I read in the PDP-7 reference manual that Precision CRT Display Type 30 and Precision Incremental Display Type 340 are the typical displays used with the PDP-7, but aren't standard equipment. I read about the Graphics-II scope. Was it the only display? I read it was used as a second terminal and that it would pause per display full with a button to continue. I assume this second terminal's keyboard was TTY model 33 or similar since it was the standard equipment. Does anyone know? Do you know if the PDP-7 or early edition Unixes have pen support for that Graphics-II or similar displays? Clem has written that the PDP-7 had a disk from a PDP-9. Where is this cited? The ~1971 draft "The UNIX Time-Sharing System" says first version runs on PDP-9 also. https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/ But I cannot find any other reference of running on PDP-9 at all. Was this academic? That draft calls the PDP-7 version the "first edition" but later the PDP-11/20 is called the "first edition". When did the naming of first edition get defined to not include the PDP-7 version? Or is it because the early "0th" version was never released/shared outside? Thompson interview https://www.tuhs.org/Archive/Documentation/OralHistory/transcripts/thompson… mentions an "interim machine" and a "PDP-11 that had PDP-10 memory management, KS-1." What is this interim machine? Is this a PDP-11 without a disk (for a few months?) What is this PDP-11 and KS-1? Maybe this is the PDP-11/20 with KS-11? Do we know what hardware was supported for the early editions? We don't have all the kernel code and from a quick look from what is available I didn't see specific hardware references. The later ~1974 "The UNIX Time-Sharing System" paper does mention some hardware at that time on the PDP-11/45 like a 201 dataset interface and a Tektronix 611 storage-tube display on a satellite PDP-11/20. When did a CRT with keyboard terminal like DEC vt01 (with Tektronix 611 CRT display), LS ADM-3, Hazeltine 2000, VT01A display with keyboard (what keyboard?) get supported? Any code to help find this? (The https://www.bell-labs.com/usr/dmr/www/picture.html does mention the VT01A plys keyboard). Thanks, Jeremy C.

Peter Collinson interviews?

by reed＠reedmedia.net

Does anyone know where I can find the Unix-related interviews with Dr. Peter Collinson? These are acknowledged in front-matter of Peter Salus's Quarter Century book which says previously appeared in ".EXE". Bottom of https://www.hillside.co.uk/articles/index.html mentions the magazines aren't found. I didn't try contacting him yet. I have read the Mahoney collection (archived at TUHS). Any other interview collections from long ago? Jeremy C. Reed echo Ohl zl obbx uggc://errqzrqvn.arg/obbxf/csfrafr/ | \ tr "Onoqrsuvxzabcefghl" "Babdefhikmnoprstuy"

capturing history of bs(1) command / programming language

by Dave Plonka

Hi TUHS folks, Earlier this month I did a fair bit of research on a little known Unix programming language - bs - and updated the wikipedia pages accordingly. https://en.wikipedia.org/wiki/Bs_(programming_language) Thanks for solving some bs mysteries goes to its author, Dick Haight, as well as those that got us in touch: Doug McIlroy, Brian Kernighan, and John Mashey. Apart from what is in the aforementioned wikipedia page, in exchanging email with me, Dick shared: q( I wrote bs at the time Unix (V 3?) and all of the commands were being converted from assembler to C. So Thompson’s bas became my bs — sort of. I included snobol’s succeed/fail feature (? Operator/fail return). [...] No one asked me to write bs. [...] I tried to get Dennis Ritche to add something like “? / fail” to C but he didn’t. This is probably part of why I wrote bs. I wasn’t part of the Unix inner circle (BTL Computing Research, e.g., Thompson, Ritchie, McIlroy, etc). Neither were Mashey & Dolotta. We were “support”. ) The Release 3.0 manual (1980) mentions bs prominently on page 9: Writing a program. To enter the text of a source program into a UNIX file, use ed(1). The four principal languages available under UNIX are C (see cc(1)), Fortran (see f77(1)), bs (a compiler/interpreter in the spirit of Basic, see bs(1)), and assembly language (see as(1)). Personally, some reasons I find bs noteworthy is (a) it is not much like BASIC (from today's perspective) and (b) as mentioned in the wikipedia page, "The bs language is a hybrid interpreter and compiler and [an early] divergence in Unix programming" (from Research Unix mentioning only the other three languages): q( The bs language was meant for convenient development and debugging of small, modular programs. It has a collection of syntax and features from prior, popular languages but it is internally compiled, unlike a Shell script. As such, in purpose, design, and function, bs is a largely unknown, modest predecessor of hybrid interpreted/compiled languages such as Perl and Python. ) It survives today in some System III-derived or System V-derived commercial operating systems, including HP-UX and AIX. If you have additional information that might be useful for the wikipedia page, please do share it. Peace, Dave P.S.

Re: [TUHS] Poll: good location for Unix documentation?

by jnc＠mercury.lcs.mit.edu

> From: "Brian L. Stuart" > (The tmg doc was one I remember not being there.) Err, TMG(VI) is 1/2 page long. Is that really what you were looking for? (I _did_ specify the 'UPM'.) I do happen to have the V6-era TMG _manual_, if that's what you're looking for. Noel

Poll: good location for Unix documentation?

by Warren Toomey

All, I'm just musing where is the best place to store Unix documentation. My Unix Archive is really just a filesystem, so it's not so good to capture and search metadata. Is anybody using archive.org, gunkies or something else, and have recommendations? Cheers, Warren

UNIX NEWS, volumes 1-7 out there?

by Warner Losh

I'm looking for complete compies of UNIX NEWS volumes 1-7. 8 and newer are available on the USENIX site, or on archive.org, but older ones are not. A few excerpts are published in newer login issues, but nothing complete. Reading the AUUGN issues, especially the early ones, are quite enlightening and help one judge the relative merits of later accounts with better contemporary context. I was hoping to get the same from UNIX NEWS (later login) and any other news letters that may exist from the time (I think I spotted references to one from the UK in AUUGN). It's really quite enlightening. Warner

Recovered!!! The Georgia Tech Software Tools Subystem for Prime Computers

by Arnold Robbins

Hello All. Believed lost in the mists of time for over 30 years, the Georgia Tech Software Tools Subsystem for Prime Computers, along with the Georgia Tech C Compiler for Prime Computers, have been recovered! The source code and documentation (and binary files) are available in a Github repo: https://github.com/arnoldrobbins/gt-swt. The README.md there provides some brief history and credits with respect to the recovery, and w.r.t. the subsystem and C compilers themselves. Credit to Scott Lee for making and keeping the tapes and driving the recovery process, and to Dennis Boone and yours truly for contributing financially. I set up the repo. For anyone who used and/or contributed to this software, we hope you'll enjoy this trip down memory lane. Feel free to forward this note to interested parties. Enjoy, Arnold Robbins (On behalf of the swt recovery team. :-)

congratulations to Warner on a great talk

by Eric Allman

Warner's talk just finished --- it was excellent. Those of you who didn't see it live might well want to see the recording when it comes out. eric
