boot block in v7 bootable on rp06 in simh

by Will Senn

In exploring v6, I have found some uses for having a running v7 instance... When I try to install the RP bootblock during the installation procedure for installing Version 7 Unix following the original documentation: ftp://ftp.uvsq.fr/pub/tuhs/PDP-11/Documentation/v7_setup.html I am unable to boot from the RP06 disk that I installed into the boot block onto via: dd if=/usr/mdec/hpuboot of=/dev/rp0 count=1 No error, it just hangs. I compared hpuboot to the bootblock at it matches byte for byte. I also compared it to the hpuboot file in Henry Spencer's tape image (I am using Keith Bostic's tape) and it matches that as well. I am asking this list because I thought y'all might know if there was a problem with: 1) the hpuboot binary on the tapes 2) v7 using RP06 3) something else helpful :) (maybe it's not supposed to be loaded to byte 0 on the disk image, although that's how it works with v6?) I am aware that the system can be booted from tape, but that seems hokey (obviously it works, since that's how the installation process works in the first place, but I think it is reasonable to expect to be able to boot from the RP06). Interestingly, there are and RL02 and RK05 v7 images that boot from disk available, but not RP. I will ask on the SimH list, if y'all don't think it's appropriately directed. Thoughts? Thanks, Will

Some notes on running UNIX v6 in 2015, using SimH and a healthy dose of documentation

by Will Senn

All, I am studying Unix v6 using SimH and I am documenting the process, as I go, as part of my own learning process. I have much to learn about Unix, Unix v6 in particular, the PDP architecture and its relationship with v6, and SimH's emulation of the PDP, so, I am taking notes... I thought that I would share the notes in raw form as occasional blog posts in the hope that the knowledge that I work to obtain, might be made available and useful to others. I also believe that these forms of communication, as insignificant as they may seem individually are part of helping to preserve the knowledge of our computing history, in the aggregate. Here is a link to the first post, a run at an installation walk-through: http://decuser.blogspot.com/2015/11/installing-and-using-research-unix.html I am open to feedback and criticism, but please keep in mind that I am a relative newbie to v6 and PDP land, some of my assumptions are probably/undoubtedly wrong, but definitely fixable :).

Well, for pretty much any _operating system_ (as opposed to applications), one will need to know something about the details of the machine it is intended to run on; depending on which part of the OS one is looking at, it will be more or less. E.g. switching processes probably requires a fair amount, since one needs to know about internal CPU registers, etc; whereas working on the file system, one probably doesn't need to know very much about the machine. > It will also require access to a lab where the ideas covered can be > experimented with. Actually, Lions/V6 was used in operating systems courses using simulated machines; one at MIT, 6.828 "Operating Systems Engineering": https://pdos.csail.mit.edu/6.828/ used it for a while before the students started complaining about being forced to learn an obsolete machine. They thereupon wrote a V6 clone for the x86 architecture, 'XV6' (see the top of that page), which is apparently now used for similar courses at quite a few other universities. > The v6 kernel ... packs in features that were either unavailable in > larger more established systems or may have been present in some form, > but were orders of magnitude more lines of code and attendant > complexity.

Hi, Don't forget the Zuse machines, which were later proven to be Turing complete.

You have to dig in the archives, but you want a version from Columbia circa 1977 and you be fine. The latest version will use things in the language first described in the white book - aka Typersetter C (Dennis was wrote the book starting with v6, but's not published until v7).

It's a lot of work and unless this is going to be a very long term thing, I'm not so sure it's worth it. As for the archivers which in the short term is likely to be your best bet: 1. tar - there a couple of versions of tar for v6 including binaries. I personally would start there. 2. cpio was written for PWB 1.0 which is v6 kernel based. That binary should run. But IIRC correctly the original cpio was only binary headers (the -c/ascii headers was added later). So you'll need to be careful on the modern computer and make sure you set the switches so that he created the proper endian/byte swapping -- ness in the header 3. tp/stp - on the original USENIX tape is a "super tp" that replaced the original one. The binary should run as is. The code for it is pre-K&R so compiling it with a modern compiler will be a little bit of work. Also, IIRC the "directory" which is on the front of the tape is binary, so you'll need to make sure you write everything in PDP-11 format. 4. ar - was updated by the community. Eventually, V7 took the "new ar" from original USENIX tape. Again that binary should just run fine. Although I don't think its directory is recursive so it may fail that requirement for you Clem

Installing a large set of files into v6 from a modern host

by Will Senn

All, I am trying to figure out how to get parts of 1BSD added into a pristine v6 install, but the question I have relates to moving more than a handful of files from a host system into v6, which lacks several capabilities that are taken for granted from v7 onward (tar, unzip, and so on). For background, in looking at the 1bsd tarball, exploded out, I saw that ex was available on the tape in a binary form that is suitable for a PDP-11/40 and I thought it would make life easier in v6 to have ex. So, I used dd to move the a.outNOID file onto a file, which can be used as a raw RK image and then off the RK image loaded in the PDP-11 into the v6 system as the executable file ex, and that worked. I was able to run ex (well, sort of, I get the colon prompt anyway... I haven't figured out how it actually works yet). Yeeha! Having had success of a sort with a single executable from the 1BSD tape, I would like to see if other parts of 1BSD will work in the environment and if I can properly install those parts. Individually moving files using dd is tedious in the extreme (there are many files in the tarball). I know there has to be a better way. Since v6 doesn't have tar, or unzip, it doesn't seem likely that using dd to move the tarball into v6 will be help matters. But, if there was a way to dd a subdirectory and its contents onto an RK image and get them off again into a useable v6 file system, that would work. My question for the group is based on the preceding discussion and the following assumption: 1. given a tarball such as 1bsd.tar.gz from the TUHS archive located at: /PDP-11/Distributions/ucb 2. with a running SimH PDP-11/40 instance with a virtual TU10 magtape with a virtual TU56 dectape with a virtual RK05 hard drive 3. running v6 as the operating system What is an efficient method of moving the files of the 1bsd distribution, or any other set of files and directories, into the v6 operating environment? Here are some approaches that seem reasonable, but that I haven't been able to figure out, if you know better, please do tell: 1. a utility on the host that is capable of copying a directory and its contents, recursively, onto a blank magtape/dectape/rk image that is then readable in the v6 environment 2. a tar and unzip binary for v6 that is capable of dealing with the tarball (but isn't the tarball going to exceed the max file size anyway, if so this won't work) 3. an alternative archiver that runs on FreeBSD or Mac OS X, that can create a single file archive from a subdirectory's contents on the host (the resultant file would need to be extractable on v6, and if file size is too limited, won't work either). 4. some kind of directory transfer utility that works over telnet that can be executed from a FreeBSD or Mac OS X host and that can be executed on the v6 system as well. 5. a utility capable of creating an empty magtape/dectape/rk image and another capable of making a filesystem on the image and another of populating the image (analogous to fdisk rkimage; mkfs rkimage; rkcopy dir rkimage) If I am asking the wrong questions, or thinking badly, I would appreciate a steer in the right direction.

Literally. You can't set the date to anytime in the 21st century, for two reasons. First, the 'date' command only take a 2-digit year number.

A few things I noted in your first post: > I am using the Ken Wellsch tape because it boots and is stated to be > identical to Dennis Ritchie's tape other than being bootable and having > a different timestamp on root. The only differences I could discover between the two are that in the Wellsch versions i) a Western Electric rights notice (which prints on booting) has been added to ken/main.c, and the Unix bootable images; and ii) the RK pack images do have, as you noted, the bootstrap in block 0. > Note: sh is critically important, don't muck it up :). The issue is > that if you do, there really isn't an easy way to recover. One should _never_ install a new shell version as '/bin/sh' until it has been run and tested for a while (for the exact reason you mention). Happily, in Unix, as far as the OS is concerned, the command interpreter is just another program, so it's trivial to name a new binary of the shell 'nsh' or something, and run that for a while to make sure it's working OK, before installing it as '/bin/sh'. > a special file (whatever that is) Special files are UNIXisms for 'devices'. _All_ devices in Unix appear as 'special files' in the file system, usually (but not necessarily) in /dev - that location is a convention, not a requirment of the OS.

Portable Pascal and a 1BSD question

by Will Senn

Hi all, In v2 no5 AUUGN Jun-Jul 1980, Andy Tanenbaum announced the availability of a Portable Pascal Compiler for the then proposed ISO standard. A tape was made for v6, v7, and non-unix platforms. Does anyone know if there is a tape image around that has the distro? On a related note, has anyone successfully installed 1BSD on a v6 install running in SImH? 1BSD has the Berkeley Pascal Instructional system on it. Regards, Will Sent from my iPhone

Re: [TUHS] tool (that wnj wrote?) that reduced the data segment size?

by Norman Wilson

I'm too tired to dig for the exact words in the ISO standard, but I had the impression that the official C rule these days is that the effect of writing on a string literal is undefined. So it's legal for an implementation to make strings read-only, or to point several references to "What's the recipe today, Jim" to one copy of the stripng in memory, and even to point uses of "Jim" to the tail of the same string. Or both. It is also legal for every string literal to reside in its own memory and to be writable, but since the effect is undefined, code that relies on that is on thin ice, especially if meant to be portable code. I have used, and even fixed (unrelated) bugs in, a compiler that merged identical strings. I forget whether it also looked for suffix matches. Whether the strings went in read-only memory was up to the code generator (of course); in the new back-end I wrote for it, I made them so. This turned up quite a few fumbles in very-old UNIX code that assumed unique, writable string literals, especially those that called mktemp(3). To my mind that just meant the programs needed to be fixed to match current standards (just as many old programs needed fixes to compile without error in ISO C), so I fixed them. I didn't (and still don't) like Joy's heavy-handed hack, but I see his point, and think it's just fine for the language rules to allow the compiler to do it hacklessly. Norman Wilson Toronto ON

tool (that wnj wrote?) that reduced the data segment size?

by Larry McVoy

I've gotten sucked into an embedded system project and they are running out of memory. I have a vague memory of some sort of tool that I think Bill Joy wrote (or maybe he told me about it) that would do some magic processing of all the string constants and somehow it de-dupped the space. Though now that I'm typing this that doesn't seem possible. Does this ring a bell with anyone? I'm sure it was for the PDP 11 port. Thanks, --lm

Re: [TUHS] "Edition 0" manual

by Doug McIlroy

> It's worth noting that Unix was built for troff. Typesetting patents if I recall correctly. This is a stretch. Unix was really built because Ken and Dennis had a good idea. The purchase of a PDP-11 for it was in part justified by the goal of making a word-processing system. The first in-house "sale" of Unix was indeed to the patent department for typing patents--the selling point was that roff could be made (by an overnight modification) to print line numbers as USPTO required, whereas that was not a feature of a commercial competitor. The timeline is really roff--Unix--patent--nroff--troff. Though roff antedated Unix, it did not motivate Unix. > Is this The UNIX Time-Sharing System, or related to it? The same > claim appears in the first paragraph: > https://www.bell-labs.com/usr/dmr/www/cacm.html This draft clearly dates from 1971.

Porting 2.11 BSD

by Oliver Lehmann

Hi, I wanted to at least give it a try porting 2.11 BSD to my Z8001 machine. I din't really wrote any kernel part until now so it will be a huge learning curve for sure. No idea what my spare time permits, but... at least I'm planning giving it a try. I didn't found something like "thing you should do first when porting 2.11 BSD to another architecture" online so I thought myself... maybe it would be good to start with the standalone utilities - more precisely with "disklabel". Is there a good "HOWTO" for "first things first" as implementing disklabel seems to require quite some "device work" before the first "hello world" is there - is there something else which should be could be done first and does not require so much to port (the whole disk subsystem on that machine is different from "usual" disk subsystems as it is handled via a PIO) Regards, Oliver

link() syscall implementation

by Oliver Lehmann

Hi, I'm struggling on reimplementing the C code for the link() syscall. Usually on SYSIII and V7 you have something like: link() { register struct inode *ip, *xp; register struct a { char *target; char *linkname; } *uap; [...] u.u_dirp = (caddr_t)uap->linkname; [...] } The problem now on my system is, u_dirp in the user struct is saddr_t (*long) and not caddr_t (*char) and I wonder how I have to assign uap->linkname. The original ASM code looks like: _link:: { dec fp,#~L2 ldm _stkseg+4(fp),r8,#6 ldl rr8,_u+36 [...] ldl rr2,rr8(#4) ldl rr4,rr2 and r4,#32512 ldl _u+78,rr4 [...] I had the same problem already 7 years ago but didn't came up with a solution back then. http://home.salatschuessel.net/quest/problems.php What came to my mind in the meantime is the following and maybe someone can check if this is right: 1. _u+78 (u.u_dirp) contains a pointer - so what is assigned here in ASM is a memory address. 2. The memory notation for accessing segmented data on Z8001 seems to be 0xSS00XXXX where SS is the segment number up to 127 and XXXX is the relative address in that segment. 3. This means ANDing 0xSS00 with 0x7F00 means to strip out all invalid data from the segment-position of the address, to make sure it can only be between 0 and 127 (0x0000 and 0x7F00). I wonder how the assignment of uap->linkname to u.u_dirp has to be done correctly?!

citation for a Bill Joy interview?

I see http://archive.org/details/BillJoyInterview but the source is unknown. Does anyone know who conducted this interview or where it came from? (I tried to contact the archive years ago but didn't hear back.) Most of the stories I have alternative sources for but I'd like to cite some of this content in a book I am authoring. Also it doesn't seem to have a starting place. It appears the beginning of the interview is missing. (Also it has eight sections marked with "[Skipped portion you requested.]" and 27 page breaks.) It appears it may have been OCR'd (Exacfiy = Exactly, correcfiy = correctly, f'mally = finally, f'md = find, f'n'st = first, llliac = ILLIAC, Riogin = Rlogin, HTrP: = HTTP: and many other OCR-like typos), plus misspelled names where the originally typed wrong (so I assume the transcriber wasn't directly related to this story, like deck = DEC, Favory = Fabry, Gerwitz = Gurwitz, "E-bid(?) ASCH" = maybe EBCDIC to ASCII). If anyone knows the source for this interview or a proper bibtex entry for it, I'd appreciate it.

VCF SE 4.0 - Speakers?

by Earl Baugh

Howdy, I'm the secretary of the Atlanta Historical Computing Society, and a lurker here on the TUHS list. We're starting our process of looking for speakers at our upcoming VCF SE 4.0. It'll be April 2nd and 3rd 2016 in the Atlanta area. Since I've enjoyed reading and hearing about all the UNIX history on this list, I was wondering if anybody here might be willing to speak at our event. It seems there is a good deal of history that is captured in the minds of the members of this list... which might make a number of good presentations. We're open on ranges of topics. We've had many different people speak... the first editor of Byte, the artist who did the covers of many Byte magazines, Jason Scott from archive.org, some early SWTPC engineers, some early Apple engineers including Daniel Kottke. We also have members from the various Vintage Computer groups from around the U.S. speak (and of course some local members), and some University Archivists who are starting to have to deal with old media. This year we will have Jerry Manock (the designer from Apple who established their design group...designed cases for Mac, etc.) as one speaker. We love to learn about the history, esp. from the folks who lived it. I am just slightly too young to have been there (was born in '65) but always enjoy the talks. We can accommodate from a 30 min talk to an hour. We have a professional sound set up and stage. We have a co-sponsor, the Computer Museum of America that is being established in the area as well. We have between 5 and 10 slots to fill. We aren't a large group, but we do have a limited budget to assist with travel, lodging, etc. We can handle "nice" but not the Ritz :-) If anybody is interested, please contact me and I can provide further details. And if you'd be interested but can't make this year, please still contact me, maybe we can work something out in the future. Thanks! Earl Baugh Secretary Atlanta Historical Computing Society.
