so the question of pseudo tty came up today. My memory is that it started with TOPS-10, though I doubt I know enough. Vague memory says there was a PTY: device. Further, I believe pty came in from UCB ca 1977 or so? I'm wondering if people who were Present at the Creation can fill in the gaps. Thanks

C history question: why is signed integer overflow UB?

by Dan Cross

[Note: A few folks Cc'ed directly] This is not exactly a Unix history question, but given the close relationship between C's development and that of Unix, perhaps it is both topical and someone may chime in with a definitive answer. Starting with the 1990 ANSI/ISO C standard, and continuing on to the present day, C has specified that signed integer overflow is "undefined behavior"; unsigned integer arithmetic is defined to be modular, and unsigned integer operations thus cannot meaningfully … [View More]

RFS

by Steve Simon

my memory is the major differences between the research RFS and USG’s RFS was the support of ioctls (as mentioned) and, Research RFS supported exporting file trees with an abstract name rather than the path on the source machine - a small but very useful change. research RFS could (i feel) be seen as the direct ancestor of plan9’s 9p protocol. -Steve

CSIRO Unix

by Jonathan Gray

CSIRO is an Australian government research agency with a long history. Siromath, a commercial spinoff, had a binary redistribution license for Unix. The Siromath Unix was called SIRONIX. The Australian Unison computer was sold with SIRONIX. Siromath was also going to provide a version of Unix for the DCR/CSIRONET workstation. At some point they switched to a port of System V/68 from Neology/Softway. Does anyone know why? Or if the CSIRONET workstation got beyond the prototype stage? Did … [View More]

Teletypes used for early Unix

by Thalia Archibald

Hello all, What teleprinter models were used at Bell Labs, particularly by the Unix groups? Judging by troff escape sequences, it expected a Teletype Model 37, and early all-caps support implies Model 33 usage. But I don’t have a sense of what users and the core developers used. I am working on building a Teletype Model 37 ASR emulator for my PiDP-11 with the goal of replicating the early Unix experience as accurately as possible without physical hardware. As I get deeper into research, I’ve … [View More]

off topic: StarTech.com parallel port printer server to give away

by arnold＠skeeve.com

Hi All. Cleaning up the basement, I found a parallel port printer ethernet server. It lets you put a parallel port printer onto your local network. It speaks the BSD lpr protocol. I used to use it on an HP LaserJet 6 printer. If anyone wants it for an old printer you might have laying around, please let me know, *privately*. It's yours for the cost of postage from Israel. Note, I no longer remember how I got it working with Linux, but I did... This was a llllooonnnngggg time agao. :-) Thanks, Arnold

Re: upwards from ed (was: End of an era: the last ATC)

by Steve Simon

sam was my only editor from 92 when i discovered it until last year. under continual peer pressure i moved to zed on a mac which does many clever things i don’t need and even occasionally gets in the way, but (for me) it had one killer feature: i write go these days and use dozens of third party libraries. zed allows me to ask “what methods are available on this variable?” i would love to go back to sam but i fear adding treesitter and the rest needed to support this feature would kill one … [View More]
