> does anyone have some eqn input and output that they can share? I have a quite elaborate document that uses eqn, pic, and tbl. In fact one table contains both pic and eqn entries (but not subtables; Latex beats roff in being recursive). Take a look at www.cs.dartmouth.edu/~doug/wallpaper.pdf. If you think you'd like to see the source, just holler. > he maybe should do Latex Sadly, math journals often demand Latex, but I've also run into journals that require Word. I wanted to submit the document above to a cartography journal until I found out they were in the Word camp. I was, however, able to convert it to Latex. At one point the American Instutute of Physics took only roff (and retypeset other manuscripts--in roff). I don't know what their practice is q now. > Maybe v0 didn't have any manuals? > I understand they weren't in roff anyways. No manuals, true. But if there had been they would have been in some version of roff, just as all Research Unix manuals were. Doug

lowercase vs. uppercase PDP-7? (was Re: Recovered /etc/passwd files)

by reed＠reedmedia.net

On Fri, 4 Oct 2019, Ken Thompson via TUHS wrote: > no, it was tty model 33. Changing the topic slightly ... The scans for v0 code are in lowercase. I assume printed on TTY 37. But why is the early PDP-7 code in lowercase? I do see the B language code for "lcase" which converts to lowercase. Maybe something like that was used? (I think I saw a scan mistake showing a "B" which is probably an "8" due to that. See pdp7-unix/src/cmd/bc.s "dab B i".) I didn't see anything in historical login code or manuals about upper versus lowercase. Any experiences about upper versus lower case to share? When did stuff get rewritten to have both cases in code? Jeremy C. Reed echo Ohl zl obbx uggc://errqzrqvn.arg/obbxf/csfrafr/ | \ tr "Onoqrsuvxzabcefghl" "Babdefhikmnoprstuy"

v0 manpages of November 3, 1970? and earliest writing about Unix?

by reed＠reedmedia.net

Several v0 manpages say 11/3/70 See https://github.com/DoctorWkt/pdp7-unix/commit/14a2a9b10bd4f9c56217234afb321… The commit message says "I've borrowed the V1 manuals from http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/man/man1 and changed them to reflect the PDP-7 utilities." Where did that 1970 date come from? Was it just made up? (Notice it is one year earlier, same day.) Maybe v0 didn't have any manuals? This was just an exercise in learning PDP7-Unix better? I understand they weren't in roff anyways. Also ... what is the earliest known date where we have some scanned/printed document? https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/ says "runs on the PDP-7 and -9 computers; a more modern version, a few months old, uses the PDP-11." but no specific date. The earliest date I see is from the 1stEdman / Dennis_v1 docs of November 3, 1971. That is a full set of docs. There must be something prior to that date. Anyone know of some early printed memo or other correspondence that mentions the work? Thanks, Jeremy C. Reed echo 'EhZ[h ^jjf0%%h[[Zc[Z_W$d[j%Xeeai%ZW[ced#]dk#f[d]k_d%' | \ tr '#-~' '\-.-{'

OT: compiler back-end bug

by Warren Toomey

All, very off-topic for TUHS but you have a bounty of experience. If any of you have Intel ia64 skills and/or fixing compiler back-end bugs, could you contact me off-list? I'm writing a back-end for the SubC compiler and I have 'one last bug'™ before it can compile itself, and I'm stuck. Details at: https://minnie.tuhs.org/wktcloud/index.php/s/QdKZAqcBytoFBkQ/download?path=… Thanks, Warren

DG/UX details?

by Chris Hanson

I’ve seen it said a couple of places that the DG/UX kernel was an almost complete rewrite and rather well-done. Have any details been preserved? There’s not a whole lot out there that I’ve been able to find about DG/UX or the AViiON workstation series (whether 88K or Intel x86). -- Chris PS - I’ve found that my asking around has prompted some people to put things online, so may as well keep asking in various places. :)

SystemV R3.2 manpages in e-form ?

by Alexander Voropay

Hi! Is there a SystemV R3.2 manpages in the "-man" macropackage form or similar ? AFAIK there are scanned documentations at bitsavers: http://bitsavers.trailing-edge.com/pdf/att/unix/System_V_386_Release_3.2/ http://bitsavers.trailing-edge.com/pdf/att/unix/System_V_Release_3/ P.S. The disks in the old days were small and vendors distributed manpages in print form... -- -=AV=-

Leaked patches... v6 to v6.5

by Warner Losh

Ok. I know there was never a v6.5... officially. But there are several references to that in different bits of the early user group news letters. This refers to v6 plus all the patches that "leaked" out of bell Labs via udel and Lou Katz. My question is, have they survived? The story sure has, but I didn't find them in the archive..

Re: [TUHS] understand earliest hardware?

by jnc＠mercury.lcs.mit.edu

> From: Jeremy C. Reed > "PDP-11 that had PDP-10 memory management, KS-1." ... What is this > PDP-11 and KS-1? Maybe this is the PDP-11/20 with KS-11? Yes. The reference to "PDP-10 memory management" is because apparently the KS11 did what the PDP-10 MMU did, i.e. divide the address space into two sections. (On the -10, one was for code, and one for data.) Alas, next to nothing is known of the KS11, although I've looked. There's a mention of it in "Odd Comments and Strange Doings in Unix": https://www.bell-labs.com/usr/dmr/www/odd.html but it doesn't say much. Noel

understand earliest hardware?

by reed＠reedmedia.net

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.
