[pups] Advice on which PDP-11 processor handbook to buy

by Ross Tucker

Hello all- I'm a n00b on this list, so please forgive me my sins as I forgive those who.... uh, never mind. Anyway, I am looking to get a "PDP-11 Processor Handbook" from Amazon or eBay (so I can understand the Lions book) and there are so many different editions and versions... Lions writes about the 11/40, but supposedly, that's not too different from the /45 or /70. My simh boot images for v6 are for the /45 (though supposedly I'm supposed to be able to modify them to run on the others, right?). What I'm asking is your advice on which Handbook to buy. Here is a synopsis on the editions and prices from amazon: /04/34A/44/60/70 (1979) $10 /04/34/45/55/60 (1978) $40 /70 (1975) $16 /04, 24, 34A, 70 (Jun 1981) $16 /04/05/10/35/40/45 (1975) $45 What do you think? Thanks for your time, Ross

RAND editor e19

by Gunnar Ritter

Hi, does anyone still have the source code for the RAND editor e19 <http://www.rand.org/pubs/notes/N2239-1/>? One can read on the net that it was once available as public domain from ftp.rand.org, but this machine seems not available anymore. There is an archive rand.tar.Z in the 2.10 (BSD) directory of CSRG CD 1, but this contains the older version e14. I think it would be good to also have the final version e19 in the Unix archive. Thanks Gunnar

[pups] 2.11BSD Patch 445; FPSIM fixed; 211bsd runs on systems without FPP

by Walter F.J. Mueller

A note to all 2.11bsd users: Some time ago I looked into running 2.11bsd on systems without floating point unit. The release notes state that this is untested and unsupported, and indeed it didn't work. Robin Birch some time ago fixed part of the issues, see patch 434, but still the kernel paniced when the very first program was started. I managed to localize and fix the problem in sys/pdp/mch_fpsim.s. Steven Schultz right away issued 2.11BSD patch #445. All patches up to and including 445 are provided by Steven under ftp://sg-1.ims.ideas.gd-ais.com/pub/2.11BSD A patch level 445 system will now boot on simh for example on a set cpu 11/70 nofpp 4m configuration and work just fine, albeit a little slower. It should thus also work on a real 11/70 without FPP. I heard of some 11/70 with non-working FPP's, so this maybe good news for the owners. With best regards, Walter Mueller -- Dr. Walter F.J.

running unix v7 on a pdp emulator

by Karim Hamidou

Happy new year. My name is karim hamidou and i'm french (you've surely noticed that my prose isn't bright) and i'd like to run unix v7 on the pdp emulator sim-2.3. Do you know how to run it ? I hope that my question isn't quite inappropriate. Thanks for your help. Regards. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

V7 prompts

by Bill Cunningham

Hellwig, It's been a long time since I've been able to play with the simulator. Now I can't seem to get into V7. Can you point to me the page online because I don't have a .ps viewer that shows the commands again with the tapes and disks. tm(0,3) and so on. Bill

booting vanilla v7 on simh problem

by Abel

While looking for virgin/vanilla v6 and v7 tapes to boot on simh, I'm kinda stuck. And since simh mailing list wasn't much help, cuz seems there mostly vax/vms guys, maybe it's someone here to help me out. V6.tape from Ken Wellsch was quite easy to boot, by cutting three rk images directly from it by means of "dd", then booting the root image and mounting source and doc where it should belong. Also it boots nicely in more traditional way off the tape by using "ltap" script from "www.ba-stuttgart.de/~helbig/os" and then following the standard install procedure for v6. The same "ltap" set of commands or it's slightly shorter version like this one: d 100000 012700 d 100002 172526 d 100004 010040 d 100006 012740 d 100010 060003 d 100012 172522 d 100014 105737 d 100016 172522 d -h 100020 80FD d 100022 005007 run 100000 boots "catted" in one file Keith Bostic v7 bits of tape, up to the Boot : promt. But when calling mkfs or restor programs by "tm(0,3)" or "tm(0,4)", the simh just hangs indefinitely. Can someone explain what I'm doing wrong maybe?

Re: [TUHS] TUHS Digest, Vol 35, Issue 4

by lm＠bitmover.com

> for new code (and Sys V is mostly new enough, unlike Unix V32) after Hmm. I'm coming into this late so maybe I'm not seeing the full context. If the statement is that V32 != Sys V I have to disagree, I've read all of 32V source (kernel and user and I mean all of it. It's not like I had deep understanding of every line but my eyes have seen every line of code in 32V, it's not that big). I've also read large chunks of Sys V - not all of it, but depending on the release, fairly large chunks, like 80% or more. The idea that most stuff was rewritten in Sys V is not true, not even slightly true. I dunno if that is what is being claimed but if it is that's silly. Most of the stuff is the same, especially in userspace but also in the kernel, tons of the kernel is unchanged. -- --- Larry McVoy lm at bitmover.com http://www.bitkeeper.com

Open Sourcing IRIX?

by Lord Doomicus

Since SGI is EOL'ing IRIX at the end of the year, has anyone asked them if they would donate it's source ( under some sort of OSI license of course ) to the UNIX archive? Or is there too much SysV code in it? It would be cool to have easy access to the older IRIX versions for older SGI hardware. - Derrik Derrik Walker v2.0, RHCE lorddoomicus(a)mac.com http://www.doomd.net ...
