Computer History Museum curator Dag Spicer passed along a question from former CHM curator Alex Bochannek that I thought someone on this list might be able to answer. The paper "The M4 Macro Processor” by Kernighan and Ritchie says: > The M4 macro processor is an extension of a macro processor called M3 which was written by D. M. Ritchie for the AP-3 minicomputer; M3 was in turn based on a macro processor implemented for [B. W. Kernighan and P. J. Plauger, Software Tools, Addison-Wesley, Inc., 1976]. Alex and Dag would like to learn more about this AP-3 minicomputer — can anyone help?

Re: [TUHS] Blit source

by Norman Wilson

I sense a hint of confusion in some of the messages here. To lay that to rest if necessary (and maybe others are interested in the history anyway): As I understand it, the Blit was the original terminal, hardware done by Bart Locanthi (et al?), software by Rob Pike (et al?). It used an MC68000 CPU. Western Electric made a small production run of these terminals for use within AT&T. I don't think it was sold to the general public. By the time I arrived at Bell Labs in late 1984, the Standard Terminal of 1127 was the AT&T 5620, locally called the Jerq. This was a makeover with hardware redesigned by a product group to use a Bellmac 32 CPU, and software heavily reworked by a product group. This is the terminal that was manufactured for general sale. I'm not sure, but I think the Blit's ROM was very basic, just enough to be some sort of simple glass-tty or perhaps smartass-terminal* plus an escape sequence to let you load in new code. The Jerq had a fancier ROM, which was a somewhat-flaky ANSI-ish terminal by default, but an escape sequence put it into graphics-window-manager mode, more or less like what had run a few years earlier on the Blit. By then the code used in Research had evolved considerably, in particular allowing the tty driver to be exported to the terminal (those familiar with 9term should know what I mean). In 1127 we used a different escape sequence to download a standalone program into the terminal and replace the ROM window manager entirely, so we could run our newer and (to my taste anyway) appreciably better code. The downloaded code lived in RAM; you had to reload it whenever the terminal was power-cycled or lost its connection or whatnot. (It took a minute or so at 9600bps, rather longer at 1200. This is not the only reason we jumped at the chance to upgrade our home-computing scheme to use 9600bps over leased lines, but it was an important one.) The V8 tape was made in late 1984 (I know that for sure because I helped make it). It is unlikely to have anything for the MC68000 Blit, only stuff for the Mac-32 Jerq. Likewise for the not-really-a-release snapshots from the 9/e and 10/e eras. The 5620 ROM code is very unlikely to be there anywhere, but the replacement stuff we used should be somewhere.

Re: [TUHS] Blit source

> If 5620s were called Jerqs, it was an accident. All the software with that > name would be for the original, Locanthi-built and -designed 68K machines. > > The sequence is thus Jerq, Blit, DMD-5620 Maybe the “Jerq” name had a revival. If the processor switch came with some upheaval it is not hard to see how that revival could have happened. The Dan Cross tar archive with the source code has two top level directories, one named “blit" with the 68K based source and another one named “jerq" with the Bellmac based source. The tar archive seems to have been made in the summer of 1985, or at least those dates are on the top level directories. I am of course not disputing that the original name was Jerq. There are many clues in the source supporting that, among which this funny comment in mcc.c: int jflag, mflag=1; /* Used for jerq. Rob Pike (read comment as you will) */

Blit source

by Paul Ruizendaal

I’m looking for source code of the original Blit as described here: http://doc.cat-v.org/bell_labs/blit/blit.pdf <http://doc.cat-v.org/bell_labs/blit/blit.pdf> It does not seem to be on the v8 tape. I found the following on the web: http://www.brouhaha.com/~eric/retrocomputing/att/5620/software/ <http://www.brouhaha.com/~eric/retrocomputing/att/5620/software/> but that seems to be from much later and for the 5620. Then there is this, which seems to be the Blit's graphics routines or a derivtive thereof: https://stuff.mit.edu/afs/athena/astaff/project/Sdev/S/src/fun/blit/ <https://stuff.mit.edu/afs/athena/astaff/project/Sdev/S/src/fun/blit/> (although it seems larger than the 8KB mentioned in the paper). I’m aware of this emulator: https://github.com/aap/blit <https://github.com/aap/blit> which uses a rom dump; it appears a good base for h/w documentation. Did the sources of these rom contents survive?

Happy birthday, Ada Lovelace and JFO!

by Dave Horsfall

Bit hard to classify this one; separate posts since COFF was created? Augusta Ada King-Noel, Countess of Lovelace (and daughter of Lord Byron), was born on this day in 1815; arguably the world's first computer programmer and a highly independent woman, she saw the potential in Charles Babbage's new-fangled invention. J.F.Ossanna was given unto us on this day in 1928; a prolific programmer, he not only had a hand in developing Unix but also gave us the ROFF series. Who'ld've thought that two computer greats would share the same birthday? -- Dave

Re: [TUHS] Gaming on early Unix

by Doug McIlroy

Moo and hunt-the-wumpus got quite a lot of play both in the lab and at home. Wump was an instant hit with my son who was 4 or 5 years old at the time. Amusingly, I speculated on how to generate degree-3 graphs for wump, but obviously not very deeply. It was only much later that I realized the graph always had the same topology--a dodecahedron.

Origins of PPP

by Paul Ruizendaal

I’m looking for the origins of SLIP and PPP on Unix. Both seem to have been developed long before their RFC’s appeared. As far as I can tell, SLIP originally appeared in 3COM’s UNET for the PDP11, around 1980. From the TUHS Unix tree, first appearance in BSD seems to be 4.3 (1986). Not sure when PPP first appeared, but the linux man page for pppd has a credit that goes back to Carnegie Mellon 1984. First appearance in BSD seems to be FreeBSD 5.3 (2004), which seems improbably late (same source). Paul

v10spell updated

by Arnold Robbins

Hello All. Anyone who pulled the code for v10spell that I made available a few months ago should 'make clean', 'git pull', and 'make'. A critical bug has been fixed for 64 bit systems, and the code has had some additional cleanups and the doc updated some as well. The repos is at git://github.com/arnoldrobbins/v10spell. Enjoy, Arnold

> From: Paul Ruizendaal > I'm looking for the origins of SLIP and PPP on Unix. Both seem to have > been developed long before their RFC's appeared. You're dealing with an epoch when the IETF motto - "rough consensus and running code" - really meant something. Formal RFC's way lagged protocol development; they're the last step in the process, pretty much. If you want to study the history, you'd need to look at Internet Drafts (if they're still online). Failing that, look at the IETF Proceedings; I think all the ones from this period have been scanned in. They won't have the detail that the I-D's would have, but they should give the rough outlines of the history. Noel

another conversion of the CSRG BSD SCCS archives to Git

by Greg A. Woods

I've been fixing and enhancing James Youngman's git-sccsimport to use with some of my SCCS archives, and I thought it might be the ultimate stress test of it to convert the CSRG BSD SCCS archives. The conversion takes about an hour to run on my old-ish Dell server. This conversion is unlike others -- there is some mechanical compression of related deltas into a single Git commit. https://github.com/robohack/ucb-csrg-bsd https://github.com/robohack/git-sccsimport -- Greg A.

FreeBSD retires gets()!

by Norman Wilson

We retired gets from Research UNIX back in 1984 or perhaps earlier, with no serious pain because replacing it wasn't hard and everybody agreed with the reason. I'm glad to hear some part of the rest of the world is catching up. We also decided to retire the old Enigma-derived crypt(1), except we didn't want to throw it out entirely in case someone had an old encrypted file and wanted the contents back. So it was removed from the manual and the binary moved to /usr/games. Norman Wilson Toronto ON

FreeBSD retires gets()!

by Dave Horsfall

Seen in the FreeBSD Quarterly Report: gets(3) retirement Contact: Ed Maste <emaste(a)FreeBSD.org> gets is an obsolete C library routine for reading a string from standard input. It was removed from the C standard as of C11 because there was no way to use it safely. Prompted by a comment during Paul Vixie's talk at vBSDCon 2017 I started investigating what it would take to remove gets from libc. The patch was posted to Phabricator and refined several times, and the portmgr team performed several exp-runs to identify ports broken by the removal. Symbol versioning is used to preserve binary compatibility for existing software that uses gets. The change was committed in September, and will be in FreeBSD 13.0. This project was sponsored by The FreeBSD Foundation. And the world is a slightly safer place... -- Dave

Irix on MIPS -- was kernel mode paged

by ron minnich

I'm looking for a reference to any Unix ports where the kernel ran in a non-paged address space and user mode was paged. I could swear this was done at some point, and memory says it was on a soft-TLB system like the MIPS, to avoid TLB pollution and TLB fault overhead. But maybe I'm nuts. I am happy to hear either answer.

Re: [TUHS] Someone wants to use an exabyte [ really bulk erasing ]

by Norman Wilson

I had a hand-held degausser, but lent it to someone years ago and never got it back. It was actually Exabyte that made me buy it. I bought a new 8505 through a reseller to supersede the 8200 I was using for home backups. It turned out the 8505's firmware refused to overwrite a tape already written at any but the highest density, so I couldn't reuse any of my existing backup tapes. Exabyte insisted it was a feature, not a bug. So I gave up and bought a degausser so I could turn a used tape into a blank tape so the damn tape drive would write on it. For further vintage-computing amusement: I decided to buy at that time because the reseller had arranged a deal with Exabyte: trade in any old tape drive, working or not, and get a couple of hundred bucks off on a brand-new 8505. So I gave the reseller an old, broken TK05 I had lying around. My sales contact for the reseller was a former service tech at the same company, so I figured (correctly) he'd get the joke.

Snotty remarks aside, I have a couple of Exabyte drives in my home world. They haven't been used for a long time, but when they were (for some years I used them as a regular backup device) they worked just fine. I've pinged the guy. Norman Wilson Toronto ON

Western Electric "Research Unix" License Contacts

Re: [TUHS] Western Electric "Research Unix" License Contacts

by Norman Wilson

Clem Cole: Al Arms wrote and administer the license BTW. ==== Aside for entertainment purposes: at one point, the root password for the UNIX systems I ran in the Caltech High Energy Physics group was derived from Al's name, but through a level of punning indirection. I believe Mark Bartelt came up with it. Later we decided to change it. I believe I chose the successor, which continued the UNIX-licensing scheme, but in a different direction: *UiaTMoBL The systems that had either of these passwords are long- since turned off.
