[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 This used to be at http://ghg.ecn.purdue.edu/vax/paper.html but for some reason Goble's pages have been withdrawn.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

[pups] Sums - help needed

by Robin Birch

This is rather off topic I know but the people in this group stand a good chance of being able to help, so apologies. Now, I am struggling with the sums involved in Reed Solomon encoding/decoding. Can anyone walk me through a couple of worked examples? Cheers Robin -- Robin Birch

[pups] Any SMP PDP11 platforms?

by Warren Toomey

Hi all, I stumbled across this reference to a 1975 Masters thesis: de Brito Meyer. W., and Hawley, J.A.. III. Munix. a multiprocessor version of UNIX. Master's thesis, Naval Postgraduate School, Monterey, Calif.. 1975. Description of dual processor Unix. Can anybody tell me what PDP11 platforms around 1975 had multi-CPU capability? Also, if anybody has further information about Munix, please let me know! Thanks in advance for any help. I've trawled thru the Unix Archive with no results. Cheers, Warren

Anybody with a copy of this paper?

by Warren Toomey

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?
