> Didn't the BSTJ get phototypeset on your typesetter??
Not that I know of. But Charlie Brown's office did use it.
Brown, the CEO of AT&T, did not like wearing reading glasses
when he made a speech, so his speechwriters produced the
text in large type. Once they were into document preparation
they began to use our machine for other things. When I
discovered that confidential minutes of AT&T board meetings
were in our file system, I told them the facts of life
about computer security, especially at the center of the
UUCP universe, and persuaded the executive suite to get
its own machine.

the one at WH was directly connected to a vax 11/780, no paper tape either.
so that now finally explains why /dev/cat was write only, it was substituted
for a paper tape reader. it was always a curiosity that you could write
to it, yet never read it (i.e. get a status). a "cat /dev/cat" would
get you a "cat: cannot open /dev/cat" while a "cat /some/file > /dev/cat"
would succeed, but act like you used /dev/null instead
(as /some/file was not valid phototypeseter input)

Look at United States Patent 4074285
http://patentimages.storage.googleapis.com/pdfs/US4074285.pdf
Figure 1 is identical to the machine I ran at Whippany Bell Labs
in the early to mid 80s. It was about 4 1/2 feet tall
Figure 4 is the font wheel (seen as 16 in Fig 1) there were 4 distinct
sectors, each with a different font. One with Times Roman, one with
Times Roman Bold, one with Times Roman Italic and the last was the
symbol fonts (math, greek chars, left hand (\lh right hand \(rh etc. and
this one was made specifically for the Labs as it had a Bell Logo \(bs on it)
The paper was a roll of photo paper, glossy on the text side, rough on
the reverse, it was thick. It would end up going into the cassette
(20 in Fig 1) and would need to be developed. Not shown in the patent
figures was the developing and drying apparatus. At the end of
a job the exposed paper was in the cassette you'd remove
it from the typesetter and put into a device with rollers that would pull
it out and run it thru developer and fixer liquid chemicals. Exiting
that it would go into a dryer drum.
After it was completly dry, as it was still a continuous roll, you
would need to cut all the pages apart by hand (that is why there was
the cut mark macro (.CM) is -ms so you could tell where to cut)
As it came from a roll, no pages ever layed completely flat.
The checmical baths were nasty smelling and it gummed up the rollers.
You'd needed to regularly take the developer roller and gear guts into
the janitor's closet and scrub it with a toothbrush in the slop sink
under running water.
By the second half of the 80s it was replaced by QMS PostScript
laser printers.

Now I might be badly wrong, but nonetheless this strikes me as
badly revisionist history.
The motivation for sendmail.cf was the collision of multiple
namespaces (Arpanet, Bitnet, Usenet, etc.), each implemented
in varying nonstandard ways by different mail clients and servers,
resulting in messes like "IJQ3SRA%UCLAMVS.BITNET%SU-LINDY(a)SU-CSLI.ARPA",
as one of many, many examples, as observed in the famous
"The Hideous Name", Rob Pike & P.J. Weinberger, 1985
http://pdos.csail.mit.edu/~rsc/pike85hideous.pdf
The thing is, although sendmail.cf was/is itself hideous to understand
and therefore make maintenance changes to (although I have), it is
quite capable of actually handling the above kinds of messes, and
being extended to handle new messes as they turn up.
In short, it got the job done, despite its weaknesses.
I may be wrong, but it was my strong impression that, back in the
day, this could not be said of anyone else's code, BBN or otherwise.

I am reading the delivermail (later known as postbox and then sendmail)
code from 4.0BSD and from sccs history from June 1980.
Its arpa-mailer(8) manual says it just spools the letter and actual
delivery will be performed by the ARPANET mailer daemon and refers to
mailer(ARPA) manual. The arpa.c code says "is stuck away in the
outgoing arpanet mail queue for delivery by the true arpanet mailer."
Where is this true arpanet mailer? I am guessing it periodically looks
in /usr/spool/netmail/ and delivers the messages using FTP and RFC458.
Where is this mailer(ARPA) manual?
Where is the ftp server code used for the incoming mail? (Example
code mail-dm.c is provided for the ftp server to "handle the MAIL <user>
command over the command connection.")
Also where is the uucp-mailer(8) manpage referenced in delivermail(8)?

I stand well corrected!
Thanks,

Just saw this on the ClassicCMP list. Wonder if anyone could read it out... or if it's actually something that's already out there.

(For reference ... I am writing a detailed history of Berkeley Unix ...)
Does anyone have a copy of and the story about the Univ. of Toronto
license used for their tape distributions around 1977?
In an interview in Linux Magazine, Volume 1, Number 6, in November
1999, Joy said he just took a license from the University of Toronto
and modified it a little bit and started using that for his BSD.
It was a one-page license.
I have a copy of an early one page license (from AUUGN newsletter V01.3,
Feb/Mar 1979) which was used for the Pascal and Ex release, but it says
"(first) Berkeley Software Tape" on it which seems odd to number the
real first distribution. Also the copy of the license I have is for $60,
but the first distribution tapes were $50; these amounts are both
documented in various places for 2BSD and 1BSD respectively. Since maybe
the one page license says "(first)" and "$60", maybe there is a
different earlier license?
I also tried Googling for some of the terminology but didn't find any
hits.
So does anyone have a copy of the license for the Univ. of Toronto tape
distribution from the mid 1970's?
On that note, can anyone tell me about the story of the Toronto Unix
distributions? I understand in late 1978, the Univ. of Toronto Computing
Services group and some other Toronto-area installations were providing
their own Unix distributions for standardization of their commonly used
commands and were forming the "Toronto Distribution Centre" (mentioned
by Gregory Hill, see AUUGN V01.2, Dec-78 / Jan-79). But within a few
years, the UTCS was using BSD.
