Newbie Question: How to Enable Local Logins on TSS/8

by robert.jarratt＠ntlworld.com

I have got TSS/8 running on SIMH (actually it is a ready-made image that I got for the PiDP8). I have set up SIMH to enable TTIX for a secondary line to connect another terminal, but when I try to login from another line (ie not the console) I get a message along the lines of a local login not being permitted. I have looked through the TSS/8 manuals on Manx, but I can't find anything that tells me how to enable local logins. Can anyone tell me how you do this? Thanks Rob

FTGH: COGNOS software kit

by toby＠telegraphics.com.au

Hi, I've had this box for a few years and wanted to see if it's interesting to anyone on the list. http://imgur.com/a/dm1vR Apparently everything but the software itself. :/ If there is genuine interest I can list the contents of the box. It won't be cheap to ship though. Located in Toronto, ON. --Toby

VAX Common Lisp

by john.h.blake＠gmail.com

I've been looking for it for a while as well, the only place I've seen that has it in any form is actually on the 11/780 running at the LCM (which you can of course access with a free account, if you just want to use VCL). I assume it must still exist elsewhere but it was removed >from the old software product libraries prior to any of the sets I've found archived anywhere, sometime around 90-91 I believe? There were several other CL and LISP implementations for VAX VMS but they've all fallen into the great memory hole as well. KCL in particular seems like it might be easier to find since it was freely available, but I've had no luck.

Unknown DEC indicator panel

by jnc＠mercury.lcs.mit.edu

> I suppose I should try and round up images of 19" x 5-1/4" PDP-10 > panels, too So there are quite a few, although I'm not sure they are exactly the same as the ones used in the PDP-11's, PDP-15's, etc. Those use a plastic bezel which is the same as the blank panels in the H960 racks, into which the inlay is set >from the front, and glued down to the lip inside the bezel. The PDP-10 ones, >from the pictures, and my vague memory, use metal bezels which cover the panels from the front, holding them on, so the shape of the inlay may be subtly different. Anyway, I found images (not great - all B+W illustrations in manuals) of the following PDP-1 panels: DF10 DA10 RC10 BA10 TD10 TM10 DS10 RM10B DC10 RP10-C MB10 MD10 I'll add them to the page at some point. If any has actual images of any of these, they'd be appreciated. (And no, none of them is the mystery panel in the RSTS manual.) Noel

Gould 32/77 (was: NWA auctions)

by rickb＠bensene.com

> I'm curious what the Systems 32/77 is.. >Wasn't Gould SEL? maybe an SEL system? The 32/77-series was a 32-bit machine implemented in ECL, based on earlier SEL designs, but is definitely Gould in design/manufacture. Some of the machines in the series had a very powerful (for the time) floating point unit (known as the IPU) that operated in tandem with the main CPU that vastly increased the number-crunching power available The machines were mainly intended for real-time control applications (as used in the flight sim applications in the auction) The machine ran a real-time executive called MPX-32. More information: http://www.encore-support.com/htmls/32_77.htm Years ago, I had some experience with these machines. They were quite powerful for their time, and were also workhorses that just ran and ran. Very robust design. These are neat machines, and I hope that they end up in the hands of someone that can care for them rather than ending up scrap. -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

VAX/VMS Pascal, Modula-3, Oberon, what could have been....

by seefriek＠gmail.com

I've heard Modula-3 (from DEC SRC and Olivetti Research Center) called "the Ada regular programmers would adopt". They never did, of course, because Olivetti decided research wasn't that important and DEC got bought and a lot of other reasons that are documented elsewhere. Not to get into a language pissing contest, but IMO it's an awfully nice way to program, with threading built in, type safety, generics, a reasonable GC, exceptions, etc. I really enjoyed it, but then I think Ada brings a lot to the table. What might have been, indeed.

Looking for info on a CAMAC module - Kinetic 3912 Unibus Crate Controller

by pete＠petelancashire.com

Over the years I've played around with a few old CAMAC (*) modules, by today's standard they pretty much have zero value, anyway that's another story. Recently I've been offered a CAMAC to Unibus board. A Kinetic 3912 Unibus Crate Controller . A Crate in CAMAC speak is just a chassis with a backplane. The problem with CAMAC is there is almost no information out there, Since I don't YET have a Unibus system, it more of a curiosity then anything. So .. anyone have the manual ?

QIC-150 1/4" Cartridge Drive with Emulex MT-02 SCSI-QIC Controller?

by rickb＠bensene.com

Hello, all, Question of the day: Will an Emulex MT-02 SCSI->QIC tape controller work with a Wangtek 5150EQ (QIC-150) Tape Drive? I am trying to resurrect an old Tektronix 4132 Unix workstation. The 1/4" Wangtek 5099EQ drive that was in the machine was toast, something on the drive's electronics went POP when it powered on the first time, and it is no longer being recognized by the MT-02 controller. I have documentation on the drive, and will probably look into seeing if I can fix whatever fried, but in the short-term, I have a Wangtek 5150EQ with a good drive wheel, and was wondering if this drive would function with the MT-02 and be useful on the machine. I have a bunch of old (1980's) QIC-24 tapes written with the old 5099EQ drive that I want to look through and archive in a different form. And yes...I know about the tension band issues with old 1/4" QIC media...I've got a bunch of new tension bands and have become quite adept at replacing them and assuring the proper tension on the tape. Wishing all a peaceful day, -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

VAX/VMS Pascal, Modula-3, Oberon, what could have been....

by mark＠wickensonline.co.uk

I recently discovered the very excellent website http://pascal.hansotten.com devoted to all things Wirth. I sent a message to the author, as detailed below, but I would encourage anyone to visit the website - you will surely learn something? Greetings from Windermere in the Lake District, England! I read with interest your interview with John Reagan. His efforts on the VAX Pascal Compiler, and more recently (well, in the last few years or so) my discovery of the very excellent Theo De Klerk book on VAX Pascal and it's excellent integration with the VMS operating system have rekindled my love of this excellent implementation of Pascal. I am the organiser of declegacy.org.uk - a 'mostly' annual event here in Windermere where collectors of DEC equipment and ex-employees gather to immerse themselves once again in the excellence of product that was the result of DEC Engineering. I have tried a couple of times to 'entice' John to provide a video narrative of his time at DEC - but, thankfully, he is still a very busy man. At DEC Legacy this time around for example I was very fortunate to find myself in the 'programming zone' for a couple of hours - sat at a VT terminal, trying to determine why my VAX Macro-32 fractal generation programme would not run successfully on a DEC Alpha via the VAX Macro Compiler. For those precious moments I could have been sat at a piece of DEC equipment anywhere in the world. For a programmer this is just intoxicating and all too rare these days. I have a long standing interest in the legacy of Wirth - and indeed DEC, as could be expected. When I was considering a programming language for my PhD efforts on a DEC 3000/600 AXP running Digital Unix 3.2C in 1994 I would have been better using Modula-3 and ignoring the C-based Khoros framework which was the path I eventual took (C was a 'better the devil you know' option at that point).

Along the same lines, the picture in the original PDP-8 manual was of a machine that had a front panel that looked more like the PDP-5 panel than the one shipped on the 8s. Given how close the machines were in architecture, it wouldn't be surprising for a prototype. As it turns out, I saw the picture in the manual a few years before I ever saw a real straight-8. To this day, the real straight-8s look a little "wrong" to me. BLS

[TUHS] Booting PDP-11's from RX02's

by jnc＠mercury.lcs.mit.edu

> From: Don North > Track 0 is not used by standard DEC software I wonder why DEC did't use track 0. The thing is small enough (256KB in the original single-density) that even 1% is a good chunk to throw away. Does anyone know? (I had a look online, but couldn't turn anything up.) If I had to _guess_, one possibility would be that track 0 is the innermost track, where the media is moving the slowest, and as a result it's more error-prone. Another is that IBM used track 0 for something special, and DEC tried to conform with that. But those are pure guesses, I would love to know for sure. Noel

Unknown DEC indicator panel

by jnc＠mercury.lcs.mit.edu

So, the CHM has an RSTS-11 brochure: http://archive.computerhistory.org/resources/text/DEC/pdp-11/Digital.PDP-11… which shows in a couple of places (front cover, page 6, 7, 10, 11) an indicator panel which I haven't been able to identify: it's the one where there are four full-length light rows on the left, and the lower right row of lights is broken up in the three groups - small, large, small. (The other indicator panel is known, it's an an RF11). I have been searching for these panels for quite a while now, and have a page for them: http://ana-3.lcs.mit.edu/~jnc/tech/DECIndicatorPanels.html _but_ ... I have never seen that panel. I am quite sure that it is _NOT_ an RK11-C panel; although no image of such has ever been found (I think because it was never produced - no DEC manual or print set refers to it), the RK11-C prints show the wiring for the connector to the indicator panel (which would presumably have been a standard DEC 19" x 5-1/4" panel of the kind documented on the page above), and from that it's possible to predict what it would look like, as shown here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/RK11-C_inlay.txt http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/RK11-C_inlay.pdf Can anyone shed any light (no pun intended :-) on what this is? The RF11 engineering drawings list (on page 187/188) all the inserts available (as of that date) for the standard 19" x 5-1/4" indicator panel, and I don't have pictures of all of them, so it's possible this is one of them. (It's clear from the brochure that this wasn't necessarily a working system, since it appears in a number of different configurations. So maybe they just grabbed up a random indicator panel and plugged it in to make the system look cool.) One possibility is that it's a prototype that was never produced - or perhaps it was the indicator panel for an earlier RK11 controller (although I can't find any mention of an RK11-B or RK11-A, and the list above doesn't contain an RK11 entry). Anyone have any ideas? Noel

If anyone could point me to a photo of the RC11/RS64 DECdisk panel > to be honest I don't know if it even had one? I'm not sure it did. The list of available inserts (in the Indicator Panel Assembly drawings, available in the RF11 prints, pp. 186-190) doesn't list an RC11 insert, and that list does include the RF11, which is a later controller than the RC11. I tried looking online for RC11 engineering drawings, to see if it included an indicator panel connector (the way the RK11-C does), but I could not find _anything_ substantial about the RC11 online. > From: Jon Elson > These look VERY posed, so don't be sure ANYTHING in the picture was a > fully working system. Yeah, I'd come to that conclusion... > If those panels look like something off a KA10 controller Well, I'm not sure. Most PDP-10 gear had rows of 36 lights, which is the full width of these 19" indicator panels (i.e. every light in a row - like the top row of the RP11 panel, see the page for an image), and I don't see that in this one. But I suppose I should try and round up images of 19" x 5-1/4" PDP-10 panels, too (ISTR that there are a few). Noel

I had a PDP-11/44 with batteries for the MOS RAM (and fans to cool it) with RK07 drives. I can remember testing it by pulling the power with a number of applications runnings including editors etc. The disks would yank the heads back and spin down, then when the power was restored and the drives spun up, it was like it never happened. I might see an entry or two in the error log file about a disk retry, and a user might loose a keystroke on the file they were editing but it absolutely was solid. I don't know of a single modern operating system that can do that today. RSX-11M+ can run TCP/IP today with Johnny Billquist's BQTCP package but it dies require I/D space processors. M+ itself can run on a 11/23+ or 11/24 but it really needs more than 128KW and the lack of I/D space really limits its capabilities. Mark

Pete: I've had pretty good luck during a data restoration project by ensuring the drive heads are clean and then also cleaning the cookie VERY GENTLY with good quality rubbing alcohol (I'm using 91%, some say you should use better stuff) on a cotton ball. My method has been to put the cookie on a clean, dry, soft surface. The disks I'm working on are Apple ][, so flippy (if the jacket is punched), otherwise I only need to concentrate on the "bottom" side of the cookie. Essentially, the side without the hub ring. I use a very fine-tipped needle top bottle (found it in the baking section of a local big-name craft store) and apply a reasonable amount of rubbing alcohol then use a fresh cotton swab and gently clean the surface. Depending on how it goes, I'll clean it a second time. Note, some of the disks look just fine, but still have some issue reading. This cleaning process has been highly successful (maybe 85%?) for me even with disks that looked clean. Also, on a few prior attempts I've had inexplicable results in trying different drives. I don't know if alignments, speeds, magnetic sensitivity or other factors were at play but it's worth trying as another trick to have in the collection. Sometimes it worked better, sometimes it was worse. I am not 100% sure, but I thought the "baking" was for media that was shedding or at some risk of having a physical issue with delamination, etc. Also, I can't really help on the merging question. I'd think you could just cut the resulting images together using a hex editor or similar. Naturally, you'd have to know where the bad parts were in the file. Maybe you could start with a 'fc /b filename.bin filename.bin' at a Windows command prompt, note the offsets of differences between multiple reads and visually compare those sections in a hex editor? Good luck with the data restoration! See ya. -Todd

Unix Version 1 was written in PDP-11 assembler, for the -11/20; although that was a re-write of an earlier version written in PDP-7 assembler. C was developed from B in good part because the word address model of B (inherited from its ancestor BCPL) wasn't a good match for the PDP-11's byte addressing model.

I'm going to _guess_ that it was the earlier caption; I definitely recall reading somewhere (maybe that history thing I already provided a link to) that when the PDP-11/20 first arrived, DEC didn't have a disk drive for it, and so it sat in a corner for some months (running some chess problem) until the disk arrived. So that argues that it was a very early production machine. Noel Noel - OK that is what I also read.... so probably would have said PDP-11 on the front panel not 11/20 if it was that early if we subscribe to the theory that the ones labeled 11 only were before the 11/20 I do wonder if there are any photograph of the system they used at the get go of the PDP-11 use? Need a photo that has definite date info.... yes, the systems are the same but some of this is important as I do the display cards for the 11/20 we have here at SMECC Thx Ed# _www.smecc.org_ (http://www.smecc.org)

At that time PDP-11 was a general architecture name and 11/mumble was a specific system. Keep in mind that new versions of the -11 would evolve soon after introduction and continue over time for decades. Add to that there were both processor naming and system configuration naming conventions. > I know they are essentially the same at this time point they got > their PDP 11 what did it say on the front panel I wonder? > (figuring all this stuff out for titling up the cards in the 11/20 > display we are planning.)

Altair, IMSAI, SWTPC, etc. for sale in Philly

by tosteve＠yahoo.com

--------------------------------------------------------------------------------------------------------*************? Contact Rick below if interested.? *************-------------------------------------------------------------------------------------------------------- Name: Rick Bunker????Contact: rick at bunker.us ????Location: Jenkintown, PA??? I have a computer collection that I have to sell. My wife and I have separated, and the house is being sold, and I have no place to keep the computers in my new apartment. It is a pretty nice collection. Altair 8800, two IMSAI 8080's, an Apple ][ (not ][+ or e or anything, the first one), a TRS-80 (the real first revision, with no numeric keypad, with the original cassette drive, monitor) an LSI monitor, a KIM-1, an original IBM PC (not an XT -- original 2-floppys, original bios), an SwTPC 6800 box, with no innards. Similarly, a Cromemco box with no innards. A Northstar Horizon. Some 8-inch drives, a bunch of S-100 boards, a luggable Kaypro portable, an odd and an end or two. Lots of documentation. Some old disks which may have readable software on them. I don't power these things up, since they have power supplies that you can weld with, with 40-year-old capacitors on them. Is there anybody in striking distance of Philadelphia suburbs, who would consider buying and picking up this collection? --------------------------------------------------------------------------------------------------------

> From: Allison > Later versions like 2.9 and V7 do want I&D. V7 is only distributed with pre-built loads for split I+D machines (so you can't boot a V7 distribution tape on a non-split machine), but it includes machine-language OS support files for non-split machines. (It's similar enough to V6 that it makes sense that it runs on non-split machines.) > From: William Degnan > Given 128K core, wouldn't one be able to save the OS in core, no need > to load what would need to "get started" from a diskpak? To fork a process, Unix swaps the forking process out, and then fiddles system tables so that one of the two copies (I forget which, without looking at the code) becomes the child. This includes at startup, when the 'swapping' process (0) splits and the child (1) is set up to run /etc/init. (I found this out the hard way, when bringing up V6 under Ersatz-11. :-) So Unix won't run without a swapping device. Noel

PDP11GUI 1.48.5

by j_hoppe＠t-online.de

Guys, there's a new release PDP11GUI 1.48.5 Some enhancements: 1. "Disk Image Read/Write": - Now compression of 2word patterns (32 bit patterns), did reduce download of a RSX-11 system disk from 40h to 6h. - Fix for PDP-11/44 console firmware v 3.40: ignore "(Program)" output after driver start. 2. Terminal windows now beeps on char, necessary for some endless XXDP diags. Download from https://github.com/j-hoppe/PDP11GUI/releases/tag/1.48.5 Web: http://retrocmp.com/tools/pdp11gui Enjoy, Joerg

Some pages from the 360-40 Development Manual, Hursley

by steven＠malikoff.com

I've pdf'd half a dozen pages of the 360/40 development manual from IBM British Labs at Hursley UK, early/mid 60s. I wish I had more but these only survived because dad used to bring home binders with these single-sided pages for us kids to draw on, and my parents kept them. They may not even be from the same document, but it's just for interest's sake. http://web.aanet.com.au/~malikoff/misc/IBM_360-40_Development_Manual_fragme…

DEC DS10L Fix CPUFan!

You never know until you try. Anyway, the Alphaserver 4100 has four midsize muffin fans and I found them trivial to take apart and trivial to replace the bearings which were a standard off the shelf part. It was easier to fix the fan than it was to replace them since DEC had a custom fan with a speed sensor built in that proved impossible for me to find. It changes from model to model and generation to generation. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black
