Peter H. Salus comments on introduction of VAX

by Kenneth Stailey

Admittedly the page is a rant from 1997 but it does have a few tidbits. Page is here: http://www.mids.org/pay/mn/704/bits.html Excerpt about VAX: << And it's over 20 years since Gordon Bell came up with his ideas for a DEC family with a 32-bit architecture. That was implemented by Bill Demmer, Larry Portner, and Bill Strecker as DEC's VAX line: Virtual Address Extension. Bell's notion allowed DEC to produce a line of computers that continues today, and certainly occupied a number of desktops over 15 years ago. When the VAX was ``pre-announced,'' the Unix architects at Bell Labs had become disillusioned with DEC, they didn't like VMS and they thought that the VAX had an ``offensively fat instruction set.'' Anyway, Steve Johnson and Dennis Ritchie were working on their Unix port to the Interdata. (Which Steve referred to as the ``Intersnail.'') So DEC approached Charlie Roberts at AT&T in Holmdel, NJ. Tom London, John Reiser and Ken Swanson were interested; they got a VAX in early 1978. In three months they ported Version 7 to the VAX. Roberts told me: ``We got the machine in January, they had it running in April, and by August it really worked.'' >> __________________________________ Do you Yahoo!? The New Yahoo!

Epiphany?

by Wesley Parish

I downloaded 32V after thinking and thinking and thinking about it, and of course untarred and defeathered it, then had a look at some of the source code. I got a buzz out of reading it! (I usually don't give myself time to read source code, so I suppose I get out of the habit of thinking of it as a pleasure. And University tends to make one think of it as a chore ;^) Just thought I'd pass that on - and thanks to everybody - AT&T, UOC@Berkeley, SCO, Caldera and PUPS/TUHS for allowing me my unexpected pleasures! Much appreciated! Wesley Parish -- Mau e ki, "He aha te mea nui?" You ask, "What is the most important thing?" Maku e ki, "He tangata, he tangata, he tangata."

It should print the unlabeled diagnostic, but then proceed rather than fail. I just double-checked the standalone driver source, and it does provide a default label for RA82, as long as the MSCP controller actually returns RA82 as the MSCP disk ID. Does it give you an error message about disk type (some hex humber) not supported?

Well, obviously this doesn't happen on real HW, since on real HW it works (I'm typing this message on a MicroVAX 3+ running 4.3BSD-Quasijarus). But I will grant the possibility that the kernel is not w/o fault either in that perhaps it's going south (dereferencing a garbage pointer and crashing) when the MSCP controller (in this case SIMH's poor emulation) is doing something it doesn't expect. If this is so, it should be fixed, since even w/o emulators (which I refuse to support on principle) real HW can be broken and return garbage on reg reads, and the kernel must handle it gracefully. I'll look into it. MS

Hello (again) from Gregg C Levine The RPM file provided didn't build correctly. Remember I did say that I use Slackware. I don't have a running instance of Red Hat here. However, I was able to build a copy of SIMH straight from the current source code. One thing does get to me, though. This creation moves a lot slower on SIMH/VAX, then NetBSD, which worked well enough. I'm guessing that this is indeed a populated pack you have here, but do you have any idea as to why it's practically moving slower then a tortoise? This is running on a Pentium 100. As to your question, yes they are working on it, moving through the 2.4.2x series of kernels. It isn't pretty, but it is working. If you want to join the list to offer complements, or comments, or just lurk, go to their website, and tell the list-manager that I sent you.

Re: 4.3 BSD version in the Unix Archive

by Joseph F. Young

From my experience, you need to have a recent release of SIMH in order to run 4.3BSD. A few months ago, I managed to build "working" Quasijarus and Reno disk images (Quasijarus appears to work fine for me, but Reno is as buggy as I remember it being on real hardware). I had to use Ultrix and Netbsd to do the bootstrap/install; I could not get the tape boot to work at all.

Standalone format is what is known as low-level format in the PeeCee world (magnetic level stuff, certainly not needed on an emulator), and it has absolutely nothing to do with disk labeling. 4.3BSD-Quasijarus0[a] does not have standalone disklabel, but RA82 is known to the compiled-in tables and thus will work unlabeled. Also Ultrix' disk labels are not useful for 4.3BSD-Tahoe/Quasijarus, since the labels are stored in a different place in a different format. (Berkeley and DEC developed pack labels independently. BSD stores them in the boot block, Ultrix stores them in the root fs superblock, which has the disadvantage of requiring you to create some dummy root fs before you can write a label, even if you want a root fs of different size.) > Am I correct that Quasijarus supports RA82 disks (using the ra type) and the > TK50 tape (as a tms)?

Any unix for MicroPDP-11?

Greetings all, and forgive me if this was answered prevously, but i didnt see it when i grepped the archive.. Are there any *nix versions in the archive that will run on a MicroPDP11 model 630QZ-AX? Currently it is running RSX-11 /w what looks like a seagate MFM/RLL type HDD. It has only dual floppy for removeable. But i might be able to get my hands on a TK50/70 and qbus adapter for it.

Yes, for political reasons I needed to make the 4.3BSD-Quasijarus compressor a version of compress, not gzip (can't have any GNU), but I wanted to have the higher compression ratio of deflation, so I created a new version of compress that supports deflation in addition to the original LZW algorith.

"4.3BSD-Tahoe Vax distribution" is an oxymoron. Berkeley released the Tahoe tape with Tahoe binaries, no VAX binaries. I was the one who compiled the Tahoe source for the VAX, and the result was 4.3BSD-Quasijarus0. OTOH, you may be referring to the fact that the Tahoe distribution in the archive is broken. Yes, it is. Unfortunately there was an unrecoverable tape read error. > > Finally, do you know of any 4.3BSD version that will install and run on > > simh?

ctcompare 1.2 is up

by Warren Toomey

Hi all, It's probably bad form to release a new version of a program 24 hours after the last version, but version 1.2 of my C comparison tool is now available at http://minnie.tuhs.org/Programs/Ctcompare. The speed has been vastly improved by using the Rabin-Karp string comparison algorithm, and thanks go to Roger Willcocks who pointed me at the algorithm. There are no other bug fixes, and I shouldn't bring out a new version for quite a while now. So if you have access to any restricted C source trees, maybe you can send me the ctf file of the tree so I can do some comparisons! Cheers, Warren

Re: [TUHS] Fwd: Helping in the battle against SCO

by norman＠nose.cs.utoronto.ca

Andru Luvisi: If SCO holds up a piece of common code and the good guys have no response, that is bad. If SCO holds up a piece of common code and the good guys already know that it actually came from BSD, and are prepared to demonstrate such, that is good. If SCO holds up a piece of common code and the good guys already know that it was contributed to Linux by SCO/Caldera themselves, and are prepared to demonstrate such, that is good. If there is infringing code, it should be taken out of Linux as quickly as possible. ====== I'll grant all those points, but if the idea is to defang SCO, the effort still seems fruitless to me. System V and Linux both contain appallingly large volumes of code. (On a list that discusses the UNIX of the 1970s, perhaps I can say that without creating undue ruckus.) The odds are that quite a lot of the code is similar. Should we really spend months and months tracking it all down and trying to declare where each line came from, or should we wait until SCO declares a specific set of cases that matter (as they must do sooner or later or abandon the court battle)? When one is faced with an enormous set of possible computations, of which only a handful are likely to be needed in the end, lazy evaluation is usually the better choice. It does seem sensible to me for the Linux community to do its best to hunt down any infringing code, and to try to assess whether there's a serious problem lurking that nobody had noticed. But that ought to be a matter of basic ethics, having nothing to do with SCO. I doubt it is likely to make much difference to the court battle anyway: SCO's claim is that the infringing code is there now, that it was put there deliberately at IBM's instigation to do harm to them, and that the harm already exists; removing it now won't change any of that. I think it's a good idea to remove any infringements that are there now, even if they are trivial ones; but let's not fool ourselves that it will pull SCO's fangs to do so. Norman Wilson Toronto ON

Lexical comparator, was Re: the battle against SCO

by norman＠nose.cs.utoronto.ca

Warren Toomey: For me it's not just a matter of defeating SCO, it's also one of sheer indignation in the face of Saganesque FUD ("billions and billions of lines of code"). I seriously want to know if there's even the tiniest possibility that SCO is right, or if they're are just Smoking Crack Often. That's fair enough. Just remember that no matter how much you scan the code, you can't beat the FUD campaign by doing so. SCO can just claim their tools are better than yours, and continue to stonewall about showing their evidence. And as I said last week, both legally and morally the onus is on SCO to provide proof of their claims: the infringement, that it was done maliciously, that it has caused them harm. The `evidence' they have shown so far makes me doubt very much that they can prove all three of those things, or possibly any but the least- significant case of the first. As I also said last week, I don't mean to discourage anyone from doing code comparisons. Intellectually it's an interesting exercise. Ethically it's the right thing to do if the Linux community thinks it's possible that licensed code got into the system. Even legally it might make some difference to have shown due diligence, though not in the matter presently before the courts. If it makes someone feel less frustrated, that's fine too. But scanning the Linux code won't provide hard proof of anything, any more than you can claim to prove there are no leaks in your roof solely by inspection. If proof is possible, it will work the other way. Norman Wilson Toronto ON

Robert Brockway: Hi. Don't want to nitpick here but many of us think it is important to get this point straight whenever we are talking about GPLed code. The kernel is licenced (as I'm sure you know). What we are of course concerned about is: a) Code which is licenced in a manner incompatible with the GPL b) Code that the copyright holder did not authorise going into the kernel. I'm sure you were just speaking in shorthand but it is subtle point that many misinterpret. Many people outside the OSS community think that "all that free code" is in the public domain, which it is most definately not. ==== Quite right. I wasn't speaking in shorthand, I was speaking in clumsy; what I should have written is `possible that code restricted by the System V license got into the system.' Licenses come in all flavours, and whether there is any license at all is not the issue here. I certainly didn't mean, for example, to imply that all licenses are evil, reptilian kitten- eaters from another planet. Norman Wilson Toronto ON

I am in contact with someone that is looking for UNICOS system sources from (1984 to April 1986). Does anyone have or know where to locate any such sources? -- Maciek (macbiesz(a)optonline.net)

Re: Fwd: Helping in the battle against SCO

by Roger Willcocks

Here's yet another version of the malloc routines: k_malloc/k_mfree in http://www.tu-chemnitz.de/informatik/osg/lehre/vorl_BS.SRC/malloc.c I wonder where these routines were 'borrowed' from? The code appears to be intermediate between 32V and SVR4, containing assertions and using mapstart/mapsize, but without spl calls. -- Roger

Re: [TUHS] Fwd: Helping in the battle against SCO

I don't see how any diffing we do will make any difference `in the battle against SCO.' If we find cases in which Linux has incorporated System V licensed code, that will certainly be meaningful; but if, as seems likely, we don't, SCO can just say their tools are better than hours. And besides, it is SCO who have brought the complaint, so both legally and ethically it's up to SCO to prove the case, not up to others to disprove it, no matter what fearsome roars SCO emit. Comparisons done by others are certainly interesting, and I don't want to discourage anyone from doing them; just don't expect it to make any difference to the lawyers. (Not that I'm one, of course.)

Ancient Mosix patches

by Sven Dehmlow

Hi, I'm searching for patches form: - "UNIX with Satellite Processors" for Unix 6th Edition - "MOS" for Unix 7th Edition - "NSMOS" for AT&T Unix system V release 2 and all other ancient Mosix Versions (yes, the Mosix project changed it's name several times). Any hints? Sven -- "Security is just a state of mind"

Fwd: Helping in the battle against SCO

by Matthew Mastracci

What about comparing SVR1/2 to 2.4.x? SCO seems to be picking on the early 2.4.x codebase. This should also pick up the SGI code comments in the malloc() function that were recently publicized, though I'm not sure which version Linus removed the code from. Matt.

Fwd: Helping in the battle against SCO

by Warren Toomey

All, This e-mail below was prompted by an interview I gave about the SCO thing for an Australian paper: http://www.theage.com.au/articles/2003/09/09/1062902037394.html ----- Forwarded message from Ulrik Petersen <emdros(a)yahoo.dk> ----- Date: Tue, 9 Sep 2003 19:44:51 +0200 (CEST) From: Ulrik Petersen <emdros(a)yahoo.dk> Subject: Helping in the battle against SCO I saw a recent article in the Sydney Morning Herald in which a Dr. Warren Toomey (presumably you?) was quoted as saying that the TUHS has several members who have access to old copies of UNIX source code. Please ask these people to try out one of the three "shredders" which can compare sourcecode from Linux with other sourcecode, and, if possible, analyze and publish the results. One of these shredders is written by Eric S. Raymond. Here is a link to an article in which he calls for action by people with access to UNIX sourcecode: http://www.eweek.com/article2/0,4149,1257617,00.asp The program itself can be found here: http://www.catb.org/~esr/comparator/ Regards, Ulrik Petersen, Denmark ----- End forwarded message ----- Anyway, I think it's a good idea, so I'd like to hear from people who have access to recent AT&T code. My GPG and PGP keys are at http://minnie.tuhs.org/warren.html and on most keyservers if you so wish to use them. Thanks, Warren

Re: SIMH compilation problems

by Rico Pajarola

>I was having some problems compiling SIMH on FreeBSD. The reason is, all >the sources have stray MS-DOS carriage returns (^M), while UNIX only >uses line-feeds (^J). This causes GCC to misread some of the code. I >suggest you convert the sources to UNIX text format. use 'unzip -a' to automatically convert text files when unpacking. >BTW, why is networking not supported on FreeBSD? Does the pcap driver >not work? on FreeBSD you can't send packets directly over bpf (at least not the same way you can on Net-/OpenBSD). I have patches to make it use libnet for sending packets. It's a bit rough, but it works. I can put them up somewhere if anyone is interested. --rp
