Hi all, would anybody have a copy of this paper: Multiprocessor UNIX operating systems. Bach, M.J., and Buroff. S.J. Bell Systems. Tech. J. 63. 8 (Oct. 1984) 1733-1749. If so, would you be able to scan it in and e-mail it to me, or even photocopy it and post it to me? I'll reimburse you for time & postage. Thanks in advance, Warren

[pups] UC08 and Ultrix-3.1

by nao

Hi, all. I finally discarded my RD54 haunted by frustrating retries and burnt my yen on an Emulex UC08 board. I installed it to my PDP-11/53 and attached an old DDS2 drive and a 230MB MO drive. Now 2.11BSD runs as smooth as silk. Next I tried to install Ultrix-3.1, but I entered an unexpected weirdness. After entering setup phase 1, the initial setup aborted saying that it failed to access files under /usr. Some lengthy investigation revealed that UC08's emulation confuses Ultrix. The MO drive pretends an RD54 and the installer is quite confident of it. Once the kernel is in service, it checks the controller board and identifies it as a KDA50, which is connected to RAxx drives. Now the kernel treat the MO disk as a RAxx. Since RD54 and RAxx have different partition layout, kernel failes to find /usr filesystem and the installation process fails. To avoid this gap, I put a 540MB drive (bigger than an RA81, which is about 469MB) and configured it to behave as an RA81. The installation process now goes. After carefully studying src/sys/conf/dksizes.c, I also used a 230MB MO disk as an undersized RA81 and it seems to work well. I also tried SIMH. This time an emulated RD54 worked well, but a tape drive suddenly stopped during installation. I traced TMSCP protocol log and found a bug in the tape driver of Ultrix standalone installer, which hitted hidden incompatibility of SIMH. Here is an ad hoc patch for SIMH: --- simh.orig/PDP11/pdp11_tq.c Mon May 19 20:24:04 2003 +++ simh/PDP11/pdp11_tq.c Thu Nov 20 18:32:43 2003 @@ -260,7 +260,7 @@ CMF_SEQ|CMF_RW|MD_CDL|MD_CSE|MD_REV| /* compare */ MD_SCH|MD_SEC|MD_SER, CMF_SEQ|CMF_RW|MD_CDL|MD_CSE|MD_REV|MD_CMP| /* read */ - MD_SCH|MD_SEC|MD_SER, + MD_SCH|MD_SEC|MD_SER|MD_RWD, CMF_SEQ|CMF_RW|CMF_WR|MD_CDL|MD_CSE|MD_IMM| /* write */ MD_CMP|MD_ERW|MD_SEC|MD_SER, 0, /* 35 */ But of course you want to fix Ultrix, don't you?

RE: [TUHS] SCO reveals major UNIXT IP violations

by norman＠nose.cs.utoronto.ca

Gregg C Levine: Kenneth, doesn't that mean, that their case can be closed, because they themselves are the guilty party? Caldera was bought by SCO. I thought it was the other way around: Caldera bought the UNIX-OS part of SCO, then (around the time the current fracas started) renamed themselves The SCO Group. Norman Wilson Toronto ON

SCO reveals major UNIX IP violations

by Kenneth Stailey

an excerpt: << SCO this week said it was "examining" the AT&T settlement to see who might have leaked the ancient AT&T-derived UNIX� code and put it into a BSD distribution. Allowing such hallowed innovations to be used under an open source license, would, we agreed thoroughly devalue SCO's IP assets. So we set about looking for who could perpetrate such a foul violation. And deep on a warez site of dubious origins, we unearthed a highly incriminating statement. There we found a script kiddie shameless boasting of his crime. The poster claimed that he'd released - "... the ancient UNIX releases (V1-7 and 32V) under a "BSD-style" license. I've attached a PDF of the license letter hereto. Feel free to propogate it as you see fit" Propagate? We shivered. The subject line of the email confirmed our worst fears. [...] So after a little digging, we traced this serious UNIX� violation to a hacker outfit called "Caldera Inc." The email was datelined 23 Jan 2002. Perhaps using an assumed identity, the hacker signed himself as "Dion L. Johnson II - Product Manager and one of many open source enthusiasts in Caldera Intl." We shall be doing some more digging soon, to see where these hackers can be traced. And as dutiful citizens, we shall inform The SCO Group of these violations as our enquiries continue. As soon as we find out who these Caldera hackers are. Can you help? >> complete article: http://www.theregister.co.uk/content/4/34102.html __________________________________ Do you Yahoo!?

SCO's additional law suits

Wonder where they are getting the money to do this? Who has the most to gain by shutting down BSD and LINUX? Brantley Coile

[pups] DEC PRO or P/OS

by Gregg C Levine

Hello from Gregg C Levine Can any of you point me in the directions of a website that completely discusses this operating system, PRO or P/OS? As I recall the DEC Professional system was basically a shrunken PDP-11. Finding one of course, would be a good thing. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

32I status as of 17 Nov 2003

by patv＠monmouth.com

1. Converted unpublished locore to AT&T syntax. Work still underway on new locore.S file. 2. Will use coff executable format. May comply with Sys V ABI. The latter is TBD. 3. Gcc is tool chain unless someone wants to take on 32V compiler. May take advantage of inline and asm in machine dependent files. I wouldn't recommend using the 32V compiler, mainly because there are so many syntax changes, as well as newer compiler technology, missing from it as to make it a very challenging project. 4. Gcc cross compile to be used for building. I'll make this available later next month, after I shake out the bugs. 5. May go to Bitkeeper for source control. More to follow. 6. License for all new files to be the "revised BSD license." This is compatible with the Caldera license, an "original BSD license" with the advertising clause specific to Caldera. I want to keep it open source, and this is the best compromise I see for project license. 7. May change spln() to more understandable nomenclature, e.g., spl4() becomes spltty(), similar to BSD practice. 8. 32I is the interim name. I would have preferred Unix version 7, but can't for obvious trademark reasons. Project name still up for grabs. I was thinking of UNX, named after the old DEC name for the facility I work in. Sort of a tribute to days gone by, as is porting 32V. Probably get into trouble for that one as well. --------------------------------------------- This message was sent using Monmouth Internet MI-Webmail. http://www.monmouth.com/

RE: [pups] DEC PRO or P/OS

by Fred N. van Kempen

Well, those programs emulate both the CPU (which *is* the same as those found in the PRO systems), but *also* the surrounding stuff like disk controllers, serial controllers and so on. It would not be (that) hard to add "PRO" emulation to SimH, if some sort of hardware specs are still available. cheers, Fred > -----Original Message----- > From: Gregg C Levine [mailto:hansolofalcon@worldnet.att.net] > Sent: Tuesday, November 18, 2003 2:56 AM > To: 'David Evans' > Cc: pups(a)minnie.tuhs.org > Subject: RE: [pups] DEC PRO or P/OS > > > Hello (again) from Gregg C Levine > I take it this means that the software written for those things, won't > run on an emulator normally running as a member of the regular PDP > family of machines?
