Hi.
What's the difference between spell.old and spell in the V10 sources?
I'm guessing spell.old is the original version for the small-address-space
PDP-11 and that plain spell takes better advantage of the roomier vax...
Thanks,
Arnold

As early as V5 the (thompson) shell prompts were “#” and “%”, and “:” for
a label. As the goto command exists in V4 (there is a man page for it), I
would assume that those characters were used in V4 as well. So it would
seem to go back to 1974.
In the V7 (bourne) shell the default non-root prompt is “$”. Goto is
dropped at this point.
Don’t know when or where “>” was first used on Unix as a prompt character
(on my boxes it still is “$”).

I’d be interested in anything on Spider/Datakit networking in V4-V7.
(at them moment the trail starts at V8, with just a few hints in earlier
source materials, and the bits that Noel found).
My thinking is that there were two main lines of early networking development
on Unix (and I realise that this gross simplification excludes many other
worthy projects):
1. The “sockets” lineage from UoI NCP Unix -> BBN NCP Unix -> BBN TCP Unix
-> 4.1a BSD -> 4.2 BSD
2. The “device” lineage from Spider -> Datakit -> UUCP -> streams
-> STREAMS
In the first lineage there is much material available, in the second very
little. This is probably because Datakit was AT&T confidential at the time.

Actually, I think if you go back far enough (1930's), it was part of UCB,
back when Lawrence first started it.
And of course the DoE didn't exist until 1977, so during the early ARPANET
era if would have been under the AEC, and then I assume the Energy Research
and Development Administration after 1974 (I assume it didn't go with the NRC
when the AEC was split up).

This page:
http://www2.lbl.gov/Publications/75th/files/exhibit.html
mentions 3 links between LBL and Arpanet:
- In 1974, the Lab’s CDC 6600 became the first online supercomputer when it was connected to ARPANET, the Internet’s predecessor.
- In 1986, when the Internet was on the verge of collapse from congestion, a Berkeley Lab researcher, Van Jacobson, co-developed the congestion control algorithms that allowed the Internet to keep growing.
- In 1995, Jacobson and Steven McCanne developed MBone, the first successful software for multiparty audio and video conferencing over the Internet.
I don’t think anybody was thinking you wilfully misrepresented things,
it is always interesting to hear about strands of history that might
have been missed earlier.
It would be helpful to better understand the time period, people
involved and the scope of work.
I’m a bit confused as to what time period you are referring to: I
think you are referring to the initial development of Arpanet, i.e.
the second half of the sixties. Is that correct?
There is a page here with some info on events in that period and it
may have missed some interesting development work done at LBL:

FWIW, I was actually at many of those meetings. (You can find my name in a lot
of those Meeting Notes.) Nobody from LBL, or UCB in general, was involved -
and the Meeting Notes (which, you will note, are quite detailed) indicate the
same thing.
(Later on, of course, Van Jacobson of LBL did some imporant work on TCP
congestion control, but that was in '87 or so - I can't instantly lay my hands
on my copy of Van's famous e-mail, to get a more exact date - some years after
the full-scale deployment of TCP/IP in January, 1983.)
> Why would I misrepresent?
Perhaps you are conflating several different things in your memory? Human
memory is very fallible, which is why historians prefer contemporary documents
(and even those sometimes have errors). Here:
http://www.chiappa.net/~jnc/nontech/tmlotus.html
is a mildly amusing example (from a completely different arena) of all that.
Noel
Does anyone remember the reason that processes blocked in I/O don't catch
signals? When did that become a thing, was that part of the original
design or did that happen in BSD?
I'm asking because I'm banging on FreeBSD and I can wedge it hard, to
the point that it won't recover, by just beating on tons of memory.
