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.)

Was 5ESS built on UNIX?

by Nemo

I have looked at the papers published in the AT&T Technical J. in 1985 and found no mention of UNIX. N.

Not Unix-Like. http://www.opengroup.org/openbrand/register/apple.htm It has been so since 10.0. Since 10.5 (Leopard) it has been so noted on the above Open Group page. The Open Group only lists the most recent release however. The Tech Brief for 10.7 (http://images.apple.com/media/us/osx/2012/docs/OSX_for_UNIX_Users_TB_July20…) also notes the compliance. David

Un-released/internal/special UNIX versions/ports during the years?

by Arno Griffioen

Hi! Some of the stories on here reminded me of the fact that there's also likely a whole boat-load of UNIX ports/variants in the past that were never released to customers or outside certain companies. Not talking about UNIX versions that have become obsolete or which have vanished by now like IRIX or the original Apple A/UX (now *that* was an interesting oddball though..) and such, but the ones that either died or failed or got cancelled during the product development process or were never intended to be released to the outside ar all. Personally I came across one during some UNIX consultancy work at Commodore during the time that they were working on bringing out an SVR4 release for the Amiga (which they actually sold for some time) Side-note.. Interestingly enough according to my contacts at that time inside CBM it was based on the much cheaper to license 3B2 SVR4 codebase and not the M68k codebase which explained some of the oddities and lack of M68k ABI compliance of the Amiga SVR4 release.. However.. It turned out that they had been running an SVRIII port on much older Amiga 2000's with 68020 cards for some of their internal corporate networking and email, UUCP, etc. and was called 'AMIX' internally. But as far as I know it was never released to the public or external customers. It was a fairly 'plain jane' SVRIII port with little specific 'Amiga' hardware bits supported but otherwise quite complete and pretty stable. Worked quite well in the 4MB DRAM available on these cards. The later SVR4 didn't fare so well.. Paged itself to death unless you had 8 or even (gasp!) 16MB. It was known 'outside' that something like this existed as the boot ROM's on the 68020 card had an 'AMIX' option but outside CBM few people really knew much about it. It may have been used at the University of Lowell as they developed a TI34010 based card that may already have had some support in this release. Still.. This does make me wonder.. Does anyone else know of these kinds of special 'snowflake' UNIX versions that never got out at various companies/insitutes? (and can talk about it without violating a whole stack of NDA's ;) ) No special reason.. Just idle curiosity :) Likely all these are gone forever anyway as prototypes and small run production devices and related software tends to get destroyed when companies go bust or get aquired. Bye, Arno.

Re: [TUHS] Un-released/internal/special UNIX versions/ports during the years?

by jnc＠mercury.lcs.mit.edu

> From: Dave Horsfall > Another acronym is Esc Meta Alt Ctl Shift... Good one! And there was a pretty funny fake Exxx error code - I think it was "EMACS - Editor too big"? I was never happy with the size of EMACS, and it had nothing to do with the amount of memory resources used. That big a binary implies a very large amount of source, and the more lines of code, the more places for bugs... And it makes it harder to understand, for someone working on it (to make a change/improvement). Noel

Re: [TUHS] Was 5ESS built on UNIX?

by Doug McIlroy

As Corey said, administrative computers in switching centers ran Unix, but the call-processing machines ran an unrelated operating system. The Unix lab did influence that operating system. Bob Morris instigated, and Joe Condon, Lee McMahon, Ken Thompson and others built TPC (the phone company), a switching system controlled by a PDP-11. This system actually ran the phones in CS Research for several years. ESS5 adopted some of TPC's architecture, though none of its code. Doug
