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

The CHWiki (gunkies.org) isn't really the best place to put original documentation, but that's where I'd recommend putting meta-data. As for searching meta-data, are you speaking of something more powerful than Google? Noel PS: Speaking of old Unix documentation, I recently acquired a paper copy of the PDP-11 V6 Unix manual. Is that something I should scan? I don't know if you already have it (I know where to find sources in the archives, but I don't know where documentation scans live.)

Re: [TUHS] lowercase vs. uppercase PDP-7?

by Doug McIlroy

> The scans for v0 code are in lowercase. I assume printed on TTY 37. > But why is the early PDP-7 code in lowercase? Once you've used a device with lower case, upper case looks as offensive as a ransom note. I went through this in moving "up" from Whirlwind to IBM's 704. By 1969, we'd all had lower-case terminals in our homes for several years. So Unix was ASCII from the start. Upper-case from a TTY 33 was converted to lower. On the PDP-11, at least, there was an escape convention for upper case. I believe the lower-case convention was explained in the introduction. In particular if you logged in with an upper-case user name, the terminal driver was set to convert everything to lower. Remember, too, that 33's used yellow paper. For printing on white we had use other machines that had full ASCII support. Doug

Re: [TUHS] eqn

by Doug McIlroy

> 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
