hal.gnu.ai.mit.edu

by Steve Mynott

Back in the early 90s before the FSF withdrew the service due to misuse it was possible to write off to them to get a free shell account on "hal" as I did. I recall having to telnet through one of three gateway systems so assume it was on its own little subnet. But I can't remember what sort of system (hardware or OS) it was now however and wondered if anyone else did? -- Steve Mynott <steve.mynott(a)gmail.com> cv25519/ECF8B611205B447E091246AF959E3D6197190DD5

Re: [TUHS] changes in C compilers

by Norman Wilson

Clem Cole: Clearly from the time, ditroff did not yet exist. The more I think about it, Brian K actually might know some of the story. === I'm quite sure Brian Kernighan knows the full story of the origins of typesetter-independent troff (as it was originally called, in CSTR 97, published in 1981; the binary was just /usr/bin/troff). The reason I'm so sure of that is that it was Brian who rewrote troff to bring it into the modern era and to make it supportable. He's also the author of the CSTR. Norman Wilson Toronto ON

I've personally done UUCP over SSH multiple times. It looks like TCP port 540 is reserved for UUCP over TCP and TCP port 4031 is reserved for UUCP over SSL. So, we'll definitely be offering those services inside of RetroNet. Currently the idea is to make services available inside of RetroNet. I don't know how many services will be openly available across the Internet. Primarily for security / safety reasons. That being said, I think we are planing on a gateway for things. We're certainly willing to talk about other options too. > I would like to see UUCP over ether as serial for backwards compatibility > to talk to old machines and emulation. I / we would like to know more about the "over ether as serial" part. I'd think the goal would be to have RS-232 (et al) serial ports that can connect to retro computers and make things look like what they would expect to see. That being said, we will either need an RS-232 (et al) serial port on a gateway, or something else to translate from serial to likely an IP~>telnet connection. If you have ideas, please bring them and share them. > Some of the kid's I know would be blown away by Cnews and television or > transported over Internet or PPP links.

C++ / Kernel

by ron＠ronnatalie.com

> Has anyone experimented with building Unix using C++, to take > advantage of strong typing? My guess is no--it would be a Herculean task likely to introduce more bugs than it would fix. I'm not sure what "strong typing" gain you expect to find. With the exception of the void* difference, C++ isn't much more "type strong" than C. A lot of the type issues you can find on the Kernel just by turning up the compiler warnings (or use lint). The biggest issue we had was BSD didn't use void* at all. Had they converted pointers to void*, which is in implementation necessarily the same as char*, C would have done the right thing. The problem is they did what I call "Conversion by union." They would store a char* into one element of a union and read it out of another typed pointer. This works fine for a VAX where all pointers are the same format, but fails on word address machines (notably in our case the HEP where the target size is encoded in the low order bits of the pointer). Still, running around and fixing those was only a few hours work. The DevSwitch is the beginnings of an object oriented philosophy. Alas, the original UNIX used it only for mapping major dev numbers to functions. It got some later use for other things like multi filesystemsupport. The scary supportability thing in the kernel, isn't so much typing, but the failuer to "hide" implementation details of one part of the kernel from the other.

Research UNIX on the AT&T 3B2?

by Norman Wilson

Seth Morabito: After the past several years of focusing on 3B2 preservation and emulation, I've begun to wonder whether 3B2 hardware was used very much inside of Bell Labs. Has anyone ever heard whether Research UNIX was ever ported to the WE32100? I've certainly never seen anything that would suggest it was, but I'd love to be proven wrong. ===== I never heard of anyone doing such a thing. Had they ported the kernel I would almost certainly have heard about it, because they'd have asked me a question or two. Much VAX-specific structure inside there that I'd love to have had the time and energy to clean up. It's possible that someone did a semi-port, moving a lot of the user-mode tools like the shell and the Jerq software. Dave Kapilow did something like that for early SunOS, including a mux-like X11 terminal program called sux, built atop a library that did a simple mapping from Jerq graphics-library calls to X11. Certainly nobody inside 1127 ever did either of those things. A few of us played with 3B1 or 3B2 systems (I remember Tom Duff had a 3B1 at home at one point), but never very seriously.

Re: [TUHS] changes in C compilers

> From: Clem Cole > Looking at the v6 distribution tape I have, the assembler versions of > roff and nroff was there Whoa! The standard V6 distribution tape, as in the one there are a couple of copies of in the repository, does not have that. Do you have that in machine-readable form? If so, can you get it to Mr. Toomey ASAP? > The order I remember is this ... V5, V6, Patches, Typesetter C, TS, V7 Where do USG and PWB fit into that? The repository has PWB (or, what is _claimed_ to be PWB), which is how I know the MIT system is PWB. But there is nothing of the others (except the kernel manual for USG, which shows that the version described in it is basically V6). If anyone has TS in _any_ form (including hardcopy listings, please speak up! Those 'early' PDP-11 versions are very poorly documented now, and I'd love to get more on them. Noel
