A quick update. I have spl*() code as well as ia32 paging up in a small test kernel. More testing remains to be done before integrating into 32I kernel. Interrupt structure working well, as well as system call interface. Still need copyin(), copyout(), fubyte(), fuibyte(), fuword(), etc., as well as save(), resume(), etc. Future progress will slow down a little. I have accepted an adjunct teaching position, and will need to devote some otherwise free time to preparing lessons. I still expect to have a preliminary running kernel by New Years.

[pups] Possible Trix source tape Was Fwd: Re: [TUHS] Re: AI LabLispmachine source code

by Wesley Parish

First, an explanation - I'm interested in exhuming the Trix kernel - written at MIT -, which for a while was to have been the GNU kernel, according to RMS and the official FSF histories: http://en2.wikipedia.org/wiki/GNU I've been in contact with RMS - pestering the poor hacker ;) - and he's told me he's got a tape that might have the Trix source on it, but he doesn't have a tape drive or enough time. I'm in NZ, which is a bit of a long way away from Mass., so I'm asking if anyone else in the vicinity is interested in seeing one of the earlier 7th Ed. clones to be written? I've got a number of reasons for wanting to read it - among them, the wish to compare with Minix 0.0 -, putting the ubiquity of Unix during the early 80s into perspective, and of course getting something to generalize any code I write for 32VI. So, if anyone's interested and in the vicinity, just get in touch with RMS and let him know you're interested and have the time. Thanks Wesley Parish P.S. It's interesting to consider what might've been if the GNU project hadn't got behind on the Hurd, and got up-to-speed with Trix. Jokes like "Who says you can't teach an old dog GNU TRIX?" spring immediately to mind ... ----- Forwarded message from Richard Stallman <rms(a)gnu.org> ----- Date: Mon, 01 Dec 2003 23:17:32 -0500 From: Richard Stallman <rms(a)gnu.org> Reply-To: "rms(a)gnu.org" <rms(a)gnu.org> Subject: Re: [TUHS] Re: AI Lab Lispmachine source code To: Wesley Parish <wes.parish(a)paradise.net.nz> In this context it means, getting someone in the appropriate community who's interested, around to check up on the tape.

RE: [pups] Mini UNIX (V6) and V7 tapes found

All, I wrote: > Looks liek I ran into a bunchof really old and useful tapes > here.

Well, the V7 tape is saved... took a bunch of retries, but I managed to grab all of it. The V6 (Mini-UNIX) tape was OK, but some !$%(!@#$%@# must have run out of blank tapes, and decided to use this one.. it contains binary data. Major bummer, sorry :( Still working on the 2.8BSD tape, which needs more work. I also have to work on Christian Corti's tapes.. now that I have a working 800bpi SCSI drive, I actually *can* :) [thanks Walter!] Images will be sent off to the PUPS archive. Cheers, Fred

UNIX v7 projects

by Hellwig.Geisse＠mni.fh-giessen.de

Hi all, I thought that you possibly could be interested in two projects, a small one that I did over a year ago and a more recent one, which is currently under active development. In order to become acquainted with the old UNIX sources as well as the behaviour of such a system running on old (but simulated) hardware I figured out how to feed Keith Bostic's original v7 tape images into Robert M. Supnik's PDP-11 simulator so that the original bootstrap procedure (described in "Setting Up Unix - Seventh Edition") could be carried out exactly as written. In addition to that I wrote a little program which traverses the root directory of the simulated disk and extracts its contents recursively (creating the same structure and files in the host's file system). I copied all the needed software and a HOWTO into a distribution package which can be found at http://telexx.mni.fh-giessen.de/PDP11-UNIX I did this little project as a "warm-up" for another and quite a bit bigger project: porting UNIX Seventh Edition to a modern RISC-like microprocessor (named ECO32). This processor and a few peripherals are simulated for now, but we intend to transform it into real hardware (we are thinking of an FPGA implementation). These of course are dreams of the future; what we have already is this: - an ECO32 simulator - an ECO32 back-end for the LCC compiler - an ECO32 assembler/linker/loader - a UNIX 7th Edition kernel ported to ECO32 We are working on a port of many of the commands; the standard library and the shell are ready and waiting to be integrated. The homepage of this project is http://telexx.mni.fh-giessen.de/ECO32 You are welcome to download the project in its current state; don't expect anything user friendly though ;-) If you have any questions regarding these two projects, feel free to ask. - Hellwig

[pups] Re: AI Lab Lispmachine source code

by Wesley Parish

In that case, do you have any objections to me siccing the TUHS(The Unix Heritage Soc.)http://www.tuhs.org/ /PUPS(PDP11 Unix Preservation Soc.)http://minnie.tuhs.org/PUPS/ people on to it? It is something that interests us, and there'll be at least one list member within driving range of Cambridge, Mass., with plenty of time to examine the tape. I'll cc' this ove to those lists and let anyone who's interested, get in touch with you. Thanks heaps.

Re: [pups] Mini UNIX (V6) and V7 tapes found

by Jay Jaeger

FYI, the archives should already have Mini-Unix 6th Edition. (I provided the "rescue" copy). As far as I know, it was an unaltered original, so you ought to be able to compare yours with that one.

[pups] Mini UNIX (V6) and V7 tapes found

by Fred N. van Kempen

Hi all, Looks liek I ran into a bunchof really old and useful tapes here. Two tapes come from Bell Labs, and seem to contain the official Mini UNIX (Sixth Edition) and the official UNIX, Seventh Edition. Dennis (dmr): can you verify that Bell wrote these on magtapes from Graham Magnetics, with blue inside label? All the stickers and such seem "real". The V7 tape is dated 10/15/79, the V7 one is from 1977. Images available on request.. still wanna know if these are real ones, or locally-modified ones. Cheers, Fred

old Software Tools VOS, anyone?

by Aharon Robbins

Greetings all. Does anyone have any of the old Software Tools Virtual Operating System code? I know someone who is looking for it. On a related topic, if anyone has a copy of the Georgia Tech Software Tools Subsystem for Pr1me Computers, the same person would like a copy (as would I --- I was one of the two people who did the last two releases of it). Thanks, Arnold Robbins

Re: Anybody with a copy of this paper?

by Dennis Ritchie

I see that Maziels and Coile have already offered to scan (or copy) the Bach & Buroff paper. I have it too, just haven't scanned it. The original requester should also try to find the even earlier work on Unix multiprocessing: Hawley, J. A., Meyer, W. D. (1975) MUNIX: A Multiprocessing Version of UNIX, MoS. Thesis, Naval Postgraduate School - Monterey. June. Goble, G.H. and M.H.Marsh, "A Dual Processor VAX 11/780", Purdue University Technical Report, TR-EE 81-31, Sept. 1981. This used to be at http://ghg.ecn.purdue.edu/vax/paper.html but for some reason Goble's pages have been withdrawn. Probably it's at www.archive.org, but that seems unavailable just now. Dennis
