I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

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

by Walter F.J. Mueller

Hi Ross, you'll find on the Bitsavers Site (http://www.bitsavers.org) lots of documents, some handbooks under http://www.bitsavers.org/pdf/dec/pdp11/handbooks/ and the "PDP-11 Processor Handbook - PDP11/04/34a/44/60/70" under http://www.bitsavers.org/pdf/dec/pdp11/handbooks/PDP11_Handbook1979.pdf Under http://www.bitsavers.org/pdf/dec/pdp11 is quite a bit on various pdp-11 models, for example the "KB11-C Processor Manual (PDP-11/70)" http://www.bitsavers.org/pdf/dec/pdp11/1170/EK-KB11C-TM-001_1170procMan.pdf in case you'd like to go into details :).

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

by Kevin McQuiggin

Why not just download one from one of the many online archives? Most of them are in PDF format.

[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!
