Clem Cole: > Apologies to TUHS - other than please don't think Fortran did not > impact UNIX and its peers. Fortran had an important (if indirect) influence in early Unix. From Dennis's memories of the early days of Unix on the PDP-7: Soon after TMG became available, Thompson decided that we could not pretend to offer a real computing service without Fortran, so he sat down to write a Fortran in TMG. As I recall, the intent to handle Fortran lasted about a week. What he produced instead was a definition of and a compiler for the new language B. (The Evolution of the Unix Time-Sharing System; see the 1984 UNIX System issue of the BLTJ for the whole thing, or just read https://www.bell-labs.com/usr/dmr/www/hist.html) Now let's move on to the name `rc'. Not the shell, but the usage as part of a file name. Those two characters appear at the end of the many annoying, and mostly pointless, configuration files that litter one's home directory these days, apparently copied from the old system-startup script /etc/rc as if the name means `startup commands' (or something beginning with r, I suppose, instead of startup). But I recall reading somewhere that it just stood for `runcom,' a Multics-derived term for what we now call a shell script. I can't find a citation to back up that claim, though. Anyone else remember where to look? Norman Wilson Toronto ON

Re: crt0 -- what's in that name?

by Douglas McIlroy

>I thought it was pretty well known that it [BSS] stands for, "Block Started (by) Symbol"? BSS was a "pseudo-operation" in SAP (SHARE assembly program) for the IBM 704. My recollection is that the assembler manual called it "block starting at symbol". There was also a BES (block ending at symbol) pseudo-op. Both reserved a block of memory, with the assembler assigning the appropriate value to the pseudo-op's label. The reason for BES was that index registers were subtractive. There was a loop-ending instruction ,TIX (transfer on index), that decreased the index by a specified amount and transferred to a specified location unless the index hit zero, in which case the instruction counter continued in sequence. BES was originally conceived for addressing an array stored by increasing subscript but indexed by a register that counted down. BES was also useful for FORTRAN object code, which stored arrays backward and kept the true, uncomplemented subscript in an index register. Doug

I want something tight. Quotes take precedence over all other things. What is a "troff symbol"? I can only think of troff escapes, which can only appear in quotes , so are not eqn things in their own right. (In user errors they may be seen as punctuation, etc.) Ditto for "eqn symbol"? Perhaps the union of some or all of the things that follow in the list? Ditto again for "mathematical punctuation". Comma is one example I can think of. Apostrophe, read as "prime", may be another. Are there more? Is "surrounded by" inclusive or exclusive? Why is "character" distinguished from "word"? The ??? question bears on the issue of whether sintheta is one thing or two. The word "maximal" will probably figure in the answer Another (sticky) point is how punctuation sticks to an adjacent thing. For example, eqn inserts space in (a,b), but keeps the whole thing(?) together in 2 sup (a,b). Doug

Major update in unix.bib

by Nelson H. F. Beebe

Thanks to Unix document recovery work by some TUHS list members that has been recently added to the archives at minnie.tuhs.org, a large Bell Labs bibliography about Unix has been uncovered and is now available online. I have spent time this week converting the 59-page PDF file to a somewhat searchable OCR'ed PDF, and from a text conversion of that file, to relatively clean BibTeX entries in https://www.math.utah.edu/pub/tex/bib/unix.bib [change .bib to .html for similar view with hypertext links]. The bibliography recorded in entry Scheiderman:1980:UB, with a long remark field, has 457 entries, from the years 1972 to 1980, but due to splitting into subject-specific sections, there are some duplications: 448 remain after data merger. Much work remains to be done, including locating electronic copies of those reports, correcting truncated data, and getting suitable URLs retrofitted into their BibTeX entries. However, I prefer a release-early-and-often approach to bibliographic data distribution, whence this announcement to the TUHS list and others. For searching convenience, I have created an SQLite3 portable database file at https://www.math.utah.edu/pub/tex/bib/unix.db There is a tutorial on SQL searching of BibTeX data in a paper and talk slides at BibTeX meets relational databases https://www.math.utah.edu/~beebe/talks/#2009 and further documentation about BibTeX itself at BibTeX Information and Tutorial https://www.math.utah.edu/pub/bibnet/bibtex-info.html Below are some samples of searches to find the earliest mention of selected topics in the Bell Labs technical memoranda. Even if you have never used SQL queries, they should be fairly understandable, and the new entries all carry identical bibtimestamp values to make their identification and selection easy. % sqlite3 unix.db .headers on .mode table -- Find the earliest entries select label, year, author from bibtab where (filename = 'unix.bib') and (bibtimestamp like '2023.06.06%') order by year, label limit 10; +--------------------+------+-------------------------------------+ | label | year | author | +--------------------+------+-------------------------------------+ | McIlroy:1972:MTC | 1972 | M.

Pixel 100/AP UNIX Computer

by segaloco

After talking with the folks I bought the recent documents from, they let me know they are also selling a piece of hardware: https://www.ebay.com/itm/125714380860 After the link is an auction for an Instrumentation Laboratory Pixel 100/AP. A small booklet included with the many documents I received indicates as of 1982 the Pixel 100/AP ran a System III derivative. The booklet goes on to present a summary of user commands and options. Despite the System III basis, included among these are the C shell and ex/vi. I have no room for hardware or honestly at that price point it'd be worth the preservation effort. Hopefully it finds a good home, it includes an almost complete documentation set save for the small booklet I've got (which could be separate promo material for all I know) In any case, there were a few letters amongst the documents suggesting the original owner was involved in the production of this system, particularly in the area of OS details. If I find any noteworthy information I'll pass it along. - Matt G. P.S. If anyone knows of a preservation effort accepting new machines I can pass this along.

Some AT&T Promotional Material/Pricing from Early 80s

by segaloco

Hello, I've just today received another box from the person I got that set of UNIX manual binders from and hoo boy there's some cool stuff in here. It'll probably be a bit before I scan it all, but among the many bits is a folder bearing "Software by the Bell System" on the front cover with a photo of some tape reels lying around. The back is a simple black 70's Bell system logo. Flipping to the interior, the left panel of the folder bears facsimile AT&T letterhead with a "letter" from Otis L. Wilson, Technology Licensing Manager, denoting what promotional materials are enclosed. Among the various terms of the licenses mentioned is: 'all software comes "as is" -- with no maintenance agreements or technical support' Between this and the Bell logos all over this stuff, I presume it is prior to 1982. As for the contents themselves, there are pages for V6, V7, Mini-UNIX, PWB, 32V, and System III, the last of which is a photocopy whereas all the others are on some nice glossy cardstock, so I presume this was hot out the door on the heels of System III as a commercial release. Aside from pages describing each of these UNIX versions, there is a separate page describing "The Phototypesetter Package", in other words, pre-DWB distribution of TROFF and friends. Aside from the UNIX stuff, there are also various utilities amongst IBM 360/370 and Honeywell 600/6000 systems and some various scientific and mathematical systems. Also included is "Summary of UNIX System III" which looks to be a bit of an amalgamation of info from some of the "Documents for UNIX 3.0" set distributed with System III. Unfortunately, being for external release, the document is very of the mindset of "here's what changes from V7/32V to System III" rather than that sweet sweet "here's what changes from PWB 2.0 to 3.0" that I hope to find (or create) sometime. Anywho, finally amongst the promo material was an (undated) letter from M.B. Wicker (Technology Licensing, AT&T) to an unlisted recipient, obviously just copy they sent to everyone, essentially communicating the terms of UNIX System III in more detail. Between all of these materials, the following are UNIX-related prices I could find: UNIX Sixth Edition - Initial CPU - $20,000 - Additional CPUs - $6,700 - UNIX Programmer's Manual - $30 - Documents for Use with UNIX - $30 - System III upgrade - $26,000 - System III add CPU - $10,300 PWB/UNIX - Initial CPU - $30,000 - Additional CPUs - $10,000 - PWB/UNIX User's Manual - $40 - Documents for PWB/UNIX - $40 - System III upgrade - $16,000 - System III add CPU - $7,000 Mini-UNIX - Initial CPU - $12,000 - Additional CPUs - $4,000 - UNIX Programmer's Manual - $30 - Doucments for Use with Mini-UNIX - $30 UNIX/V7 - Initial CPU - $28,000 - Additional CPUs - $9,400 - UNIX Programmer's Manual, Vol. 1 - $40 - UNIX Programmer's Manual, Vols. 2A and 2B - $60 - System III upgrade - $18,000 - System III add CPU - $7,600 UNIX/32V - Initial CPU - $40,000 - Additional CPUs - $15,000 - UNIX/32V Programmer's Manual - $40 - UNIX/32V Programmer's Manual, Vols. 2A and 2B - $60 - System III upgrade - $6,000 - System III add CPU - $2,000 UNIX System III - Initial CPU - $43,000 - Additional CPUs - $16,000 - UNIX User's Manual - $40 - Programmer's Manual for UNIX System III, Volume 2A and 2B - $40 each - The separate page detailing System III further goes on to break down that a non-refundable payment of $25,000 to sublicense object code Phototypesetter (Version 7) - Initial CPU - $3,300 - Additional CPUs - $1,100 - Documents for Use with Phototypesetter - Version Seven - $20 Additionally there are options to upgrade a V6&V7 supporting license to System III for $14,000 and add additional CPUs to those terms for $6,300. The same for a group of V7 and PWB for $4,000 and $3,000 for first CPU and addtional CPUs respectively. Of note is that all documents listed above could be purchased from the Computing Information Service in Murray Hill *except* those issued for UNIX System III, which instead were to be ordered from the Western Electric Patent Licensing Organization. This reflects the shift to WECo distribution from Bell Labs themselves, as would continue to be the case for 3B20S shipments of 4.1 and the eventual 5.0 and System V releases. In addition to the promotional materials are also "Specimen Copy" blanks of the various licenses involved in at least System III, perhaps other versions (there are blanks where LICENSED SOFTWARE is supposed to be written/typed in). Finally, in the same folder is also a nice stack of UNIX summary documents spanning different versions. There are summaries for PWB, Mini-UNIX, V7, and 32V. Additionally, there is a document "Proposal to Provide VAX UNIX system support at Berkeley" by Bob Fabry. A quick internet search didn't turn up a PDF of this, so I have to wonder if it's preserved somewhere. If not, it will be. The other document here may prove even more interesting though: "The UNIX Time-Sharing System for UNIVAC 1100 Series Systems - 7th Edition Summary", dated October 19th, 1981. Can't say I've seen this anywhere, just mention of the UNIVAC version in the BSTJ article on UNIX porting experiences. A quick perusal yields a document very similar to the V7 and 32V summaries, but with UNIVAC-isms pointed out. Anywho, there's more material in this box than just this stuff, but this floated to the top as particularly significant. Among other contents are a "UNIX System and 'C' Language" "Training from the Source" foldout from WECo's Corporate Education group, listing 16 courses available at various training centers. There is a copy (nicely produced) of the 1984 draft /usr/group standard along with a stapled, standard printer document titled "Reviewer's Guide to the PROPOSED /usr/group Standard" dated March 14, 1984. I must say, the publication quality for this being a proposed standard is quite nice, I'd expect a draft to be lucky to have staples if not being just paper-clipped together, but it has a nice printed cover with a logo and all. There is one other thing but I'm making a separate thread for that one, might warrant quite different feedback than this stuff. - Matt G.

DOD KSOS Secure UNIX Operating System Manual and Final Report

by segaloco

As promised in the other email, I had one other tidbit worth sharing some detail on but that is very different from WECo promo and informational material. What I've got here are two documents pertaining to the "Department of Defence Kernelized Secure Operating System" project as undertaken by Ford's Western Development Laboratories Division. The documents in question are https://apps.dtic.mil/sti/pdfs/ADA111577.pdf and https://apps.dtic.mil/sti/pdfs/ADA111566.pdf and represent the User's Manuals and Final Report respectively on this KSOS system. These appear to be from the same microfiche as the documents linked based on splotches on the last page's date frame, although the copies I have here have the full frame, the PDFs linked seem to have the last panel cropped to a small square in the middle. Not super significant, but sometimes it's the little details. Anywho, unfortunately I don't have much to report, I got a bit excited while looking for these at first because I was having a hard time turning up PDFs, thought I had stumbled upon something unseen for some time, but in the gulf between last email and this I found them. Silver lining is one less set of documents to scan, but nothing to really expose that isn't already a click away. - Matt G.

Re: CB-UNIX dsw(1l) Page from PDP-7?

by norman＠oclsc.org

Rather an aside, but the alt.sysadmin.recovery message referenced in https://www.tuhs.org/pipermail/tuhs/1999-November/001203.html chimes interesting chords for me. If you care only about technical stuff, you should skip to your next e-mail message now. On one hand, the doubly-embedded net.unix-wizards message from Dennis, dated 1984-12-08, containing the original dsw.s: that was posted a few months after I joined Bell Labs, and may even have been partly my fault. 1984 was the nominal 15th anniversary of UNIX; as a member of the steering committee of the recently-formed UNIX* Special Interest Group in US DECUS, I convinced Dennis to attend the Fall 1984 Symposium, in Anaheim in early December, as part of a celebration. As another part, I made copies of the V1-V7 manuals in the UNIX Room and had them shipped out so people could leaf through the history. I think Dennis dug out the PDP-7 source-code books as a contribution to that effort; I am all but certain we brought copies of those too. Of course I had the copies returned not to the Labs but to my home address. I still have them, now on a shelf in my home office. A good friend offered to take care of shipping them back to New Jersey, of course making her own copies in return. I also recall that the conference hotel happened to give me room 127. I offered to swap with Dennis, since he deserved that number more than I did (the extra digit had already been prepended before I joined) but he cheerfully declined. On the other hand--not as historic except to me--the author of the singly-embedded 1999-11-23 alt.sysadmin.recovery message is now (and has for some years been) a co-worker and a good friend. So this single 1999 TUHS posting touches points near both the beginning and the end (so far) of my career, and two different groups of smart people who are fun to work with. Norman Wilson Toronto ON

CB-UNIX dsw(1l) Page from PDP-7?

by segaloco

While performing my CB-UNIX 2.3 manual separation, among the many curious things I came across was this manual page: https://www.tuhs.org/Archive/Distributions/USDL/CB_Unix/man/man1/dsw.1l.pdf The dsw(I) pages I've seen in the various UNIX manuals are all for the interactive delete utility, but make brief mention of the history of the command being amusing. I've seen some communication on the matter of the years here, but had never come across a manual page for the former version of dsw. In the linked page up there is the actual "delete from switches" version of dsw. What I find particularly interesting is that the footer indicates this was printed 8/11/81, but likewise indicates the command is "PDP-7 local". This raises a couple of questions: - Did Columbus ever touch PDP-7 UNIX? - Did dsw(I) as "delete from switches" ever make it to PDP-11 UNIX? Even the V1 manual lists the "delete interactively" utility, not this. - If neither are true, that begs the question of where this page came from, if there was ever a formalized PDP-7 manual that it would've descended from or not, etc. Finally, this page plainly spells out the history of the command in the bugs section: "This command was written in 2 minutes to delete a particular file that managed to get an 0200 bit in its name. It should work by printing the name of each file in a specified directory and requestion a 'y' or 'n' answer. Better, it should be an option of rm(1). The name is mnemonic, but likely to cause trouble in the future." So the first bug is eventually mitigated by transforming this into the more familiar dsw. I can't say what the latter means, whether it's a concern of "dsw" colliding with some reserved word eventually or is more poking fun at the other folk etymology of "delete s__t work". In any case, I hadn't seen the etymology explained to this degree in the mailing list references I found while searching around, so figured I'd share this analysis. - Matt G. P.S. There is mention here that Dennis Ritchie shared the original dsw manpage at some point https://www.tuhs.org/pipermail/tuhs/1999-November/001203.html however the link in question appears to be dead. In any case, the source for the PDP-7 version is in that email if anyone wants to look at it, although looks to be the same as what is in the archive.
