anyone have/can make an openvms (vax) ISO?

by dgahling＠hotmail.com

I just moved, and all my stuff is still packed away, including all my openvms CDs, which kinda sucks because I sorta need one right now. in the interim I could get away with an ISO, if someone has one. Any version would do, so if there's someone on the list that has one or could make one, it'd be much appreciated. As I said, I own the originals, bought from montagar, just not sure which box it's hiding in... Dan. _________________________________________________________________

I'd suggest Tiny Basic as a starting point. If you need less than that how about a machine level monitor like ODT? Generally that's where I've started for any machine, some form of keyboard monitor. It's also a starting point for IO that can be used by more sophisticated software or a language. Allison > >

Source for MMJ cables.

by tiggerlasv＠aim.com

I don't have a source for MMJ cables, but I do have a US/Domestic source for MMP's (the offset modular connectors). . . http://www.gruber.com/GruberInd/pg.asp?FeatureID=38 They are .14 / each for flat cable, and .41 / each for round cable. Last I checked, they don't ship internationally. There are two different styles of DecConnect cables; both inverted, and not inverted.?? The only difference of course, is that one connector is flipped on one end. When used with genuine DEC adapters, one?style worked for printers (DCE), and the other style worked with terminals (DTE). Back in the early 90's, our office used uVax 2000's, connected to VT220's. along with various printers, connected using DEC MMJ <> DB25 adapters. You couldn't simply swap the DecConnect cables because of the inverted MMP's on some of the cables. All of our cabling and adapters were unmodified DEC products. If you're really in a pinch, you can always pop the connector off of one end of the cable, and re-crimp it by hand. It's a bit cumbersome, but you can use a thumb-tack to lift the gold contacts out of the connector, and then use a small flat-blade screwdriver to push them back in. Just be careful not to stab yourself in the process.? ;-) As info. . . T

Source for MMJ cables

by tshoppa＠wmata.com

Andrew writes: > A little while ago I bought a "new" 10ft MMJ cable from That Website. > Today I came to use it and discovered it was a crossover cable. All MMJ cables are supposed to be crossover cables. If you are using DB-9 or DB-25 adapters on the ends of the MMJ's, then they have to be appropriate to the wiring for the device. Examples: Rdy Out TX+ TX- RX- RX+ Rdy In Adaptor Gender 1 2 3 4 5 6 Use with: -------------------------------------------------------------------------- H8575-A F 20 2 7 7 3 6&8 VTxxx terminal H8571-C M 6 3 7 7 2 20 Digital printer H8571-D M 6 3 7 7 2 20 Modem H8571-E M 20 2 7 7 3 6&8 Female terminal or LaserWriter -------------------------------------------------------------------------- If you've got the wrong adapter, you may be able to open it up and swap around pins 2&3, 6&20. Some are shells you can open up and use the DB-pin-remover tools to swap things around, others are molded solid and you can't take them apart so easily. MMJ was a nice concept for serial cables.

Certainly they were > common in the 1960s, but were they standard in the 1950s? An interesting question. I would have said they were common in the late 60s but not in the early 60s. None of the 1301s (built 1962-65) I have seen were on raised floors, maybe because 700 square feet of raised flooring would have been expensive, but I suppose not compared to 247,000 pounds for the computer itself. When I first started programming them in 1969, I think all the ones I visited were on raised floors, had 'tacky mats' and air conditioning, which often blew out of the floor. On the other hand, when I went to work for a company which made computers (in 1974) and which used them extensively for software development, there were no raised floors, no tacky mats and only one of the computer rooms had air conditioning because it was the only one to used exchangeable hard disks, the rest used paper tape or cartridge mag tape or one inch analogue tape for audio data which was used as test input to sonar processing computers. Just my experience, maybe not typical, and in the UK. Roger Holmes

trying to use AT&T VFD display module

by jeffj＠panix.com

I salvaged several AT&T/Lucent/Avaya D401A Digital Display Modules, apparently from a Definity phone system. The label says D401A AT&T 89338 series 1 The module has 8 touch-buttons and LEDS and an Itron DC 405A2 VFD (one line of 40 characters, each char a 5x7 matrix) I'd like to use the entire module since it has a microcontroller and power supply, but I have no clue as to the interface. Any help would be appreciated, starting with pinout. I really need the internal programming document with all the commands :-( I'm trying to strike a balance between researching the device to use completely "as is" vs. salvaging entire assemblies vs. salvaging just bare parts. Sometimes it's easier to just redesign it and salvage as many subassemblies as possible than taking the time to reverse engineer the entire gadget :-( Googling around found: "This digital display module ... adds a large easy to read 40 character display to the top of the 7405D or 7434D voice terminals. AT&T/Lucent systems compatible with this module are Definity G1, G2, G3, ECS and ..." Thanks in advance -- Jeffrey Jonas jeffj-at-panix-dot-com

Anyone have docs on the 82971A EPROM/ROM module for the HP Integral PC? Anyone have one of these that they have in use for some purpose? I rediscovered one of these while cleaning up some piles of stuff. I'm curious if there is anything interesting that can be done with one of these.

ETH Lilith Emulator available

by julianskidmore＠yahoo.com

Hi Jos, Well done! At last I've been able to run EmuLith on my 17" G5 iMac under Panther. No idea how it compares with the original performance, but after recompiling with O2 it runs fairly quickly. Here's my comments: 1. Well, first, a big congrats!!!! 2. Why is it white on black when all the photos show black on white? 3. I used Sara to write HelloWorld.MOD, but Couldn't compile it (Disk5.IMG). It complains about missing InOut (though InOut.OBJ is there). Compiler runs though :-D 4. 768x592 seems to be partially implemented, it'd be nice to fully implement it; though I'll try and run it on my external display. (I get around my inadequate display by pressing RETURN ;-) ) I presume the microcode is different for the smaller display, but the OS and libraries are almost the same, since I guess the 4:3 Liliths were still used when the 7:9 ones appeared. 5. Lara wouldn't run, problem with DiskWindows. Your user-base is increasing in leaps and bounds :-D -cheers from julz @P

WTD: MPF-I/88 documentation

by James.Paul＠colibrys.com

Tony, Do you still have the documentation that goes with the MPF-I/88 computer trainer? If so, I know you said you didn't have a scanner, but how about taking the manuals a Kinko's or Office Depot / Office Max, and see if they can copy it. I would be willing to pay for a copy of this documentation. Please advise. Thanks and Regards, Jim

Scrapping NCR 3430's and Wyse 286 Boards

by martinm＠allwest.net

I'm scrapping two NCR / ATT 3430 servers (MCA bus). If anyone wants the whole machines, they are free for pickup in Evanston, Wyoming (82930) or parts are available for shipping cost (and beer money, if the taker wants to be generous). Both servers are Pentium 60's with two processor boards per box. I also have some boards for a Wyse 286 (I think). There are two processor boards, one disk controller board, one video card and one serial / parallel board. Free for shipping. Email me directly. My address is "martinm" at the domain "allwest.net".

Reading an MFM hard drive with a floppy disc analyser

by classiccmp＠philpem.me.uk

I've just been thinking about the problem of imaging/copying MFM hard discs... I've run the numbers, and this seems right to me, but I'd appreciate a sanity check. Let's say you have an ST-412 drive you want to read. You've also got a Catweasel or something like it, that has somehow had an extra bunch of I/O lines added to it (to control the head select lines, etc. on the HDD). An ST-412 rotates at 3600 RPM. That's (3600/60)=60 revolutions per second, or 1/60 = 16.66(recurring) milliseconds per revolution. The drive's data rate is 5 megabits per second, but could be lower (or indeed higher). But the spec says 5Mbps, and for the sake of argument I'm going to stick with that... (5Mbps/1000) = 5Kbits per millisecond. 5Kbits * 16.667 = 83.35 kilobits per track, absolute maximum. A Catweasel records the data from a disc by measuring the time between flux transitions. If we assume every data bit on the disc is a "1" (MFM coding "01") then you'd need to store at most 90,000 timing samples per disc track. So hypothetically, if your "Catweasel or something like it" had 128Ksamples worth of buffer RAM, and enough I/O lines to drive the HDD, you could read an MFM hard drive track-by-track and copy it onto another drive of the same type? Do my calculations look right? With 304 cylinders and 4 heads, that works out to 304 * 4 * 83.35 = 101353.6 Kbits, which does seem awfully low to me... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Better IMHO to repair the old rare keyboards than replace with something new but 'incorrect' for a given system, though a new keyboard can be a temporary solution until the old one is fixed. You basically take keyboard apart, remove all the conductive discs but don't throw them away, scrape the remains of the foam off the bottom of the key plungers (can use goo-gone to help with this too), punch new foam disks from 3m grey mounting foam, clean off the old conductive paper discs (also can use goo-gone to help here), carefully apply discs to foam, and stick new foam+old discs back onto each key plunger. Apparently you should use a qtip with a small bit of goo-gone around the edge of each new foam disc to prevent the top and bottom from sticking together and 'pillowing' the foam disc. It may be easier to first stick the conductive discs to the foam and use the disc as a guide for punching the foam, that way it will always be exactly 'on register'. The trouble is you need to buy a punch to punch the foam into discs of the same (or slightly narrower) size as the shiny conductive paper discs are (or have it shave a small bit off the edges off of the conductive discs, if they're a tiny bit smaller it shouldn't hurt anything I'd think). I have not done this yet, and am not sure where to buy an appropriate punch (art supply store didn't have it). If any of the aluminized-paper contact discs are 'beyond repair', I have NO idea how to replace those. Aluminum foil MIGHT work, but it doesn't sound like a good solution because its TOO conductive, I think. I have 4 keyboards that need fixing in this way: one keytronic kb3270pc (1986 firmware) four victor 9000 US-type keyboards (manufactured by keytronic) Fortunately (unlike the old digital group keyboard keytronic made with its completely insane #-shaped contact pads) I believe all 4 keyboards use the same diameter paper contact circles and foam, so I should only need one punch. -- Jonathan Gevaryahu jgevaryahu(@t)hotmail(d0t)com jzg22(@t)drexel(d0t)edu

What should an old lady do with an Osborne?

by RichA＠vulcan.com

I work with much bigger, and usually much older, things than luggable personal computers, so when a lady in my museology certificate class came up to me to ask whether we would be interested in her friend's Osborne, I had to say "No." She then asked me if I knew where her friend could donate such a system; I told her I had no real idea, and that I would ask around. So I'm asking the assembled multitudes: What should an old lady do with an Osborne? Honestly, my only thought is to put it on That Auction Site(TM) and see what market forces say, but that's too scary for a non-computer person, I would think.

jCquard -- make modern punched cards

by frustum＠pacbell.net

http://www.outstandingelephant.com/jcquard/ (quote) jCquard is a generally useless JavaScript library that you will probably (hopefully?) never need to use ? unless you are the nostalgic type, you like to roll with the old-schoolers, or you are convinced that the end is near and soon all we?ll have left are stacks of punch cards with which to rebuild the entirety of our culture. (endquote) The program produces a image of a punched card given an input string. The biggest problem that I can see is the text printed along the top is a crisp CRT font. They should have digitized the character set from a real punched card.

Such powerful boxes are to do intensive calculations on >servers running real operating systems, or to just do gaming using the >aberrant wannabe operating system. Working (reliably and comfortably, >as Tony and many of us want) and Windowing are not compatible. :-) I thought I would chime in at this point. In the Mid 80's, my College had a perfectly functional PDP11 system. It used provided support for RSTS-E, was well appreciated, reliable, and the workhorse for all of the computing programs throughout the school. The machine was in the computer room, its front panel was out in the open, and nobody did anything bad to it. the most malicious piece of software that was run was a program that I wrote that output human readable character patterns sideways on paper tape. In about 1988 (or so), the powers that be decided to replace it with a Prime computer. All of a sudden, the student body was not very happy about the replacement. The Unix like operating system didn't look like RSTS-E, the terminals were HORRIBLE (They took away our beloved VT52's), the editor EMACS, was not very friendly at all. All of our code was GONE! Agreed that the machine was Bigger (tm), Faster (tm), More Functional (tm), than the PDP we had, but the user experience was woeful. Needles to say, that the student body decided that they had to find ways to break the thing. Malicious software was created, the machine was regularly halted from the front panel, and reliability went through the floor. Eventually, they made a physical cage for the machine to reside in that even the longest broom handle couldn't manipulate the front panel switches !! At least the reboots stopped. What am I trying to say here... You can get faster hardware, but if it is operated in a HOSTILE environment, then you will have a bad time. To a point, I agree with the snapshot concept of not installing arbitrary software, and leaving an environment in a working state. If you are patient, you *can* get a windows machine to operate reliably. But the *last* thing you do is to install yet another random upgrade for yet another piece of software without careful testing. The windows concept simply does not translate to the classic computer environment. There is no way that I can impact the operating system of my CP/M system by simply running a terminal program (unless I specifically perform a download). Likewise, there is no concept of downloading a device driver that hasn't been tested on any of my PDP11 machines. The machine base was simply too small and too well controlled. The modern environment is radically different, there are hundreds of manufacturers of cards and motherboards, and other hardware, and millions of equipment combinations possible. And, there is the dreaded concept of BACKWARDS COMPATABILITY. Woe is me, as a manufacturer, I have to support arcane cards in systems where they simply may not work.... (Could somebody please explain why having an ISA bus slot in a PCI system was a good idea!) In summary - you can have a 'powerful beast' and have it work. you just have to adopt a 'professional' attitude to running it, and not download arbitrary software willy nilly. How do you do that when the modern browsers are designed to download and execute arbitrary code??? By not doing that! Just my 0.02 worth. Doug

Open source, stand alone, ASCII terminal project

by bob＠jfcl.com

I and a couple of other people thought it would be fun to build our own stand alone video terminal. The prototype is a 3x5" PCB that is completely self contained - all you need to connect is a VGA monitor, a PS/2 keyboard, 12V power, and a RS-232 connection to a host computer of your choice. The idea is that you could easily stick one inside the case of an old VGA monitor, add a keyboard, and then have an ASCII terminal. No PC required :-) I did the hardware design and PC boards, and James Markevitch did the lion's share of the firmware, with help from David Betz, Ethan Dicks and Dave McGuire. The firmware is all open source, GPL licensed, and is managed as a Source Forge project. The microprocessors (yes, there are two used) are 8051 cores and the firmware for both is written mostly in C using the SDCC compiler. SDCC and the other development tools we're using are all FREE, mostly open source, and the primary MCU can be in system programmed using a regular PC and an ordinary serial connection. No expensive development tools or special hardware programmers are needed. Enough firmware finished now to be a functional VT220 clone - it can run EDT and vi already - but there's still lots to be done. We'd like to find a couple more people to join the development team and help us finish off version 1. In particular, some of the major things that still need doing include - Fonts (a VT220 has a surprisingly large number of DEC specific fonts) Serial EEPROM drivers for saving setup and configuration data Documentation, users manual and web pages (on SourceForge) and of course testing Some of the things we're thinking about working on after V1 is finished - Emulating other ASCII terminals (ADM, TeleVideo, Wyse, maybe more) Adding graphics (Tek 4006/4010/4014 emulation, ReGIS, maybe more) If you're interested, I have two more of the prototype PC boards that I can sell. And if you really want, you can always wire wrap your own without a PC board - the schematics are available as part of the project documentation. email me and let me know if you are interested in working on the project. Right now I'd prefer that the PC boards go to people who have the time to actually help out with the project in the short term, so if so if you'd just like to have one of the terminals but don't have time to help then please stand by. There'll be another announcement when we have one ready for release. Bob

UK DEC Meeting in North West, Autumn 2009 - expression of interest please

by mark＠wickensonline.co.uk

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Well, I've been banding this idea around to a few fellow DECheads in the UK, and thought it was about time I moved on to stage 2. I am thinking about organising a meeting for people interested in the line of computers created by Digital Equipment Corporation. It is likely that the meeting will be autumn next year, and would be run over a Saturday and Sunday in Windermere, Cumbria, UK. This is in the very early stages of planning, and I'm initially looking to get an idea of numbers who might be interested. This is to ensure that I can organise the event without loss. In terms of numbers I would be looking for between 10 and 20 people to exhibit computers, and then another up to maybe 50 people as non-exhibitors. I'm sure we could get some interesting speakers involved. Cost is likely to be in the order of GBP 10 for the two days, although we can discuss the option of providing catering if there is interest. I would be looking for firm commitment to buy a ticket say 3 months in advance. So in the first instance, could anyone interested email me at: mark at wickensonline dot co dot uk. By emailing you agree for me to keep your email address on file so that I can inform you of any progress. Please feel free to make suggestions either on this mailing list or direct by email. Kind regards, Mark Wickens -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkk3wecACgkQR0vMj/mgdjaeAQCgoiTAk9YqL9PJIbiXFpJxpJgg 8skAoMSCQ0cgLUB6xMiFXxgpSnMmw30J =wa/6 -----END PGP SIGNATURE-----

Making an RT-11 TU58 Image

by toby＠coreware.co.uk

Hi, I've just managed to get a TU58 emulator compiled up and running under Linux and confirmed its working by booting Will Kranz's XXDP images (http://www.fpns.net/willy/pdp11/tu58-emu.htm) I'd now like to get an RT-11 TU58 image so I can run a boot into a real operating system on my disk-less -11s. Whats the best way to go about making a suitable image? I have a working RT11 v5 setup under SIMH. Is it possible to make a suitable image via this? One thought is to make a RX01 boot image and but with a TU58 boot block and then use this on the emulator.

You can build an RX image, or as hinted at above, you can create an entire RL02-sized image and use it with the TU58 driver (DD). It turns out that RT11's DD driver only cares about size of the media when it *writes*, but it can read any properly initialized media of any size. As you suggest, using SIMH, mount up a blank 'disk' of whatever variety you want (RX01 would be fine, but a little small for working with RT11 easily, I'd suggest an RL01 or RL02), and initialize it, copy over the files you want, and just as you say, do a COPY/BOOT with the TU58 driver (DD), such as: .COPY/BOOT:DD DL0:RT11SJ.SYS DL0: to put the TU58 driver in the boot block of a RL0x. At this point you'll need to physically cable your Linux box running the TU58 emulator and the PDP-11 with a simple null-modem cable. When you fire up the PDP-11 hardware, you'll have to enter the TU58 bootstrap (which Will gives in his emulator documentation). At that point you should be home free. It won't be fast, but it will certainly function fine. If you do create a non-TU58-sized virtual disk image, you'll want to again refer to Will's docs where he gives you a patch to the DD.SYS driver, setting the number of blocks allowed. This will allow you to read and write to a larger (than standard TU58) disk image. Good luck! - Jared

[Sorta/Probably OT] Gmail "Terminal" theme

by eric940＠gmail.com

For those Gmail users out there: Click "Settings" / "Themes" and choose the _Terminal_ theme. It gives you a (kind of) cool terminal looking theme within a web browser when logged in to you Gmail. I know: many purists out there use Pine, Elm, and the like... but there are a few that need to use browsers when reading email for whatever reason (myself included) on occasion. I just enjoy seeing the green font/black background scenario on my monitor whenever possible :-) OK, back to Topic related issues.

Arcade games

by philip＠axeside.co.uk

Just curious... There's a shop in Coalville, I'm not sure what it sells (maybe it sells games consoles; maybe it's an amusement arcade; maybe both). In the window this weekend were two machines that caught my eye: an original Space Invaders machine from 1978, priced at 895 pounds; and a pinball machine from 1979 (branded "Gottlieb") for an almost-as-unreasonable 495 pounds. (I think at current exchange rates that's about $1300 and $700 US) As I was walking home, failing to hum the Space Invaders song, I wondered what sort of an active market is there for such machines? The prices looked high enough that they must be aiming at serious collectors, or possibly innkeepers who want to create a retro-seventies atmosphere. So do people here know about the classic arcade game market? Are my neighbours of a couple of blocks away being overoptimistic with their prices? Philip. PS What I remember from the period was the many, many attempts to write Invaders-style games in BASIC on the PET and other home computers. And my friend Matthew, after we'd borrowed a Sinclair ZX81 and experimented for a week or two, shutting himself away and writing a quite good one for that machine in machine code - I helped with the BASIC shell that built the initial screen display. And wiring a phone earpiece to the PET user port to hear the sound effects on the Commodore invaders program. And so on... PPS has anyone preserved the Space Invaders song? I sincerely hope not.

Tragedy in our hobby: Jay West ....

by evan＠snarc.net

Hi all, Every few months Jay gets busy at work and disappears. That's been a regular cycle for several years, so personally I don't get too worried. However, I did start to wonder recently because he's been gone for longer than usual. Personally I last spoke with him at VCF West in 2007. Christian wrote >>> where is Jay? I've tried to contact him via email but haven't got any response yet. His last post to this list was at the end of May. Ethan aded >>> I'm guessing, though, that nobody has heard from Jay himself in quite some time now. Sridhard noted >>> I hope he's ok. So I decided to pick up the phone today even though Jay usually doesn't answer his phone, preferring email. Alas, I'm very sorry to report this tragic news to the list .... .... "Rumors of my death are greatly exaggerated." Jay had a very sturdy laugh (for a supposed cadaver) when I mentioned sending an email with the "tragedy" subject line. :-) He's just busy at work. As usual. - Evan

Plug-n-Play for vintage machines?

by brain＠jbrain.com

I'm considering designing some cartridges for the CBM line of computers, but I'd prefer to skip masses of jumper blocks and move to a soft-config option. I know, some of you love jumpers, but for carts, it's more important to offer flexible options so that the SW can reconfigure carts on load. I have no issues with adding a small uC to a cart to do the heavy lifting, but I'm struggling with a way to communicate with the uC from the CBM machine. In the past, people have added config registers to a IO space, but that introduces its own issues (how to hide the registers, what about conflicts, etc.) Ideally, I'd like to use an approach that: * works via the existing address/chip select/data lines of the cart ports * will handle multiple equipped carts on the same port (port expanders) * uses as few lines as possible to communicate with the host machine * will not affect non-equipped cartridges * not require major amount of horsepower from the uC side. I thought using and SPI/I2C-like approach using an address line or two and a data line to communicate with the cartridges. But, that approach requires something to "unlock" the config system and lock it again. Any alternative ideas? Is there any prior work in this area I should re-use? -- Jim Brain, Brain Innovations (X) brain at jbrain.com Dabbling in WWW, Embedded Systems, Old CBM computers, and Good Times!

Omnibus core memory compatibility?

by hachti＠hachti.de

Hi folks, I have the following stuff: G104 X/Y drivers G227 Sense/Inhibit G619A 4K core stack The 4K stack is broken and lost forever. But I have a spare G646C "4K or 8" Stack sitting around. I *think* it has 8K. Does anyone know if I could use that stack with the rest of the package, using only 4K of the memory? Does anyone have schematics for the 8K core system? In my documentation I have only information about the 4K system. On Doug Jones' module list, there are mentioned 4K and 8K sense/inhibit boards. And there are mentioned X/Y driver boards, without 4K or 8K written on them. I would like to know how DEC expanded the core. Doubling X or Y lines would be the easiest. But why should that result in different sense/inhibit circuitry? The sense/inhibit connections look quite similar on both of my stacks... Or does everything change? Thanks for clarification :-) And if someone has a spare 4K stack, please contact me! The same for 8K sense/inhibit and X/Y drivers. Best wishes, Philipp :-)

The drift of a knowledge-based societ to a gadget-value-based society.

by aek＠bitsavers.org

> I think the clever society is getting burned down as we know it Clever is now content, not the tool. Computers and other electronic devices, and the communications infrastructure are a given. The invention now is what can be done with this hardware, which is now generally too complicated to build yourself, and as a result has just moved up a level. Even software tools are now pretty much taken for granted. You just program to fill in holes in the already existing tool space. This shift pretty much defines what I see coming out of people fresh out of college now, and most things dot-com and forward.

Problems with VAX 11/750 console

by fireflyst＠earthlink.net

Hi all, I'm trying again to get my 11/750 running. It turns on, power lights are green, machine comes up halted with the dim error light as it should. THe problem I am having is, I get no console...I get an echo back of the characters I type, but nothing else. Doing a BREAK command or a Ctrl-P does nothing. The closest thing I can find to this problem is in the 11/50 FAQ, found here: http://www.vaxarchive.org/hw/750faq.html Here is what the FAQ states: "Help! My machine isn't listening to the console! Symptoms: machine starts up normally and prints the successful microverify double percent and the console prompt, but ignores console input. This may be because the RS232 line receiver on the console port has given up the ghost. I've had to replace the one on mine twice. Note that it isn't a good idea to leave the console terminal switched on if the machine is switched off -- the line receiver chip doesn't like this and tends to fail eventually. To replace the line receiver: a) Locate and remove the L0004 UBI module. b) Hold the UBI component-side up with the edge connectors down the RHS. c) Locate E53, a 1489, at the right-hand side of the board, near the top of the second edge connector. This is the only 1489 on the board. d) Replace E53. I strongly recommend using a socket for the replacement. " Now, this does not sound similar to my problem. I have indeed verified that all the jumpers on the backplane are in the right place, and so are the connectors. The jumper is set to 300 baud, and that is indeed the only setting I get a clean echo back without garbage on. Any suggestions? I'm out of ideas at this point. Julian

Cat manuals

by dwight＠svdc-imap00.amd.com

Hi Al I forgot to mention that the Technical manual seems to be missing page 93. This is the same as I have. It might be interesting to make a trip to the Stanford library and see if they have this page in their copy. I'm not sure when I'd be able to do that. Looking at the manual, there doesn't seem to be any context missing but a single page section could have been missed. For non-students and non-graduates, one is limited to 3 sessions a year at the special collections section of the library. One still has to reserve the document a few days in advance. If you are interested in researching other documents from Jef's collection or anything else in there vast collection, I can point you to their information. I wonder if the CHM might already have some special arrangement with the Standford library on shared information for research purposes. Jeff left quite a bit of stuff related to early Apple days.

Making an RT-11 TU58 Image

Definitely want to help!!! I'm always looking out for this kind of thing. My 11/750[1] came with a handful of TU58 carts and I've still got the TU58 drive fixture that I cobbled up to my PDP-11 to make images. I'd be more than happy to image what you have. I've located a few (maybe 10 or so) 11/750 diag cart images in the past, but I'm still looking for that "full set" of standard 11/750 diag tapes. If you have them (or, even if not) I'm game for imaging what you've got. I'm in Utah, so there's probably some shipping involved, but I'd probably be able to cover charges both ways to help with getting these imaged. How big is that "large box" you've got? ;-) - Jared [1] After a year I'm still struggling with bringing my 11/750's 5V power supply back to life.

Hard disk material

by roger.holmes＠microspot.co.uk

> I have no idea about the material, but I can tell you about one application method you may not have considered. I have mentioned it here before but maybe you have joined the list recently. Similar drums were made by ICT/ICL from 1962 to 1965 for the 1300 series, and probably for the 1200 series drum based computers in the 50s. They too had fixed heads with set screw adjustment, which was carried out by monitoring the pressure of compressed air blown through a venturi in each head while moving an Allen screw. The 1300 drums were 12000 48bit word capacity, driven by a 3/4 horsepower motor geared up to 5240rpm at the drum spindle for lower access times. After many experiments they found they could not beat the human hand applying a magnetisable compound like a potter making a pot. Sounds very low tech but apparently it works, and I have drums which have not been touched since manufacture and they still work 46 years on. Of course for you, low tech could be a bonus as it means low cost. Maybe your local educational establishment has a skilled potter who could do a great job for a reasonable price, or just for interest. > The drum is quite low density, and does not have air bearing heads. > The head heights are actually adjustable with a bunch of set screws. > The heads themselves are also pretty big.

one more qume dt8 related question

by jzg22＠drexel.edu

The Qume DT8 I have has only the HL line cut on the programmable shunt block at 1E. This doesn't match any configuration shown in the usage or service manual. Also, it has the SS trace (between U3E and U3D) cut. This trace is not explained anywhere in the user or service manual except that it is shown to exist. The schematic at the end of the latest rev manual at bitsavers shows that it has something to do with whether head 0 or head 1 is selected (or perhaps loaded) in regards to the READY and INDEX signals on the shugart interface. Does anyone know exactly what it is supposed to do? I got lost in all the logic. Thanks, -- Jonathan Gevaryahu jgevaryahu(@t)hotmail(d0t)com jzg22(@t)drexel(d0t)edu

My system uses an 8bit TTL Keytronics Capacitive Sense keyboard. It was operational for about an hour and then it quit. It turns out that the keyboard uses little sponge pads to hold the capacitive disks and they have biodegraded into dust. So I went looking for an old 8b TTL replacement keyboard. So far no luck. I also looked for a black box solution that would take an AT or PS/2 keyboard and convert it to a parallel port output. So far no luck. So let me turn to the experts and ask for advice and suggestions. Please advise Robo -----REPLY----- Hi! I feel your pain on trying to obtain parallel ASCII keyboards. They are not easy to find and sometimes when you do they are not compatible or require extensive modifications to work. My suggestion is to use a PIC (16F628) to implement a simple serial to parallel converter. I did this to with a PIC to convert a spare broken KayPro II keyboard (300 bps serial) to 8 bit parallel with strobe for use with a Vector Graphic FlashWriter II parallel keyboard interface. The same could be done with an XT or AT (PS/2) keyboard although a bit more complex. The software source code examples available on the internet. One of the N8VEM builders (James) just did a project to add a AT (PS/2) keyboard to the N8VEM SBC so that might be a good place to start for a source code example. Thanks and have a nice day!

HP13264 Data Link Interface

by ard＠p850ug1.demon.co.uk

Does anyone know anything about the HP13264 Data Link Interface, or the network (?) it was connected to? It's mentioned in passing in the documentation for the HP98268 comms card, and I've just bought one. Let me describe ehat I've discovered so far. Physically it's a plastic box of the same design as used for many other HP intefaces (like the 82164 HPIL-RS232 interface). 2 cables come out of it. One ends in a 50 pin Microribbon plug, which is the HP 'RS232' port connector. The other is a figure-of-8 cable ending in a strange 6-contact plug that I'll describe more later. On top are 2 LEDs marked 'Link' and 'Transmit'. Inside there's a PCB containg a few standard chips, some passives, and 2 optoisolators (one single, one dual). It draws power -- +5V, +12V, -12V from the HP RS232 port (power lines were provided on this connector). The only RS232 signals used are TxD, RxD and RTTS (which is strapped to CTS). The last is used as a transmit enable. There's an isolated PSU on the PCB, driven by a 555 astable. It provides 6.7V to the circuity on the 'network side' of the optoisolators. The TxD and RTS signals are bufferd to TTL levels (1489 chip), and fed into the dual optoisolator. The RTS signal also drives the 'Transmit' LED. On the other side of the optoisolators, they go to 4011 NAND gates, which drive 4 transitors as a full-H driver. These drive the netowrk cable (there are 3 siganls on this cable -- Sh (Shield) which is connected to the ground of the isolated PSU, and +, - which are driven by this full-H circuit). The network cable is monitoed by a 311 comparator. Its output drives the remaining optoisolator, the output of which is buffered to RS232 levels (1488) and then drives the RxD signal to the computer. This optoisolator also drives a circuit that controls the 'Link' LED, such that a '1' on the network cable flashes said LED. If the network cable is in a steady state (no matter what state), the LED is off. Note that the receiver is always enabled, a computer monitors its own trasmission. Presumably that's used for collision detection. There are 2 3-way terminal blocks on the PCB for the cable to the network connector. Corresponding terminals are linked by PCB tracks. The cable is a figure-of-8 thing with each part being a screend (twisted?) pair. Obviously the inners go to the '+' and '-' terminals on the PCB. This cable ends in a connector that's a bit like an overgrown microribbon connector without the outer hosuing, but with only 6 contacts. There's a picture of the interface and this connector on the Austrralian HP museum site. The 'business end' looks a bit like this : - | | -==--==--==-- | | | -==--==--==-- | | | - Where == is a contact area (6 in all) That would be looking at the face of the socket, which must have a 'T' shapped cutout in it to allow the plug to go in. I assume there are6 contact springs in the socekt to connect otther cotnact areas on the plug. Now, corresponding cotacts on the 2 sides of the plug are connected together. But not directly inside the plug, but rather from one side of the plug, up one of thr pairs of the figure-of-8 cable, then via PCB tracks to the corresponding wire in the other pair, back down the cable, and to the contact on the other side of the plug. This means that the figure of 8 cable won't appears as a 'stub' on the main cable. I would guess that the socket has contacts that touch when the plug is removed, thus completing the connections I've just mentioend. This looks a bit likea French teleohone socket, but I'd heard that this was normally an 8 pin device, withe the other contacts on the 'head of the T (right hand part of my diagram). Whether I could use such a socket andwhether it would need modification I don't know. I also don't know if such sockets nroammly short corresponding contacts on the 2 sides if no plug is connected (as I mentioned in the last paragraph, this would be desireable here). So, does anyone know anything about this device? What was it used for? What was it used with? What was the socket? Protocol? Any manuals/docs o the web (a google search found nothing useful)? Thanks in advance for any help -tony

IBM DemiDiskette

by aek＠bitsavers.org

If anyone is curious about what an IBM 4" floppy drive looks like, I just uploaded a picture and the patent for it to http://bitsavers.org/pdf/ibm/floppy http://www.weblog.com/comments.aspx?blogid=30290&postid=71765 4-inch floppy diskettes In the mid-80s, IBM developed a 4-inch floppy diskette, the Demidiskette. This program was driven by aggressive cost goals, but missed the pulse of the industry. The prospective users, both inside and outside IBM, preferred standardization to what by release time were small cost reductions, and were unwilling to retool packaging, interface chips and applications for a proprietary design. The product never appeared in the light of day, and IBM wrote off several hundred million dollars of development and manufacturing facility. CHM appears to have one http://www.computerhistory.org/collections/accession/X1140.93 Mismarked at 5 1/4" (grrrr..) And a disk http://www.computerhistory.org/collections/accession/102667528

I think I used to have a Pioneer LDV1000 with a proprietory parallel interface using a small Centronix-style connector. I scrapped it because the power supply was blown, and I got an RS232 interfaced one that plays CAV and CLV with barcode scanner, etc. I just touched the adapter box in my storage unit that converted the parallel interface to RS232 and I have the manuals ... somewhere :-(

I have a "ChipQuik" kit of some flux and a slug of something like Wood's Metal, presumably the trick you are talking about. I have yet to use it (it's just a free sample). The documentation seems straightorward, though. Does anyone on the list know where to get moderate quantities of Wood's or Field's Metal at reasonable cost? By moderate, I'm thinking of a small number of pounds (kgs). I don't have an immediate use for it, but in the next year or two, I'm considering building a RepRap or a Fab at Home and one of the things on the horizon is printing circuits with low-temp metal on top of printed plastic substrates. I'd like to see how much the metal is going to cost before I go down that route. -ethan

70's view of Army Radar Installation (with computer gear)

by cclist＠sydex.com

I just ran across this page: http://cryptome.info/0001/loc/loc-images.htm It seems that LOC has been rather ham-handedly censoring some of its online historical content. Of particular interest is a shot of computer peripherals (printers, card readers, tape drives), all of which appear to be vintage CDC gear (military versions of the 512 printer, 65x tapes, 405 card readers...). I don't know what the mainframe behind this was, nor does it seem to be shown. Anyone have any idea? BTW, the TIFF images are 20MB each and very high quality--enough so that I could read the CRT displays and the notice of "Volley Ball" and "Hayride" on the bulletin board. Cheers, Chuck

cctech moderator on holidays

by ethan.dicks＠gmail.com

Hi, All, Lawrence Wilkinson <lawrence at ljw.me.uk>, one of the classiccmp moderators, asked me to post a quick note to the list that he is travelling around NZ and can't check the moderator queues as often as he does when he's home. This means that moderated messages will be delayed more than usual, and that if you are a member of cctalk _or_ cctech and post from an address you did not subscribe from, it will take him longer to spot those messages and release them. Unmoderated postings to cctalk sent from subscribed accounts should go through without Lawrence having to interact with them. I'm guessing, though, that nobody has heard from Jay himself in quite some time now. -ethan

WANTED: someone to transfer IBM 5110 BASIC programs to modern PC

by tosteve＠yahoo.com

Hello, A gentleman from the East Coast contacted me to see if I can extract old BASIC programs from his IBM-5110 8-inch floppy disks. I have a working IBM-5120 with internal floppy drives, but the serial communications option is not installed in my system. I think the best I can do is LIST the programs and photograph the screen. Any other ideas? Anyone else with a serial port who can do it? Anyone with a spare communications card? Thanks- Steven Stengel

Sun people and keyboards

Does anyone here have pull with Sun Microsystems or know someone who does? I'm trying to get the right person jazzed up about the idea of a Type 7 keyboard built like a Model M. I've already emailed clickykeyboards.com about it and they'll do the engineering and design work for about $27k. A Type 7 sells brand new for around $50. I'm sure people would be more than willing to pay twice as much for a "Type 7m". -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

I think there's at least one Pioneer with a DA15 serial interface, but I have no idea if there's any sort of standard for them. If you can't find a manual for your AG-LD30, there's always the technique of tracing out the circuit manually. Ground should be easy, then it's a case of looking for, typically, a 1488/1489 pair and divining what your RxD and TxD are. It's probable that there's no handshaking, but I suppose there could be. Not knowing the command set could be a problem, though. Check out AmigaVision to see if it knows about your player. You could then sniff the command set with a serial analyzer. Generally speaking, the player should have commands for start, stop, and seek, at least, and perhaps lock/unlock, eject, and several more directives. When writing apps for a friendly environment, start, stop, and seek are probably the most important commands to figure out. -ethan

Minimal CP-M SBC design

by lynchaj＠yahoo.com

________________________________ Hi, all, I was staring at an SBC I have here with a 6MHz Z-80, some ROM, some RAM, and a 26-pin off-board bus for some Z80-PIO boards (this thing was built as a multi-parallel-printer switcher). I've been musing about what it would take to boot CP/M up on this. For user I/O, I was planning on a console serial port and a terminal/terminal emulator. I have IM6402s on hand, but I'd be interested in hearing if certain other chips are preferred, based on what BIOS code is floating around out there. I also have a 16550, but I don't think I have any Z80-SIO chips handy. For mass storage, I was planning on either Compact Flash or an SD card. I think I've seen both as I googled around for modern SBCs. Any of the media I have lying around is plenty large enough (I even have some 4MB CFs and a 2.5MB full-sized PCMCIA flash card on hand). I am a little unclear, though, about how traditional CP/M systems were set up for ROM and RAM. Was it common to use a "shadow ROM" in low mem at reset, then have the BIOS live at the top of memory? How did 64K RAM CP/M machines handle the BIOS? Did they temporarily ghost the ROM on top of RAM until some bit of code could read ROM and write RAM then bank out the ROM? Since I think I "need" at least 48K of RAM, I was planning on a pair of 62256s. I could easily do 56K of RAM low and 8K of ROM high, I think, unless there's some other arrangement that's obvious to try for a simple design. I've never tried writing a BIOS for a CP/M machine, but my understanding is that things are modular enough that once you know what I/O chips you have and at what I/O addresses, for a straightforward, non-clever design, the coding is equally straightforward and non-clever (but please feel free to enlighten me if otherwise). Thanks for any tips, especially from anyone on the list who has ever rolled their own CP/M machine. -ethan -- Ethan Dicks, A-333-S Current South Pole Weather at 4-May-2008 at 19:40 Z South Pole Station PSC 468 Box 400 Temp -74.2 F (-59.0 C) Windchill -105.4 F (-76.4 C) APO AP 96598 Wind 7.4 kts Grid 77 Barometer 691.6 mb (10194 ft) Ethan.Dicks at usap.gov <http://www.classiccmp.org/mailman/listinfo/cctalk> http://penguincentral.com/penguincentral.html -----REPLY----- Hi Ethan, Funny you should mention the subject, I am working on a very similar project. Last year, I made a completely home brew Z80 computer with prototype boards. It is a fun project and you can definitely build your own CP/M computer from scratch. It really is not that hard. This year, I am remaking the design using manufactured PCBs. I recently got my first batch of prototype PCBs and have been building up and testing them. So far, I have gotten the CPU, ROM, RAM, UART, and most of the glue logic working and tested. It is not complete yet as I still need to wring out much of the hardware and have not even started on the PPI or RTC. However, last year I was able to boot the previous system into its monitor and even boot CP/M. CP/M used a 32K ROM drive for drive A:, a 448K RAM drive for drive B:. I implemented an IDE port and a hard disk for drive C:. Those all worked pretty good. I built but never tested a floppy drive interface. The whole system is pretty simple, uses plain 74LSxxx chips, no programmable parts (except the EPROM) or hard to get parts. No SMT or funky technologies, just plain through hole DIP chips. I have all the software and am presently going through the library reinstalling it on the new system. So far, I have most of the easy stuff working. I do have the RAMless monitor working and next will be the regular monitor. Finally it will be the CP/M system and the RTC software. Anyway, if your interested, I am keeping a small Google group of files and photos at: http://groups.google.com/group/n8vem Thanks! Andrew Lynch

IDE <-> MFM

by aek＠bitsavers.org

> What is the minimum satisfactory sampling rate if one wanted to emulate an ST-412 > interface and have it RLL (2,7)-capable? 2x, assuming you regenerate the clock. With a digital DLL, the incoming clock would be on the order of 8x the maximum incoming frequency. The bitstream is not variable frequency. You can think of what is needed as the inverse of the read recovery circuit on the drive controller. The tricky part is generating the recirculating bit stream that you send as read data back from the simulated drive. It is expecting the data that it just wrote to be in the data read back on the next revolution. And you need one of these bitstreams for each head.

Mohawk Data Sciences paper tape reader?

by chrise＠pobox.com

This one is probably a long shot, but wondering if anyone has any documentation for a Mohawk Data Sciences model 2166 paper tape reader. The unit I have is s/n 2047 and was built by Mohawk, Montvale NJ probably in the early to mid 70's. It's an all mechanical reader with 24VDC solonoid and ratchet that advances the tape. It came out of a Control Data maintanance console for the Star-100, which sadly, as a kid, I parted out. All I have left is the cool aluminum suitcase that it was built in... and this paper tape reader. Chris -- Chris Elmquist mailto:chrise at pobox.com

This Thursday we are getting a VAX 11/785, and we just found out it has no wheels. I have some caster sets that maybe I can bolt on, but I need to know what bolts to use, and if there are any issues (clearance above or below the chassis, for example). This VAX has apparently spent the last ten years of life doing nothing more than an RX01 controller, writing floppies. -- Will

Apparently, there are *150* diskettes to be read... It may be easier to send the computer to him... ....except that it weighs over 100 pounds. --- On Mon, 12/1/08, steven stengel <tosteve at yahoo.com> wrote: > From: steven stengel <tosteve at yahoo.com> > Subject: WANTED: someone to transfer IBM 5110 BASIC programs to modern PC > To: cctech at classiccmp.org > Date: Monday, December 1, 2008, 11:16 AM > Hello, > A gentleman from the East Coast contacted me to see if I > can extract old BASIC programs from his IBM-5110 8-inch > floppy disks. > > I have a working IBM-5120 with internal floppy drives, but > the serial communications option is not installed in my > system. > > I think the best I can do is LIST the programs and > photograph the screen. > > Any other ideas? > Anyone else with a serial port who can do it? > Anyone with a spare communications card? > > Thanks- > Steven Stengel

Open source, stand alone, ASCII terminal project

> > Enough firmware finished now to be a functional VT220 clone > > Including vomit-inducing smooth scroll? :-) Yes, indeed. It turns out that this only took a remarkably small amount of code. I've always thought that smooth scrolling was pretty cool, but never wanted to actually use it. James Markevitch

Sun people and keyboards

by zmerch-cctalk＠30below.com

Rumor has it that David Griffith may have mentioned these words: >Does anyone here have pull with Sun Microsystems or know someone who does? >I'm trying to get the right person jazzed up about the idea of a Type 7 >keyboard built like a Model M. I've already emailed clickykeyboards.com >about it and they'll do the engineering and design work for about $27k. A >Type 7 sells brand new for around $50. I'm sure people would be more than >willing to pay twice as much for a "Type 7m". How important are which features you want? If the "control key is in the right place" feature means a lot to you, you can have that now for only slightly more than Sun wants: http://pckeyboards.stores.yahoo.net/linux101.html Not sure if you can get these in USB, but a PS/2->USB adapter should fit the bill nicely. $70 (and I'll assume plus shipping.) They do have this layout with an integrated catstongue/j-stick/eraserhead/whateveryouwannacallit pointing device for $100. However, these don't have the "extra" keys down the left side of the keyboard. If that's what's most important to you, then that will indeed be exceptionally tough to find, IMHO.

Grid Compass 1109 Computer in Seattle WA area

by michaelgreen42＠comcast.net

Any interest in this? It's very old but outside of my normal collecting habits. The case is in good shape. It powers up but I get a boot error. The screen is also a bit fuzzy but I think just needs adjustment. If you're in the Puget Sound area (or don't mind paying for shipping). Going for the best offer of cash or trade.

Arcade games

by wgungfu＠uwm.edu

Philip - that's a little high for the current market. Maybe five years ago that'd be correct, but now Space Invaders is around US$500-700. A game like Battlezone or Asteroids should be more in the price range he's selling it for. Gottlieb was a major pinball manufacturer based out of Chicago, and since you didn't mention the actual name of the game I can't really judge if the price is fair or not. And yes, there's a longstanding collector and "in home" coin-op market, something we also cater to at the Midwest Gaming Classic event. Plenty of forums, web sites, etc. for the coin-op collecting scene as well. Google is your friend. ;) My guess is, there's someone in their scene right now asking if some amount is a fair price for a vintage computer system and if anyone collects that stuff. ;) Marty ----- Original Message ----- From: "Philip Belben" <philip at axeside.co.uk> To: cctech at classiccmp.org Sent: Monday, November 24, 2008 3:00:25 PM GMT -06:00 Central America Subject: Arcade games Just curious... There's a shop in Coalville, I'm not sure what it sells (maybe it sells games consoles; maybe it's an amusement arcade; maybe both). In the window this weekend were two machines that caught my eye: an original Space Invaders machine from 1978, priced at 895 pounds; and a pinball machine from 1979 (branded "Gottlieb") for an almost-as-unreasonable 495 pounds. (I think at current exchange rates that's about $1300 and $700 US) As I was walking home, failing to hum the Space Invaders song, I wondered what sort of an active market is there for such machines? The prices looked high enough that they must be aiming at serious collectors, or possibly innkeepers who want to create a retro-seventies atmosphere. So do people here know about the classic arcade game market? Are my neighbours of a couple of blocks away being overoptimistic with their prices? Philip. PS What I remember from the period was the many, many attempts to write Invaders-style games in BASIC on the PET and other home computers. And my friend Matthew, after we'd borrowed a Sinclair ZX81 and experimented for a week or two, shutting himself away and writing a quite good one for that machine in machine code - I helped with the BASIC shell that built the initial screen display. And wiring a phone earpiece to the PET user port to hear the sound effects on the Commodore invaders program. And so on... PPS has anyone preserved the Space Invaders song? I sincerely hope not.
