Howdy,
I'm the secretary of the Atlanta Historical Computing Society, and a lurker
here on the TUHS list.
We're starting our process of looking for speakers at our upcoming VCF SE
4.0. It'll be April 2nd and 3rd 2016
in the Atlanta area. Since I've enjoyed reading and hearing about all the
UNIX history on this list,
I was wondering if anybody here might be willing to speak at our event.
It seems there is a good
deal of history that is captured in the minds of the members of this
list... which might make a number
of good presentations.
We're open on ranges of topics. We've had many different people speak...
the first editor of Byte,
the artist who did the covers of many Byte magazines, Jason Scott from
archive.org, some early SWTPC
engineers, some early Apple engineers including Daniel Kottke. We also
have members from the
various Vintage Computer groups from around the U.S. speak (and of course
some local members),
and some University Archivists who are starting to have to deal with old
media. This year we will have
Jerry Manock (the designer from Apple who established their design
group...designed cases for Mac, etc.)
as one speaker.
We love to learn about the history, esp. from the folks who lived it. I am
just slightly too young to have
been there (was born in '65) but always enjoy the talks. We can
accommodate from a 30 min talk to
an hour. We have a professional sound set up and stage. We have a
co-sponsor, the Computer
Museum of America that is being established in the area as well. We have
between 5 and 10 slots to fill.
We aren't a large group, but we do have a limited budget to assist with
travel, lodging, etc. We can handle
"nice" but not the Ritz :-)
If anybody is interested, please contact me and I can provide further
details. And if you'd be interested
but can't make this year, please still contact me, maybe we can work
something out in the future.
Thanks!
Earl Baugh
Secretary

Hi,
does someone know where "u" is defined on SYSIII or V7?
sys/user.h states:
extern struct user u;
But I wonder where it is defined? On ZEUS I have u.o but I'm
not able to correctly disassemble it. Right now I'm guessing
that it should be something like:
u module
$segmented
$abs %F600
global
_u array [%572 byte]
end u
But the resulting object (u.o.hd) does not match 100% the existing
u.o on the system (u.o.orig.hd).

I'm not sure how old cut is, but a quick look at the code gave me the
idea it could be backported to V7, as I'm fairly sure that cut wasn't
in V7.
It doesn't look like it needs a lot of stuff, just fclose, puts, do
and while loops. Even a v6 or v5 backport doesn't seem too difficult.

I can't remember 127 ever having a "paste" command. We did have "ov",
which overlaid adjacent pairs of formatted pages to make two-column
text. "Serial concatenation" would seem to be what was done by "pr"
or "cat".
"ov" figured in the flurry of demos on the day of pipes' birth.
nroff | ov | ov
made four-column output.
For that matter, what's the "old (127's) paste command" it refers to?
Every organization at AT&T had a number as well as a name.
In the early days of UNIX, the number for Computer Science
Research was 127. At some point a 1 was prepended, making
it 1127, but old-timers still used the three-digit code.
So it's a good guess that `127's paste command' means
one that came from, or had been modified in, Research.
I don't know when or where, though. I don't see a paste
command in V7. paste.c in V8 has exactly the same comment
at the top.

PWB did not create make; Stu Feldman did it in research.
PWB did make SCCS. I believe it also originated cico,
find and eval. Probably more, too, but I can't reliably
separate PWB's other contributions from USG's.

Hi,
i have an old Z8001 based SysIII variant and I would love to have
TCP/IP on it (SLIP first, later with a homebrew ethernet device).
I wonder if someone ever saw TCP/IP available on a System III?
I have lets say 90% of the kernel running on it as source
available and I started digging in the available 4.2 BSD sources.
It looks like there would be much to do to hack in TCP/IP on my
own (no IPC, no Net, no PTY, no....).
I got K5JB running (userland TCP/IP implementation) after I fixed
some C code because the C Compiler available on the system is.....
kinda limited.
telnetd is of course not working as there are no pseudo-teletypes
on this SYSIII. At least I got ping, echoping and ftpd up and
running via SLIP
(10.1.1.2 is my SysIII box:)

So I wonder if someone got anything SYSIII -> Net/TCP/IP related
which could help me in any way to get a SYSIII kernel capable of
TCP/IP and PTYs to get a telnetd up and running via SLIP is my
first goal.

Oliver
I just got on this list today, and I see that Larry McVoy asks:
"I wish Marc was on this list, be fun to chat."
I'd be happy to chime in on SCCS or early PWB questions, to the extent I
remember anything.
I did see a thread about PWB contributions in which people are trying to
sort out what came from research and what from the PWB group (under Evan
Ivie). As I recall, PWB was always based on research. Dick Haight would
install the latest research system from time-to-time, and then the
so-called "PWB UNIX" was whatever he had taken from research plus stuff we
were developing, such as SCCS. Unlike, say, Columbus UNIX, our kernel
always matched research at the system call level, so there never was such a
thing as a PWB-kernel dependency.
(I think the USG system was run quite differently: They had their own
system, and would merge improvements from research into it. I could be
wrong about this, as I never worked in the USG group.)

Anyone have some sun4c or hp300 gear they'd be persuaded to part with? Preferred in the SF Bay Area? It's getting a bit too difficult using broken emulators and broken cross compilers...
