VAX 4000 acting as Webserver ?

by cheri-post＠web.de

Hi all ! Just a question which I'm quite curious about: Is it possible to use my VAX 4000/200 as a web-server ? That way, I could provide my future site about my collection by using parts of it ;) This, of course, would mean the VAX running 24h a day. SCSI-disks would certainly be a better choice than my SDI-disks in order to avoid a crash... Is my VAX with its 5 VUP and 32MB RAM fast enough to run a webserver ?

New acquisitions, looking for stuff

by pat＠computer-refuge.org

Found some "semi-interesting" machines this week: - IBM PC/AT with all IBM components, nearly pristine shape excluding some scratches on the bottom; only missing a couple of screws and the hard drive. It's got the real-deal IBM 5.25" floppy and 3.5" floppy drives (1200KB/DSHD and 720KB/DSDD, right?) - IBM PS/2 Model 90, missing hard drive and RAM, but I should be able to replace those with other parts. I'm hoping to get OS/2 2.1 running on this. And, something a bit more interesting which I actually "paid money" for: - DEC VAX 11/750 with 8MB ram, floating point accelerator, 1kW PCS version of the microcode store card, Massbuss and two Unibus adaptor cards, and the onboard unibus is complete with a TU80K-CP TU80 controller, DMF32 async + printer port card, and DZ11-A serial card. A question about the TU80K-CP: I've heard that it's a DEC re-badged version of a DILOG PERTEC card, with custom firmware so that it only will talk to a TU80. Does anyone have the DILOG firmware that I can put onto it to make it talk to a "standard" PERTEC 9track tape drive? Also, I'm looking for 1) UNIBUS ethernet card - DEUNA or DELUA or similar 2) Different firmware for the TU80K, or a TU80 within a couple hours of here or a different PERTEC card... Actually I might have what I need for the card already..hmm. But I still need to get a drive for it, anyhow. 3) An UNIBUS SMD disk interface and/or ST506 disk interface 4) RL11 interface (RL02/RL01 drive controller) Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

Got a DEC 2000 Alpha server, need help

by TRASH3＠splab.cas.neu.edu

Yes, if you can (and should be able to) get a console prompt, the method I used was to do SET UAFALT 1 CONTINUE which set the authorize file to the alternate, which on our systems did not exist. Then when you enter system as the login id, any password works. I did not know about the method of setting the console to startup, it sounds like another, better way. In my way, you have to play around in sysgen and swap the authorize files around after you get on, but still, any port in a storm. joe heck

A Familiar Face

by classiccmp＠vintage-computer.com

It's always nice to open up the paper and see a familiar face. I was perusing the San Jose Mercury News this morning and came upon a nice article smack-dab in the middle of the front page of the Business section. The article was about Bruce Damer's DigiBarn.

Wire Wrapper needed for PDP-7

by toresbe＠ifi.uio.no

>If I understand you correctly, you are saying that major subsystems were >added to the CPU and wired into the backplane by a former user, who removed >these components without regard to its effect on the operability of the >machine before you came into possession of it. That wouldn't surprise me at >all. Many academic and lab shops did extensive custom modifications, like >the famous BBN paging box on the Tenex KA-10s. No, the Oregon PDP is also barely recognizeable. The PDP-7 was originally meant to be scrapped (was laying around) but it was salvaged by Professor Nordhagen, and ccmaniac librarian Knut Hegna (who has some other minis next to the PDP-7) when the new library building was built in 1987. The last trace of usage I have is 1976. >These machines went through multiple >revisions and field ECOs during their lifetime. There was a set of field >maintenance prints issued for the specific revision that a customer had, >which was then kept up to date with the machine. (At least this is true of >the Straight-8 of similar vintage.) I have three sets of wrap lists. My intention (bad idea?) was to wrap an original PDP-7/A, instead of one with ECOs - and later apply any crucial ECOs I came across. (Al, do you have any?) I could probably cook up some program that would give me schedules based on wire lists (if I am understanding the concept of 'schedule' correctly as something describing the order in which the wires are to be wrapped) The PDP-7 ended up with several ADC's, apparently it had a plotter, an IPB, a 'poor man's API', and so on. Some EE students aparently kept it alive during its last days, but gave up, and returned it to the Good Professor which originally bought it, and let me work on it. He put it in storage, and it's now an exhibit. Funny how PDP-7's tend to turn up vacantly sitting in corners, isn't it...? :) >I can't read a word of Norwegian, but from the pictures, it appears that >Norsk Data >made quite a number of interesting machines from 1967 into recent years. Yes, it was a fairly successful machine. I've heard that the first WWW server at CERN actually was an ND machine, which wouldn't surprise me, given the close cooperation the two institutions enjoyed. (I've heard.) I was yesterday at the Norwegian museum of technology, (I may be working with them on another restoration project - IBM 360/370-ish - but that is entirely in the future and no deals have been made yet - if this is happening, I will of course post immediately to cctech ;)) and amongst some neat exhibits (Jaquard loom, IBM 650 (You should have seen me - crawling down, looking at interiors and drum)) I saw a NORD-1. I don't know much about the machine, but I do know that the one 7 was hooked up to had three 9-tracks, 16k core, but not a very good display - the PDP-7 was later used as something of an intelligent terminal and data-gatherer, hooked up to some (apparently brilliant) Italian ADCs, and letting the NORD-1 do the numbercrunching. The NORD-1 used IC's, and came with a line printer, that's about all I know. I do seem to remember a 16-bit word length, though. The NORD-1 was a commercially successful machine, and earned ND quite a lot of money. I believe it was the NORD-100 which really got ND off to a start - but that's from doubleplusvague memory. I'll get around to translating that page :) Back to the wire-wrapping thing: Is it really that bad? There are admittedly a lot of wires on it, but it doesn't seem all too hard (especially with an electric wrapper!) Am I wrong, and am I not weighing the effort correctly? Is it harder than soldering? The pins are not small, they are about 2mm x 1mm from memory measurement. I thank everyone offering me wrappers! Whew! Thanks for all your help, people :) -tsb

How much does a pair of KDA50 cards worth?

by vax3900＠yahoo.com

I need $40 badly. I am considering selling my KDA50 boards with those internal cables, and a pair of iron covers. Do they worth $40? If not I would like to keep them because without these power consumers my VAX3900 won't boot. Without them the VAX3900 looks less and less like a 3900 though it consists of a bare cage without rack and front door anyway. __________________________________ Do you Yahoo!? Yahoo!

7 track drive located!

by aek＠spies.com

Got a call last week from a local vendor who remembered that I was looking for a 7 track drive. He found two (!) as they were going through their inventory. They are EXACTLY what I have been trying to find for a long, long time.. HP7970 tension arm drives with DUAL MODE 7/9 track head assemblies! They are capable of reading anything from 7trk 200bpi to 9trk 1600 bpi tapes. I won't say how much they were (they weren't cheap) but as part of the deal he let me go through some of his head stack spares, and I found 14 dual mode head stacks! (he let me have five of them with the drives) --al (doing the Snoopy dance right now!)

Interesting NY Times story...

by evan947＠yahoo.com

>>>>> February 1, 2004, Sunday Radio Days or High-Tech, It's All the Same By NEIL GENZLINGER THOSE of you who are still hoping that computers, cellphones, digital cameras and other modern gadgetry are passing fads and that we will soon return to the simpler days of a half-century ago might have been dismayed with what Phil Vourtsis had on display at the David Sarnoff Library the other day. The event was a combination exhibition and radio-repair clinic, with members of the New Jersey Antique Radio Club doing the honors. Mr. Vourtsis, the club's president and the author of ''The Fabulous Victrola 45,'' had a display related to the dear departed 45-r.p.m. record that was fascinating and hilarious, but also depressing. The hilarity came from a 1949 promotional film in which an impossibly earnest fellow was extolling the virtues of this new way to listen to music. ''Distortion-free records!'' he exclaimed. And indestructible. ''Bend 'em, bounce 'em; nothing happens!'' The depressing part was Mr. Vourtsis' sampling of newspaper articles from the period. It turns out the innocent little 45 wasn't so innocent after all; it was part of a war between RCA-Victor (which made many of its breakthroughs at labs in New Jersey) and Columbia for the ears of America. The new 45 from RCA was competing with a seven-inch disc Columbia had just introduced as well as Columbia's LP's, and all were different from older-style records - different speeds, different needles, different players. ''The record-playing public,'' read one account, ''which buys from 200,000,000 to 300,000,000 new disks a year, is faced with three mutually exclusive methods of reproducing music from records. Neither of the two new records can be played on conventional phonographs or radio-phonographs, nor can either be used on competing record-playing machines.'' It sounded, in other words, dismayingly like the technological warfare that bedevils us today: VCR's vs. assorted types of DVD's, CD's vs. MP3's, Windows vs. Macs, attachments that won't open, digital cameras that won't download. Evidently there never really was a simpler time; products have always tried to push one another out of the marketplace, and frustrated consumers have always been left to play catch-up. ''Only today the turnaround on a product is much faster,'' Mr. Vourtsis said. His club (www.njarc.org) has about 200 members, and watching them have fun with antique radios and other ancient technology makes you wonder what people will be doing a few decades hence with old cellphones. (Notice how primitive the ones from the 90's already look?) Lately, for instance, they've been having a contest to see who can pick up the most distant radio signal on a vintage receiver. When conditions are right, noise from Chicago or Canada or Mexico might squawk through the classic sets. At the Sarnoff event, in Princeton, the club's experts ran a repair clinic where people could bring old radios for free doctoring. Some who brought in sick sets were fellow hobbyists, but others were hoping to revive a personal keepsake. A lot of old radios are being unearthed these days in New Jersey and everywhere else as the radio-crazy generation dies off and its offspring inherit attics full of stuff. Mr. Vourtsis said that at first the repair clinics were just for club members, but then it seemed there might be laymen out there in need of vacuum-tube and soldering-gun assistance. ''It's pretty rewarding when we're able to help them out because they feel like they've reconnected with something from their childhood,'' he said. Certain radios can be worth thousands of dollars, he said, though many more models were just as mass-produced as anything today and are worth less than a first-generation digital camera. Also, some antique sets might prefer to remain idle. For instance, someone once brought in an Emerson Catalin that gave Mr. Vourtsis pause. ''It was the kind of thing where I really didn't want to get the radio working again because heat from the radio could damage the cabinet,'' he said, ''and with the Catalin that's where the value is.'' One other booth from the Sarnoff event is worth mentioning, what with Valentine's Day not far off. It was a display of valentines, sheet music and such with radio themes, from the days when radio was new. ''There's a Wireless Station Down in My Heart,'' was one song title. A card read, ''Over the radio you can hear me pine, I want you for my Valentine.'' Apparently, linking romantic sentiments to the high-tech device of the moment gives them extra credibility. So here's an assignment for the season: Use the words iPod, memory stick, mini-DVD and MP3 in a love poem. Give it to your sweetie. Then duck.

NEC Board question

by jpl15＠panix.com

This may or may not be close to the ten-year rule - but anyway: I am having a NEC Pent II computer, very fancy dark blue/charcoal case with a curved front panel running in guides that slides up and down, and the LCD status display, CDROM and Floppy drives all in a removable 'pod' that clips to the op front of the case. This attaches with a connector that is the same as is used nowadays for a SCSI II cable. And there is a similar connector on the card that drives all this stuff (the pod is conneccted thru a ribbon/header) the motherboard has the usual IDE ports and this particular machine boots and runs. It runs Win98, soon to be transmogrified into some dialect of Linux. The only readable info on the card is: Packard Bell NEC (Lo! how the MIghty have fallen!) PB-IRISA-Rev:D PB-0081-1 So I'm wondering if anyone might know the specifics of this, and especially if it is indeed SCSI, or just a case of connector mix-up. Thanks! Cheers John

FYI

by vcf＠siconic.com

I finally implemented SpamAssassin on VCF e-mail accounts after trialing it with a personal account for about a month. I've gone from something like 200+ spams a day to almost none. My personal account has done similarly well though after a while the spam count started creeping back up, but its still at a very manageable level. Instead of having to wade through hundreds of spams every 2-3 days when I would check that account, it's now maybe 10-15. Question: has anyone been able to make SpamAssassin be "perfect" (i.e. no spam at all)? Anyway, the reason for this message, other than to claim (for now) victory against spam, is to let people know that if they do have trouble contacting me for some reason, it may be because SpamAssassin is equating your message with spam. If so, please page me here in the mailing list or you can send me a message via the VCF contact page: http://www.vintage.org/contact.php I LOVE SPAMASSASSIN!!! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Pretty good collection of computers for sale

The parent site seems interesting as well: Japanese Computer Emulation Centre http://www.jcec.co.uk The home page has a link to the seller's eBay auctions (which is invalid, so do a search on seller "j0nstringer") and it looks like he's been selling off quite a bit of classic micro stuff for the past several months. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

box o'ISDN

by brad＠heeltoe.com

This is not really vintage, but I have a box of ISDN "stuff" I'd like to get rid of. I post here in case anyone is interested. An nice TA (adtran), several ascend pipe-50's (2-3), cables, a clam, an NT-1, and an old 56k router box from Imatek. I'll willing to give it away (paypal postage, etc..). but just in case, I'd love to find any sort of unibus floppy interface, broken or otherwise. And unibus bus grant cards - could use a few of those :-) can't hurt to ask. (and if you have a spare 11/73... heh :-) -brad

Wire Wrapper needed for PDP-7

by toresbe＠ifi.uio.no

Hello! I sent an email about a month or two back to Al Kossow saying that I was starting work on the PDP-7 again. With ungodly timing I proceeded to come down with the flu, travel abroad, and move. So here I am again. ;) I have come to the conclusion after some wire-tracing and so on, that this machine is smoking crack, and that very little is where it should be (except for core memory, everything seems right there). The processor has been modified ad nauseum, of course without documentation of any kind. Therefore, I need to take out all the modules, all the wires, and start afresh (might be a good idea, anyway - - this way I can clean all the contacts properly). Thus, I need a wire-wrapping tool. Does anyone here have one? TIA -tsb

Old PC video multimedia hardware (free)

by wmaddox＠pacbell.net

MediaVision Pro Movie Spectrum (ca. 1992-1993) ISA video capture and display card. Includes Microsoft Video for Windows 1.0 w/manual and Macromedia Action 2.5 Looks like the card was never used, but the software and box show some wear. Sigma Designs REALmagic Rave VLB graphics accelerator with MPEG playback hardware. Also have another S.D. card with no documentation that looks like the ISA version of the above. This stuff was dumped on me by a neighbor who is moving -- literally showed up on my doorstep. Free for the cost of shipping to anyone who wants it, otherwise, it goes to the recycler. --Bill

DOS 3.x, etc.

by marvin＠rain.org

My BIL is getting rid of some older stuff, and has about 20 copies of DOS 3.x. Anyone interested? Also, we about half filled up a dumpster with old mono, cga, ega, vga monitors and printers, along with some other ... stuff. Hardly a dent in all the stuff here, but at least it is a start :). There is still about 1/3 of the space left in the dumpster and the project for the next day is to fill it! I found several Wang monitors, another NS Horizon, more IBM mono, CGA, and PGA monitors, some NIB TI floppy disks, bunches of PC cards, another ADM3, and a bunch of other stuff I hadn't seen in a while. This actually gets to be fun seeing this stuff again ... almost like finding it out in the wild :).

But I have no choice. The processor was modified with an improvised API, and half of this was later removed (leaving the processor useless) Also, an IPB (Inter-Processor Buffer) was made, which connected it to a NORD-1, a not-quite-mini, not-quite-mainframe machine. This has also, of course, been removed. The CPU and IO planes, are, in short, FUBAR. I have complete documentation of the wires, and of module locations, they are all documented clearly in F-77 Maintenance Manual (which you have on your site). They are easy to read, and give a complete schematic of both the backplane, and the module locations. There is 0% chance as is. -tsb

FF: Philips Wordprocessor (UK)

by julesrichardsonuk＠yahoo.co.uk

Another oddity at the computer museum at Bletchley which I unfortunately didn't get much chance to look over (if there is interest I'll get better details later in the week). It's a Philips machine with twin 8" floppy drives - I'm told a dedicated wordprocessor, but I'm wondering if it isn't a full-blown CP/M system. Looks to be circa 1980 anyway. As with the IBM, we need the space in the museum, so it's into storage for it, or ask and see if anyone wants to give it a home. Comes with a terminal (I need to check and see if it's a full-blown Philips terminal or just a custom console for the main system box), Philips printer, and a whole pile of floppy disks. No idea of working state on this one; powering up without a boot disk gave a screen full of z's, so there's some basic functionality working at least... Anyone interested in giving it a home? cheers Jules

Catweasel Experts out there???

by tim＠tim-mann.org

Jim Battle writes: > Hard sectored disks are a problem for the catweasel to write. There is > a function to write from index mark to index mark, except the catweasel > assumes there is just a single index mark per revolution. I haven't written code to do this, but the approach I would take is to align with the sector holes by hand: Spin reading from the input port that returns the hole sensor's status, then give the "start writing immediately" command when you see a hole, and write one sector's worth of data. Then spin waiting for another sector hole and write another sector's worth, etc. You might find that you miss a hole each time and need two revolutions to write the whole track. One reason I suggest this is that it seems like there is yet another reason why the Catweasel's built-in hole-to-hole write isn't suitable. Don't hard-sectored disks have an index hole for the whole track that is about halfway between two of the sector holes? If your disks have that, you'd be unable to write that sector with a hard hole-to-hole Catweasel write -- it would stop halfway through. Still assuming this is true, you could find the track index hole by spinning watching for sector holes and noting the time between each two. When you find two that are too close together, you've found the track index hole. I suppose you might have to do all this in DOS to ensure you don't get interrupts that you don't want and that mess up your timing. I'm not sure disabling interrupts is necessary, though. You also could use Linux, as you can do a Linux iopl system call that gives a user process high enough privileges to read/write I/O ports *and* even disable interrupts if needed. I don't know enough about how hard sectored FDCs work to know if there are problems with this approach... -- Tim Mann tim(a)tim-mann.org http://tim-mann.org/

FS/FT: big lot of DEC/PDP/VAX handbooks and manuals

by mrbill＠mrbill.net

Hey everyone, I've got a huge lot of DEC PDP/VAX/etc handbooks and manuals that I need to move out now that I'm concentrating primarily on newer Apple and Sun stuff. This is what I've got left after cleaning out the garage and discarding other manuals that I'm sure other people have already archived or have made available online. Everything is in good shape (considering its age) and none of the books have water damage. One of them (the '73-74 peripherals handbook) has a torn-off cover, but I can fix that with tape. As a bonus, I'll throw in a maroon/purple DEC rack header panel. I'd prefer to keep all this as one big lot, but I might "part it out" if I get a good enough offer. Would like to sell, or trade for useful equipment (x86 systems, older Cisco switches or PIX boxes, Mac systems that will (natively) run OS X, or just make an offer of something interesting).

Yes, sorry. I did in fact repost and that showed up in an earlier digest than my messed up post. When I saw the first one I was hoping something had filtered out the long one, but apparently it was only delayed. Anyway, I went to fix the subject before I had written the reply (since I read the digest, and my email client doesn't break them up, so the default subject would be worthless), and somehow slipped and sent it instead of getting back to edit the message text.

FF: IBM S/36 5362 system (Milton Keynes, UK)

by julesrichardsonuk＠yahoo.co.uk

Hi all, Bletchley Park's computer museum has a working IBM S/36 5362 machine going spare - it's been on display (unpowered) in the museum for a while but we need the space for another machine. It could go back into storage, but it's not the sort of thing that's particularly interesting as an exhibit even when it's running, so even if the space were available for display still, it'd probably be way down on the list of desirable things to have in the main room for the public to see. Hence the asking here if anyone wants it. It was running last time anyone powered it up. There's currently a Memorex terminal with it, plus I'm told there are manuals and disks for it (I haven't seen those personally to see exactly how many!) Shout if interested... cheers Jules

list "Archival Options"

by aek＠spies.com

Jay, would you please change "Set date in archive to when the mail is claimed to have been sent, or to the time we resend it?" to "When resent" on the "Archival Options" admin page. This will put the archive in temporal order when viewed "by date"

I'm helping an academic out with some research on early operating ystsems and he is in need of any version (the older the better) of either QDOS or 86-DOS from Seattle Computer Products on 8" floppy. Can anyone help out with this? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

[was] Dec core mem on eBay

by jwstephens＠msm.umr.edu

I recently snagged three 8K core planes for a Cincinatti Milacron Acramatic system, one processor board and a front panel. These are actually boards that were made by CM under license from Microdata corporation and are actually Microdata 800 or 1600 parts. This is due to Ebay and luck of course, but I was glad to add another licensee of Microdata to my collection. If anyone runs across anything from: Cincinatti Millacron Harris (like the semiconductor company, but really a Mini) Basic Four Reynolds and Reynolds ADP Dealer Services (Reality only, not their LEO Boxes) (LEO boxes were PDP 11/23's which someone else is welcome to) Ultimate (not microdata, but on my radar screen, these are Honeywell Level 6's with co processors) Tellogic (phone switches for hotels, etc) Bitek (phone accounting systems) Please let me know. These will all be 1970 thru 1985 or so vintage, and "minicomputer" in size. Jim Stephens

KSR-33 Codebar Reset Bail

by toresbe＠ifi.uio.no

Allrighty, might as well run this question into a separate email for thread neatness (wishful thinking suggests I will get lots of answers for both posts ;)) The KSR-33 TTY prints properly if I reset all the codebars for the typehead. It also sends at least 6 bits correctly to the PDP-7 (I got the IO status panel working). What do I adjust? Please, explain with the fact that I don't know TTY lingo in mind. Thanks! -tsb

SGI GDM-20D11 monitor troubleshooting

by rigdonj＠cfl.rr.com

Does anyone have any experience working on these? This is the third one that I've picked up and they've all been bad. This one worked briefly but now it's doing the same as the other two; no video and both the red power light and yellow light are flashing. I talked to a friend of mine that's used these a lot and also says that they don't last long. FWIW I think this is made by Sony and is also used by SUN. Joe

Pacific 4 memory installation guides

by joel.fox＠sympatico.ca

Hi Bob. This is a shot in the dark:: Google came up with your message offering copies of the Pacific 4 Memory installation guide. (cf. http://www.classiccmp.org/pipermail/cctech/2003-April/013105.html) Is there a chance you might still have them around? Thanks for any help you can offer. Joel Fox Kingston, ON

The controlling parameter in reforming a capacitor is the amount of heat generated. Generate too much and you blow things up. We have to consider two cases: the capacitor is in circuit, or out of circuit. In the latter case, the recommended method of reforming is by applying the forming voltage through a limiting resistor and then letting the capacitor form at voltage over a period of time with the limiting resistor in circuit. As commented above, the current should be monitored, but the critical term is the final leakage current. If it is out of spec, there is nothing you can do... A capacitor manufacturer used to be in town and they had to monitor old stock for mil spec reasons. Their criteria for reforming old stock was a case temp rise of no more than 5 degrees C and the leakage current had to be in spec in less than 10 minutes. An old electrolytic that takes a long time to reform has probably lost electrolyte and should be considered suspect (its ESR is probably miserable and capacitance below spec). The case of in-circuit caps: With a lot of equipment, if you put it in a brown-out condition, you can fry the silicon. Older switchers are notorious for burning up when operated below their minimum voltage for any length of time. In any case, when lighting equipment, the primary concern is the front end caps. If the leakage current is substantial, you will blow the fuse or take out the rectifier (valves don't have this problem). By using a Variac to bring up the voltage over several seconds, you mitigate the surge and allow initial reforming to take place. If things go, you might as well replace the caps. Depending on the power supply, caps down stream will either see the operating voltage and have to "live" or, in the case where the power supply current limits, will pull down the power supply until formed, if . In the case of switchers, they have a tendency to *turn on* if substantially over-rated (hey, remember we have been taught that it's only current that counts ;<)). So all is not cut and dried. You have to know what you are working with... Hey, and I match your 40+ and raise you a few...

I do AC power fault simulation on Telco equipment. Since the tranformers are standard off the shelf units, I thought I would ask an engineer friend. Industrial induction motors use 1000 volt feed from a delt transformer. It comes out 1000 line to line or 577 line to ground. 577 is effectively 600. Most of your wiring and other devices are rated at 600vac. Max

i just found the following message: ------------- Atari Transputer Workstation for sale Ram Meenakshisundaram cctech(a)classiccmp.org Tue Jul 1 08:54:30 2003 * Previous message: New here... Looking for PDP 11 / RSTS help * Next message: Atari Transputer Workstation for sale * Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi, I know a source for a complete ATW800 in the UK area if anyone is interested. They are asking 250 UKP for it (Cambridge area). Let me know, condition is untested. I wish I could go for it, but since I am across the pond, it is just too costly :-( Cheers, Ram -------------- do you know if this computer is still available for sale? thanks. michael

Old Nixdorf printer

by Martin.Kukac＠seznam.cz

Hi everybody. Today I got "classic" printer made by Nixdorf company. It's old matrix printer, made before 1990 (because of Made in W. Germany sign and since 1990 there is no W. Germany). It seems to be serial printer (it has about 20m long cable, i think no paralel interface can operate such long distances), but it has non-standard DIN 6-pin connector (only 5pins present) market as SAS IN on the printer. I have no idea about type of the printer (there is only NIXDORF COMPUTERS label and then Nixdorf STAD ND45 on small label at the bottom). I'd like to connect it to standard PC. Does anyone have pin-out of this connector or does anyone know something about this printer ? thanks, Martin Kukac, Czech Republic ____________________________________________________________ ADSL za korunu od Contactelu - nejp??jemn?j??

stuff noticed at surplus in st. louis

by jwest＠classiccmp.org

A couple of PowerMac 5260/100 machines, condition unknown (forgive me if this is too recent for the list, I know nothing about them as to age). They recently got in a HUGE shipment of old tubes.. all different sizes... some pretty odd looking ones too. Anyone want me to look for a particular one? Jay West
