> From: Paul Ruizendaal >> the headers say they date from 1974-75. > Wow, that's great! That means that you have the initial version. The file write dates are May 1979, so that's the latest it can be. There is one folder called 'DTI' which contains an email message from someone at DTI to someone at SRI which is dated "10 Apr 1979" so that seems to indicate that that's indeed when they are from. (The message says that the folder contains the source for DTI's IMP-11A driver, which is different from UIll's, although they both descend from the same original version.) > Possibly it is V5 not V6 Nope, definitely V6 here. > All my leads for the 1975 version of this code base came up dry and I > feared it lost. I could have sworn that I'd seen _listings_ of the code in a UIllinois document about NCP Unix that I had found (and downloaded) on the Internet, but I can't find them here now. I did look again and found: "A Network Unix System for the Arpanet", by Karl C. Kelley, Richard Balocca, and Jody Kravitz but it doesn't contain any sources. > it may contain the first version of 'mbufs' It might - the code is conditionalized for "UCBUFMOD" all over the place. > Yes, a 'history' file seems to have been common practice at BBN.

All of which I have the source for - just looked through it. > If memory serves me, tjt wrote the assembler I have the NROFF source for the "A68 Assembler Reference", and it's by James L. Gula and Thomas J. Teixeira. It says that "A68 is an edit of the MICAL assembler also written by Mike [Patrick].". > Jack Test did much of the compiler and again IIRC that was based on PCC. I dunno, I'm not familiar with PCC, so I can't say. It definitely looks very different from the Ritchie C compiler. Noel

> From: Paul Ruizendaal <pnr(a)planet.nl> >> I have this distinct memory of Dave Clark mentioning the Liza Martin >> TCP/IP for Unix in one of the meeting report publihed as IENs > It may be mentioned in this report: > http://web.mit.edu/Saltzer/www/publications/rfc/csr-rfc-228.pdf Yeah, I had run across that in my search for any remnants of the Martin stuff. > Would you know if any of its source code survived? As I had mentioned, I had found some old dump tapes, and had one of them read; it had some bad spots, but we've just (this morning) succeeding in having a look as to what's there, and I _think_ all of the source is OK (including the kernel code, as well as applications like server Telnet and FTP). No SCCS or anything like that, so it's a bit hit or miss doing history - the file write dates were preserved, but of course a lot of them would have been edited over time to fix bugs, add features, etc. The tape appears to contains a _lot_ of other historic material, and it's going to take a while to sort it all out; it includes a Version 6 with NCP from NOSC/SRI, some Unix from BBN; a BCPL compiler; a 'bind' for .rel format files (produced by MACRO-11 and probably BCPL) written in BCPL; programs to convert from .rel to a.out and back; an early verion of Montgomery EMACS; another Unix from 'TMI' (whoever that might be); another UNIX that's somehow associated with TRIX; someone's early kernel overlay stuff; an early 68K C compiler, and also an early 8080 C compiler - just a ton of stuff (that's just a few items that grabbed my eye as I scrolled by). Algol, alas, appears not to be there (we probably didn't add it, because of space reasons). The copy of LISP on this tape seem to be damaged; I do have 3 other tapes, and between them, I hope we'll be able to retrieve it. Noel

> From: Nick Downing > This is a wonderful find Yes, I was _very_ happy to find those tapes in my basement; up till that, I was almost sure all those bits were gone forever. Thanks to Chuck Guzis, whose old data recovery service made this possible - he actually read the tape. > is it possible for you to read the other tapes also? Alas, they're all of the same system. So the most we're going to get is the files that are missing on this one due to bad spots on the tape. Noel

> some Unix from BBN This one is from 1979, it includes Mike Wingfield's TCP. The 'Trix UNIX' is a port to the 68K, probably started with something V7ish (I see "setjmp.h" in there). Bits of the Montgomery EMACS appear to date from 1981, but the main source files seem to be from 1984. I also have the source to 'vsh' (Visual Shell), whatever that is. Noel

Early TCP/IP: 3Com UNet

by Paul Ruizendaal

Just stumbled over another early TCP/IP for Unix: http://bitsavers.informatik.uni-stuttgart.de/pdf/3Com/3Com_UNET_Nov80.pdf It would seem to be a design similar to that of Holmgren's (NCP-based) Network Unix (basic packet processing in the kernel, connection management in a user space daemon). In time and in concept it would sit in between the Wingfield ('79, all user space) and the Gurwitz ('81, all kernel) implementations. I think it was distributed initially as a mod versus V7 and later as a mod versus 2BSD. Would anybody here know of surviving source of this implementation? Thanks, Paul

Package Management

by Henry Bent

The recent discussion of Solaris made me think - what was the first Unix to have centralized package management as part of the OS? I know that IRIX had it, I think from the beginning (possibly even for the GL2 releases) but I imagine there was probably something before that. -Henry

Oracle euthanizes Solaris 12, expunging it from roadmap

by Kay Parker

guess it is the beginning of the end of Solaris and the Sparc CPU: 'Rumors have been circulating since late last year that Oracle was planning to kill development of the Solaris operating system, with major layoffs coming to the operating system's development team. Others speculated that future versions of the Unix platform Oracle acquired with Sun Microsystems would be designed for the cloud and built for the Intel platform only and that the SPARC processor line would meet its demise. The good news, based on a recently released Oracle roadmap for the SPARC platform, is that both Solaris and SPARC appear to have a future. The bad news is that the next major version of Solaris—Solaris 12— has apparently been canceled, as it has disappeared from the roadmap. Instead, it's been replaced with "Solaris 11.next"—and that version is apparently the only update planned for the operating system through 2021. With its on-premises software and hardware sales in decline, Oracle has been undergoing a major reorganization over the past two years as it attempts to pivot toward the cloud. Those changes led to a major speed bump in the development cycle for Java Enterprise Edition, a slowdown significant enough that it spurred something of a Java community revolt. Oracle later announced a new roadmap for Java EE that recalibrated expectations, focusing on cloud services features for the next version of the software platform.

Was pcc ever ported to the CDC6600?

All this talk of targets for UNIX makes me wonder (given the eccentricity of the machine). N.

Working Group for Release of 8th, 9th, 10th Ed Unix?

by Warren Toomey

Now that we have quite a few ex-Bell Labs staff on the list, and several other luminaries, and with the Unix 50th anniversary not far off, perhaps it is time to form a working group to help lobby to get 8th, 9th and 10th Editions released. I'm after volunteers to help. People who can actually move this forward. Let me know if and how you can help out. Thanks, Warren
