From: dwight <dkelvey at hotmail.com> > If we'd thought about it we could count to 1023 on our fingers. I used to play string bass in a symphony, and there were many times that there would be long periods of rest, where it was important to count the bars (measures) going by so as to come back in at the right time. To this day (that was 40+ years ago) I can still count quite rapidly up to 31 on one hand (either one). Higher numbers slow me down a bit... Old bass joke: During the last movement of Beethoven's 9th symphony, there is a very long tacit (rest) for the basses. So the bass section all went over to the bar across the street for a drink or three. To keep the conductor from passing by their entry, they put a rubber band around his music. So the situation was... Bottom of the ninth, basses loaded, score tied. (sorry...) ~~ Mark Moulding

Epson QX-10 hard drive

by imp＠bsdimp.com

Greetings I recently purchased a QCS external hard disk on ebay. This was one of the companies that was selling DEC Rainbow hard drives. I had hoped it was an old Rainbow drive with interesting to me bits... Turns out it is an Epson QX-10 hard drive, full of interesting to bits for the QX-10 CP/M enthusiast. I've had trouble finding a suitable community to note this in should there be people around that care... so I thought I'd ask here is people know of good CP/M groups and/or QX-10/16 groups, mailing lists, irc channels, discord servers, etc I could find.

This one has always boggled me, because it's the one aspect of the Endian Wars where there's a simple, straightforward answer grounded in basic mathematics - base ^ digit-number only gives the correct place-value when the lowest-order bit is numbered zero. It's beyond my ken how anybody thought the reverse was *valid,* let alone a good idea.

(I'm too burned out to look at the engineering drawings and get the part number to confirm; I'll do that 'soon'.) I took a picture of the male shells, and added it to the CHWiki page (I'll add the females tomorrow). The detail of the 6-pin one didn't show up too well, so I took another closeup of just it, here: https://gunkies.org/wiki/File:DECPwrConnMaleSml.jpg Your 15-pin is the same as mine (the part number matches). Your 6-pin has 'wings' on the side (these prevent it pulling through when placed in a hole in sheet metal); the 6-pin DEC used has little right-angle arms, just like the ones on the 15-pin, to brace it in place. They are compatible, though, I think; a female shell that will take one probably will take the other. Noel

Small DEC QBUS backplane

by nw.johnson＠ieee.org

I'm trying to repair an LSI-11/93 that has a bus timeout problem.? Unfortunately the BA23 box it normally sits in lives in a cupboard with printers stowed on top of it and due to my domestic situation (small condo) I can't get it out to scope or get a scope anywhere near it to scope the bus. I'm thinking that the solution would be to get a small QBUS backplane that I can put on my desk in the middle of my test equipment. Like a 4-slot ABAB oir even ABCD would do. Does anybody have one they don't want?? Power supply not needed. cheers, Nigel -- Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!

And, of course, "Don't waste space with more than two decimal digits for year. NOTHING that we are doing now will still be in use 30 years from now." One of the tasks that I was assigned (working for a contractor at GSFC) was to work on converting a wall of punch-card subroutines for plotting on Calcomp plotters that needed to be changed to work on Stromberg-Carlson (later Stromberg Datagraphics). It was budgeted for a LONG project to rewrite all of them. I realized that all of the subroutines for Calcomp called lower and lower level routines, on down to a small number of primitives. It was easy to write primitives for those lowest level ones, that worked on the SC/SD. I got some help with the JCL to link my primitives to the routines for the Calcomps. All of the routines for Calcomp worked fine calling their lower level routines, and ultimately calling MY primitives. The company got a small bonus for getting it all done way sooner than planned, and I got a private major reprimand for getting it all done way sooner than it was budgeted for. Many others earned bonuses for the company. The company distributed the bonuses as BIG bonuses to upper executives (I think that the top guy got a car), and gave each of us a gift certificate/coupon for a turkey.

Yes, the ones on the DD11-[C,D] (female shell, male pins) have 2 filled-in corners, and the ones on the harness into which they plug (male shell, female pins) have both the cutout corners (to match the filled-in corners on the female shells), _and_ "a square in the center of the side". As I said, I had verified that my female shells plugged into the male shells on an -11/40 harness; I just went and checked, those males have the exact identical shape to the ones I got (with the listed part number), including both cutout corners and the square in the center of the side. (Oddly enough, the 15-pin male shells used in that generation of DEC power connectors do not have the square in the center of the side, just the cutout corners.) Noel

Want To Buy: HP 9817 Monitor and Keyboard

by tangentdelta＠protonmail.com

I have an HP 9817 and 9133D disk drive that I am trying to get going. The 9817 has a 98204B composite video card. I can mess with the settings of a composite monitor enough to barely read the text on the screen, which indicates that the machine is trying to boot from device A. I tried to make an image of the hard drive in the 9133D using Dave's MFM emulator, but the drive is pretty much toast and I wasn't able to recover much from it. If I connect the drive to the computer, it fails to boot and goes into BASIC. I do not have a compatible HP monitor or HIL keyboard to use with the machine. I was planning on building a PS2 to HIL converter, but having an actual keyboard would be far easier. Likewise, having a monitor would be easier than abusing a normal composite display into working. It looks like there were a bunch of compatible monitors back in the day. The 35721 and 35731B are mentioned on the HP Museum website.

DDCMP sync?

by paulkoning＠comcast.net

In playing with DECnet I built a DDCMP implementation which deals with a byte stream, normally from a UART. So that works nicely with async link DDCMP as found in RSX and several other operating systems. But the speed is limited. The other option would be synchronous links, which would enable connections to DMC11 or the like at speeds up to 1 Mb/s. But synchronous comm devices that connect to modern computers aren't so easy to find, though I have seen a few. After playing with Arduino for LK201 keyboard emulation I started to wonder if one could be made to be a synchronous comm link with a USB back end, with low level things like byte framing and maybe DDCMP packet format handling in there, but the protocol state machine in the host behind the USB interface. For moderate speeds that seems entirely practical. For 1 Mb/s, probably not, though perhaps one of the fast ARM based units with its built-in SPI could be warped into that. The alternative would be something like a BeagleBone Black (or Green) such as David Gesswein used as the engine for his MFM hard disk emulator. That clearly could do the job without any strain. So I'm wondering: would there be interest in such a thing? If yes, should it be a modem-connected one (RS232 signaling, bit clock supplied externally by a modem or modem-eliminator)? Or should it be the "integral modem" short distance type, the ones that used a pair of coax with 4-pin AMP connectors like this https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/2… ? paul

DEC part number system

by jnc＠mercury.lcs.mit.edu

So, DEC part numbers (xx-yyyyy-zz) have a system where the 'xx' says what _kind_ of part it is; e.g. bootstrap PROMs are all 23-xxxxx-yy. I seem to recall reading at some point something which listed all the xx- codes, and what they meant - but now I can't find it. A Web search didn't turn it up, and it's not in the 1974 'engineering handbook'? Does anyone recall seeing it, and if so, where? Obviously, I could look through a bunch of print sets, and reconstruct it (e.g. 90- seems to mean mounting hardware - nuts and bolts, etc) but I'd rather not put the time and energy into reconstructing the wheel, unless there's no other way.

50 free 8 inch floppies!

by cz＠alembic.crystel.com

Ok, with the RX02 running I see that 50 of these disks from Solarex were formatted with the FD: driver which is probably the MXV21 controller. Since I don't have a 5.4 version of this driver and to be honest will not be putting the MXV11 controller online anytime soon I'm offering these disks for free. So if you need 50 disks with various versions of RT11 and god knows what data on them or 50 frisbees let me know and they're yours for the cost of shipping. I need to either pitch these things or give them away. Thanks! Chris

Modifying a RXV21 for an 11/83

by cz＠alembic.crystel.com

So I found an RXV21 board in the pile of stuff here and popped it into my 83. Crashes the system. It's an M8029 D board, and I see from this site that you have to add a few traces and cut a few others to make it work on an 11/73 or better. http://www.chdickman.com/rx02/ I'll pop in an 11/23+ CPU just to test it, but is it really just putting in two wires on the top of the board and cutting a total of three traces? Looks simple enough... C

I had read of it, of course, but for me the revelation was getting an Acorn Archimedes in 1989, with an 8MHz ARM2, and seeing it blast past benchmarks of ~8MHz 68K machines such as the Amiga 500 or Atari 512 ST. It was about 4x faster, I believe. For me -- being a bit too young for the early days of the 68K family -- it was not a performance chip, but more about its ability to have lots of flat memory, unlike the crippled Intel chips that IBM used. > Weird that Rod Coleman had 68000 > instruction set associated with IBM 370 whereas > to me it was very PDP-11 like I've heard that before, yes,. and never the IBM comparison.

Sinclair's QL used a 68008 and was launched some weeks before the Mac. Of course Apple's own Lisa was before the Mac, too. Very soon after came the Amiga and ST -- the "Jackintosh", "power without the price." -- Liam Proven ?

DEC Pro operating systems and MFM emulator

by paulkoning＠comcast.net

The question was asked (I misplaced the note) if the OS images that are on the Xhomer website work with David Gesswein's MFM emulator on real hardware. You can turn these into emulator data files, provided you have the latest ext2emu tool that's part of David's software (as of 1/19/2021). The format needed is "Elektronika_85" which is the Pro format, called that because it was first added to the emulator as the format found on the Russian bootleg copy of the Pro of that name. Results, on my Pro 380: 1. P/OS 3.2: works. 2. Venix: panic at boot, "Bad access number". That doesn't mean anything to me. I wonder if the issue is that Venix doesn't support the 380. 3. RT-11 5.3: works. For grins I tried a smaller interleave factor than the default 5:1, since it seems reasonable that this should make things go faster on the Pro 380, given that its CPU is about 4x the speed of the one in the Pro 350. Somewhat to my surprise this isn't the case; the performance indicates that at 4:1 or smaller interleave the software misses the next sector and has to wait for another revolution. paul

HP 3000, APL\3000, the HP 2641A APL Display Station, and stuff.

by gavin＠learn.bio

As some people here are aware, I have spent probably too much time this summer hacking on J. David Bryan's excellent Classic HP 3000 simulator and trying to build up the ultimate classic 1980s HP 3000 system (virtually speaking). I started with the MPE V/R KIT that's widely available and expanded that into a 5x120MB HP 7925 disc system and configured things like the system directory size and all the system tables to make a fully functional multi-user server. I then set about collecting as much old MPE software as I could find, which included Keven Miller's collection of the old Contributed Software Library tapes which were conveniently available in SIMH format. This is a huge trove of cool stuff including most of the classic mini/mainframe games (Dungeon, Warp, Advent, etc., etc.) and even a little game called DRAGONS that was written in 1980 by a guy named Bruce Nesmith when he was in college and he used it to get a job at TSR and went on to write parts of many classic D&D products and eventually landed at Bethesda where among other things he was the lead designer for another little game called The Elder Scrolls V: Skyrim. I was able to track Bruce down and give him a copy of the system with his 40 year old game running on it. The CSL tapes also include other amazing goodies that people developed and gave away over the years, including a FORTH and LISP, as well as most of the system and utility programs that people used to run their 3000 shops. It's quite fun to explore. I was curious how far we could push the 3000 simulator, so I hacked all the memory bank registers to be six bits instead of four bits, and we now have a simulated HP 3000 Series III that supports 8MB of memory, 4x more than any physical system ever did. I started trying to do the same thing for giant disc drives, but MPE turned out to have too much knowledge of what the supported disc models look like to make it practical. Bummer. Since I met my first HP 3000 in 1980 (40 years ago this month), people would talk about what was probably the most rare and exotic HP software subsystem ever produced, APL\3000. APL on the 3000 was a project started at HP Labs in Palo Alto in the early 1970s. They were likely motivated by the success IBM was having with mainframe APL timesharing services. This would be the first full APL implementation on a "small" (non-mainframe) computer. It would be the first APL with a compiler (and a byte-code virtual machine to execute the compiled code), it would include an additional new language APLGOL (APL with ALGOL like structured control statements), and it managed to support APL workspaces of unlimited size through a clever set of system CPU microcode extensions that provided a flat 32-bit addressing capability (on a 16-bit machine where every other language was limited to a 64KB data segment). Because APL required these extra special CPU instructions that you got as a set of ROM chips when you bought the $15,000 APL\3000, and because APL ultimately failed as a product (another story in itself) and thus HP never implemented these instructions on their later HP 3000 models, I never saw it run on a real HP 3000, but over the years we talked about wouldn't it be cool to find a way to get APL running again. With assistance and moral support from Stan Sieler and Frank McConnell and others, I was ultimately able to reverse-engineer the behavior of the undocumented ten magic APL CPU instructions needed to get it to run and implement them as part of the MPE unimplemented instruction trap and now APL\3000 runs again for the first time in ~35 years. Somewhat ironically, this implementation method could have been used back in 1980 as I didn't actually end up changing the hardware simulation code at all, and it should also run (if a bit slowly) on any physical classic architecture 3000. So that was cool and all, but what is APL without all the weird overstruck characters and whatnot? APL\3000 supports the use of plain ASCII terminals through blecherous trigraphs like "QD for the APL quad character, but this is hardly satisfying. So the quest was on to find a solution. Back in 1976 when APL\3000 was released, there was a companion HP terminal in the 264x line, the HP 2641A APL Display Station, which was basically an HP 2645A with special firmware and APL character set ROMs that supported all the APL special characters as well as overstrikes (the terminal would take X<backspace>Y and lookup to see if it had a character to represent Y overstriking X and if so it would show that on the display, and if that got transmitted to the host it would convert it back into the original three character overstriking sequence). I briefly looked into the idea of hacking QCTerm or Putty or something, but then I found out from Curious Chris that an HP 2645A emulator already existed in the MAME emulator system! Since the '41 is basically just a '45 with modified firmware, and Bitsavers had both the character set ROMs as well as the firmware ROMs from a '41, this sounded like it might be easy! There was a snag however in that the firmware ROM images that were allegedly from a '41 turned out to actually be from an ordinary '45. But we did have the character sets and one of the ROMs from the second CTL PCA. I put out a call on the Vintage HP list to see if anyone might possibly have a lead on an actual HP 2641A, and Kyle Owen responded that not only did he have one he could also dump the ROMs for us. So a few days and a few hacks to F. Ulivi's MAME hp2645 driver later we now have a functioning MAME HP 2641A terminal emulation, so you can experience APL\3000 in all its original glory. I bundled up a somewhat stripped down MAME along with my turnkey 3000 setup so both emulated HP terminals are just a couple clicks away. So that's how I spent my summer vacation (who am I kidding, it's pretty much all vacation these days). It has been a lot of fun revisiting all this old 3000 stuff as well as the numerous people I talked to along the way including some of those who were around at APL\3000's birth (before my time). It was rather a lot of work so I'd like to feel it might be useful to someone in the future who is digging into this part of history. Because of all the usual reasons, I don't plan on hosting it permanently until and unless we maybe someday get the licensing worked out (the 50th anniversary of the HP 3000 will be in a couple years so maybe people will get interested again then) but I will offer it up here to my fellow computer history nuts if you want to help ensure that it doesn't vanish if I get run over by a bus or something :) This is a simulated HP 3000 Series III (circa 1980) running MPE V/R (circa 1986) with 8MB of memory, all the language subsystems (APL, BASIC, BASICOMP, RPG, FORTRAN (66), SPL, PASCAL, COBOL (68), COBOL II (74)), 20 years of users group contributed software, many classic historical computer games, etc. Software archaeologists can get lost in here for years. Oh, and thanks to Dave Elward, the HP 2000 Timesharing BASIC contributed library is even included (kinda sorta converted to MPE BASIC) for good measure. This is a streamlined turnkey edition that's ready to run out of the box with no assembly required (all batteries are included). Currently, I only provide executables for Windows (sorry) but am in the process of getting the 3000 simulator changes (for large memory support) and the new MAME hp2641 driver back upstream. Instructions and further details can be found in the README.txt hint book for this adventure. 94MB Google Drive link: https://drive.google.com/file/d/1bmXvHkBLbUeLAid73EJ4H1yQ2uwXQuRu Gavin P.S. I'm giving a talk on the history of APL\3000 and its resurrection to the ACM APLBUG group in a couple weeks. If anyone is interested I can provide more details when I have them.

Well, with Dave's help we got the DSM-11 disk to boot on SIMH. Oddly enough SIMH seems to read a raw RQDX1/2 disk pretty well. sim> attach rq0 dsm.dsk sim> set cpu 11/73,1m Disabling RK Disabling HK Disabling TM sim> boot rq0 Booting DSM-11...

DEC Pro 3xx archives

by paulkoning＠comcast.net

I recently ran into an archive of various Pro 300 items, mostly from DECUS I believe. That includes a full P/OS 3.2 distribution including (!) DECnet/Pro if I saw that right. It's at ftp://ftp.update.uu.se/pub/professional/ What makes things somewhat painful is that it's LHA compressed Teledisk images, which is an ancient DOS based floppy imaging tool. The instructions say to run Teledisk on a DOS system with a 5.25 inch floppy drive to write the images to RX50 floppies, which can then be used. If you don't have DOS handy, or would rather get floppy image files for use with Xhomer, this can work but it's a bit painful. I found there's a simpler way. 1. Decompress the LHA files. On a Mac, the unarchiver (I think that comes with the OS?) handles that format. On other operating systems, I assume it's equally straightforward to find a tool that handles this. You now have a pile of *.TD0 files, which are the TeleDisk format files. 2. From http://www.seasip.info/Unix/LibDsk/ install LibDsk 1.5 (not 1.4). 3. Use the dsktrans tool you got from step 2 to convert each *.TD0 file to a raw image, like this: dsktrans -otype raw PRO177/177-21.TD0 proinstallv32.dsk "raw" format means a straight sector dump in physical order; this is the format expected by xHomer. If for any reason you want a logical order image, for example to give to the SIMH "rq" device that emulates an RQDXn controller, you'll need a tool that reorders things. I have one in my RSTS file system tool "flx" (V3 in Python, not the earlier 2.6 in C), "rx50.py". I can supply more details if needed. paul

cc:Mail version numbers

by tomas＠basun.net

People, I'm trying to wrap my head around cc:Mail version numbers. Various products such as Mobile and Gateways have their own separate series of numbers, but the main products seem to be as follows. Release Database Appeared in 1? ? ? 2? 6? ? 3? 6? ? 4? 6 ? 5 6 1995 6 8 1996 7? 8 ? 8 8 1997 I saw someplace that I cannot find now that DB6 is from 1989. Can anybody fill in the missing numbers? So for example, there is a package on Ebay right now https://www.ebay.com/itm/LOTUS-ccMAIL-in-original-box-diskettes-manuals-Win… that seems to say `Release 2.01' and 1993. How does that compute? /Tomas

David Gesswein's MFM emulator on the DEC Professional

by paulkoning＠comcast.net

I just completed a set of tests of David's MFM emulator on my Pro 380. Summary: everything works right. Very impressive device. My compliments to David for an amazing piece of engineering. Details: 1. I built and tested it (rev C board) per the instructions and all that worked nicely. A few minor points in the instructions, quickly clarified by David and already updated on the web page. I used an old 2 MB BeagleBone Black (the kind that was shipped some years ago with the abandoned Angstrom distribution), that fits just fine. 2. I read the three drives I have, one RD51, two RD52 (Quantum). All worked fine. They were identified by the analysis tool as "Elektronika_85" which makes sense since that's a Pro clone. 3. On the RD52, the last cylinder cannot be read. The reason is that the DEC standard formatting tool does not format the last cylinder except on the RD50. I'm not sure why; the comments say it is "reserved for the FCT" but I don't know what that is. In any case, ignore those errors; the OS does not use that cylinder so nothing bad happens. 4. In spite of what the XHomer documentation says, Pro disks have 16 sectors per track, not 17. It may well be that the drive is physically capable of holding 17 sectors per track if you have an RQDXn controller, but the Pro format is definitely 16 sectors. And 4:1 interleaved to account for the performance issues of programmed I/O rather than DMA. 5. I set up auto-start of emulation mode using one of the files created by the disk reader. That works fine, the OS boots, identifies the drive type correctly, and runs happily. 6. I also tested creating a new empty RD52 image (i.e., 512 cylinders, 8 heads), and running a P/OS 3.0 install to that emulated disk. That works also; as Chris Zach suggested, the installer includes a low level formatter tool and invokes that automatically when it detects it is needed. 7. Poweroff data saving works nicely. I can watch the BBB keep running after I turn Pro power off, then after 5-10 seconds the BBB power light also goes off. 8. I looked at the extracted data files created by step 2: they are good block level data images of the disks. A note on testing and drive copying: at first I tried to do this using a spare Pro power supply. That does not work because that supply requires a substantial minimum current. Even with a real drive plugged in alongside the emulator, the current draw is too small and the supply shuts down almost immediately. Instead, I temporarily connected an old small PC-type power supply I had lying around (rated at 50 watts according to the label); that was plenty for the emulator and also good enough to power it along with the drive to be read. paul

Looking for old Compaq software - COMPAQ System Manager Facility

by matti.nummi＠hotmail.fi

For a workaround: 1. Solder any same size pot with suitable long wires to the location (if possible) 2. Adjust the brightness to Your liking 3. Remove the pot 4. Measure the resistance 5. Solder a measured value resistor where the pot was. This way You get a fixed brightness and somewhat working computer. Now You can wait for a replacement pot and play with the computer. BR Matti

DEC: securing 15V pwr monitor board in H765 supply

by fritzm＠fritzm.org

Hi all, I?m reassembling an H765 supply after cleaning and repairs. It has the "newer" style 15V and power monitoring board (the one with the edge finger connector, same as used in H7420 supplies.) The board slides into a slot in a sub-chassis that also houses the power control circuitry, which small chassis later slides into, and is secured to, the larger H7420 chassis. I cannot for the life of me figure out what, if anything, secures the power monitor board to the small chassis! There don?t appear to be any conveniently placed fixtures to which to screw down the board, and I haven?t been able to inform myself by pondering the various engineering diagrams, IPB?s, nor the pile of remaining fastening hardware... When I test-fit everything in the larger chassis, the unsecured board is held captive only by the grace of the surrounding wiring harness and by some small clearance issues with the large cap on the board. This doesn't seem satisfactory; as part of something like an 11/34 on tilt slides, it would seem to bang around a bit in there if left loose like that. Am I missing something? Puzzled... --FritzM.

DEC Pro hard drive formatter

by paulkoning＠comcast.net

I'm wondering how to do hard drive formatting, which is likely to be needed when working with emulated disks in David Gesswein's MFM emulator. As far as I can tell, RT-11 can do this. At least I have a source code printout for such a formatter. But while I can find a hard drive image of RT V5 for Pro, I haven't found any floppy-bootable images. And I think it's a bit tricky to create one. I knew, long ago for V2... Any suggestions? Any alternative sources for a formatter? I guess I really should consider typing in the core of that formatter and adding it to RSTS. paul

ICL PERQ 2 T2 Micropolis 1303 spinning down.

by mattislind＠gmail.com

I have a nice ICL PERQ 2 T2 that I am going to start working with now. First thing was to try to image the hard drive. It is a Micropolis 1303. It spins up but when it reaches what I think the correct speed it immediately spins down. Usually I think there would be a click and then the heads would recalibrate. But there is no click and no head movement. I really would like to make an image of the drive. What are your thoughts? Are the heads sticking? Some kind of solenoid that is not releasing the heads? Not properly up to speed? (but it sounds like the speed is right) /Mattis

Nine track file marks, Burroughs

by drb＠msu.edu

Folks, I've now seen two Burroughs tapes where some of the expected file marks between labels and file data were apparently missing. I think a reasonable description of these is "Burroughs/Unisys B6x00 'Library/Maintenance' tapes with ANSI-69 labels" Reading drive is a Cipher GCR Cachetape with SCSI interface The one I read yesterday read in streaming mode and reported no read errors. I tried re-reading it today, and it read in start-stop mode, but still didn't have the missing file marks. (It also encountered a few errors, and eventually ended up sticking to the head, this time. Guess that bake cycle was a one-shot, which isn't a surprise.) This tape is a "Burroughs Series 7 / 100% Tested / 3200 FCI" 1200 foot reel written at 1600 BPI in 1986.

PDP-11/34 /04 power knob anyone?

by fritzm＠fritzm.org

Hi folks, I?m working on an 11/34 at the moment, with the programmer?s console, and it is missing its front panel power control knob. I think it is the same one used on the 11/04? Anybody have a spare in their parts stock that they?d be willing to part with? (I?m also missing the plastic half-panel for the front, but I do see those go by on eBay from time to time.) cheers, ?FritzM.

cc:Mail Router for NT

by tomas＠basun.net

Hi all, I'm using a HP 200LX to connect to a cc:Mail installation, with a null modem cable. It has worked better before, but now I don't seem to be able to connect at all. This is the output from the router, when trying to connect from the 200LX: | C:\CCMAIL\Router>C:\CCMAIL\Router\NTROUTER.EXE C:\CCDATA MODEM/PBX COM1 DIAGNOSTICS/F LOG/C:\CCMAIL\Router\ROUTER.LOG | cc:Mail NT ROUTER Version 6.10.00.4 | Copyright (c) 1986, 1997 by cc:Mail, Inc.

Here is the modem file: | [attributes] | MODELS=Null | NULL MODEM=1 | [commands] And another thing is that I only seem to be able to get a response at 1200 baud (the router default) by not specifying a speed when starting the router. If I add the speed to the command line (the first line above), any speed, (and the corresponding setting on the Palmtop) then there is no connection at all. It has worked better earlier. I managed to connect at 9600, but that was a different PC. I am not aware of having changed anything relevant on either PC or Palmtop. Any help appreciated. /Tomas

Rod Coleman's personal history of founding, building & running SAGE

by lproven＠gmail.com

This may be old news -- it was new to me, though. https://suddendisruption.blogspot.com/search/label/Booting%20Sage%20Computer I'm not really familiar with SAGE machines. They were not as well-known in the UK, I think, being upmarket from the Apple ][ and IBM PC, both of which were eye-wateringly expensive by UK standards of the time. Also, they were terminal-based things and even back then I was interested in boxes with graphics. :-) -- Liam Proven ?

Can someone check to see if a RQDX2 used the Western Digital chips to interface to MFM drives?

Keyboard storage, part 2

by aperry＠snowmoose.com

An update on keyboard storage, which I asked about here last month. I ordered some USPS Large Flat Rate Priority Mail "board game" boxes. This is a size not usually available at the post office and come 25 in a pack. They are a good size for mailing (and I am glad that I ordered them so I can use them for that), but I don't think they work for keyboard storage. They are so much larger than the keyboards that I am storing that lots of packing material is needed so they don't move around. Also, they are designed to be sealed and shipped, so there isn't a convenient way to open them once they have been closed. Next, I ordered the Uline keyboard boxes. I had to get 25 of them and they are not free ($2.70 per box plus tax and shipping). They can be open and closed. They are a much closer to the size of a keyboard (surprise, surprise!) so not much packing material needed, but they are slightly smaller than a Sun Type 5c (as well as Axil) keyboard and needed to modified for those two. No modification needed to store a Sun Type 4 or CompuAdd Sun-compatible keyboard in one. I haven't tried a Sun Type 6 yet. To anyone in the Seattle area that need keyboard boxes, I will probably have 10-15 of them once I get all of my keyboards packed. If you would like any, let me know. alan

I know multiple people that have signed victims up to mailing lists -- many of which were questionable content -- as an attack on said victims.

I've not seen anything in any provider's terms of service that say anything about what type of email they receive, save for exceedingly few categories; child porn and illegal activity among the short list. I have yet to see anybody state that sending an email to an invalid email address and (potentially) receiving a bounce is illegal. So, again, no grounds for Google to do anything.

Ouch, but 2 Perqs out.

by cz＠alembic.crystel.com

This was a long day. Went over to the house and started working on getting the Perqs out of the basement. I've been moving smaller stuff to make room and it was time. First up was a Perq1 chassis that just had the big disk drive in it, side and rear panels. I figured it was lightest and after taking off the sides and top was able to lift it and carry it up steps. Still heavy and bulky, but it made room and a path to get to the second one. The second one was a mess but a lot heavier: It still had the card cage in it and I was not going to be able to lift. So I figured out how to take the sides, top, front, back, and bottom (pounds are made of ounces) and then spottted the screws that hold the card cage and power supply in the box. Bless the people at perq, those two screws out and you can lift the cage out the side of the box. The card cage without cards (took them out to lighten) was heavy but I got it up the steps. Then with a herculean amount of effort I managed to carry the rest of the box up, followed by the sides, top, front, back, and bottom plates. There are still two more Perqs down there. They have heavier front plates (I was able to take them off) with real shielding. They were different designs, so they were not Perq1s and they are not the same as each other. Question: Are there any pictures of other types of Perqs? Unfortunately they are still buried under old Sun gear and a Vaxserver of some sort. So I'll have to think about those, but they will need to come apart as well. Question: Do the card cages and stuff come off the later Perqs as well? Also got two different types of keyboards that say Perq, and a monitor that looks like a big fat white Vetrex and says Three Rivers. Question: What does a Perq mouse look like? At least this stuff will not be junked. I'll take pictures and such tomorrow and throw a tarp over everything tonight because I'm too tired to get it out of the truck. I swore off high-mass hobbies for a reason....

Rod Coleman's personal history of founding, building & running SAGE

by boris＠summitclinic.com

Probably read about this machine in Byte back then but was programming PDP-11's. Was very disappointed in IBM PC as IMO was far inferior to PDP-11 which was was easier to interface to data acquisition hardware and had a much nicer instruction set. Ran into 68000 processor for first time in 1986 when my father bought a 512 K Mac and couldn't believe performance of this CPU compared to PDP-11 - 24 bit addressing! and inferior memory access to what Sage had. Also, found 68000 instruction set very similar to PDP-11 and had no trouble writing assembly code for it a few years later and also really liked Apple's debug switch which was best implementation of a debugging system I've thus far run into. Weird that Rod Coleman had 68000 instruction set associated with IBM 370 whereas to me it was very PDP-11 like and 24 bit addressing was a very nice feature (that was one similarity to IBM 360) Other interesting aspect to SAGE history was the influence of September 1966 issue of Scientific American computer issue on Rod Coleman and lots of other people I've talked to. Was so glad that had this issue to read in 1966 and spent most of my time in boring school classes designing logic circuits and then building them at home using discrete DTL logic with parts salvaged from surplus IBM boards. Thanks for the link as didn't realize 68000 was used for home systems before I ran into Mac. >This may be old news -- it was new to me, though. > >https://suddendisruption.blogspot.com/search/label/Booting%20Sage%20Computer > >I'm not really familiar with SAGE machines.

Winsystems SAT-V40

by doc＠vaxen.net

I know this is a long shot, but I'm asking anyhow. I'm looking for the Ops Manual for a Winsystems single-board system. Model: SAT-V40 P/N: 400-0186-000 The SAT-V41 model is essentially the same board, so I'd settle for docs for that. There are references (from 2012) to SAT-V41.PDF, so I know it at least *did* exist in digital form. If anyone in the US has the paper manual I would happily scan it, and pay postage both ways.

dp8340n IBM 3270 protocol transmitter encoder

by wh.sudbrink＠verizon.net

Hi, In cleaning up my lab and stores, I have discovered that I have a tube of 10 of these chips. I'm not quite sure what they are for or were used in (or even where I got them). Anyway, if they are, in fact, for managing 3270 mainframe terminal traffic, they're probably not of much use to me. I've also noticed that I'm getting very low in vintage 4000 series CMOS chips. Anybody want to trade? Bill S. -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

A PDF is available here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Manual.… http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Drawing… For those who object to PDF/A, here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Manual.tar http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Drawings.tar are TARs of the original TIFFs. The images aren't that great, I see; the original paper copies aren't too hot, IIRC. If anyone actually has a use for these (does anyone out there _actually have_ an MM11-F?), and there's a problem, let me know, and once I get my scanner running again, I can try and get better ones. I thought we were missing the MM11-E manual, so since the two are so similar (most of the boards are the same) I thought the MM11-F's would mostly fill the gap, but it appears it's there, prepended to the MM11-E prints. One thing this set has which might be useful is the backplane wirelist (the MM11-E's seems to be missing); given the commonality of most of the boards >from the MM11-E to the MM11-F, they're probably very similar.

terminals-wiki?

by dfnr2＠yahoo.com

The terminals wiki (https://terminals-wiki.org) seems to have been down for several months.? I hope the maintainer is OK. Does anyone know if this site is gone for good??? Is there a mirror anywhere?? The wayback machine has a few pages, but mostly serves to capture the look&feel. Dave

Seeking: TMS32010 Assembly Language Programmer's Guide (1983)

by pbirkel＠gmail.com

All; I seek a copy (hard or electronic) of the "TMS32010 Assembly Language Programmer's Guide" (1983). Paperback : 194 pages ISBN-10 : 0904047423 ISBN-13 : 978-0904047424 Publisher : Texas Instruments (December 1, 1983) Item Weight : 1.11 pounds Language: : English The "TMS32010 User's Guide" (1985) is readily available. Not so the (more important!) Programmer's Guide :-{. I recently obtained a TMS 32010 Evaluation Module (EVM). So I'm motivated to "learn something" about the details of programming the TMS 32010. My first hands-on foray into the (early) world of DSP :-}. I've searched all of the nooks-n-crannies of the web to no avail. All help in locating/obtaining a copy of this document will be greatly appreciated. I do have a copy of "Digital Signal Processing Using TMS32010" (Douglas L. Jones) on order as a stop-gap measure. Thank you, paul

PDP-11/70 backplane wire list

by derschjo＠gmail.com

Hey all -- Discovered a broken wirewrap wire on the 11/70 I'm slowly working on, it's on the last slot (44), and runs from BD2 to ??. White wire, part of a white/black twisted pair. I've been looking but haven't found a wire list for the backplane -- anyone have any leads, or, alternately, does anyone have ready access to an 11/70 backplane to trace where the wire from BD2 on slot 44 goes to? (Fortunately it looks like there's just the one wire on that pin, though there might be one "below" it on the pin that I can't quite see, rather cramped in there.) Thanks as always, Josh

Emails going to spam folder in gmail

by billdegnan＠gmail.com

Hi, I have noticed the same email addresses' messages routinely end up in the spam folder of gmail. It's no big deal for me to check my spam folder but it's an extra step and messages can be lost. For those of you who run your own mail servers please consider updating your DNS / authentication to match gmail standards. It's not about making a filter or marking messages as "not spam". It's about how the sending mail server communicates with gmail and the "newer" mail server gateway protocols, etc. so that it's not necessary to make a filter in the first place.' There are a lot of how-to's on the web, each mail server is different and there is no simple fix that applies to all. Bill

DEC part number system

vtserver for geezer '11s

by jacob.ritorto＠gmail.com

Hi, I modified vtserver to work on pdp11/34 and similar - the older machines that have the 000000 000000 000000 000000 @ odt prompt. I'm afraid I didn't do a very thorough job (hack night and just wanted to get it working) and in retrospect I wish I would've made a conditional argument to put it in this mode. Perhaps we should collaborate on adding this properly and adding other desirable features like compression for incoming "all zero" blocks when pulling images in from real hardware, etc. It's here if you'd like to use it: https://github.com/jritorto/vtserver You can run it with ./a.out -odt to facilitate its talking to the pdp at power-on and loading its initial boot sequence via odt in octal. You have to run the primary bootstrap with L 140000 and S <return> because I botched the parsing a bit in my rush to get things going. thx jake

Hey, I got a Perq_T2 image!!!

by cz＠alembic.crystel.com

Well, after waiting almost a month for the USPS to deliver a "Priority Mail 1 day" package from Dave I now have the MFM reader card. So I started working on these disks I rescued. First up was a ST506 (labelled "RD50" by DEC) and a pair of ST412's. Bad news: No drives spun up Good news: You can take the controller board off the drives and spin the spindles by hand. Better news: The spindles spun (clockwise, viewed from bottom) Best news: spinning while powering on got all three to spin up. So far I imaged the RD50 (possibly a Rainbow or a Pro/350) and one of the ST412's. It came up as a PERQ_T2 format and I have two dumps of the disk with only one bad sector reported. Anyone know what to do with this kind of image? I've powered down the drives and will store them till I can figure out how to make them run more quietly.... C

ISO: TI 980 (not 980A or 980B) Hardware docs

by derschjo＠gmail.com

Hey all -- A straight TI 980 (not one of the later 980A or 980B variants) appeared on my doorstep this afternoon. While well-shipped, the person I got it from decided to ship the boards and power supply separately from the chassis -- and unfortunately didn't document where anything goes. There is precious little information out there about the original 980 -- anyone sitting on any documentation? Anyone know someone who has one? (Anyone have any spare parts? The core memory boards & chassis are labeled well enough for me to see that I'm missing one of the "DA" boards...) Thanks, Josh

PDP-8 memory card on eBay?

Anyone recognize this card: https://www.ebay.com/itm/313323417718 I looked, and it doesn't seem to be any of those for a PDP-11. However, I see the DRAM array is 12x4 chips, which makes me think it might be for a PDP-8? Noel

FFS - PrismIQ Keyboards

by marvin＠west.net

I am starting to clean out stuff, and one of the things I don't need are these new PrismIQ IR keyboards. Apparently they were originally used with some multimedia stuff in the early 2000s. Because I am just trying to get rid of this stuff, I am only offering them in cases (boxes) of 10 keyboards. These use IR to connect to the device and have no other connectors. The keyboards are membrane type with the main chip inside being a Winbond W78le812-24. Power is supplied by four AA batteries. The cases (10 keyboards) are 20 pounds with a size of 18"x18"x10", and I am in Santa Barbara, CA. Unfortunately, I am unlikely to run out since I have some 40+ cases of them. I generally ship USPS Priority but can ship UPS if necessary. And again, they are free for the cost of shipping.

Toshiba "1-chip" things

There's a whole bunch of Toshiba "1-chip" QFPs I've run across. Does anyone know of datasheets, or what components (mask ROM, LCD, RAM, I/O, ...) they have? These are usually in cheapie toy systems, particularly VTech. Some allegedly have Z80-compatible cores in them. T7951 (I found this paired with a 2764 ROM) T7812 T7813 T7826 They all appear to be part of the same family. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Denial: it's not just a river in Egypt anymore, is it? -- "True Lies" ------

HP DDS3 DAT and DEC Tapes

by poc＠pocnet.net

Hello Folks, I?m having fun time to erase used DDS tapes for reuse. I?ve been collecting those over years. Recently, I discovered that with DEC brand tapes, the drive reports the cartridges to be write protected, eventhough the slider is closed which means, they?re supposed to be writable. I suspect there is a software write protect flag on them. Any thoughs, hints, advices how to unlock these tapes for overwrite? :wq! PoC

Compiling Fortran77 on the Pro: Where the heck are the library modules?

by cz＠alembic.crystel.com

So I'm working on compiling some programs on my Pro/380. 2.0 OS, Fortran77 compiler, Empire is the sample game. I got it to compile properly but when I try to link it the linker/tkb/pab fails with a bunch of undeclared references. Some of them are in the F77FCS.OLB library files on my pdp11/83 (M+ 4.6) like $CLOS, ISF$, $OSF, and $OPEN, but others like $EOLST, IOAB$, IOAI$, TT$EFN, and others are missing as well. Did DEC really jerk people around so badly by selling the FCS or RMS libraries as a separate installed product? I see some reference to RMSLIB.OLB but it's not on this system. Weird. CZ

DEC H765 line interference caps

by fritzm＠fritzm.org

Hi all, I?m just starting in on a PDP-11/34 for a friend (happy holidays!) I currently have the H765 power supply torn down for cleaning, inspection, and testing as a first step. While I have the transformer out on the bench, I?m wondering about the line interference supression caps on the ?CAP MOV? board attached to the transformer. These are CDE 220 VAC .1 MFD, across the line, in parallel with some metal oxide varistors. Drawing on collective experience here: would I be well advised to go ahead and swap these out for some modern X2 safety caps while I have the supply apart? Or are these in the ?oh those are rock solid; I wouldn?t touch em unless they were faulted? category? cheers! ?FritzM.

What happens on electro mechanical assemblies left in store for years is that ball bearing grease lube dries out and hardens, resulting in lumpy rotation and increased friction that can be detected by rotating the spindle by hand. RLxx series drives were very reliable typically, but the head movement assy is pretty cheap and cheerful. Converting spindle to linear movement, minimum parts count, dc brush brush motor, means that all the bits need to be smooth in operation, with no stiction anywhere in it's travel. I would take the motor out and if it can't be stripped to clean the bearings, use a dab of light clock oil to relube. Also, check the brushes and clean / polish the commutator. Any other ball bearings in the path, same process. DC brush motors can be a nightmare for that sort of precision positioning application... Chris

RL02 Tracking

by shadoooo＠gmail.com

> The ready lamp flashes not when the servo burst is >visible, but when the heads are just before it. > Why? Well, I probably set the gain too high on the read/write module. Hello, I'm sure you read the manual, however I add some explanation to be sure. The best head position is not where a servo track is at maximum amplitude (head is exactly centered to a servo track), but where you read two servo tracks with the same amplitude (so head is exactly between two servo tracks, in middle position). Comparative measurement of two servo tracks allow the servo control to understand the position of the head in respect to data track. If the best position for data track is not where servo have same amplitude probably the head is misaligned or the spring support of the head bent / deformed. To analyze head circuits you need a good oscilloscope, you should be able to see burst of servo tracks and data tracks too, with two channels you can understand if analog to digital threshold / pulses signal conversions do work as expected. Time ago I fixed an RL02 having a malfunctioning head amplifier circuit. The gain was too low. When I increased it rotating variable resistor, the circuit begun to ring (barely auto-oscillate), so was nearly unstable. Data and servo signals were corrupted, but this was visible only zooming on oscilloscope after careful trigger alignment. I don't remember exactly what I did, but some capacitors needed replacement, then I tuned head gain while loading a platter to the best position for operation, maybe slightly lower than manual recommendations. Then it worked perfectly. Andrea

Hopefully someone will have some.... The blasted one is on the left? side of the keyboard. Having a spare for the right side? probably not a bad idea too... We were missing keyboards? and got this like new one? gifted to us.? It was heartbreaking to see it damaged in shipping. We have a couple early 5150 umits with? expansion chassis.? Although only one of the? monster interconnect cables between the? pc and expansion chassis. Looking for posters lapel pins? and other display art to fill in? open areas... Any other ideas wekcome!

RL02 Tracking

by Aaron.Jackson＠nottingham.ac.uk

Hi everyone I've posted a few times over the years about RL02 drives and my difficulty getting them working (no luck so far!). I've spent the past few days working on one of them and have made some progress. The status currently is that the heads will load, and the ready lamp flashes as the heads wobble back and forth very slightly, trying to lock onto the outer servo guard band. Probing TP2 of the read/write module, I can see the S1 servo burst flash (roughly in time with the ready lamp). If I disconnect power to the servo motor, I can manually move the head onto the outer guard band (less than a mm away) and monitoring the position signal (TP15 on the drive logic module) shows this to be close to 0. So, I'm very confused. I've worked through chapter 3 multiple times... - voltage checks - all good - sector transducer output check - all good - sector pulse timing check - all good - read signal amplitude check and adjustment - all good - positioner radial alignment - required some tweeking but is good now - head alignment - looks good to me - spindle runout check - a little noisy but within spec - position signal gain check - looked ok - tachometer ac noise pickup check - this one didnt look so good Supposedly if the main drive motor is bad it will emit noise and cause the tachometer (just a coil of wire on the head carriage) to produce spikes. Mine does look quite noisy but I'm not sure what's causing it. I would expect that if it was picking up noise, I'd be able to detect this with my oscilloscope probe by putting it close to the motor, but I can't. Any ideas? Also, thanks to pjustice on irc who suggested checking the spindle grounding button. Mine is very worn out but I've been able to apply some pressure to it from the under side which reduces the resistance of the spindle to ground, from 400 ohm to 0 ohm. This didn't make the situation any better though. Still, the situation over all is much better now than it was last time I looked at the drive (over two years ago now I think). Previously the heads would attempt to load and then the fault lamp would come on immediately. At least now it's trying to lock onto a track. I have the same results with two cartridges (which is all I have!). If anyone has any ideas I'd love to hear them! Aaron (Sorry, as usual, about the footer appended by my university.)

Intermec 8625 printer

by nico＠farumdata.dk

Hi all, I'm hoping to get an answer here. The 8625 barcode printer has a prompting mode, switched on by activating the bottom switch in a bank of switches. The printer is then supposed to write a prompt, so you can start programming the label formats. I seem to remember that the printer expects a CTRL+H sequence to be reset/restarted, but nothing happens. Can any of you remember the settings for the terminal (I do know about 9600,7,1,even) ? I'm not sure on which terminal the printer expects to write to. VT100 ? ANSI? ? And how about flow control? Any help would be appreciated Regards Nico PS The printer is to be used for museum purposes, and as usual, the museum has no money to spend :-(

cc:Mail

by tomas＠basun.net

And one more thing, Am wondering about the possibility of setting up an interface between modern Unix email and the embedded client for cc:Mail on the HP 200LX. Various versions of cc:Mail are available from archive.org and vetusware.com, but the missing link seems to be the "client" type connection from the cc:Mail post office to the internet, i.e. for the PO machine to connect periodically and collect mail, rather than just acting as a server. Have not been able to find much technical information about cc:Mail. I did see a Lotus development kit for sale somwhere but seems to have lost the link. Does anybody here know anything about this? Are there any books or technical documents on cc:Mail available anywhere? /Tomas

Tape baking page by Wendy Carlos

by jwsmail＠jwsss.com

I ran across a reference to this on FB.? It appears to be from 2008, so may be well known or obsolete material. The other interesting info at the end of the article is the contact name and info about someone who restores or works on tape heads. Might be interesting to at least contact and ask if he's still around http://www.wendycarlos.com/bake%20a%20tape/baketape.html Contact John French, at JRF Magnetic Sciences (973-579-5773) for further details on magnetic tape head restoration and storage, and other related services and products. FB page with the info. https://www.facebook.com/ReelToReelTapeRecorders/photos/a.532104240183459/3… The fellow who does a lot of tape recorder (reel to reel) repair has a FB group worth dropping in on.? This is the link to a photo with a pretty bad Ampex head. thanks Jim

Last time I was at the Living Computer Museum, I talked to the guy restoring their 370 panel, who was using LEDs, because the original bulbs are all but unobtainable and do not lave a long service life. This is likely to be something you end up needing to approximate with modern components. Adam

WTD - Jupiter Ace plastic rivets

by classiccmp＠philpem.me.uk

Has anyone got a couple of the white plastic rivets which are used to hold the Jupiter Ace case together? They consist of a 4-point clawed rivet of about 5mm long, and a pin which pushes down the centre to open it out. I need five of them ideally - but even two or three would get the case buttoned up, if not perfectly. I've checked the local plastic supplier catalogues and haven't found anything which quite matches up. Cheers, -- Phil. philpem at philpem.me.uk https://www.philpem.me.uk/

found it: first speech synthesizer (at least, for S-100 systems)

by sieler＠allegro.com

Hi, Some years back, I was asking if anyone had information about the speech synthesizer developed for the Altair 8080 by Wirt Atmar of AICS (in New Mexico). No "hits". Most places on the web claimed the Computalker was first, given the date as 1976 or 1977. (Earlier speech synthesizes existed, but they were external boxes that one interfaced to, or were standalone (often with a large/weird keyboard).) Today, I stumbled over a fairly bad OCR of Byte magazine from August, 1976 at https://archive.org/stream/byte-magazine-1976-08/1976_08_BYTE_00-12_Speech_… It has two articles about speech synthesizers for S-100 bus systems. The first is by the Computalker people, who say: At the time this article goes to press, a synthesizer module incorporating several detail refinements and im- provements over the circuits of this article is being de- veloped by the author and associates. and A detailed user's guide will be supplied with the Computalker module Note the future tense! The second is by Wirt Atmar, whose product *was already shipping*. Near the end of his Byte article, Wirt lists currently available products: At the present time, two speech synthesizers are both commercially available and affordable by the hobbyist. One is the Votrax produced by: Vocal Interface Division Federal Screw Works 500 Stephenson Dr Troy Ml 48084 Price, approximately $2,000 Interfacing: Parallel or Serial (RS-232) The second is the Model 1000 manufactured by: Ai Cybernetic Systems PO Box 4691 University Park NM 88003 Price, $425 Wirt had told me (twenty years ago or so) that he thought his was the first for microcomputers (e.g., a user installed card, not an external box). Now, I'm sure ... but it was realllly close! Wirt demonstrated his product at the earlier MITS World Altair Computer Conven- tion, where it won first prize. He advertised it poorly/infrequently, since it was mostly a side business. And, that shows, since history doesn't remember it. Stan

You probably know this already, but if you're willing to pay, there are 'pack and ship' services who will show up at a location, take the stuff to be shipped, go pack it up, and ship it. I have used PakMail: http://www.pakmailcanada.com/ several times to retrieve things in this way (they shipped my PDP-11/45 from Ontario, although the seller did a lot of the packaging in that particular case), and have generally been happy with them. I don't see a London location, but maybe one of their other Ontario locations: http://www.pakmailcanada.com/pakmail-canada-locations is close enough to be useable? Noel

by sieler＠allegro.com

Hi, I'd like to apologize for referring to the OCR of the Byte article as a "fairly bad OCR". I was thinking of the garbled sections that may be the result of trying to OCR graphics. The vast majority of the text comes across clearly, and I don't want to insult whoever volunteered their time to do the OCR'ing ... I know how tedious it can be! I've been spoiled by OCR programs that produce their output as pdfs with searchable text, and should have remembered the results I get when I look at just their text! Stan

tty and video displays

by sieler＠allegro.com

Paul writes: > General overstrike requires a bitmap display, or some sort of persistent display. Although he carefully specified 'general overstrike', I'll still mention how the HP 2641A (an APL terminal) did it. When about to enter a newly received character into memory, the terminal checked if a non-blank was already in that spot ... if yes, it looked up the pair in an internal ROM table and replaced the existing character code with a new character code designed for APL\3000 (a code that, when received, would display as the appropriate overstrike). That meant that we couldn't use the terminal at Burroughs, because our APL had a few overstrikes that weren't in the table. Stan

Apple Investment

by c.murray.mccullough＠gmail.com

Apple went public Dec. 12, 1980 at $22.00/share over 40 years ago. Where has the time gone! A $1000 investment would be ~45 shares. Today that would be 5040 shares after 5 splits. Its price today is $121/share. That would be $609,840. Here in Canada that?s $939,153! Quite the nest egg. It has certainly paid quite handsomely to have invested in Classic Computers or in one company back then. Happy computing. Stay safe.

when was memory "above" the terminal screen invented?

by sieler＠allegro.com

Hi, First, apologies if I asked this years ago (I've searched my archives, no hits :) When was the concept of memory "above" the screen invented for terminals? I.e., previously displayed data that had scrolled up and off the screen ... but could be retrieved (usually by scrolling down). (Sometimes called "scrollback", or "offscreen memory".) (BTW, I'm talking about terminal-local memory, not a scrollback implemented by the computer to which the terminal is connected.) The HP 2640A, 1974, had (IIRC) several pages of memory available ... the user could scroll backwards and see what had been on the screen before it scrolled off (as long as it hadn't been lost by having too much subsequent output). I suspect the DEV VT100, 1978, had it, but I can't find definitive proof online (sure, I can find VT102 emulators that have scrollback, but reading an old VT102 manual doesn't make it clear that it has it.) thanks, Stan

Help needed identifying old MFM drives from the excavation

by cz＠alembic.crystel.com

As the excavation of Bob's junkpile continues I have finally hit the MFM layer. Specifically about 10 5.25 hard disks that look to be old style MFM drives. Vertex V150 Miniscribe 6085 ST 4038M Seagate Franklin telecom AT-40 Miniscribe 3650 HH Seagate ST4096 Priam ID45-H Rodime RO203E RD54 Real ST506 Pair of ST412's. Anyone recognize what kinds of systems may have used these? The RD54 is of course DEC, and I'm guessing the ST506 and 412's were from either a Rainbow or a Professional/350. But the rest are weird. Maybe Convergent miniframes? Probably not PC's as Bob had a lot of weird stuff. Thoughts? I'll see if I can get a mfm reader and suck data into files I can post for others to read/try/giggle at. But as there isn't much labelling I have no idea what is on them. Also did find Wordperfect and speller for what I think is Rainbow on 5.25 floppies. Let me know if you need a copy, or if a copy exists in archives (also two DEC disks for Learning the Rainbow or something like that) Chris

Perkins-Elmer 3600 and PETOS

by lproven＠gmail.com

Does anyone know anything much about this early desktop computer and its OS? Example: https://www.ebay.com/itm/Perkin-Elmer-3600-PETOS-Like-Microsoft-BASIC-Compu… Although it predated the PC, MS supplied the BASIC and apparently the CLI resembles early DOS. I ask because there is someone in the Free Pascal Compiler fora looking for help getting data off one -- they're still using it for data monitoring! https://forum.lazarus.freepascal.org/index.php/topic,52458.0.html -- Liam Proven ?

Fire-Sale PDP-11 update (and request for parts)

by derschjo＠gmail.com

Thought you folks might be interested in a quick update on my folly here. At the beginning of November I drove down to the bay area to pick up the two fire-damaged PDP-11 systems -- a PDP-11/70 and a PDP-11/45. (I also made a few other stops and got a few other items, but that's not what I'm here to talk about...) Over the past few weeks I've gone over the two systems and my assessment is that the 11/70, while completely filthy, is completely restorable. The fire/heat damaged the front panel enough to discolor the plexi and start melting a few switches (http://yahozna.dyndns.org/scratch/1170/1170.jpg) but that's the extent of the damage. My only fear is that the fingers on the backplanes might possibly have some corrosion here and there, but I've started going through and cleaning the boards and the backplane slots and so far I haven't run into anything that looks troubling. The 11/45 is considerably further gone. It took a serious amount of heat, enough for the pig iron frame for the front panel to start melting ( http://yahozna.dyndns.org/scratch/1170/1145.jpg). The front panel is completely destroyed, as is the wiring harness for the power distribution. But... the metal of the chassis and the power supplies seems to have protected the boards and the backplane. There are no melted or even discolored wire-wrap wires on the backplane, and the boards look fine. As an experiment I took the non-11/45-specific boards out of the backplane (a Plessey memory board, an RL11 controller, and an M9301 bootstrap terminator -- this one was right up front where things were the hottest and the handles had started to melt) and tested them in my PDP-11/40. They all work fine. So I think that, maybe, with a LOT of effort, the 11/45 could live again. I'm tackling the 11/70 first (Al kindly sold me a new front panel for a very reasonable price so it already looks 100% better) and once I'm done with that I hope to move on to the 11/45. In the meantime I'm hoping to keep my eyes peeled for parts for the /45. I found a seller on eBay with "restored" H7420a power supplies for $68, with free shipping so I grabbed a pair. I realize this is unlikely, but I was curious if anyone has 1) any parts of the 11/45 power wiring harness, or 2) (really unlikely) an 11/45 front panel in any condition. Well, any condition better than "melted into slag," I suppose. I can build my own wiring harness, but if I can save myself the trouble, that'd be nice. - Josh

Problems with FORT and ALGOL in TSS/8

by kej＠kyrafre.com

Hi everyone, The Nostalgic Computing Center <http://www.nostalgiccomputing.org/> has a virtual PDP-8 running TSS/8 <http://www.nostalgiccomputing.org:8080/aterm.html?m=pdp8&t=PDP-8&r=24&c=80> in its collection. We use the SIMH PDP-8e emulator to support the machine, and we recently updated the machine to run the TSS/8 distribution created by LCM+L, found here on GitHub <https://github.com/livingcomputermuseum/cpus-pdp8>. The LCM+L distribution is slightly different from other TSS/8 distributions available on the web in that it provides some additional goodies such as ALGOL and LISP. The NCC demonstrates how various classic computers worked by providing automated scripts that interact with the machines in the collection. For example, to demonstrate each of the programming languages supported by a machine, scripts are provided to create, compile, and run a simple Fibonacci sequence generator. We've done this for the TSS/8 system, but the scripts aren't working for FORTRAN or ALGOL, and we're wondering if anyone on this list might know why. Specifically, in the case of FORTRAN, the compiler exits with an error code 6204. This occurs even when trying to compile trivial "hello world" programs, and it appears to occur in all other TSS/8 distributions we've tried as well (i.e., this particular problem is not unique to the LCM+L distribution). We haven't found error code 6204 specifically documented in the TSS/8 user/admin manuals, but the manuals do document other error codes in the 62xx range. Documented error codes in the 62xx range appear to reflect file I/O errors, so we're wondering if perhaps one of the files supporting the FORTRAN compiler is corrupt in all of these distributions. For example, here is a transcription of a simple session demonstrating the problem: .R EDIT INPUT: OUTPUT:FTEST A WRITE(1,10) 10 FORMAT(5HHELLO,/) END E ^BS .R FORT INPUT:FTEST OUTPUT: 6204^BS . We tried enabling the floating point processor to see if lack of FPP might cause FORT to abort, but enabling the FPP did not solve the problem. The SIMH configuration file for the machine currently looks like: set throttle 800K set df disabled set rf disabled set rk enabled set dt enabled att rk0 tss8_rk_lcm.dsk set cpu 32k attach ttix 4000 load boot.bin run 200 Note that BASIC, FOCAL, and LISP all seem to run very nicely on the machine. The problem we're experiencing with ALGOL appears to be a glaring compiler bug, but the compiler was distributed widely through DECUS, and it is difficult to imagine that it would have been released with an obvious bug, so we are wondering if perhaps we're not interpreting the user manual <http://svn.so-much-stuff.com/svn/trunk/pdp8/src/decus/8-213/decus-8-213.pdf> correctly. Here is a transcription of a session that exhibits the problem: .R EDIT INPUT: OUTPUT:ATEST A 'BEGIN' 'INTEGER' I; I := 1; WRITE(1, I); SKIP 'END' $ E ^BS .R ALGOL INPUT:ATEST OUTPUT: *TOO MANY UNDEFINED [UEXPRESSION* ^BS . The compiler seems to be complaining that the simple assignment statement on line 3 of the program is somehow incorrect. If we change the statement to "I := 1 + 0;", the error message goes away, and the program runs, but it prints "0" instead of the expected "1". Also, if we change the program to: 'BEGIN' 'INTEGER' I; 'FOR' I := 1 'STEP' 1 'UNTIL' 10 'DO' 'BEGIN' WRITE(1, I); SKIP 'END' 'END' $ it compiles successfully and it prints what is expected, the numbers 1 through 10. Does anyone have experience with the ALGOL/8 compiler? If so, does this behavior make sense, and can you let us know what we're doing wrong? Note that the same ALGOL60 program compiles and runs as expected on the CDC mainframes and the TOPS-20 system at the NCC. thanks! Kevin

Atari ST diskettes

by van.snyder＠sbcglobal.net

I found a box of 45 Atari ST diskettes in my basement, from my 1980's 520 ST (or maybe my brother's 1040 ST). I don't have a floppy drive, so I can't tell whether they're readable. Some are originals, for example for 1St Word, the word processor, and Regent Base, a relational database program. Others are copies. If you send a PDF of a USPS media rate shipping label, 4"x5"x6", 3lb, they're yours. Coordinate with me so you don't send a label after somebody else has already sent one. Van Snyder

Taking apart a Perq

by cz＠alembic.crystel.com

So I'm getting into the "I can see the box" layers in the excavation project, and I have a question: I've got a box that may be a Perq, and a printer that may be a Perq printer. The printer looks like an old Laserjet I, and the box is metal, 3ish feet tall, and has what looks like a 10 inch hard disk inside. Problem is I won't be able to get it up the steps. (Where have I heard that before). So how much can one take a Perq box apart to make it as light as possible? Is it simple to get the drive out? Power supply in there somewhere? How about the card cage? Pics at: https://i.imgur.com/ohuohvC.jpg https://i.imgur.com/81him0F.jpg

Looking for Hazeltine 2000 keyboard

by dfnr2＠yahoo.com

Hello, I just picked up a Hazeltine 2000c? terminal without the keyboard.? If anybody might happen to have (or know of) a spare Hazeltine 2000 keyboard, I would be very interested.? I realize it's a long shot. The keyboard is a standard ASCII keyboard, with several extra function keys and lights, so I'm pretty sure I can whip up a replacement, but the whole point is to recapture the original look and feel.? Back in the '70s, Memphis State (Now U of M) had a few of these terminals, and a great many Hazeltine 1500 terminals.? I've been hunting for a Hazeltine 2000 for ages.? It would be awesome to have one up and running. Dave

Boot Roms for MRV11-C

by dj.taylor4＠comcast.net

The boot roms for the MXV11-B multifunction board can be used in the MRV11-D general purpose ROM q-bus board.? Neat if you want to put together a small system. I have a MRV11-C board and it differs from the MRV11-D board primarily in the ROM sockets, 24 pin on the MRV11-C and 28 pin on the MRV11-D so I can't use the MXV11-B ROM's directly. Can the MXV11-B ROM set be adapted for the MRV11-C board?? If not, what can you use as a bootstrap ROM set on the MRV11-C? Doug

Radio Shack 8MB hard disk for Model II

by spacewar＠gmail.com

I had occasion to look at the service manual for the Radio Shack 26-4150 8MB hard disk which was used with the Model II (and potentially could be used on 12, 16, 16B or 6000). Note that this drive is not compatible with the Model I, 3, or 4, and the cable wiring between the computer and the controller (inside the drive box) is entirely different than what was used on the later 5, 12, 15, 35, and 70 MB drives. The Model II host adapter for the 8MB drive thus is only useful with the 8MB drive, and vice versa. There were later Model II host adapters that could be used with the 12, 15, 35, and 70 MB drives, which were also useful on the Model I, 3, and 4. Anyhow, I discovered that according to the documentation, the 8 bit data bus between the host interface and controller uses 8T26 bidirectional buffers at each end, which are rated to sink up to 24 mA, but the schematics show that Radio Shack put 220/330 ohm terminators on the data bus lines at BOTH ends of the cable! That requires the 8T26 to sink as much as 55 mA, which means that its logic zero output voltage is likely to exceed its normal rating. At the very least, this will result in reduced noise immunity. I don't have an 8MB host interface or drive in hand to confirm, but the photos I've found online do show the resistor networks on both ends. The controller (inside the drive box) is a modified version of a WD1000, configured for use with the 8-inch SA1004 drive, which operates at 4.34 Mbps, NOT 5.00 Mbps like 5 1/4" drives. Aside from that, it has a different host pinout than a normal WD1000 (or than the later Tandy controllers), and has extra circuitry for dealing with write protection. Electrically, the host interface is otherwise the same as the WD1000. Normally the data bus for the WD1000 would only be single-terminated at the controller end. That is in fact what Radio Shack did on all of the later host adapters.

VMS on x86-64/ARM/RISC-V? - was Re: Microvax 3100 VMS 7.3 password reset

by camiel.vanderhoeven＠vmssoftware.com

On 11/14/20, 1:49 AM, "cctech on behalf of Adam Thornton via cctech" <cctech-bounces at classiccmp.org on behalf of cctech at classiccmp.org> wrote: > I mean obviously the NEXT thing to do is start bugging VSI for ARM support?given that the OS runs on VAX, Alpha, Itanic, and x86_64, how much really crucial and hard-to-port assembly can be left in it??and given the way datacenters are trending, it might not even be a commercially stupid move. I want to run VMS on my phone (or my next Mac). Doesn?t everyone? Hi Adam, Possible architectures beyond x86 we're keeping an eye on are ARM and RISC-V, but they'll need to start doing a lot better in the datacenter before it'll be worth our while. So far, ARM in the datacenter hasn't taken off the way many predicted it would. One thing I'm better at than crystal ball gazing though, is I can give you an idea of how much hard-to-port assembly is left, since I wrote most of the x86 assembly code in it :-) With the port to x86, we made a conscious effort to minimize the amount of code written in assembly; so at this point, it's pretty much limited to code where (a) we can't use the stack, or we need to manipulate the stack pointer in a non-standard way; (b) we need to use a special instruction that we don't have a compiler builtin for (these are mostly cases where an instruction is only used in one place); and (c) code that needs to mix calling standards - i.e. the code shims necessary to interact with the UEFI firmeware. Category (a) is obviously the more interesting one, and that includes things like code that is responsible for switching between VMS' four modes (kernel, executive, supervisor, and user mode), and context switching for the schedulers (OS scheduler, kernel process scheduler, and POSIX threads scheduler). The OS scheduler is a good example of our effort to eliminate assembly code. On VAX, Alpha, and Itanium, the scheduler loop and the idle loop (which performs maintenance tasks such as dirty page zeroing) were written in assembly, and re-written with each port. For x86, I rewrote these in C, using small assembly helper routines only in the critical parts where it couldn't be avoided. In total, there are 30 modules that were written in x86-64 assembly. I'd classify 10 of those are trivial, 16 as average, and 4 as complicated and difficult. The complicated and difficult category contains code responsible for dispatching system services, handling interrupts and exceptions, delivering ASTs. As much design and work was involved in those assembly modules though, a whole lot of x86-specific work was done for the MACRO-32 compiler. MACRO-32 originated as the VAX assembler, and while it is a compiler on other architectures, it is still much like an assembler, and specific translations from the VAX instruction set to the target architecture need to be made. The MACRO-32 compiler talks to the LLVM code generator backend at a lower, more instruction-centric level than the compilers for higher languages, and this work is very x86-64 specific. Given that about 1/3 of the OS is written in MACRO-32, we won't get rid of MACRO-32 code in the OS any time soon. (The other 2/3rds are written in BLISS and C) Also, in the C, Bliss, and MACRO-32 code, lots of conditionalizations are made on architecture. Certain things are done differently on Alpha than they are on Itanium, and on x86 we sometimes do things the way we did them on Alpha, sometimes the way we did them on Itanium, and sometimes we need to come up with an x86-specific way. So, the port to x86 has made a future port to ARM or RISC-V easier; particularly by moving to the LLVM code generator backend, and by figuring out how to run a four-mode OS on a two-mode architecture without sacrificing the benefits of running in four modes; but it has by no means made it trivial.

NEC NEAX IVS2 PBX with NEAXMAIL AD-8 - hard drive clone, issues

by keith＠saracom.com

Hi Liam, As stated in my OP, I was using Windows 10 and USB adapters. I used Rufus, Active Disk Image, and Macrium Reflect programs to copy it an image file and then back to the CF. They are supposed to create exact images of the drives but I think they do not. Of course it could be something with my CF to USB adapter. As far as errors, as stated in my OP, "Since the voicemail card is running headless, I can't see the error messages." The only way I know of a successful boot, is one LED turns green and then I can call in to the VoiceMail card. I am going to try a Linux machine and DD next. > ------------------------------ > > Message: 5 > Date: Fri, 27 Nov 2020 16:12:39 +0100 > From: Liam Proven <lproven at gmail.com> > To: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk at classiccmp.org> > Subject: Re: NEC NEAX IVS2 PBX with NEAXMAIL AD-8 - hard drive clone > issues > Message-ID: > <CAMTenCFACtaGvYBp3cowxhWjestSyBmeyUx=8RXjJ8er3O__-w at mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" > > On Fri, 27 Nov 2020 at 01:32, keith--- via cctalk <cctalk at classiccmp.org> wrote: > >> I have tried to copy it to an industrial CF >> card but no luck.

NEC NEAX IVS2 PBX with NEAXMAIL AD-8 - hard drive clone, issues

by syseng＠gfsys.co.uk

The way I would do that is to use a Linux / unix machine and one of the cheap ebay usb to ide adapters, then use dd to image the whole drive to a file. That should copy block, including the boot block and partition table. Use the reverse process to image the file back to another drive... Chris

NEC NEAX IVS2 PBX with NEAXMAIL AD-8 - hard drive clone issues

by keith＠saracom.com

Hi Everyone, Not a classic computer but has a 386 embedded in it for the voice mail. I rescued it from work. We had it rung for 20 years straight. The voice mail (AD-8) is basically a 386 running MS-DOS 6.22. So my concern is the hard drive. It is the original 2.5 inch IDE IBM Travelstar 6 GB drive. It has bee running for 20 years except for a handful of extended power outages. Hence while it is working now, I don't have too much hope for the future. The PBX had its on battery backup and also was always connected to a UPS. I have tried to copy it to an industrial CF card but no luck. I have used Rufus, Active Disk Image, and Macrium Reflect. I don't have my older PCs up and running at the moment, hence I have been trying with a Window's 10 machine and USB adapters to no avail. Since the voicemail card is running headless, I can't see the error messages. There is a serial port but but I have figured out the settings yet. Any suggestions? Do I need to get a DOS machine running to do this? And yes, I really don't need the voicemail working, nor do I need a PBX in my house but why not?

LCD screen repair

by trash80＠internode.on.net

Hi folks - be grateful for a little advice please. Some time I rescued an Apple Power Mac G4 (it's a beautiful machine, not that I'm a big Mac person, and I can't believe someone was going to toss it) - powers up OK but looks like it just needs a new battery as its not holding date and time. Anyway the other day I was cleaning up in my collection facility and dropped the monitor - I wasn't quick enough to save it from hitting a metal object just under the bench and as chance would have it of course this happened screen side. Its put a gouge in the surface of the screen - link to photos below. http://koken.advancedimaging.com.au/index.php?/albums/apple-screen/ Now I believe it is possibly repairable but the are many kits and methods out the all claiming some success. I figure I'm only going to get one shot at this so would appreciate any advice from anyone who may have effected such a repair before. Thank you. Kevin Parker <https://t.sidekickopen76.com/s1t/o/5/f18dQhb0S7n28cFFdQW752kH81jkhdLW1_k-L- 1qZM43W3s0v_y2M0f8BF4c2NfHml5Hf6Bq4h603?si=8000000004908274&pi=2139d449-dcd9 -4daf-91a4-c2defc817fd5>

FS: Tek scope, HP LA, and Electronic components!

by mechanic_2＠charter.net

Hello all, I have probably developed cancer. I can't get in for treatment. I have enough lumps in my body that it probably wouldn't make a difference. So more than likely I am dying. I am asking for everyone's help. I am selling off all of my processions and simplifying my life before I die. I don't want to see this stuff end up in the landfill. Please help out a dying old man? I have a Tektronix 465B Scope with four probes for sale. A HP 16700A LA with 5 16555D LA cards and all of the cables. There is a 16701B Expansion box and the interconnect cable. There is an external SCSI drive box with a CD rom and a ST318417N drive in it. There are a bunch of micro probes for the LA. A monitor, keyboard, mouse, manuals, and CDs. I also have a very large collection of electronic components in over 40 storage cabinets. There are also a lot of books on electronics. I am asking $250 plus the shipping on the scope. This shipping won't be cheap. $500 plus shipping for the LA. Again shipping will be very expensive. It will take five boxes to ship the LA. I will deliver the scope and/or LA to any where in the lower 48 for the cost of shipping. $500 for the components, cabinets, and books. Shipping is not possible. So it it have to be local pick up. Bring a truck and trailer. PP F&F, Cashiers Check, or Postal Money Order. Please contact me off list. GOD Bless and Thanks, rich! Happy Thanksgiving!

Hi Chris, There's a few options in this regard, in increasing degrees of "realness" (and cost!) depending on how you define it. 1) The PiDP-8 by Oscar Vermeulen - Raspberry Pi based 8/i replica running SIMH in a miniaturised case. https://obsolescence.wixsite.com/obsolescence/pidp-8 2) The SBC6120 - Originally by Spare Time Gizmos, but now re-released by the RetroBrew Computers community. This is a 6120 based PDP-8/e replica, with optional front panel. (the panel doesn't appear to be made "officially" anymore, as the design files are missing, but a Russian company appears to have copied it. (I have the Russian version but have yet to assemble it.) https://www.retrobrewcomputers.org/doku.php?id=boards:sbc:sbc6120-rbc-editi… http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm https://chipkin.ru/product/pechatnye-platy-dec-pdp-8-e/ 3) The LD12 / LD20 by Franklin Prosser and David E. Winkel - This is a TTL based clone of a PDP-8/i, originally devised as part of an exercise in the book "The Art of Digital Design An Introduction to Top Down Design" in the early 80s. A few people on vcfed.org have built their own based on these designs, and daver2 has made a run of PCBs (wirewrapped!) http://www.vcfed.org/forum/showthread.php?74125 4) Vince Slyngstad of so-much-stuff.com has scanned many PDP-8 boards and re-created them in Eagle CAD software. I know he's been working on re-creating the 8/e CPU recently but AFAIK it's not finished yet. There are however many OMNIBUS peripheral cards, and a board that combines 32KW of battery backed RAM with a boot ROM. Roland Huisman has also re-created the RX8E floppy controller, and has made an RX02 emulator to go with it, so if you lack an RX01/2 drive you can still have something to boot off. Kyle Owen has also created a neat bit of software that allows you to use a spare serial port and a *NIX system to simulate an RK05. So with all this, it should in theory be possible to build your own 8/e class system soon enough if you can find all the parts for it. http://so-much-stuff.com/pdp8/cad/boards.php https://github.com/Roland-Huisman https://github.com/drovak/os8diskserver Regards, -Tom mosst at sdf.org SDF Public Access UNIX System - https://sdf.org

Osborne 1 keyboard repair - success!

by ccth6600＠gmail.com

I have managed to completely disassemble the bad Osborne 1 keyboard - remove all key mechanisms (body, plunger, main spring and actuator spring), remove the 3 layer membrane from the aluminium backing board and separate all three membrane layers (bottom, spacer and top) - all without damaging or losing any bits. I then carefully cleaned off all adhesive and other sticky gunk from all layers using various solvents including water, isopropyl alcohol and white spirit. The silver tracks remained undamaged as confirmed with a multimeter. I then carefully reassembled the 3 layers, inserted and super-glued the keyboard mechanisms in batches, testing after each batch. I did not use any glue to reattach the 3 membrane layers so they are held together only by the keyboard mechanisms with their prongs protruding through the layers into the aluminium backing plate to which the prongs are super-glued. I sealed the edges around the membrane using Kapton tape to provide protection from dust etc. The tape also attaches the membrane edges to the aluminium backing plate. All keys except the "Alpha Lock" key work perfectly. It appears that I have damaged the address line 7 on the bottom membrane. I can live without "Alpha Lock" so I did not pull everything apart again to fix this un-important key. The conclusion is that membrane keyboards can be fixed if your life depends on it. It is absolutely uneconomic though. I worked about 30 - 40 hours on the keyboard alone. Working Osborne 1s sell for between US$100 and US$300 on Ebay. Regards Tom Hunter

Crypto Ancienne: TLS for the Internet of Old Things

If you have an older pre-C99 system, I've backported a TLS 1.2 library to gcc versions as early as 2.5 as long as it has 64-bit ints (long long, usually) and stdarg.h. https://github.com/classilla/cryanc As a test, with a suitably agreeable (or confusable) browser, here are various period browsers visiting modern HTTPS sites through carl, the included demonstration application which can also act as a TLS proxy.

evil thing to ask but I need keystroke logger

by boris＠summitclinic.com

If it's a windoze system, modified a bare-bones keylogger about 10 years ago which records all keystrokes (can get time of key_press, key_release) and also monitors all mouse clicks as well as title of window clicked on. Can also record every mouse event which takes up a LOT of disk space. Just hooks keyboard and mouse events and works even on hospital systems which are fairly locked down. Written in VB6 and also wrote a program to either look at keyboard/mouse events over time or to dump text typed in. Has saved lots of work for me as windoze has a bad habit of crashing when I'm 20 minutes into writing a note and can get all keystrokes that were saved to disk during this time. Initially written to find out how much time I spent IFOK. Also has a stealth mode where keylogger window hidden and can be brought up with a key sequence and then need a password to stop it. Not very stealthy as can be easily terminated through ProcessExplorer. Could always use Wireshark to capture all packets exchanged while they're on computer. >I have kids that after corona are in lockdown, so they are on >computers all the time. >Supposed to be doing schoolwork, but no, feedback from the school is negative. > >Can I trap some traffic from these PC's and what software would you recommend? > >Randy

Seagate Elite "reverse surging" noise

by jules.richardson99＠gmail.com

I picked up a couple of 9GB Seagate Elite SCSI disks the other day (model 410800N, 1995-vintage but 5.25" FH units). Both drives spin up, both pass r/w tests successfully. On one unit, the spindle motor sound is constant. On the other, however, it makes a sound that I can best describe as "reverse surging", where every 5 seconds or thereabouts there's a very brief lowering in tone before the "normal" sound resumes. Anyone familiar with the Elite range know if "some of them just do that", or if it's likely to be some form of fault (which may only get worse)? I've never encountered a disk which does this before; my ear's not detecting any kind of speed increase prior to the decrease (and I don't know if that's what's really going on or not), but that's what my brain wants to think is happening. However, if the speed really was fluctuating to the point that I could hear it then I'm surprised that I'm not getting read/write problems. cheers Jules

TU58 dumps. Mostly VAX 11/750 AND 11/730 diags and console tapes.

by mattislind＠gmail.com

I dumped almost 50 TU58 tapes. They were given to me by an ex DEC FS engineer. Most of them are various 11/750 diagnostics. The tapes or not the official DEC TU58 tapes but home brewed tapes used in FS so there might not be an exact match to existing lists of official tapes. But they might be useful anyhow. I have seen diags for CI 750, DW750, RH750, DT07, Various Ethernet, UDA50, TK50, DZ32, DMF32, DH11 and some more standard 11/750 MIC, DPM tests and instruction tests. Then there were some 11/730 tapes. Console and two diag tapes. I collected everything in a google-drive-folder https://drive.google.com/drive/folders/1CkcXVJS9aJDwD4ihdj27QYcgkm7gEdrQ?us… This folder also contains some older dumps I have done. Both DECtape and DECtape II. All dumps are aggregated into a document trying to give a hint on what the dump contains. Beware that some dumps failed to read correctly and are just partial. But it should hopefully be clear from the file size. https://docs.google.com/document/d/1vD8erJM-HitSd4kRXt6_Rzl403HDoprr08EY69u… /Mattis

Floppy pressure pad replacement?

by deramp5113＠yahoo.com

I?ve got some adhesive backed industrial felt that I punch with a leather punch. I?ve replaced many of those pads on 8? and 5.25? drives and the felt pad works well. Shoot me an email and I can send you a few pads if you need. Mike

Looking for Console MUX cable for HP E45

by rp＠servium.ch

I recently acquired a HP 9000 E45. Unfortunately, it came without the console MUX panel and cable. I was lucky to find an ADP II (5062-3054) in my "pile of useful stuff", but sadly, the 78pin to DB9 cable is missing. The part number of the cable is 5060-3074 though there might be others that work (5062-3074 is mentioned a few times in the HP forums, but not in the manual so I'm not 100% certain it's the right cable). Does anyone have a spare cable or an ADP or DDP with the cable they would let go for a reasonable price? Or have one and could tell me which 9 out of those 78 pins go where on the DB9 connector? thanks Rico

Microvax 3100 VMS 7.3 password reset

by athornton＠gmail.com

I for one was thrilled to see that there will be x86_64 hobbyist licenses for VMS. I have an emulated VAX on a Raspberry Pi (I don?t know if my 11/730 works, but I doubt it?it?s nowhere near a 220V power supply and it?s not been much of a priority, and I have a VAXStation 3100 that doesn?t pass POST even with a freshly-burned ROM) running OpenVMS 7.3, and a real AlphaServer 800 running 8.4. I mean obviously the NEXT thing to do is start bugging VSI for ARM support?given that the OS runs on VAX, Alpha, Itanic, and x86_64, how much really crucial and hard-to-port assembly can be left in it??and given the way datacenters are trending, it might not even be a commercially stupid move. I want to run VMS on my phone (or my next Mac). Doesn?t everyone? Adam

Next project: 11/24. Does it need memory?

by jnc＠mercury.lcs.mit.edu

> From: Jay Jaeger >> 2--M7134 KT24 Memory map > M7891 UNIBUS Memory (256K, I think, presumably addressed for 0). If that's all the memory you have, the KT24 isn't really doing anything (well, monitoring power; holding boot PROM's; etc). Is your MS11-L configured to be EUB memory, then? If no KT24 is plugged in, the CPU detects that there isn't one there, and permanently, statically maps the UNIBUS straight across to the bottom 256KB of EUB space. (Presumably a low-cost option for the /24.) Although the 'straight across' mapping only applies to UNIBUS->EUB cycles, not EUB->UNIBUS cycles, such as those from the CPU; but the TM says [pg 2-31 in the 003 version] that if E124-S6 is OFF, "the lower 18 bits of every address go to the UNIBUS", which implies that when OFF, UNIBUS memory appears at 0 in the CPU's address space. So it should work as UNIBUS memory, with E124-S6 OFF; it would be interesting to verify that. The TM also says (pg. 2-40) "systems with UNIBUS memory ... require changes to be made to the mapping jumpers [on the KT24]". > Let me know if you want me to go thru the process of > .. > 2) Pull the boards and document What kind of box is your -11/24 in, a BA11-A, or BA11-L? If the latter, I'd be really grateful for some closeups of the interior, so I can put mine back together, and do some of these experiments. (Yes, yes, I know I should have taken pictures before I took it apart; I was just starting, and was going by how we used to do things, back before there were digital cameras.) I could probably work it out by staring hard, and thinking harder, along with the prints, but photos would be a lot easier! :-) If it's a BA11-A, I'm still trying to get an image of the special power adapter used to turn the bus bar of the BA11-A into the 6/15 pin Mate-N-Lok connectors used by the -11/24 backplane.
