I don't remember any special many-programs-in-one binary like busybox in any Unix from the days when Unix was simple enough for me to understand. That covers the entire lifetime of the Research systems, but also System V and the BSDs and their sundry offspring up into at least the 1990s. I'm pretty sure OpenBSD at least still has nothing like busybox. The nearest thing was to make sure certain programs were linked statically (or existed in alternate statically- linked versions) so they would work before shared libraries were available. (It seems to be common wisdom that `sbin' means `system bin' these days, but I remember once, long ago, being told it stood for `static bin'.) Perhaps the question to ask is why such a magic program is needed at all. Is it just because programs like the shell have become so large and unwieldy that they won't fit in a small environment suitable for loading into an initramfs? Older UNIXes, even on the VAX, didn't use an initramfs. the boot code had just enough understanding of devices and file systems to load the kernel and to point it at the real root file system. The VAX hardware designers had a clever scheme on many (but, strangely, not all) VAX variants by which the hardware had several little boot ROMs, each containing a bare-bones read-only device driver for a particular device along with a few instructions to read the first sector into memory and start it, with pointers to the boot-rom driver and device ID in specified registers. That was enough to support a device-independent Unix boot block that could read unix (or another file name typed on the console) from the root of the file system at the start of the disk. I know it was because I wrote such a boot block, though I don't know whether anyone else did. (Other systems, I think, just used it to load /boot, a larger and more-capable program.) Maybe it was just that the boot environment was simpler in older systems, without the need to load kernel modules or support multiple locations and means of access for the root?

Current Ownership of 3B/WECo Computer IPs

by segaloco

Hello folks, I'm here today with a question that sprung off of some 3B20 research. When 1984 happened and ATTIS rose from the ashes of former Bell System computing efforts, presumably ATTIS received all IP rights from Western Electric for 3B processors, WE32000, and so on, and continued to sell related products through to the 3B2 line. Is this the case, is ATTIS the formal recipient of both computing software *and* hardware IPs after the breakup? Given that, plus subsequent market flow, "old AT&T" scooped up and paraded around in effigy by SBC, other old Bell stuff cannibalized by other RBOCs, spinoffs of stuff to Novell, then Caldera/SCO on the other side...who all wound up with the hardware IPs? The story as it "concludes" concerning UNIX is of course tied up in all the subsequent lawsuits, what with Novell and Caldera conflicts on ownership, transfer to the Open Group, so on and so forth, and SCO and progeny wind up with the Sys V "trunk." Is there a clear, current owner of these WECo hardware IPs, or have those waters grown even murkier than those of UNIX in the times after AT&T proper? Thanks everyone! - Matt G. P.S. As an aside (even though it's the more directly UNIX thing...) is anything after SVR4 developments that would've involved the same folks as were working up to that point in the USL group? Or did the transfer of System V to Novell also involve their own in house folks starting to take it over, then over to SCO, is there anything post SVR4 (4.2, 5, UnixWare stuff) that would even remotely be considered the logical next step by the same folks that engineered SVR4, or was it basically just another face in the crowd of "UNIX <xyz>" when USL wasn't involved anymore? Probably not the first time this has been asked either so to a finer point I'm basically fishing for whether anything post the initial SVR4 releases in the early 90s is generally considered "pure" in any way or if the Bell streams pretty much terminate with Research V10 and SVR4, (and IX) at the turn of the 90s.

The AWK Programming Language, 2nd Ed.: What's new?

by markus schnalke

Hoi, I just discovered that one of my favorite computer books about my best liked programming language (besides C) releases in a second edition. Does anyone know what the differences of 1st and 2nd edition are? As the original book is almost perfect, the only rework and extension direction I can think of is towards different implementations like gawk, mawk, portability and such things. Does anyone know more about it? Maybe some inside information? ;-) meillo

Unix install & "standalone" package

by Paul Ruizendaal

Recently, I was looking into the “Das U-Boot” boot loader package. Summarised with great simplification, u-boot bundles device drivers, file systems, commands and a Bourne-like shell into a standalone package. Normally it auto-runs a script that brings up a system, but when used in interactive mode it allows a great deal of poking around. It made me think of the “standalone” set of programs for installing early Unix. On 16-bit understandably each basic command has to be a separate standalone program, but after the shift to 32-bit bundling more functionality in a single binary would have become possible. How did the Unix “standalone” package evolve in the 80’s, both in the research and BSD lineages? Is there any retrospective paper about that? Or is it a case of “Use the source, Luke”?

Were any of the commercial unixes source-available?

by Joseph Holsten

I’ve been playing around trying to link the OpenSolaris launch commit to various pieces in the Unix History Repository, and it’s making me wonder if we’ll ever have a chance to see the history of the systems. I’m less concerned about HPUX, AIX and SCO’s offerings since I presume someone has copy inside these companies. But what about A/UX, Irix, Tru64? Did these ever get sold with licenses to source tapes? Are there copies we need to preserve in-camera so something can exist 120 years after creation or whenever copyright expires? -- Joseph Holsten http://josephholsten.com mailto:joseph@josephholsten.com tel:+1-360-927-7234

3bsd tape image

by Will Senn

Hi All, Is this the only bootable 3bsd distribution tape we have? http://sourceforge.net/projects/bsd42/files/Install%20tapes/3%20BSD/3bsd.ta… I don't like the idea that sourceforge is the only source, the provenance is unclear and I'm just not a big fan of how sourceforge handles downloads generally. I've found tarballs, but not tapes on TUHS. Thanks, Will

Update CSTR tarball

by arnold＠skeeve.com

Hello All. Nelson Beebe has added PDF files for all the .ps files that didn't have them, and I did a little bit more cleaning up of the CSTRs I made available late last week. The new file is at https://www.skeeve.com/combined-cstr-2.tar.gz Warren will eventually add them to the archive, at which point I will probably take down my copies. Nelson and I request of the CSTR authors who are on the TUHS list if they are willing to make source code for their CSTRs available? That would certainly help in the preservation effort. Thanks, Arnold

Re: Bell Labs CSTRs

by Nelson H. F. Beebe

Yesterday, Arnold Robbins kindly posted to this list a link to a bundle of Bell Labs Computing Science Technical Reports that he had, luckily for us, and for Unix, IX, and Plan 9 history, preserved in his personal library. There are 67 distinct report numbers in the bundle, and 79 different files. Today, I completed a merger of data from all of those reports into the BibTeX entries in the extensive bibliography at https://www.math.utah.edu/pub/tex/bib/unix.bib https://www.math.utah.edu/pub/tex/bib/unix.html Arnold's bundle has mostly PostScript files, but some also have PDF companions. I expect to make PDF versions available for all of them in the TUHS archives, but for now, the new BibTeX entries do not yet have suitable URLs for their retrieval. URLs will be retrofitted once the files are widely available in TUHS mirrors. Some of the reports had already been recorded in unix.bib; those that had not carry a value "Fri Aug 25" in the bibdate string, making them easy to find with a text editor, or with an SQL search in the companion SQLite3 database at https://www.math.utah.edu/pub/tex/bib/unix.db For example, % sqlite3 unix.db sqlite> .mode table sqlite> select label, title from bibtab where bibtimestamp like '2023.08.25%' order by number; For TUHS member convenience, here is a summary from unix.bib of the thus-far-recorded Bell Labs report numbers, their year (several are undated, and thus assigned 19xx), their page counts, and their titles, ordered by increasing report numbers, with column widths chosen to limit lines to 80 characters: sqlite> .mode table sqlite> .width -4 4 -8 51 sqlite> select
