A new AT&T video out today showing their (at the time, the Bell System's) internal CAD and messaging system, TOPES: https://www.youtube.com/watch?v=VKbFM770dus Not a lot of info out there about it but it appears to have run on DEC-10 machines. There are a none of those to be seen in the video but there are a few AT&T/Teletype Dataspeed and Tektronix terminals. Interesting early collaboration system that probably never left Bell - did anyone here work with it? -j

PDP 11/44 avail, Landenberg, PA

by billdeg＠buzz1.com

Accepting best offer for a PDP 11/44 located in Landenberg, PA. Pickup or your arrangements to have shipped ONLY. I am not going to ship this thing. I have not powered it on - first I would need to remove the deteriorated foam behind the front grill and get a 220 adapter (i.e. clothes dryer plug). http://vintagecomputer.net/digital/PDP11-44_2nd/ The cabinet has a little rust on the outside but the computer backplane itself is in pretty nice shape and the module set appears complete. The inside bottom of the cabinet is dirty but by and large it's pretty nice. The cabinet has two tape drive bays in the front and a tape drive inside that I assume to be inoperable, the capstan roller appears to be deteriorated. Happy to answer questions here but I prefer private contact/bids/questions to - http://vintagecomputer.net/contact.cfm thanks Bill

Dead RF31 DSSI Disk..

by holm＠freibergnet.de

Hi all, I've got a VAX4000/300 lately to save it from the dumpster. I've cleaned the machine an powered up. It taked several tries to get the PSU working stable, it shut off itself the first ~10 tries but works stable now. (Yes I know all about forming electrolytic caps but have my own point of view regarding supplying under voltage to switching psu's) The machine is doing the Post until the final displayed letter "3" in the LED Display. The machine is equipped with 64MB RAM, an KA670, and on the QBUS with the KZQSA DSSI and the TK70 Controllers and additional am CMD CQD200. Disks are 2x RF31 one RF71 and a TK70. I currently have no console device connected to the machine, must crimp a MMJ cable first.. The Problem ist, that one of the RF31 Disks doesnt go to ready and the Fault LED lights up. What can I do to further investigate the Drive fault? Are DSSI disks starting up themselves after applying Power and ACLO or has the controller to supply a spindle start command? re those disks known to have sticking heads sometimes? I would do some test on the drive w/o the machine since I don't have any test equipment in the room where the machine now is.. Any hints? If anyone has a spare RF31 or RF71 (or similar) to sell or additional MS670 memory for an hobbyist price, please mail me. I'm in germany, europe. Regards, Holm -- Technik Service u.

HP-1000 and PDP computer parts available

by hpfparts＠yahoo.com

I'd like to thank everyone who responded to my recent post about my computer board collection. The amount of interest is much greater than I had expected, so it has been taking me a little bit of time to sift through emails and contact everyone. If you have not heard from me by now, I've made an error and overlooked you. Please accept my apologies and send me another query. Let me reiterate--I have no asking price for these assets--I have no idea what they're worth and I'm happy that they're going into the hands of people who will appreciate them. If you are interested in specific cards, please make an offer. There is more interest than there are cards, so the only fair way I can distribute them is on the basis of the offers. Regards and 73, Pete AC7ZL

HP board id?

by jwest＠classiccmp.org

It seems over the years I acquired more than a just a few of these (two types of) boards for the HP1000. I'm pretty certain they all came from a batch of about twenty HP 1000 series systems I got that were decommissioned >from military use. They do not seem to be HP in origin, and I don't have any clue what they are for. Mostly they seem to be stuffed with large numbers of op amps and some line drivers. Perhaps just flight line testing or ATP? If no one thinks these are of any use. they will be scavenged for bus driver chips. But I'd hate to do that if they might be historical or "interesting". A few pictures of each board are at www.ezwind.net/hp-unk I tossed in the "-" because hpunk just looked wrong ;) Educated guesses? J

IBM 029 Card Punch and ASCII Machines

by robert.jarratt＠ntlworld.com

I recall back in the late 70s using an IBM 029 Card Punch to punch cards for the DECSYSTEM-20. As I understand it, the 029 was an EBCDIC machine, but of course the DECSYSTEM-20 was ASCII. Does that mean there was an ASCII version of the 029, or that there was something in the card reader software on TOPS-20 that converted EBCDIC to ASCII? Regards Rob

Then put a copy of the will where it can easily be found (such as in your desk drawer). My wife and I are redoing our will and are letting our sons and my brothers know what we are planning. They all will know where to look for the official copy of the will. Bob

Wanted: AT&T 3B2 (buy or borrow) near Seattle

by lists＠loomcom.com

Folks, I started working on an AT&T 3B2 emulator using the SIMH platform late last year. As these things often do, it got side-tracked by life. We moved to Washington state in January, and I've been consumed with other matters since then. I'd like to finally get back to the 3B2 emulator. Having physical access to a real 3B2 would make this process much, much easier, especially one I could put custom homebrew ROMs into. If you have any 3B2s you'd be willing to let me borrow or buy, please drop me a line. I'm located about an hour from Seattle, WA in Kitsap County. Or, if you're interested in a trade, I have some PDP-11 Qbus gear I'd be willing to part with, too. -Seth

CompuServe SC-40 Progress

by b4＠gewt.net

Hello, I've managed to image some of the SC-40 drives (currently just for personal backup use due to any legal issues/possible customer data). I've found in the documentation references to a file named COUGH.DRP which seems to be the CompuServe equivalent of the TOPS-10 Monitor Calls Guide. Does anyone have a copy of the CompuServe COUGH DROPS file scurried away somewhere? It would be very useful in discerning the patches to TOPS-10 and some SC-40 extensions. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Dead RF31 DSSI Disk.. A508 SOLVED!

Hard to believe that a disk can be fixed with that kind of treatment! But I shouldn't be. Remember that scene in one of the early Stars Wars movies where they go to make the jump to hyperspace (or something like that), and nothing happens, and Hans gets up and whacks the bulkhead in a very particular spot, and then it works? I first saw that movie with a couple of people from the MIT computer lab, and we were all convulsed with laughter at that scene. One of our mainframes had a sticky power relay, and when you hit the 'power off' on the front console, nothing would happen. So you'd walk around to the back of the machine, open a door, and give a particular box a good whack in a particular way with your fist, and it would power off. Some things just never change! Noel

Running a Z8-02 MPD on a breadboard

by spacewar＠gmail.com

Some time back I acquired a Zilog Z8-02 MPD. This is the bond-out version of the Z8 microcontroller. The normal Z8 contained 2K of internal masked ROM and was packaged in a 40-pin DIP. The Z8-02 had no masked ROM (or possibly the masked ROM was disabled), and the address and data buses for the internal ROM, along with a few clock and control signals, were brought out to the extra 24 pins of a 64-contact ceramic leadless quad-in-line package (QUIP). Typically for emulation it would be used with a 2716 EPROM, or 2KB of RAM with address and data multiplexers for a fancy emulator. The ceramic leadless QUIP package was used for bondouts from Intel and Zilog, and later, for the Intel iAPX 432 components. Later it was replaced with the square JEDEC ceramic leadless package. Note that the ceramic leadless QUIP is unrelated to the more common leaded QUIP packages used by NEC, Rockwell, and Motorola. Unlike many modern leadless packages (DFN, QFN, BGA), the ceramic leadless QUIP is intended for use only in a socket, which was made by 3M. Today the sockets are even harder to find than the chips that require them. I designed a simple QUIP adapter for use with solderless breadboards, and wired up a Z8-02 MPD along with a 28C16 EEPROM for the program memory, a 62256 static RAM, address latch, and decoder. I programmed a copy of the Z8671 Basic/Debug interpreter into the EEPROM. To my amazement, it worked the first time. Photos: https://www.flickr.com/photos/22368471 at N04/sets/72157652653732622 The last "photo" is a screen shot of Kermit talking to it. I've entered an inefficient program to search for primes, and the screen shot shows it being LISTed, RUN, and then stopped after a few primes have been found. Not shown, I printed the value of some of the interpreter's globals, to verify that the static RAM was recognized properly. (The interpreter can actually provide minimal functionality with no external memory!) While Zilog only claimed it to be a subset of Dartmouth BASIC, the interpreter does not include the FOR statement, so IMNSHO it barely even qualifies to be considered a "tiny BASIC". The competing National Semiconductor INS8073 had 2.5K of ROM, and Intel 8052AH-BASIC had 8K, so they supported more features of BASIC.

HV tracking across flexible PCB strips

by jules.richardson99＠gmail.com

I really couldn't think how best to word the subject. I pulled the CRT out of the HP 1331 X-Y display that I got the other day, then took all the old tape off, cleaned it up, and reassembled with new tape. It's no longer arcing around the CRT face, which is good. However, there's a flexible plastic strip running between the CRT face and the chassis which carries three lines (it's a storage tube rather than a conventional CRT) and I'm still getting periodic arcing across these lines which of course upsets the display's operation. As far as I can tell, there's no 'sandwich' (and hence glue) involved - it's just a single plastic strip with conductive traces drawn onto it. Does anyone have experience of these kinds of strips in an HV environment, and what (if anything) can be done for them when they start to fail? Possibilities seem to be: 1) Try some more cleaning, 2) Reworking with conductive paint (I wondered if one or more of the traces have gone high resistance in certain spots and this is encouraging the HV to arc between them 'upstream' of such areas), 3) Plastic itself has broken down in some way, requiring replacement; has anyone managed to make a replacement strip from scratch? Although I've not tried the actual X/Y/Z inputs yet, basic write/store/erase functionality and beam movement via the front X/Y controls seems to be working so long as the arcing isn't occurring, and it'd be a fun little gadget to get working. cheers Jules

HV tracking across flexible PCB strips

Maybe I'm misunderstanding something, but why not apply a layer of tape immediately on top of the conductors - since a thickness of .X of a mm (through) will insulate 22KV, Y mm (across - where Y is the distance between the conductors) definitely ought to do it. Although there is the glue that holds it down - I wasn't sure if that was the glue you were referring to, or if you meant some other glue - that might not be as insulating (or maybe it is, just don't know). But, anyway, if the glue might be an issue, you'd have to apply the tape non-glue side down (and stick something like regular electrical tape to it, glue-glue, to nullify its glue on the now-up-facing side - unless you want to use that to join the two layers of the original together). As to how to get it to adhere: if you can figure out what the insulating glue was that they used originally, or some modern facsimile thereof, you could use that. Noel
