They're down the same mine as Jimmy Hoffa!! :-) But seriously, if you could find them, that would be fantastic. I've managed to collect (thanks Clem!) a tiny bit of info about them: http://gunkies.org/wiki/Able_ENABLE and I _think_ I've worked out how they worked, but more is better. We had a set of the prints at MIT BITD, but we didn't have the PROM/PLA/PAL/etc programming info, and one would need that too to reproduce them. > I sure hope there's a pdp11 sdcard / usb disk solution someday like they > did for the Commodore 64 So Dave Bridgham and I have been working on a QBUS card with an FPGA that uses an SD card to hold the bits, and emulates an RK11/RP11/etc controller. We have a wire-wrap prototype working (the RK11's done, the RP11 should be a short edit of that), and UNIX boots and runs. Now to turn it into PCB's... We've planned that the next step will be to do a UNIBUS version, which will also include ENABLE functionality (although it won't be plug compatible with an ENABLE, the memory will be on-board). Now to find the time/energy to make it happen... :-( Noel

Software Archeology: QED

by arnold＠skeeve.com

Hi All. I am starting to collect, if possible, different versions of the QED editor; with a hope to put up a git repo. If you have a tarball of code, please send it to me with as much info about it as you have. I would like to track down the qedbuf(1) man page also. I have contacted Rob Pike and got one tarball from him. I have another tarball that I got sometime in 1987 and have a promise of code coming Donald Mitchell. Much thanks! Arnold

System III on 11/34 + rl02

by Jacob Ritorto

Hi, Was wanting to put together a fully functional (meaning able to load the whole distro and recompile itself) and "reliable" System III machine made of real, albeit not terribly sexy parts. I have (4) working rl02 drives and an 11/34, so I feel like there's a chance it could work. I'll have to build it on the emulator, of course, then vtserver it over to the real hw in chunks. But the blocker is that System III only supports rl01, not rl02, which kills the 'full distro' prospect. Would anyone know if it's trivial to modify the source for the rl01 driver to just add double the blocks, thereby supporting rl02? Or am I wildly underestimating the task at hand? Has this been done before? Tips? thx jake

X11 Secondary Selection

by Grant Taylor

Does anyone know any history about X11's secondary selection? What did / still does use it? I'm fairly familiar with the primary selection and clipboard. But I'm not aware of anything that uses the secondary selection. -- Grant. . . . unix || die

Happy birthday, Peter Naur!

by Dave Horsfall

Computer science pioneer Peter Naur was born on this day in 1928; he was responsible for ALGOL60, BNF syntax (he notably insisted upon calling it Backus-NORMAL-Form), etc. -- Dave

Re: [TUHS] System III on 11/34 + rl02

by jnc＠mercury.lcs.mit.edu

> From: Jacob Ritorto <jacob.ritorto(a)gmail.com> > System III only supports rl01, not rl02 Really? That seems odd; SysII long post-dates (I think) the RL0x, if so it's odd they only supported the RL01. Looking at: https://minnie.tuhs.org//cgi-bin/utree.pl?file=SysIII/usr/src/uts/pdp11/io/… it seems to support RL02's: #define RL02 0200 /* bit 7 indicates an rl02 present if set */ > Would anyone know if it's trivial to modify the source for the rl01 > driver to just add double the blocks The only difference between the two is that the RL02 has twice as many cylinders, so there's an extra bit in use on the high end of the 'disk address' register. > From: Clem cole <clemc(a)ccc.com> > Also if you have a 40 class system like the 34 of 34A see if you can > find an Able Enable board. I'm sure there are a stack of them stored away with Jimmy Hoffa's body and the Ark of the Covenant in King Solomon's Mine! :-) Seriously, if anyone has one, I'd pay a very substantial sum for it.

IBM Mach 3.0 Ports

by Kevin Bowling

Does anyone have these documents or the ports themselves? Or know who to talk to so they can be preserved? https://www.cs.cmu.edu/afs/cs/project/mach/public/FAQ/rs6k_announce Regards, Kevin

Anyone have any luck trying to contact Micro Focus regarding Unix licensing?

by jsteve＠superglobalmegacorp.com

I've tried calling, emails to sales, using their website and I'm getting nowhere. I know this is more complicated than v6’s context switching …. I've also read that apparently Microsoft swooped in 2010 acting as CPTN Holdings and bought all the Novell patents and turned them over to GPL v2? I know after the whole SCO personal licenses and then Ransom Loves’s making 32v and all prior open was great but apparently it wasn’t his to give away. Or am I wrong? Are Unix licenses transferrable? Anyone know someone wanting to lease/loan/sell? I don't want to kick up too much of the hornets nest. I'd just hate to think that the original Unix is going to languish. I know many people worked so hard to keep the “Unix lights on”, just want to see that it doesn't die clouded in secrecy like VMS.

Ultrix Tape: Block Size?

by Warren Toomey

All, I received this request from Matthew who isn't subscribed to either the TUHS or cctalk lists. He knows how to read the lists archives. Many thanks for any help you can provide. Cheers, Warren ----- Forwarded message from Matthew Whitehead ----- Date: Mon, 15 Oct 2018 08:25:39 -0400 From: Matthew Whitehead Subject: Ultrix Tape Blocks Warren, I wonder if you can give me a referral. I want to install Ultrix-32 on my MicroVAX II using the ancient TK-50 tape drive. I know the tape files are on your archive, but I need to know the block size for each of the many files; it can vary a lot. Who might be able to help me with this? Matthew Whitehead ----- End forwarded message -----
