tangential unix question: whatever happened to NeWS?

by ron minnich

At some point I thought NeWS source was released. Is it just another Lost Source or it is out there somewhere? Do I remember right that it was a Gosling effort?

The UNIX Command Language (1976)

by Joachim

Apologies if this has already been linked here. "The UNIX Command Languageis the first-ever paper published on the Unix shell. It was written by Ken Thompson in 1976." https://github.com/susam/tucl Joachim

> From: John Cowan > Unfortunately, glob never got its own man page Errr: https://www.tuhs.org/cgi-bin/utree.pl?file=V6/usr/man/man8/glob.8 Not the most comprehensive document, but that plus the source would be complete. Noel

reviving a bit of WWB

by Doug McIlroy

I would like to revive Lorinda Cherry's "parts". Implicit in "revival" is dispelling the hundreds of warnings from gcc -Wpedantic -Wall -Wextra. Has anybody done this already? Doug

The topic of GBACA (Get Back At Corporate America), the video game for the BLIT/5620, has come up on a Facebook group. Does anyone happen to have any details about it, source code, author, screen shots, ...? Thanks, Mary Ann

I’ve also done a port of the BBN VAX stack to V6 (running on a TI990 clone), using a serial PPP interface to connect. Experimental, but may have the OP's interest: https://www.jslite.net/cgi-bin/9995/dir?ci=tip > There's also a fairly nice Internet-capable V6 (well, PWB1, actually) from MIT > which I keep meaning to upload; it includes SMTP, FTP, etc, etc. I also have > visions of porting an ARP I wrote to it, and bringing up an Ethernet driver > for the DEQNA/DELQA, but I've yet to get to any of that. I’d love to have a look at that and compare and contrast the approaches. I’m finding that BBN’s original design, with a separate kernel thread for the network stack, is elegant but difficult to tune: too much priority and it crowds out user processes, too little and the slow PPP line is not kept busy. I think I’m beginning to understand why CSRG (and later also BBN) moved to the interrupt driven structure of 4.2BSD: perhaps it was also difficult to tune for a VAX with ethernet.

Sorry, where's this archive? Somewhere in: https://www.tuhs.org/Archive/Distributions/Research/ I assume? From the description, that might be from the 'Shoppa disks'; didn't realize that was a /23 on those. > I would assume that Ethernet boards are available, but not supported on > V6. V6, as distributed, had no networking at all. There are two V6 systems with networking in TUHS: https://minnie.tuhs.org//cgi-bin/utree.pl?file=SRI-NOSC https://minnie.tuhs.org//cgi-bin/utree.pl?file=BBN-V6 The first is an 'NCP' Unix (unless unless you have an ARPANet); the second is a fairly early TCP/IP from BBN (ditto, out of the box; although one could write an Ethernet driver for it). There's also a fairly nice Internet-capable V6 (well, PWB1, actually) from MIT which I keep meaning to upload; it includes SMTP, FTP, etc, etc. I also have visions of porting an ARP I wrote to it, and bringing up an Ethernet driver for the DEQNA/DELQA, but I've yet to get to any of that. > it's hard to glean that wisdom from reading the manual. Yeah, DEC manuals went through a phase-change around about the time of the /23. Old DEC manuals are wonderful; stuffed to the gills with deep technical details. Suitable for engineers... Later, they turned into manuals for 'ordinary people' - 'plug cable C1 into plug P1'. Semi-useless; although one can often glean a few useful morsels if you trawl through the entire thing. That's why I've been doing PDP-11 pages on the CHWiki which attempt to cover a lot of technical detail, in a high technical content/size way. If you need something that's not there, let me know, and I'll get to adding it. Noel

reboot(2) system call

by Warner Losh

I've done some research for a friend about when the reboot() system call was added, and how it related to the sync, sync, sync dance. https://bsdimp.blogspot.com/2020/07/when-unix-learned-to-reboot2.html may be of interest. Please do let me know if I've gotten something wrong... Warner

[TUHS} Qed vs ed

by M Douglas McIlroy

I used Ken's qed in pre-Unix days. I understand its big departure from the original was regular expressions. Unix ed was the same, with multi-file capability dropped. Evidently the lost function was not much missed, for it it didn't come back when machines got bigger. I remember that fairly early in PDP-11 development ed gained three features: & in the rhs of substitutions plus k and t commands. (I'm not sure about &--that was 50 years ago.). With hindsight it's surprising that a "minimalist" design had m but not t, for m can be built from t but not vice versa. A cheat sheet for multics qed is at h <http://www.bitsavers.org/pdf/honeywell/multics/swenson/6906.multics-condens…> ttp:// www.bitsavers.org/pdf//honeywell/multics/swenson/6906.multics-condensed-gui…. It had two commands I don't remember: sort(!) and transform, which I assume is like y in sed. Doug
