I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:
http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html
Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
----- Forwarded message from meljmel-unix(a)yahoo.com -----
Warren,
Thanks for your help. To my amazement in one day I received
8 requests for the documents you posted on the TUHS mailing
list for me. If you think it's appropriate you can post that
everything has been claimed. I will be mailing the Unix TMs
and other papers to Robert Swierczek <rmswierczek(a)gmail.com>
who said he will scan any one-of-a-kind items and make them
available to you and TUHS. The manuals/books will be going
to someone else who very much wanted them.

All, I've locked the "Women in Computing" topic in the TUHS list
as it's not specifically Unix and liable to be contentious. Feel free
to continue it over on the COFF list.
E-mail me if you'd like to join the COFF list.
Cheers, Warren

Interesting. Any ideas/thoughts on what was going on, what caused that?

Unless my leg is being pulled, I sent that for pure amusement.
Gcc has a very open mind on the subject, using both options
in the same sentence.

My impression was Doug was passing on a warning about the continued used
of mktemp(3) rather than the continued use of ASCII.

Can people _please_ pick either one list _or_ the other to reply to, so those
on both will stop getting two copies of every message? My mailbox is exploding!

I'm not sure this part is accurate: the two efforts were contemporaneous; and
my impression was they were trying to design the next step in networking, based
on _their own_ analysis of what was needed.

This is I think true, but then again, TCP/IP fell into some of those holes
too: fragmentation for one (although the issue there was unforseen problems in
doing it, not so much in it not being a real issue), all the 'unused' fields
in the IP and TCP headers for things that never got really got
used/implemented (Type of Service, Urgent, etc).

Ah, sorry, I misunderstood your point.
Anyway, this is getting a little far afield for TUHS, so at some point it
would be better to move to the 'internet-history' list if you want to explore
it in depth. But a few more...

I assume you mean 'systems running TCP/IP'? If so, I really don't know,
because for a while during that approximate period one saw many internets
which weren't connected to the Internet. (Which is why the capitalization is
important, the ill-educated morons at the AP, etc notwithstanding.) I have no
good overall sense of that community, just anecdotal (plural is not 'data').
For the ones which _were_ connected to the Internet, then prior to the advent
of the DNS, inspection of the host table file(s) would give a census. After that,
I'm not sure - I seem to recall someone did some work on a census of Internet
machines, but I forget who/were.
If you meant 'systems in general' or 'systems with networking of some sort', alas
I have even less of an idea! :-)
