[-- Attachment #1: Type: text/plain, Size: 599 bytes --] Is it okay for me to ask a question about Linux that's from '91~'92? Does anyone happen to have copies of H.J. Lu's Bootable Root and the associated Linux Base System disk images from the early '90s? I've managed to find a copy of 0.98.pl5-31 bootable root disk. But I can't find any base disks to go along with it. The files used to be on tsx-11.mit.edu:/pub/linux/GCC in rootdisk and basedisk subdirectories. Unfortunately all of the mirrors I'm finding of tsx-11 are newer, have the basedisk directories, but no image files there in. -- Grant. . . . unix || die [-- Attachment #2: S/MIME Cryptographic Signature --] [-- Type: application/pkcs7-signature, Size: 4013 bytes --]

I have to go look but I think I might have this on CD. I used to have a drawer full of install cds that went back to the 1990's. If I don't follow up, they are gone.

I looked, don't have it. There was a red 4 CD set, I want to say it was ImageMagick but that's the graphics program. It was a 4 cd set of at least one Linux distro and a boat load of open source stuff. It predated redhat so it was huge back in the day, way better to buy that than spend a bizillion days on ftp over a modem. H.J. Lu's stuff was on it. Does anyone know where he is? I can go look if that helps. On Thu, Jul 16, 2020 at 06:59:14PM -0700, Larry McVoy wrote: > I have to go look but I think I might have this on CD.

The CD collection was called InfoMagic, and when he posted his question on Twitter I was able to find a mirror here: http://grumbeer.dyndns.org/ftp/servers/sunsite/1994-06-28/GCC/basedisk/ As for the internet archive, the CD *might* be this one https://archive.org/details/cdrom-ldr-0694, these entries don't seem to be very well tagged or have listings of contents.
It was InfoMagic and that set is Linux Developer Resources. You can find
some releases of it on archive.org. I hunt it and similar sets to try to
reconstruct Linux libc release history.
But this is off topic for this list.

[-- Attachment #1: Type: text/plain, Size: 2229 bytes --] I usually think of him and Theodore Ts'o in the same context (which is to say, tsx-11/MIT), so perhaps he would know? LinkedIn claims he's at Intel somewhere in the Bay area, but his employment there dates (LinkedIn claims) to 2003...so, possible, or maybe he just dropped off the radar sometime between then and now.

Me too. For the record, I'm fine with Linux on this list but it is
probably up to Warren to decide.
I came from BSD roots, SunOS, but I've been using Linux since maybe
1994 or 95 as my daily desktop/laptop (and yes, it was pretty sketchy
back then, I've been playing with Linux since before it had TCP/IP,
it's gotten a lot better).
I think there are some legit complaints about Linux but a lot of those
could be said about BSD. Bell Labs Unix was very terse, they took less
is more as far as you can. Linux was far more pragmatic, the Linux
/proc is nothing like AT&T /proc, Linux is all strings and has tons
of info and knobs that /proc didn't have. AT&T /proc is about processes
and Linux /proc is a generic bunghole where you can see everything and
control everything. It's a bit much but in general, I like the Linux
/proc, it's pleasant being able to poke around without having the write
a C program to grovel through the binary data structures.
That said, /proc came from the time of 100mhz processors, the idea that
you were going to parse all those strings probably gave people heartburn
then. Now it is fine.

I count Linux as a Unix. It certainly ACTS a lot more like one (and did from day one) than, say, early AIX.
Early Linux was kind of where I came in, so I feel like I actually might have a bit to contribute if we’re talking about it here.

In my humble-but-correct opinion*, Linux and its origins fit into the general topic of UNIX history just as well as those of Research UNIX or BSD or SVr4.2.2.2.2.2.2.2 or SunOS or IRIX or Ultrix or Tru64-compaqted-HPSauce or whatever. It all stems from the same roots, despite the protestations of purists from all sides. Warren gets final say, of course, but to encourage him I will say: Ploooogie!

I agree but the purists will say linux is more like minux or other rewrites from scratch. All the other stuff listed below that isn't Linux, all traces back to v7, v6, etc. Given that Linux is so wide spread, yeah, it would be nice to have a place for old fuddy duddies like me to smack our gums and say "sonny boy, you and your fancy TCP/IP, a modem was good enough for me and it was uphill in both directions" :-) Actually, TCP/IP was awesome when we got it. Modems were better than nothing but they sucked until they were fast enough for SLIP.

This is what I have now (I can provide full listing): libc-5.4 - quite good coverage some versions only as a patch against previous version but I was able to find most original distribution source and binary archives libc-5.3 - most versions only as patch against older versions (this was short live series) libc-5.2 - not much of it was preserved on the net, again short lived series mostly patches but with wide gaps libc-5.1 - one of the shortest series (only 4 releases) again I have mostly patches libc-5.0 - first used ELF series. I have mostly diffs of it. with only one full release libc-4.8 - transitional release to ELF. there was only one version of it and I think it was never widely used in production. (you must be careful here as there is another libc4.8 series which is completely different) libc-4.7 - this was last official a.out series I've got most releases of it In addition to above I was even able to find CVS repository containing all changes from 4.6.27 to 5.4.46. Previous repository was unfortunately destroyed when computer of H.J.Lu crashed on April 6th 1994. Before version 4.7 thing get worse. These versions are oldest and they were not archived. Sometimes you can find bits of binaries of those versions in old Linux distributions but mostly on binary form. Another problem is that CDs started to be mass published only around 1993 and you will not find a lot of mirrors so old. libc-4.6 - I have only few full releases and just some bits like diffs of includes or release notes libc-4.5 - only some bits and patches. You can easily find CVS repository with commits of releases 4.5.7-4.5.19 (not development repository, just release by release pushed into CVS) as a side note same author created CVS repository of linux versions from LINUX_0_99_14 to LINUX_0_99_15I but these releases are quite easy to find libc-4.4 - again not much one full release and some bits libc-4.3 - one full release and some bits libc-4.2 - only some fixes from mailing lists libc-4.1 - it seem that I have source of it but nothing more Versions before 4.1 were released together with compiler libc-2.2 - only one release, nothing more libc-1.4 - I have some sources claiming to be package for gcc 1.4 from 1992 but I do not know its exact source (it contains copyright of DJ Delorie and I do not know if it was distributed with that copyright at that time). It seems to me that I found GCC binary for this library too but I was not able to test it. libc-0.12 - I do not know much about this version. I did not try to collect binutils for those libraries (I was mostly after sources) but as I tend to mirror whole tree I think I will get a lot of those too.

I just went down memory lane with the book "Rebel Code" by Glyn Moody. Good stuff. How different those days were, for me at least. I was just a Linux advocate, enthusiast, and hobbyist until 2000 or so, when I started work as a sysadmin. Red Hat Enterprise Linux was not yet a thing. It was just Red Hat, i.e. just another distro, just one voice of many that were shaping the future of the OS. Nowadays, in the corporate world at least, Red Hat IS Linux, or rather, Linux is whatever Red Hat says it is. That isn't entirely a bad thing. Gentoo is great for my personal use, in the same way that FreeBSD is. But if I have to support a few hundred servers, I'd rather do it with vSphere, RHEL, and Ansible. > [-- Attachment #2: Type: text/html, Size: 1883 bytes --]

Sorry for not responding on this thread earlier; I've been pretty swamped lately. Xiafs was introduced at about the same time of ext2; Wikipedia states that "Initially, Xiafs was more stable than ext2, but being a fairly minimalistic modification of the MINIX file system, it was not very well suited for future extension." The first part wasn't quite accurate. It turns out that xiafs had the same bug as ext2, but ext2 had the necessary sanity checking so that it actually issued a warning when the bug was triggered, where xiafs just silently corrupted the file system. The real issue was that xiafs was mostly a one-person show (namely Frank Xia) and he suffered blowback when he tried to rename xiafs to linuxfs, which was interpreted by many as a marketing effort --- about as tone-deaf as Stallman trying to jawbone people to rename "Linux" to "LiGNUx" ten years later. And xiafs was technically worse compared to ext2, and ext2 had a larger number of developers. So xiafs never really stood much of a chance. Also, by that point, very few people were actually using HJ's boot/root disks. Most developers had moved on to the MCC distribution by that time, since it was more comprehensive, and it was easier to bootstrap a working development system. So to be honest, I had never noticed that HJ was trying to use xiafs in his boot/root disks. Cheers, - Ted

Hum. :-/ To be perfectly honest, I hadn't heard of Xia-FS until I started messing with H.J. Lu's bootable root disk. I started messing with Linux in late '90s. By then, everything was ext2. > And xiafs was technically worse compared to ext2, and ext2 had a larger > number of developers. So xiafs never really stood much of a chance.

Lu's disk had largely fallen to the annals of history by '95. MCC and SLS had come and gone, being replaced with Slackware and Debian by the time that I started messing with Linux. > So to be honest, I had never noticed that HJ was trying to use xiafs > in his boot/root disks. I can't guarantee that H.J. Lu used xiafs for his bootable root disk. I want to say that he was using the minux file system. It's the base disk images that seem to be using xiafs.

I do have the boot/roots for kernel 0.99 pl 7 from my Yggdrasil disks of
July/August 1995 which I believe are also on archive.org. I used to have disks
from 1994 but they've been lost in time and I only have stuff from 94-97 now,
some of which are on archive.org already. Hope that helps.

Hello!
If it helps atll the strange people at Ibib managed to rescue the
collection that was running on the Linux distro side of the house, and
it's stored in their historic-linux directory.. Oh and the very early
Slackware stuff is available on the mirror of Slackware's FTP site on
the Mirror Services site at ftp.mirrorservice.org. Incidentally a very
early mirror of the TSX site is also inside that historic-linux
directory.

[-- Attachment #1: Type: text/plain, Size: 3664 bytes --] Super thanks I’ll take a look! I guess I should also say the attempt at bringing Mach to the Amiga saved a few bits of Mach when they were doing the Net/2 sub system, but then the lawsuit happened and as we all know academia and the world moved away from the microkernel thing (well except for Utah). But I guess now with the news of SeL4’s demise it’s basically all Linux and NT these days.

No, but I'd like to see it run on a Tahoe (emulator). Maybe my vote for
one of the most well known machines (due to BSD) that has seemingly
completely dissapeared off the face of the earth. Happy to be proved
wrong.
[-- Attachment #1: Type: text/plain, Size: 1128 bytes --] It took me years of on and off to finally figure out what the heck a Tahoe even was.

The Tahoe was a CISC machine, different from both the RT and the 3B2.
Those emulators might be useful as examples of how to write an emulator,
but they won't help you to boot any code.
I think there were several companies that sold Tahoe architecture
machines, but I don't remember any more.

Is there even a single shread of documentation though? It's a daunting
task trying to write an emulator based only on inferring the internal
workings of the machine from 4.3BSD source code. Mind, the end result
wouldn't be too interesting; hey it works... just like a VAX.

[-- Attachment #1: Type: text/plain, Size: 1621 bytes --] In the CSRG DVD set there is some cci ports of 4.2BSD… stuff is #ifdef’d Tahoe in there so it’s not hard to pick out but it doesn’t seem to have anything really documents looking. I could be 100% wrong though, but they just look like ‘clean’ source trees. Not sure if sanitized though. The assembler shows 182 opcodes … /* * Boot program... arguments passed in r10 and r11 determine * whether boot stops to ask for system name and which device * boot comes from. */ /* r11 = 0 -> automatic boot, load file '/vmunix' */ /* r11 = 1 -> ask user for file to load */ The stand/boot sounds awefully vax like with r10/r11… From: Clem Cole Sent: Wednesday, 26 May 2021 11:22 pm To: Lars Brinkhoff Cc: Jason Stevens; tuhs@minnie.tuhs.org Subject: Re: [TUHS] H.J.

It's a daunting task trying to write an emulator based only on inferring the internal workings of the machine from 4.3BSD source code. Mind, the end result wouldn't be too interesting; hey it works... just like a VAX. [-- Attachment #2: Type: text/html, Size: 4595 bytes --]

The CSRG folks at the time joked that the Tahoe (CCI) was a
"RISC": a Reused Instruction Set Computer.
A lot of the opcodes were the same as the VAX except that they
were nybble-swapped!
