Motorola EXORset

by lynchaj＠yahoo.com

Hi! Does anyone have the schematics for the Motorola EXORset? If so, would you please either make a scan or look something up for me? I would like to know how the MC6840 PTM interfaces with the MC6809 CPU. Thanks and have a nice day! Andrew Lynch

Parts bonanza

by snhirsch＠gmail.com

Anyone within driving distance of Windsor, VT might want to get in touch with Brad Thompson at WinCycle: wincycle at wincycle.org They are nominally a computer recycler who handle the usual castoffs, dead notebooks, off-lease PCs, etc, etc. Recently, a local landlord gave them the entire parts inventory of a local manufacturing company who went bankrupt and abandoned it. They made the entire thing available to local hams and hobbyists for free (or a small donation if you really felt guilty). We went down with a couple of storage tubs and filled them to the brim with tubes of unused 74-series and CD-series logic, machine-pin sockets and more resistors and caps than you could even imagine. All of this is pre-surface-mount through-hole componentry. An entire afternoon's picking didn't really make a visible dent - there's that much stuff. I would estimate many hundreds of tubes of chips and sockets and tens of thousands of caps, resistors and other small parts. I would suspect we were looking at > $100,000 worth of components at original cost. When we left, he mentioned that they might do this again next Saturday. At some point, I'm sure they will sell whatever remains to an industrial auctioneer or serious flea-marketer. So if interested, I would suggest moving quickly. Steve --

Shipping a Tek 'scope

by jules.richardson99＠gmail.com

I'm not reading here much at present, not until I eventually get all my collection moved, but I did just get offered a Tek 545A which is languishing in a garage down in Texas, so figured I'd ask about shipping it safely. Weight seems to be 65lbs according to the manual, but I've not poked any shipping companies yet to see how much it'll cost to get it up here to MN - perhaps it'll end up being just too costly on those grounds. Current owner's happy to pack it for me and drop it off to a shipping company (and apparently they have a Craters and Freighters about 5 miles away from them). Obviously styrofoam "poodle poop" is not a good idea - presumably a higher-density material of some kind would be good, and something that's not going to shift around too much. I wondered about some slabs of that styrofoam stuff they use as house insulation, cut to fit, but maybe that's *too* solid and won't absorb any impacts. Oh, and obviously something softer would be needed on an inner layer to protect all the controls at the front of the 'scope... Do people recommend pulling the tubes/valves and packing and shipping separately, or will they likely be OK in-situ? I'd be doing a strip-down of it anyway (it's not run in a couple of decades) - but with over 100 of them it's a lot of work for the current owner, plus I hate getting stuff already-dismantled and prefer making notes as I disassemble it myself. cheers Jules

Compupro and PET/UNITRON/TI etc. systems posted earlier

by dave09＠dunfield.com

Thanks to everyone who responded. I will be preparing a list of the responses received (in the order received) and forward them to the respective people with the systems, and they will take it from there. Sorry if my "contact me for more info" turned out to be misleading, I was hoping to have obtained permission to give out their contact info, however neither has responded yet, and apparently people from the list are getting impatient. At this point the best way for me to handle is to forward the messages I've received to the parties and let them handle it, as I have no further information to give out yet. Please stop sending emails asking if I've received your previous messages, if the systems are still available, or other questions - I know only what I posted.

Will, I think it's the wrong "GR", but an interesting story. From http://www.cs.uiowa.edu/~jones/arch/risc/ "Sidenote: Saul Dinman explained in 2003 that GRI was originally General Research Corporation, a private Massachussetts company; when it went public, it had name conflicts with a pre-existing General Research, and then with General Radio as it hunted for a non- conflicting name. Under the name GRI, the company was eventually acquired by venture capitalists in North Carolina, and then by a display manufacturer that wanted to buy their OEM supplier, and finally by Analog Devices. The GRI processor architecture was one of the first bus-oriented architectures built using a printed-circuit backplane. Thousands of GRI-909 systems were sold on an OEM basis, mostly in the industrial control sector. Had marketing and capitalization worked out differently, the GRI-909 might have been an effective competitor for the Data General Nova, another DEC spinoff." So I guess that any remnants of GRI might be in AD's archives...

If you just want to play games or a few old apps you can get by with a simple system, monitor, keyboard, dual 3.5" and dual 5.25". I have a Transwarp IIgs, 8mb RAM card, rev C SCSI card, and I mostly just boot from floppy and play games. All the extras are nice if you use GS/OS and want to transfer images and files around (and read HFS partitions or network with a Mac), but if you have an old Mac you can make usable disks there. You can still find systems on freecycle if you post a wanted, they will most likely be basic setups (teachers seem to snag them for their kids and then get rid of them when the kids get older). ------------------------------ Message: 15 Date: Thu, 12 Nov 2009 11:00:38 -0800 From: jim s <jws at jwsss.com> Subject: Re: Walkthrough of a small datacenter 1992 To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Message-ID: <4AFC5B56.9050309 at jwsss.com> Content-Type: text/plain; charset=UTF-8; format=flowed rmg at ranma.com wrote: > Just ran across this list.

I have a friend who may have one of the Micom boxes. We used one in our office for terminal access. Also interesting is that one seemed to have to waste paper to keep the systems running.

apple documentary and huge apple collection

by brianlanning＠gmail.com

We've been watching netflix through the xbox 360 lately. They have a documentary about apple that started out good, but sort of went down hill I think. (it seemed a few years old, so you may have already seen it) But toward the end, they showed a guy with a huge apple collection. He makes all of us look like amateurs. He doesn't have a storage facility. He has a 6000sqft building. It looks like a small office building. He also had machines in his basement, attic, and in a storage shed that looks more like a 2-car detached garage. In the video I saw maybe 40 or 50 apple 2es. I like stuff like this. It give me something to point my wife at and say, "see, at least i'm not like that guy!" lol http://www.netflix.com/Movie/Welcome_to_Macintosh/70112046?strackid=7c44782… brian

That's fascinating. I'd seen "passive" ballast tubes for heater regulation, but not an "active" solution like this. I found a good write-up at: http://www.radiomuseum.org/forum/2as15_how_it_works.html Especially interesting to me is the mechanical link in the diode that shorts it out when the filament burns out, pulling down the regulated voltage. I wonder if they learned the necessity of that the hard way. John Finigan

JiffyDOS Forensics

by brain＠jbrain.com

Please feel free to repost on other forums, I'm trying to catch as many people as possible: As many of you are probably aware, I acquired a license to sell JiffyDOS earlier this year and am now ramping up sales. To that end, I am trying to reconstruct the exact product offerings that CMD offered. This means verifying images, and determining what original ROM images CMD supplied with each overlay. Thus, if anyone can use a DOS ROM reading utility (or EPROM reader) and can send me a copy of the both halves of the JDOS ROM, I'm still struggling with the following systems. 1571: I have three versions here, but cannot determine which is correct. The MD5s are: 41c6cc528e9515ffd0ed9b180f8467c0, 6b4d46b28b7414d5a82cea4972894600, and d649fa6b0108c20ce213f5496d5980a5. What is the version number on the ROM sticker?) 1571D: I have a 1571D JiffyDOS ROM here, but it looks to be a 1571DCR (the cost reduced version). Notes indicate a non-CR 1571D used a normal 1571 JD ROM overlay, but I'd like to verify that. MSD SD1/SD2: I am trying to determine the version of MSD code in the lower half of the U5 JiffyDOS for SD2. The MD5 is 1a2efac3b96decf83fba27bc17c5a8a7. I checked against my SD2-2.3 version here, but they are different. Also, is the SD1 JiffyDOS the same as SD2 version? Indus GT: I do not have an original JDOS for this, so I need a dump to compare. 1541C: Again, I do not own an original JDOS for this machine. I understand there is a Swedish version of JiffyDOS for the C128 and C128D (and possibly for the C64) [Update: I have been sent copies of the Swedish JiffyDOS ROMs, but I'd still be interested in what version of KERNAL was included as the "original" KERNAL for these units.] German/Finnish JiffyDOS variants? Any help folks can provide would be much appreciated. In fact, if you have an original JDOS, no matter the type and can dump it for me (both the original and the JD portions), that'd be great. Anything you can tell me about the setup - sticker legend (version number, etc.), machine variant (128, 128D, 128DCR, etc.), video standard (PAL/NTSC), and whether it had a switch on the ROM - is good information to share. To clarify, I know there are bootleg archives available, but I can't consider them authoritative. In addition, the archives would not tell me what CMD placed in the non-JD half of the EPROM on units with switches. I would prefer to check against genuine copies of the overlays if at all possible.

Having the day off, I finally uploaded some new pr0n to the Alpha Micro Phun Machine, including pictures of the AM-1000 and AM-1001 I got recently, and the AM-1041 S-100-based system that I'm hoping to restore and get operational in the not-so-distant future (hi Bob!). I also included a download for the fingerproxy, which I'm using to give arbitrary TCP socket access to older AlphaTCP installations.

Cool! I had a similar one, a 543 IIRC, that was the only major piece of tech-junk I lost to hurricane Katrina. I still grin thinking of my complete panic when I looked at one side panel and saw a big orange glow in the tubes next to the power transformer. Got the side off and realized it was a neon filled voltage reference tube, not a glowing plate. Anyway, the things are a treasure trove of interesting tubes. I like the tiny soldered-in (baseless) HV rectifiers, tube regulated B+ system, and the electromechanical time delay "tube" that lets the thing warm up before applying HV. It's interesting to see tube design in "cost not much of an object" mode. I used to have Stan Griffiths' book "Oscilloscopes: Selecting and Restoring a Classic". I don't remember it being particularly technical, but it has tons of info on the Tek tube-era product line, and was fun to thumb through, if you're into that kind of thing. John Finigan

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...

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. Among the 35mm Exactas around me at the moment is a VP exacta taking 127 roll film (6*4,5 cm frame). 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

by joachim.thiemann＠gmail.com

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...

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 --

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 --

Kiel PDP 10 and RP02/03 disk drives

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

Doesn't mean it's Not got a grain of truth behind it though. The reason given (internally to DEC, by the group responsible for these drives) for not being able to proceed past an inadvertent write (or physical damage) is that the drive is kept constantly synchronised by the stream of data that it reads. Once it loses that synch it no longer knows where it is and cannot recover. The stream of data is then just so much noise. The only recovery possible is at the beginning of a new data stream. Assuming that all of that was true (and, indeed, correctly remembered ...) then once you hit physical damage, the way the drive works will not let you recover data past that point. It's a feature. There may or may not be special firmware, but I've never heard of any. So I'd be willing to believe that a TF drive might handle some issues better than a TZ drive (although I'd prefer to see some corroborating evidence before repeating this meme myself), if you've got a damaged tape I'd be very surprised if either drive makes any difference at all. That's not a reason to avoid a TF85 or TZ85: you never know when you'll need one for some other tape you do want to read. Just don't sped too much! Antonio

Is it not the case that the TZ85 (SCSI) and TF85 (DSSI) are the same drive, jus twith a different interface? So a TZ85 may be as useful to you in solving your problem. As for solving your problem, a perennial complaint within DEC was "I've somehow started scribbling half-way along a DLT tape but I stopped quickly and I need to get to the half of the data beyond the scribbling". I never saw anyone admit to having one of these problems solved: even when there was a paying customer at the end of a cheque book. The existence of special recovery firmware was firmly denied - and I never saw even a hint that it might exist. So I don't have any reason for believing that a TZ85/TF85 might be any better or worse at reading your data than anything else that can handle your DLT. BTW iirc the TZ86 and TZ87 are (iirc) can read tapes from a TZ85. The TZ87N lost some of the backwards compatibility (to lower costs). Antonio

VAX-11/750 w/o POWER OK indication

by oldcpu＠rogerwilco.org

After a very long time[1], I have gotten very close to having a functioning power supply. I'm still not quite there by the looks of it. With a dummy load of two automobile headlamps (four filaments wired in parallel) for each of the 2.5V and 5V supplies, I now have pretty decent voltages: 2.54v (2.5V supply main output) 5.21v (5V supply main output) 15.31v -15.18v 5.08v (+5VB) -4.98v (-5VB) 12.09v (+12VB) As far as I can tell, after going through the "H7104 Power System Tech Desc" doc, these voltages are good. Even the slightly high 5V line is within the spec'd range of +/- 5% or 4.75v - 5.25v. Still, I don't see a green POWER OK indication on either the power controller or the cabinet's front panel. What I do see on the front panel is a red FAULT and a green (slightly dimmer) RUN indication, but this is probably because no boards are yet in the backplane. There are no lit fault indicators on the power controller itself, which suggests that the voltages are okay. Another list member who saw similar symptoms on his 11/750 apparently found that it was loose contact in the Power Control ribbon cable, but that doesn't seem to be the case here. To test this further, I toggled the 5V supply's test switch to LO and saw the voltage drop to 4.97V, but the POWER OK lamp still didn't light up, so I don't think the problem has to do with the 5V output being too high. I should put my 'scope on it to see if the output is stable. I'll do that, but I'm guessing that it's going to be good, and I don't know if the power controller is sensitive to that anyway. I haven't checked the POWER OK lamps themselves, and I'm guessing that since there are two lamps, one in the power controller and one in the cabinet front panel (and that they are not simply wired in parallel or serially) it's something else. Maybe the bulbs are ganged together, I'd better check the FMPS again. Before I dig into that aspect further, I wanted to check in with the group and see if anything stands out that I've overlooked, or if you guys think I should check something else before the bulbs. Just want to make sure the PS is in order before loading the boards into the backplane. Many thanks. - Jared [1] Rescued this unit two years ago this month. Turned out to have an empty card cage, and a fault in the PS. I finally traced the PS trouble to two of the four power output diodes in the 5V supply (shorted out, replaced all four), and a poorly contacting connector in the 2.5V supply. Over time I have scrounged up a complete boardset so I should have a functioning system Real Soon Now.

Options for Installing a TF85 Drive

I was led to believe that a TF series drive might be able to read past a problematic part of a tape I have, and a TF85 has come up on eBay. The problem is that I do not have any DSSI-capable machine and I am not familiar with DSSI. I have a MicroVAX II and it seems I could use a KFQSA, but they seem quite expensive. I also have some VAXstation 3100s and MicroVAX 3100s, which are SCSI. Do I have any other options for installing the TF85? Thanks Rob

Internal company classic computer event

by james＠machineroom.info

Hi all, enough lurking and time to ask a question.... The software company I work for is planning an internal classic computer show as a little light relief near Christmas. We expect a turnout of around 100 people and so far have the following planned: 1) Show as many vinatage systems as possible, ideally working. "vintage" in this context means anything pre-90 as best I can tell but modern rare machine may be shown too. Think ZX81, C64, etc - mostly home machines. I'm personally plannig to show my Transputer collection, though I expect very limited interest :) 2) Have a collection of classic software & games running on emulators "3) retro" music 4) beer and snacks (not vintage) 5) Competitions for high score on classic games and best retro dress! 6) Possibly invite a well known talker or two, depending on how much interest we expect to generate and/or finance. Has anyone helped organise something like this before? is there anything that worked particularly well/failed miserably? This is a small scale fun event and not on the scale of VCF! Many thanks for any advice James

Stockholm PDP-10s

by tshoppa＠wmata.com

Dwight asks: > Is there more? I don't see why that would have put them off doing DECnet. Decnet has some support in some 80's and early 90's era Cisco products... but it was comparatively poor and incomplete compared to what the competition (especially 3Com) was doing. In my opinion (entirely subjective, no real proof), Cisco support for DECNET and related DEC protocols (e.g. LAT) was purposefully made incomplete or done poorly, so that you'd struggle against it a lot with the glimmer of hope that you might figure it out, but you always feel defeated and sore in the end. 3Com's LAT and DECNET terminal servers were really kick-ass, way better than the overpriced DEC equivalent. LAT really is a pretty spiffy protocol for terminal servers. In the end DECNET Phase V (OSI compatibility) was what killed DECNET. Man, what a mess. I feel sorry for the DEC programmers who labored for what must've been man-millenia putting in every possible OSI bell and whistle when in the end nobody ever wanted any of those bells and whistles!

vax - odd thing regarding lego mindstorms.

Hi All, Just something I noticed the other day. A school that I help with radio stuff (yeah I'm a ham) just got a set of the new lego mindstorm bits and pieces. And I noticed their little serial leads seem to use the same almost RJ-12 style connector with the offset clip. I haven't double checked but it seems that someone else is using the connector that I have a battered version. Take Care and 7 3 ~Ivy -- VK3IVY http://radio.carnagevisors.net

I think that the Lego plug has the clip offset to the opposite side compared to the DEC MMJ. So similar...yet even more incompatible! Tim.

Rescued documentation issues

by hachti＠hachti.de

Hello Al, hello everybody! I assume that physical storage capacity limitations are a well known problem to lots of people on this list. I further assume that many of you know situations where they "take everything", "find everything", "buy everything", "rescue everything", or alike. It starts with some information about <anything interesting> sitting <somewhere> at the cost of <price>. The variables differ greatly. In many cases you will cry out "Cool! Don't throw anything away! I'll take all of it!". Of course, all available bits and pieces are at least worth a look. But... This posting is about the "unwanted documentation" you often get with stuff you acquire. I would like to start a discussion on this as I don't always know what to do with it. A clean concept could probably help me and others to maximize preservation of valuable historic information with respect to use of individual storage capacities. The following are three example cases from my "collection career": 1. Honeywell H316 I bought the H316 from someone in Switzerland, on eBay. It came quite complete, with all docs. And some vague oral information about the former application. And a lot of binders documenting the original system the machine was used in. Everything specially made for the application (controlling flight monitor displays in an airport). Everything in Italian. And no actual piece of it left. Still have them. 2. pdp8/l rescue, a few years ago I found my three pdp8/l computers rusting in a garage, not far from here. They were part of an "Olympia Multiplex-80" system used in a bank (someone added one of my pictures of one of the machines to the wikipedia article about pdp8). There were two Ampex 7 track tape drives. And some interfaces to the rest of the Multiplex-80 system. And documentation for much of it. The tape drives were gone too far, so I threw them away (no, there was no realistic chance to restore them: It would have been a complete rebuild! They consisted of rust, rust, and rust). The controllers were also gone very far. So I kept only some pieces of those. Documentation for the tape drive and the whole system is still there. 3. Some Honeywell This last example is not finished yet. And it is the reason for writing this posting. Yesterday I drove up to Denmark. There I met a guy who had sitting around some Honeywell and associated gear that he did not want anymore. What I got were two Level 6 computers and an Ampex Megastore solid state disk for the H316. One megabyte of core memory... That alone was enough to take the trip. And there are two large boxes with paper. I looked throug them, most of them seems to be Accuray (the guy and stuff came from there) documentation for some kind of industrial control system (paper mill, I've been told). Tons of Accuray X16 software listings. Some original Honeywell stuff. Accuray documentation for Accuray software. And docs for a hard disk (fixed head?) disk drive that doesn't exist anymore. All in all, the paper directly related to the stuff that dropped in is less than 25% of the lot. I currently have all of it. Some sitting here upstairs, some in the car, and some in the staircase (the house door is open, it's getting cold). Documentation belonging to collected hardware or software will always be kept. This doesn't need to be discussed. But the rest.... I call it the "other papers". What the hell should one do with this kind of stuff? The "other papers" fall into one of at least three categories: a) Documents generated in equipment's lifetime, closely related to the actual object they come with. Like Service logs, communication with the manufacturer (offers, invoices etc.), personal notes, memory dumps of something that has been used with the system. b) Documentation for stuff and devices (i.e. products) I don't have (anymore/not yet) c) Documentation for individual applications like a paper mill or the airport information system that don't exist anymore. d) Category a stuff that belongs to stuff that did not came with it and which can safely be assumed to have been scrapped long time ago My current practice is to keep category a documents for historic value. They usually don't take much space and are fun to read. Sometimes useful as well. Category b documents are kept if they belong to something I want to have or where I can imagine that I could get it in the future (examples: pdp8/i, straight-8, Honeywell DDP-516). I don't see a reason to keep category c and d documents. I already threw away some of those when they were simply photocopies of (assumed to be) available or completely boring manuals. And I already feel bad about that... So I am drowning in stuff that I don't really want to keep but something holds me from just discarding it. At one point I thought about bulk-scanning those before discarding. That would save the information - and my space. But I currently cannot afford a scanner that can do the job in hours/days instead of months. Al Kossow is doing a great job with bitsavers. I appreciate the approach to share vintage documentation and software in the way he does. I also added a few bits and docs I rescued and scanned. Most stuff on bitsavers is copyrighted in some way. For much of it, the copyright owner can be assumed as not being interested in enforcing the copyright because the information has lost its market value long time ago - or the company simply doesn't exist anymore. But what about stuff marked as confidential? I've got some Honeywell Level 6 manuals (some of them seem to be on bitsavers already), most of them are marked as confidential. Some of them have written "confidential" on every single page... Is it ok to simply publish that stuff? And what about category c documents? Shouldn't they be silently discarded? That would be the "correct" handling as one cannot be sure if parts of the described system are still somewhere in production use. The circumstances under which those docs go their way to collectors' hands are usually of a more or less obscure and inofficial nature... I like to read your opinions on that. Or proposals. I'd very much appreciate a vital discussion. Best wishes, Philipp

Good references for ANSI terminal emulation?

by mbbrutman-cctalk＠brutman.com

I'm struggling trying to create an accurate telnet client with ANSI emulation. The basic codes are easy enough and well documented, but there are a lot of obscure codes to do things like 'set terminal mode' to 'vertical editing mode' which I can't find good descriptions for. I can't even figure out if a pure ANSI terminal supports wrapping to the next line when you hit the edge of the screen, or if that is controlled by an escape sequence. To further confuse things, a lot of people lump the DEC terminals in with discussions of ANSI terminals, and although they are close they are not the same. DEC extended a lot of things. I've been googling, reading source code, and experimenting. It's slow and painful. Does anybody have a good reference they would recommend? Thanks, Mike

Ampex Megastore

by hachti＠hachti.de

Another topic.... I got that Ampex "Megastore 316". It's a ramdisk for the Honeywell H316. Connects via IO but and optionally DMC (kind of data break). Is from the early 80s and contains to times half a megabyte of core memory. Quite a mass... I have some schematics, but not all I would need. Currently it's working a bit - reading only every second word - but that looks good so far. I had to make my own cables. Perhaps I did something wrong...? Played a bit with the controller's microcode. Found no reason why it skis addresses. There must be something wrong with the bus. I have two controllers and two core modules - swapping doesn't change anything.. Does anyone on the list have experience, docs or other information to share? Kind Regards, Philipp :-)

As far as I know, LUDD only have/had a DEC-2020. No -2065 around there. But the largest collection of PDP-10 machines in the world for a long time used to be at Stacken, at the Royal Institute of Technology (KTH) in Sweden. That, in combination with Peter Lothbergs collection. Stacken have had to get rid of most of their stuff, I think, but Peter still has his, and maybe more. Lots of machines from the US were "exported" to Stacken... I know that Peter still have atleast one KI-10 SMP machine (with alteast two cpus) in storage. And that one is runnable. He have KLs as well, and other stuff. Stacken used to have a KA-10 running, and several KL and KS machines as well. I think I've written about this before, but it seems that either is noone seeing my mails, or noone remembers them, or possible noone wants to believe them. Don't know which... Anyway, not that I think you could get Peter to work on restoring a KI-10 unless you have lots of money, but I bet he'd be able to to it in close to no time, without much help. Heck, I know he modified his KI-10 machines to have some extra instruction needed for his modified version of TOPS-10 back in the 80s. If there is anyone in the world who knows PDP-10 machines, it is Peter. It's just that if you haven't been around for a long time, you probably might not know about him. Johnny

Menu builder script for MS-DOS?

by ethan.dicks＠gmail.com

Hi, All, I'm trying to help a friend out with a role-playing game prop, and I have a memory of some tool from a number of years back that can accept a set of scripted menu items and responses and build an MS-DOS BAT script that will "implement" the menu structure. For example - you'd start off with a top level menu with, say, 4 items. Typing 1-4 would take you to one of four sub-menus, etc., until the end "nodes" are reached. The end-nodes could be a launching point for a DOS program (optional), or just a page of informational text. Does this sort of menu generator script ring any bells with anyone? I've googled for three days and have found all sorts of tutorials for how to craft scripted menus (for DOS and UNIX), and I could easily write my own set of menus from scratch in any number of system script languages; the end user in this particular case is not a programmer, so I'm trying to find something that will let him write the informational text for the end-nodes and the menu items to lead to them, but have a tool auto-generate the structure around it. Thanks for any pointers, suggestions or keywords to help my search. -ethan

TU56 lamp replacement

by hachti＠hachti.de

Hi folks, I'm currently checking out some TU56 DECTape drives. Stuck motors, burnt electronics, dirt, and other issues usually come my way. And broken indicator lights. Does anybody have experience replacing those bulbs? Originally there are those white plastic blocks that should be replaced as one piece. Nice idea - I have ONE complete replacement and at least 6 to repair. Those blocks are easily opened, fiddling a new lamp inside is easy and no problem. So what I ask you is only for ideas about the right lamps to use. It should look similar to the original lamps (or could be a bit brighter). Some blasphemy to add: If I don't find a quick solution, I'll fit one of the TU56s with crazy colored LEDs. That might be considered a sacrilege by some people, but it's quite reversible and non-destructive. I have LEDs in two RK05 drives, too (They're soldered to their series resistors and plugged in like the original lamps, so everything can be reverted instantly). The read and write indicators are quite more interesting that way (with incandescent lamps you don't even see many accesses!). But at the moment the question is for incandescent lamps. So please share your ideas/experience with me! Best wishes, Philipp :-)

annoying ebay behavior

by brianlanning＠gmail.com

I had a bid on a laser 128 computer, working complete with power supply. It had been listed in the past for too high a price. This time, the pirce was reasonable though so I bid. There was a second one with a matching external floppy also. I was hoping to make an offer on all of it at the end of the auction. Yesterday, the items disappeared. I guess the seller pulled the items. I wish there were a more sane place to trade this stuff. I guess I have just have to wait for somoene to give up another storage facility. lol thanks for putting up with my venting.

Canon BJC-250 printer problems

by aliensrcooluk＠yahoo.co.uk

Hi, I acquired a 2nd-hand Canon BJC-250 printer back in January. It seemed to work fine, as the test page printed* and Windows 2K SP4 auto-detected the printer when it was switched on (which is good because I got a "data error (cyclic redundancy check)" when trying to copy the drivers from floppy disk to my laptop). On closer inspection though, all doesn't appear to be fine. I thought I had a black only cartridge installed (which came with the printer), but it turns out to be a colour one. Now the problem occurs when I print a page with black text. The text is printed with alternating black and green lines, instead of just black. Now I never saw this problem at work when we used the same printer model, but that may have been a black only cartridge. Is this problem a side effect of having a colour cartridge, bubble jet printers, or indicative of a problem with the read head / cartridge? I have very little experience with printers and would appreciate any pointers anyone can offer. I hope it fits withing the 10 year rule... not sure how old the printer model is. *The test page requires no input from the computer, so I ruled out a possible driver issue. Regards, Andrew B aliensrcooluk at yahoo.co.uk

I certainly agree that the extreme of hoarding everything in one place is the worst possible scenario. I don't even think that hoard is necessarily the word most would use; think of Don Maslin's careful archive of every CP/M boot floppy ever, that was by no means a hoard because he shared it, one piece at a time with whoever needed it, but because it was all concentrated in one place it's now gone. Don and I had talked about hosting disk images etc. but we never got it done in general. But I don't think anyone so far has said that they would hoard it that way. Everyone agrees that PDF's for electronic distribution are a real win. Those who are seriously into it also know: 1. Scanning books without lopping off the spine can make for some pretty crappy scans. 2. After you're done, you gotta do something with the remaining paper. 3. In many (most!) cases the paper is already decaying. 4. There's just such a huge quantity of books, and manuals, and printsets, and they've already decayed some, and they're all gonna decay more. Tim.
