPS. You need a Unix src license.
Now, the July 1974 CACM paper says this:
In our installation, for example, the root directory resides
on the fixed-head disk, and the large disk drive, which contains
user's files, is mounted by the system initialization program; ....
To me, this strongly indicates that / and /usr were split by at least
July 1974, if not the earlier date of August 1973.
Cheers all,
Warren

I just found some more evidence. The 2nd Edition UNIX manual is dated
June 1972, but the actual man pages have their date of last modification.
The manual for init(7), dated 15th June 1972, says:
[ If console switches are set to 173030, a shell is attached to the
console immediately, i.e single-user mode ]
Otherwise, init does some housekeeping: the mode of each DECtape
file is changed to [read-write] (in case the system crashed during
a tap command); directory /usr is mounted on the RK0 disk; directory
/sys is mounted on the RK1 disk.

Warren

And more, from the 1st Edition init(7) man page dated 3rd November, 1971.
Directory usr is assigned via sys mount as resident on the RK disk.
and sys mount means the mount(2) system call.

Hi all,
I'd just like to welcome the new people to the PUPS list. This
is probably the first e-mail in the list for a few weeks. I've been pretty
busy at work, but there is some interesting news on the old UNIX front.
+ SCO has now sold over 220 old Unix licenses, and I have something like
120 license holders with access to the on-line PUPS Archive. We've lost
count of the number of CDs produced by the PUPS Volunteers (thanks guys!)
+ I've got some Y2K patches for Unix coming in from Alexey Chupahin in
Russia. Once I get them sorted out, they will be put into the archive.
+ The baton of old Unix at SCO has been passed from Dion Johnson to David
Eyes and now to Paul Kaspian, their Open Source Marketing Manager. There
will be some changes to the Ancient UNIX license. If you haven't bought
a license, I would recommend NOT sending in any money just yet.
This will be good news, but I'm waiting on SCO to announce the details.
I'll keep you all informed as usual.
Cheers,
Warren
P.S the Minix operating system has been released under a BSD license. Anybody
want to port it to the PDP-11 family?
Someone is offering me an 11/23 with (I think) 2 small disks
(RL-something) which are meant to bbe 10Mb each (maybe 5?)
Can someone tell me what Unices this will run? It has no media other
than the disks (it has, I think, RT-11), but I've read about people
getting stuff into things down a serial line -- how practical is that?
Thanks

I saw the following on the linux-vax list. It seems to me it might be
worthwhile for us to get more info on the scope of the project, its terms,
and to see if we can collectively contribute to it. We'd all benefit from
having better access to old DEC documentation.

The Dallas/Fort Worth DECUS local users group is scanning all Digital
documentation, no matter how old. You might contact them
(denton(a)dsserv.com or wisniewski(a)dwlug.decus.org) to see if they'd like to
copy your manuals.
You get a free copy of everything they've scanned when they finish.
