I realize I could run 2.11BSD on it, and as long as I stay away from a networking stack, I probably won't see too many coremap overflow errors. But I think I'd really rather run V7. However, there's one thing that makes it a less than ideal environment for me. I grew up after cursor-addressable terminals were a thing, and, even if I can eventually make "ed" do what I want, it isn't much fun. I've been an Emacs user since 1988 and my muscle memory isn't going to change soon (and failing being able to find and build Gosmacs or an early GNU Emacs, yes, I can get by in vi more easily than in ed; all those years playing Nethack poorly were good for something). So...where can I find a curses implementation (and really all I need in the termcap or terminfo layer is ANSI or VTxxx) that can be coerced into building on V7 pretty easily? Also, I think folks here might enjoy reading a little personal travelogue of some early Unix systems from my perspective (which is to say, a happy user of Unix for 30+ years but hardly ever near core development (I did do the DIAG 250 block driver for the zSeries port of OpenSolaris; then IBM pushed a little too hard on the price and Sun sold itself to (ugh) Oracle instead; the world would have been more fun if IBM had bought the company like we were betting on)). That's at https://athornton.dreamwidth.org/14340.html ; that in turn references a review I did about a year ago of The Unix Hater's Handbook, at https://athornton.dreamwidth.org/14272.html .

Fair @ 2019-06-11 6:12 UTC (permalink / raw) To: Adam Thornton; +Cc: tuhs Adam, The emacs you should search for is "Montgomery emacs" written by Warren Montgomery - it ran on PDP-11's under Unix. The first Unix system I had regular access to and learned on was the UCB Cory Hall PDP-11/70 running 2.8 BSD starting in Winter 1981, but before I learned vi, I'd learned Emacs on TOPS-20 on a DECsystem-20/60 at Stanford during summer school a few years prior, so any emacs was the quick way in for me. I switched because I got tired of having one finger on the CTRL key all day long ... IIRC, it was a stripped down version as compared to what I now know is "original" Emacs written in TECO macros - no "minibuffer" and some other stuff missing, but it had enough of the "right" keybindings that someone who knew emacs already could make it go. I'm still in touch with Ken Arnold (we were contemporaries at UCB), and he might be willing to help you make termcap & termlib go on V7 Unix. As I remember that code, it's not that big. It wouldn't surprise me if the NetBSD CVS repository for that code has the original versions. As for the Unix Hater's Handbook, a long stretch of the chapter on sendmail is an E-mail I sent to the RISKS digest after an E-mail disaster I had to manage at Apple ... I remember being surprised at seeing in the published book, until I saw the footnote directly quoting the permission I gave the authors to publish it. "Oh, yeah ..."

Fair, TUHS main list [-- Attachment #1: Type: text/plain, Size: 1321 bytes --] Two more thoughts... 1.) Zimmerman EMACS (a.k.a. CCA EMACS) ran on the PDP-11 originally when Steve wrote it at MIT. It's the closest to the original ITS/PDP-10 emacs of all the originals that I knew. I'm pretty sure he converted it to Pavel's freely available terminfo implementation at some point (when he was at Masscomp), but I think the original Zimmerman code has screwed down terminal support to a couple of terminals that were used at MIT. I've lost track of Steve, but I'll see if I can find you an email by reaching out on an Alumni list. 2.) I believe the first (joy created) termcap was in 2BSD but I don't think Arnold and Horton had started to pull the curses library out of vi yet. I think termcap itself had been but Mary Ann would be more authoritative than I. Check out the 2BSD, 3BSD, and 4BSD releases and look for the earliest versions. The C compiler is pretty much the same in all cases (the only issue I can think is that by 3BSD folks at UCB had removed dmr's 7 character variable limit), but I think curses should compile without too much issue on a virgin dmr V7 compiler. ᐧ On Tue, Jun 11, 2019 at 8:20 AM <ron@ronnatalie.com> wrote: > The other early "emacs" we ran before switching to gosmacs was > JOVE--Jonathan's Own Version of Emacs. > > > > [-- Attachment #2: Type: text/html, Size: 2336 bytes --] ^ permalink raw reply [flat|nested] 10+ messages in thread

You don't need curses for vi or emacs, they have their own comparable code internally. In fact, the original 2BSD curses from Ken Arnold was basically the vi code pulled out into a separate library. Warren Montgomery's emacs was internal to Bell Labs and intended for Bell Labs versions of PDP-11 UNIX, not 2BSD, although I recall it was often ported to the Vax. I can't recall which version of UNIX they ran in the various Computer Centers in the early 1980s when this happened, but I doubt it was V7; probably PWB or UNIX/TS. It would have had the Ritchie C compiler. I can't recall if it used termcap or had the terminals hardcoded - apparently both, according to this: https://tech-insider.org/unix/research/1983/0119.html Mary Ann On 6/11/19 6:43 AM, Clem Cole wrote: > Two more thoughts... > > 1.)

I have this on the origin of Montgomery and Zimmerman Emacs: "[Montgomery's] emacs implementation was begun in 1979, after having left MIT. I made it freely available to people INSIDE of Bell Labs, and it was widely used. It was never officially "released" from Bell Labs." "Unfortunately, several copies did get out during that time, mainly due to people who left Bell Labs to return to school or gave copies to friends. When Zimmerman modified one of those copies as the original basis for CCA emacs, AT&T and CCA had a prolonged debate over it.

Masscomp (because Steve was working for us) got a license and a redistribution license. IIRC: we could redistribute the binary for free as long as CCA got Steve's changes back. Steve definitely did the terminfo/lib work for CCA Emacs at Masscomp, as I had pointed out that AT&T was moving to terminfo but was locking it up inside of the System V (AT&T 'consider it standard' stuff - much to a number of their own people telling them not too). Pavel ?? Curtis I think ?? - I've forgotten his last name - had written a new uncontaminated version at Cornell that was a functional replacement and that could read the AT&T ASCII database and compile them properly. (I don't remember if Pavel's version could take the AT&T binary versions). I had obtained Pavel's version and we were shipping that as our terminfo/lib implementation on the Masscomp boxes and were switching our code to use it, as we had not yet signed a System V license and were shipping on a System III based one. Steve started to include Pavel's library in the CCA version, which he got from me. ᐧ On Tue, Jun 11, 2019 at 1:12 PM Lars Brinkhoff <lars@nocrew.org> wrote: > Clem Cole wrote: > > 1.)

I was at Bell Labs by the time I changed termcap/termlib and the Arnold curses into "The New Curses and Terminfo", which I presented at Usenix in Boston 1982. Terminfo was "compiled", and Curses had a new algorithm to use insert/delete line/char to avoid having to redraw the whole screen. I wasn't allowed to distribute it outside AT&T. Pavel Curtis of CMU stepped up and, at my encouragement, volunteered to rewrite it to the same spec. I worked with him on the spec and the algorithm, and his version was available to open source. If you were at the Boston conference, you may recall my presentation. My Director, Tony Cuilwik, was in the audience, and this was my first public talk since joining Bell Labs, so I was nervous. As I was stepping to the podium to begin my talk, Armando Stettner interrupted to present me with the "Flying Rubber Chicken Award". Someone offstage threw him a rubber chicken. The chicken was quickly vanished and replaced with the real award, "The Term Cap". Armando explained that the hat was an Bell System hard hat, donated by Ken Thompson himself. Scotched to the hat were "hacker eyes" (googly eye glasses) and a Steve Martin style arrow-through-the-head "for the term info to go in and come out". He left me there, holding the award, as I had to reboot my brain to begin my talk. I still have that award. It graced my workplace for many years. When I worked at Bank One in Columbus, I put it on a styrofoam head on top of my cube. A coworker had contributed a yellow cheerleader pompom which gave her hair. When Chase bought Bank One, there were Chase big shots coming through our building, I was told to take it down because it didn't look "professional". I was offended - "that's an award!" It stayed down for several months, and people complained because, in that cube farm of identical rows of cubes, "people used that for navigation". I made a little plaque explaining the award and placed it next to the restored Term Cap on my cube. The award sat on my cube at SDG&E for 11 years without incident, and now that I'm retired I proudly display it on my piano at home.
