Warren,
<assuming I [ have RT-11/ RSX / no operating system ] on the PDP-11 already
This is the tough part as PDP-11s run a wide variety of OSs. If you have
RT-11 (most common) you likely ok. But even then it can influence you
choice of devices. IE: RTv4 knows nothing of TK50 and RQDXn controllers
and v5.1 does. This is true for RSTS and RSX too.
The other is how to get it onto the required media. CDrom is largely PC
hardware. If the disk is readable using dos/linux it's fairly easy, though
the right supplied utility can help if not. PCs with the right hardware and
software can create RX50 and RX33 media, TU58 has been done, RX01 with more
effort. SCSI disk are not common on PDP-11s so that is a low yeild path
though they also can be done. The PDP-11 world peripheral wise divides
across what bus you have Q or U and that influences what peripherals you
likely to have.
The how of taking one of those binaries and moving to the PDP-11 has eluded
me for a while. I have been told it is not possible as they are image files
and if you copy an image of an RL02 to an RL02 you better have then same or
fewer bad blocks as the image may land on one making it useless.
I have been going through some of these gyrations with netBSD for the VAX
and they have set of problem that would be common to PDP-11. Check out
their FAQs on this for hints and solutions.

Warren,
I think you are exactly correct when you say these are the first two
eminent, and imminent questions about PDP-11 Unix. They have frequently
occurred to me as I drool in anticipation over the possibility of
running 2.11BSD on an 11/73!
Maybe you or a 2.11BSD expert (Steve Schultz?) could find the "release
notes" for 2.11BSD and post them, if that's legal now. That would
answer a lot of questions about how to configure a machine or whether a
particular machine could handle it. Maybe the release notes from two or
three different versions could cover a great majority of potential
users; your survey might answer that.
It will be great to have everything on a CD-ROM, but that probably won't
help a majority of users bootstrap up a system, since most won't have a
CD-ROM or maybe even no operating system to start with. We are going to
have to find someone(s) who is (are) willing to make up a standard
distribution tape (9-track or otherwise) or floppies (is that
possible?). This could really be the biggest hurdle to getting a system
running on many machines.

For my 11/34A with 2 RL01 I made with an emulator a bootable V7-RL01-diskimage.
I downloaded it under RT-11 with KSERVE from John Wilson (dunno where I
ftped it) over a serial line onto the second disk. It took some hours,
but it worked.

All,
While I'm thinking of it, does anybody have any old Usenix, EUUG,
AUUG etc. newsletters, papers, conference proceedings? Some of these have
details about fitting various UNIX flavours onto various PDP-11s, plus other
useful information. Anyone care to scan stuff in?
I've got some AUUG newsletters dating from 1980 onwards. One of them mentions
a `Heriot-Watt stripped down 7th Edition', which looks like it comes from
Heriot-Watt University in Edinburgh, UK. Does anybody have any knowledge of
this version of 7th Edition?

Sorry for the misunderstanding Allison!
Actually, that's a very good question. As I'm not a hardware person, I'll
pass this over to the other PUPS mailing list members. If/when SCO start
selling licenses & we make CD-ROMs or FTP sites available, this question
is going to come up an awful lot:
Question 1
----------
How do I get a Unix distribution onto:
- a tape, because I have a tape drive
- a disk drive, as I don't have a tape drive
assuming I [ have RT-11/ RSX / no operating system ] on the PDP-11 already.
Question 2
----------
I have [ this particular CPU and this list of other peripherals ].
What version(s) of Unix can I run on this PDP-11?
Can anybody help out with answers to Question 1? Bits & pieces of Question 2
are answered on the PUPS web pages, but they need expanding.
Thanks in advance for any information, and any programs (boot code etc)
that I can add in to the PUPS archive!!

Hello,
Curiousity, How does one get a license for a PDP-11 version of unix these
days? I've had an 11/73 I've been itching to run unix on.

Robert, I forgot to cc my reply to the others on the PUPS mailing list.
Would anybody in the US be able to look at Robert's tapes to see if we
can recover System III? John Holden just donated System V to the PUPS
archive, so System III would also be a good addition.
Please email to Robert & the mailing list if you are willing to look at
the tapes.
Thanks in advance,

7th Edition runs fine on an 11/23 or 11/34, providing you build the

As owner of a PDP-11/23+ system, I know how difficult it can be to find
hardware for older PDP-11's.
I'd like to inform you that I've found a terrific source in Utah for
used DEC hardware including PDP-11 related items. This person has a
2400 sq ft warehouse (about 3 semi truck loads) quite literally brimming
with computer hardware which has been collected and stored over the past
10 years. He is currently in the process of liquidating it at very,
very low prices. Tons of miscellaneous computer equipment is available,
much of which was manufactured by DEC. It would be impossible to list
even a fraction of what he has available, but he has told me that his
inventory includes approximately 1000 Q-Bus and Unibus boards, plus
peripheral devices such as disk and tape drives. I've not been to the
warehouse in person yet , but I will be visiting the site in about 2
weeks time from now.
If interested, you should be aware that he is in the process of getting
rid of EVERYTHING! It sounds like it will all be gone in the next 3 to
4 weeks.
Opportunities like this very seldom come along, so please contact me via
email if you are interested in finding out more. I'll be happy to
forward to you, any needed information that I can.
Please feel free to forward this notice to anyone you think might be
interested.

All,
I've just moved the PUPS (old PDP-11 Unix) mailing list over
to run under MajorDomo. I'm still learning MajorDomo, so there might be
some teething troubles.
The new list is called:
pups(a)minnie.cs.adfa.oz.au
Can you update any aliases that point to this list. I will keep the original
/etc/aliases mailing list oldunix(a)cs.adfa.oz.au around for a while
until I'm sure the new one works fine.
As with MajorDomo, you can send messages to get off the mailing list.
Please let me know of any problems.
Updates: SCO Petition, CD-R writers etc.
----------------------------------------
Ok, we're still chatting with SCO. I got a summary of internal mail which
shows that there are 2 sides in SCO, those who think it's a good idea (PR-wise
at least) and those who can't see the point & who think it's a can of worms.
I feel that the people on our side are winning. I've been trying to explain
the history of some of the UNIX flavours to their legal eagle, who must know
recent history only. I think we can iron things out.
Several people from Europe & the US said that they had access to a CD-R
writer, & could write CDs, if that became the distribution method for
passing on the PUPS archive.
I will probably go buy a new X-Gig disk to give the archive a proper FTP
home. I've come up with a new archive layout & will pass it on to you all
for comments. Anyway, it looks like progress is being made & we should be
able to buy personal UNIX licenses soon :-).
More updates to the list as things happen. Thanks for your suport!!

I don't think you'll get Unix running on an /03, I just searched thru the
paper archives here and I've seen references to /23's, /34's, 40's on up,
but not for /03's. I'd suspect that the /03 doesn't have the memory management
(nor the memory) to get Unix running.

Mark, I'll add you to the list, and bounce this there as well; someone
with more knowledge of -11 hardware should be able to set us both straight
with regards to 11/03's.
Cheers,
Warren

Warren - you're absolutely right. The 11/03 has a maximum memory
(most were not fully populated) of 56kbytes and _no_ memory
management. Any Unix (since the initial one on the PDP-7) requires
at least two memory management states: kernel and user. Much later
versions can take advantage of the 3rd mode (supervisor).
Smallest machine I ever ran Unix on was an 11/23 (the development
was done on a 11/70 because various programs were too large to run
on a non split I/D machine such as the 11/23) and it was, shall we
say, "interesting". Just enough memory (max of 248kb) to run one or
two user processes at a time (we had a rather large kernel and some
homebrew communications drivers) - you could get logged in and then
each time you typed a command the shell would get swapped out to run
your command ;).

You got it right - nothing to set straight.

Dear Michael,
Many thanks for your offer. Sorry for the delay in replying. If you are
still willing I would like to take up your offer. If you will mail me your
physical mail address, I'll send you the tape. As far as I can remember the
tape is a UNIX tar archive, that should be readable on the VMS machine and
you could give the files back to me by ftp.
(I'm taking up your offer rather than Tim Bradshaw's because you seem to
have had more recent success with reading old tapes.
Thanks again,
George

All,
Here is the latest email from SCO with regards to PDP-11 UNIX
source licenses. I'll add one comment at the bottom.
Please treat this as YOUR EYES ONLY. I haven't got permission from Dion
to forward this on (yet), but I think that more pairs of eyes than just
mine need to have a look at it for any problems.

Warren,
Good progress. We have some positive consensus developing.
Here is the proposed license terms (roughly, not fully legalized
yet). Please let me know if you see any problems with this
proposal:
Here are the terms that I think make sense:
---------------------------------------------------------------------------
License terms:
* the license covers the entire distributions (source code, binaries and
documentation) of the following versions of UNIX:
o 1st, 2nd, 3rd, 4th, 5th, 6th and 7th Edition UNIX
o 32V UNIX
o PWB/UNIX
o those portions of all 2BSD releases which are derived from UNIX
source code
* licensees have these rights wrt the binaries and source code of the above
versions of UNIX:
use
store
reproduce
edit
adapt
enchance
improve
otherwise modify
transmit electronically
repackage
* These rights are licensed to noncommercial users. The source may
not be sold nor used to develop commercial versions of UNIX.
* licensees have the right to install UNIX binaries on PDP-11 hardware and
PDP-11 emulating software
* licensees have the right to allow noncommercial use the UNIX binaries on
systems for which the product is licensed.
(Note that the latter is already permitted, given SCO's binary license
agreement for 5th, 6th and 7th Edition UNIX. We would also be happy with the
following conditions imposed in the source code and binary license for
PDP-11 UNIXes)
* license is not transferable.
* source code covered by the license cannot be distributed or disclosed
to people not covered by the license. The licensees are permitted to
collaborate on modifications and mutually share their modifications.
* SCO is not required to provide copies of any source code, binaries or
documentation with the source code and binary license for PDP-11 UNIXes
License Fee: SCO charges a one-time license fee of $100 per licensee,
for a site license for one organization.
We may, at some future time, provide source distributions (if/when
we can find the sources), but this is not committed. We know that
the licensees have, between them, most of the needed sources.
----- End of forwarded message from Dion -----
My comment. The only thing I want to change is:
* licensees have the right to install UNIX binaries on PDP-11 hardware
and PDP-11 emulating software
becomes
* licensees have the right to install UNIX software on PDP-11 hardware
and PDP-11 emulating software
This allows us to install source so as to modify it or to rebuild kernels etc.
I briefly raised the issue of source distribution (SCO or me? FTP or CD-ROM?),
but I suggested that we leave it until the licenses go on sale.
Please email your comments on this to the mailing list

I've thought of a few more changes:
In the wording from SCO, the status of `documentation' is unclear. The
following should clear this up:
+ use the term software == `source, binaries and documentation' in many
places where this is appropriate.
+ use the term `source' only where they want to restrict to licensees.
+ also, don't disclose `source' to people not covered by the SCO license
or by existing UNIX software licenses from Western Electric and AT&T.
Comments anybody?

There's 300 signatures on the petition. I'd hope that 1/2 of those
will buy licenses, and probably most would like the stuff in easy-to-use
form.
I know that Steven Schultz has access to a writer too (hint hint!).
I will probably buy another hard disk here for the PDP archive, and give
access to license holders.
I'd like to get users to suggest layout changes & what should be exploded
etc. so that we can burn a 650M CD image directly from the archive.
Currently, the archive is sitting at 250M, so there's room to explode
many of the distributions stored there.
We also need to sit down and catalogue this stuff so that it's not
just a collection of random tapes. I'm slowly doing this & have done
the most important stuff, see the Tapes/DETAILS file if you ftp in.
But more work needs to be done.
So hopefully, we can pass the archive (as a Rock Ridge image) to a few
volunteers to burn CD-R copies. Anybody in Europe who would volunteer?
Just an idea!

Kevin, until you can buy a license from SCO (soon I hope), all I can
offer are the binaries for 6th & 7th Edition. If you have an RK05 or RL02,
then you can get disk images as part of Bob Supnik's PDP-11 emulator,
at ftp://minnie.cs.adfa.oz.au/pub/PDP-11-sims/Supnik_2.3
(or a similar URL, I'm typing from memory).
If you don't have RK05 or RL02s, someone should be able to build
a suitable disk image for you. I think you'll need to go 6th Edition
as you have a /23.

Isn't ftp for a $200-programm secure enough? I'm doing beta testing
for a programm, which costs $1100 and they distribute the passwords
for ftp by unencrypted mail. They do that allready for a few releases
and I don't think they had any problems with that.

I don't think you need a very large key. Everyone, which has the
choice to crack a 512bit key or to pay $200, would choose to pay.

I think pgp is to difficult to use for some. You could use a simple
encryption programm like: ftp://isidor.ethz.ch/pub/simpl/safer.V1.1.tar.Z
which should be very portable. The passphrase could be distributed on
the license.

Dear PDP-11 UNIXers,
Just got this back from George Coulouris in the UK. He's got an
old tape with PDP-11 UNIX software on it which he'd like to read:

No, I'm afraid not.
I have been told that there is a 9-track tape drive at another centre in
London, but I haven't pursued it 'cos I was waiting for contact from your
people.

We have a TU81+ 9 track tape connected to a VMS Alpha here. So, if you send
