A co-worker here on the help desk had gotten a replacement, because this one wasn't getting phone signal anymore. I started using it so I could be familiar with it; for when users call in to get help with thiers. I would think Ubuntu Linux counts as a (fairly) real computer.

Looking for a Tally 420 tape puncher and a 424 tape reader

by wlsilva＠sbcglobal.net

Looking for a Tally 420 tape puncher and a Tally 424 tape reader, we need these for a restoration project for a Telemetry console that was used in the Titan rocket program. The Tally units that were in the operators console are missing, and we really would like to replace them for proper display. Here is a link to a photo of both units http://www.dvq.com/ads/tally_dm_11_60.jpg Many thanks. Walter Silva

pdp8/a core memory to trade! Ohhhhhh!

by hachti＠hachti.de

Hi, I'm kinda out of my head... I bought a pile of Omnibus boards from someone on eBay. Lots of boards for even more money. I got some Dataram core memory modules for pdp8/a. One 8K and three 16K modules. I expected them to be quad wide. I explicitly told the seller that I'd be interested only if they're quad wide. He sent me a photograph of a quad wide Dataram module. And what I got is hex wide. I'm going crazy... I spent all my money on that deal. In the hope to get enough core to fill my pdp8/e and /m. I'm really frustrated. Does anybody have quad wide core memory for Omnibus and wants to trade for pdp8/a memory? Examples: For one "single board" 16K module (not made by DEC) I'll give one 8K and one 16K DataRAM module. For two single board 8K modules (not made by dEC) I'll give one 16K DataRAM module and one H219 8K module. For three DEC 8K module sets, I'll give one 16K DataRAM module and 2 8K H219 modules. For four DEC 4K module sets, I'll give one 8K H219 and one 16K DataRAM module. If there are some larger amounts of 8K modules out there, I'd could throw in a set of pdp8/e CPU boards. Generally, I try to trade 3:2=8a:8e. If someone has something to trade, PLEASE contact me. I'm quite desperate because I spent all my money for the stuff. Best wishes, Philipp P.S.: I could use a single DEC 4K core board as well...

Looking for key of IBM console

by quapla＠xs4all.nl

Ok, I have this IBM console and I'm looking for the key and possibly some replacement bulb's. The bulbs are some sort of little tubes made of clear plastic, and they contain an even smaller glass bulb. I might be able to open them up and replace them with white or yellow led with a small series resitor, but it looks like it's not that easy to do. See the pic at http://tinyurl.com/yjnt9cn Any other suggestions I could do with it? Ed -- Certified : VCP 3.x, SCSI 3.x SCSA S10, SCNA S10

Getting P4 video to work in a Sun 4/110

by derschjo＠mail.msu.edu

I've decided to play with some of my older Sun hardware this weekend, it seems :). I have a 4/110 (Sun's first desktop/side Sparc machine) and two P4 video cards -- a CG4 (501-1248) and an MG3 (501-1247). I can't get the 4/110 to see either of them. Running boot diagnostics shows it probing for a card in the P4 slot but not finding anything. I've hooked the CG4 up to a monitor and the monitor syncs with it and displays a blank screen, so it's getting power and doing something, but for some reason the machine won't see it. Any ideas? Thanks as always... Josh

S-100 IDE project

by lynchaj＠yahoo.com

Hi! My good friend John and I are working on a joint www.S100Computers.com & N8VEM <http://groups.google.com/group/n8vem> S-100 IDE project. It is based on the following design by Peter Faasse. http://www.pjrc.com/tech/8051/ide/wesley.html John built a working prototype and some software and I am making a PCB. The PCB is in trace route optimizing phase now. I can't say exactly when a PCB will be available but if you think you might be interested please let me know. PCBs will probably cost *about* $22 give or take some plus shipping. If you do want a PCB it is important you tell me beforehand so I can include it in the manufacturing order. The board will connect to regular IDE devices and includes mounting areas and interfaces for laptop (2.5" with the high density 44 pin connector) and CF adapters. John has his prototype working with a CF adapter mounted on the PCB and it seems to work fine. Thanks and have a nice day! Andrew Lynch

You can help to solve the greatest mystery of all mankind! Help identify this printer from 1966, hardest item I have ever tried to find information on.

by wlsilva＠sbcglobal.net

Hello I am trying to identify this rack printer from the time period of 1966. The printer circled in this photo http://www.flickr.com/photos/19997518 at N02/4085043282/ is the unit in question, it was made by "Franklin" , and you can imagine the search results I get when searching for "Franklin printer" EVERYTHING is about Benjamin Franklin. The equipment in the photo is a Delco missile guidance telemetry monitor, I have seen photos of the same printer used in Nasa tracking station equipment from the 1960's, and I know that a aircraft version of the printer was used in military planes of the same time. We are trying to restore a Delco Telemetry console from the 1960's that is missing the Franklin printer, and we would like to try to find one to replace the original. If anyone can provide information about the company that made these printers (I assume they went by the Franklin name) or can ID this actual printer model, it would be off immense help for us, we assume they were a USA company, but that is all I know. I did get to talk with the gentleman that was in charge of the Delco telemetry dept in 1967, and the only information he could recall is that the printer was a impact printer, made by Franklin, and was a high end unit for its day. Thanks to all, and silly prize to anyone who can solve this ! Walter wlsilva at sbcglobal.net

S-100 IDE project

by lynchaj＠yahoo.com

Reply to http://classiccmp.org/pipermail/cctalk/2009-November/278452.html Hi! John has some CBIOS software for CP/M 3.0 based on his system. I do not know what the maximum drive size is but on the N8VEM DiskIO board CBIOS for CP/M 2.2 the maximum size is 8MB. I believe the 8MB limit also applies to the S-100 IDE board. At least in theory you could implement your own CBIOS extensions for partitions and the like. We are doing something akin to that on the N8VEM project for the SBC DiskIO CBIOS. However that is a completely separate project from this board. Anyone who gets one of these S-100 IDE boards would have to integrate it into their CP/M system using the PCB, the schematics, and the example code. No further support is offered. As John wisely says on comp.os.cpm "Please note these would be bare cards, a schematic and that's it. Building the board and implementing CPM etc., you are on your own. This is not a project for first timers." There you have it -- Caveat Emptor. Thanks and have a nice day! Andrew Lynch How are you getting around the 8meg max drive size common with CPM ? Are you splitting it into many small drives in hardware on in the driver like Morows dod for the M26 ? I have an old MPM system that had an M26 on it I would like to bring back to life.

A few classic computer photos

by ard＠p850ug1.demon.co.uk

I've put a few photos of mostly classic computer stuff on flickr. From memory, there are some floppy drives coming apart, the boards from the HP9820 calculator, repairing the printer and card reader for that machine, upgrading the memory in an HP integral and an HP42S, and a few more. Do a search for tony_duell to find them.. Don;t try to make sense of the 'photostream', the sets, howerver, are in a sane order. Enjoy -tony

design rules for classic computer PCB projects

by lynchaj＠yahoo.com

Hi! I've been doing some PCB design work for various classic computer projects and would like to discuss and hear some advice from experienced PCB designers regarding design rules. What design rules do you normally use for vintage and/or classic PCB projects? Clearly the design rules depend on the application and technology involved. Normally, my projects are in the style typically from the late 1970's and early 1980's style technologies such as PC/XT ISA bus, ECB, S-100, etc. The components are typically 74LSxxx TTL DIP parts meant for easy and reliable construction. There are no SMT components or very high frequency signals. My typical starting design rules are 17 mil traces for signal, 51 mil traces for power (VCC and GND), air gap (min clearance) of 11 mils. Grid size varies depending but usually is 25 mils although I prefer 50 mils. Component pads are typically 55 mils diameter with a 32 mil hole. Connector pads are 60 mils diameter with a 40 mil hole. These parameters allow for a single trace to be routed through the pins of a typical device. Vias are 45 mils in diameter with a 25 mil hole. There are no blind or micro vias allowed since all of my projects are use 2 layer PCBs. Normally the signals for my projects are in the range of 1-8 MHz. Occasionally there is signal as much as 16 MHz clock but those are few. The harmonic content would contain higher frequencies since this is almost entirely digital circuitry and square waves are prevalent. I aggressively review and optimize the PCB layout and trace routing to minimize vias and overall trace length. This phase can be very time consuming but I think it is worth it. Of primary concern to me is trace length due to legacy busses, board density, size, and mainly using 74LSxxx technology. I've found longer traces can result in greater impedance for both signal and power which can interfere with proper operation. As a result I am using the 17 mil signal traces and 51 mil power traces to minimize impedance and the resulting voltage drops. Long traces can also have other effects which can raise havoc on digital circuits. Solid power supply rails is important so when I think a design is going may use a lot of power I specify 2 oz copper weights although for most PCBs it is only 1 oz. The wide signal and power traces are where I think my designs might be overly conservative. The really old PCBs I have seen are as much as 20 mil signal traces but most recent PCBs are less and around 10 mils and sometimes smaller. Minimizing switching transients is important so I normally place a 0.1 uF bypass monolithic ceramic capacitor per IC. Normally there is a larger 22 uF electrolytic or tantalum bypass capacitor placed across the main VCC to GND supply rails at the entry point to the PCB. So far the PCBs have turned out to be fairly reliable and easy to build. There have been a couple of errors but those are cases of where signal or power traces were either connected wrong or left off entirely due to EDA library problems. Things seem to be working fine although I am curious as to what other designers are using and why. I would like to improve my projects to make them the best possible and if there are ways to reduce trace length and minimize the number of vias. There are some sources of information on the internet regarding PCB design but much of the recent material is focused on SMT, low power, and/or very high frequency components. Often times I see trace widths less than 8 mils which to me seem quite hazardous. Here is a good link for some discussion on how to design a PCB for reliable manufacturing. It is about the right age for the projects I like to work on and the design rules are fairly consistent with mine but not exactly. I tend to be a bit more conservative with regard to larger trace width than the author. http://www.pic101.com/using_tango.htm Thanks in advance for any advice and/or insight on proper PCB design. I appreciate your thoughts and comments. Please no flames, this is intended to be a serious and on topic question. If you are going to change the topic please make a new subject. Thanks and have a nice day! Andrew Lynch

HP monitor and keyboard available

by henk.gooijen＠hotmail.com

Hi all, whilst cleaning out, I found an HP monitor with accompanying keyboard. A label on the keyboard reads C1400A (?) and on the monitor is a label that says 700/92 and 1001G. They are in working order, the screen lights up green, characters are sharp, so the CRT is fine. I guess that it will be local pick up only in Helmond, The Netherlands. Shipping in The Netherlands will probably cost just 6.75 euro, but outside the country will get too expensive. I am willing to ship it though, just hate to trash it, but that's going to happen in a week, if nobody wants it. - Henk.

HP 900/300 with HPUX and Windows ??? info needed

by g-wright＠att.net

I have a couple of HP 9000/300 series computers with HP 7953 drives and Intel processor cards in the computers. These have both HPUX and Windows on the same drive. It looks like the Windows file system shares the HPUX file system on these ?? What I want to do is backup the drives. Just want to make sure I get it all. If I do a "ls" under HPUX it shows both the HPUX and Windows files and directories. Along the same lines,does anyone have early HPUX tapes. I would like to come up with 9.x and earlier. I have backups of drives but no way to get the backup on to a drive that has failed. Thanks, Jerry

I wouldnm't call the former a 'favourite', although I have 3 or 4 of them with an assortment of lenses, flash, motordrive, etc. It's certainly an interesting camera, although too much electronics (and no manual override) for my taste. But Exaktas I love. I generally describe them as the 'Citroen DS of 35mm cameras' (if I ever learn to drive, a DS is top of my list of desirable vehicles...). The Exakta is totally unconentional. Every control is where you don't expect it. But then it has shutter speeds from 1/500 (or 1/1000 on later models) to 12 _seconds_. A film cutting knife (and you can run cassette-to-cassette) so you can cut off an process part of the film. Interchangeable viewfinders (I must repair the metering prism I have for mine -- alas the meter coil itself is open-circuit). And so on.

Yes, I like them... -tony ------------------------------ Tony, You might like looking at? http://captjack.exaktaphile.com/ ?.

Origins of Internet, old Physics Today article

by mtapley＠swri.edu

All, Catching up on my old magazine stack yesterday, I came across what looked like a good article in Physics Today (Nov. 1998, Vol. 51 No. 11) entitled "The World Wide Web and High-Energy Physics". It described the steps leading to the evolution of HTTP, HTML, and the adoption of those protocols at CERN and elsewhere. Nice photos of Tim Berners-Lee sitting in front of a NeXTStep screen, and *the* Cube that ran the original server. The article appears to be on-line at: http://www.physicstoday.org/archive.html (click on 1998, select the Nov. issue with the icebreaker on the cover, look in "articles". I have to admit though, my Safari 4.0.3 and Firefox 3.5.1, both on Mac OS 10.4.11, fail to display the article .pdf they think they are serving. Did anyone else note this article, and can comment on its accuracy? Does anyone want/need more info? -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

Junkyard Cray

by wdonzelli＠gmail.com

I saw some Cray debris in my latest electronics junkyard - the three section power supply seat for an X-MP/24. Yes, X-MP. They came in with a load from Canada, and the odd thing was they clearly had been junked recently, as the conductive schmutz on the busbars was still sticky, yet not full of an accumulation of crap from being exposed for year. I am sicking the owner on the rest of the machine, but it is very likely to have been cut up by now. Still, any Cray owners need a few spare power units? -- Will

Looking for LED display of a HP33E or HP34 or similar

Hello, due to my playing around with the LED display from a busted HP34C (see my projects page, from my .sig) I got contacted by someone with a HP33E that needed a new LED display - his was faulty, so I agreed to send him my display - in fact I sent him the entire HP34C, given that there might be more bits useful to his restoration efforts. Long story short, due to my naivet?, the calculator got lost in the mail, so it appears. I _never_ lost anything in the mail, it wasn't a get-there-or-else kind of package, so I figured I save a few bucks and send it as regular small parcel - no tracking number. Well, live and learn, as they say. I guess with international shipments, bad things can still happen. So, is there anyone on the list who has a display for that type of HP calculator (I think they got used in several of the 3x series)? It should look like this: http://www.ece.mcgill.ca/~jthiem/project-files/HPLED/HP%20LED%20display%20u… I'm hoping _someone_ has one hidden away somewhere that wont power up due to failure other than the display...

Minor editorial/wording changes and the final page was split off into a "box" in the magazine, but same content and same illustrations. Yeah, for $23, Physics Today can keep the editorial modifications :-). Thanks, Kevin! Now that I know everyone has access to it, I can recycle my paper copy.

Speaking of VAX memory... MSV11PK->MSV11PL?

by ethan.dicks＠gmail.com

Hi, All, Today's threads about maxing out VAX4000s reminds me that I've been meaning to ask if anyone has fully stuffed a 512KB MSV11-PK and turned it into a 1MB MSV11-PL? I have the requisite handbooks and know how to strap the cards and such, but having in the past upgraded DEC memory cards, I remember the "joy" of sucking out hundreds of holes and looking for cold joints when the card didn't work the first time I tried it (eventually, I did get it to work). I just haven't done it with a card that's more than a dumb block of RAM (the MSV11-P series has a CSR for querying parity status, among other things). Abstractly, I expect it's a matter of cleaning the solder out of the pins, installing a lot of 4164s (the card supports 4116s or 4164s), then changing a strap or two for the extra fields. I'm just wondering if anyone has done this and found and surprises. I'd love to just have a pile of 4MB Qbus memory lying around so I didn't have to fuss with things (for those that don't know DEC equipment, 4MB fills the memory space on a 22-bit Qbus (no PMI) machine), but I think I have exactly one card that large and it lives in a MicroVAX I. Thanks for any tips or warnings, -ethan P.S. - someday, I may try the same with an M8417 to turn an MSC8AA (16K) into an MSC8DJ (128K) by removing the 4K DRAMs and fully-populating the card with 4116s. The sheer number of solder joints to get right has held me back on that one.

Talking to a VAX4000/300

by jplist2008＠kiwigeek.com

Greetings all; I picked up a VAX4000 last week and have been trying to get talking with it. I found a general VAX4000 series guide which says the terminal settings should be 8N1 and I've got the speed right between the dial on the front of the VAX module and the VT240 I'm using. I get partial data, with ?s scattered all over the place. Frequently it loses carriage returns and things get stuck scrolling off the side of the screen. What am I missing here? Is it not 8N1? I've tried flipping it around to 7N1, 7E1, etc, but usually that just results in absolute gibberish, the 8N1 provides the best signal-to-noise ratio. I'd appreciate any thoughts given. Elsewise, I'm pretty pumped. I have another 4000/300, but it has a bad PSU. I figured I'd put the two together to get the nicest working machine, store the spare PCBs and dump the chassis (anyone want an empty 4000/300?). The unit is complaining about some memory errors (came with four memory boards), but with all the crap coming up on the screen, I'm not entirely positive what it's complaining about since I can only read a partial output... Thanks again; - JP

Panasonic JA751 8" drive question

by snhirsch＠gmail.com

I just purchased one of these on ebay, but am unable to find even a shred of documentation on the web. It's equipped with a "PC" style 4-pin Molex connector for power, unlike the more usual 6-pin square connector used by all my other 8" drives. What I'd like to confirm is whether this unit can actually run on 12VDC. It does not seem to work correctly with 12V applied, which could suggest either that it requires 24V or is defective. Before I let the magic smoke out of it, does anyone know the proper voltages for this drive? Steve --

386 upgrade boards for IBM 5160s

by brianlanning＠gmail.com

I have a chance to buy an IBM 5160 (pc-xt) with I believe an original CGA (iirc) monitor. The interesting thing is that he seller claims it has a 386-16 upgrade board. What do we know about these? How much would that upgrade board be worth? I'm trying to figure out if his price is fair. brian

Why I never saw my own posts!

by snhirsch＠gmail.com

Thanks to help from the list admin, I have figured out why I stopped seeing my own posts to the list! Seems that gmail, in the their infinite wisdom, decided that it would be best for me if my own messages were shunted directly to 'archive' and never appear in the incoming folder. There is no control or option that I can find to turn this "feature" off. Subsequently, I've had to change my list subscription to use my ISP's mail service and all is well again. Talk about obnoxious! I'm starting to wonder if gmail isn't more trouble than it's worth. On the good side: It's free and their spam filtering is very effective. On the bad side: They silently drop most binary attachments, both coming and going, with no consistent policy involved that I've been able to determine. And now, this. Steve --

My email address: t.gardner-AT-computer.org FWIW, the WD1003V is the 1986 version of this line. I'm not sure exactly which model shipped in the first PC/AT other than I am pretty sure it was of the WD1003 family. Tom

Kiel PDP 10 and RP02/03 disk drives

I sort of missed most of the discussion on the Kiel PDP10 but in going thru some of the dialog I came across this quote from one postings: > The Kiel museum/collectors society who were tracking the University's > computing department's "output" for many years saved a complete system > consisting of two KI10 (not sure, but older than KL10) processors, > memory, drum memory, peripheral controllers, and some peripherals.

I > personally saved some stuff (RP drives, RS04 drives, CR10 card reader), > the biggest part went to collectors who have in mind to get the stuff > working again. I worked on the Memorex 660-1 which is the RP02. The RP02 (Memorex) and RP03 (ISS) are really significant early hard disk drives and I would hope the Computer History Museum would be interested in samples of both. Can someone give me some status - where have they gone and are any still available for collecting? If any are available, I can then work with the museum to arrange for collecting them. If they are not available, it would still be great to know where they are for reference and possible future collection. Tom Gardner Los Altos CA USA
