Does anyone know of a good internet search engine? I've been using Google but they have gotten LOUSY in the last couple of months since they've decided to sell the "right" to companies to be first in their search results. It's gotten so bad that I can no longer find anything with their searchs except ads for totally unrelated items. Joe

running 3 phase motors from single phase...

by julesrichardsonuk＠yahoo.co.uk

Rats, I just found out the museum's dead Sperry drum store uses a 3 phase motor - is there any way I can run this from a single phase supply (UK mains, ~240V, 50Hz) without things blowing up? Or am I resigned to replacing the motor with a single phase equivalent? I just want to get the thing spinning so that people can hear it running - it's way beyond actually being able to restore it to working condition again :-( cheers Jules

I've got an adaptor but since there's a DEC rack right behind me as I sit at the bench, and the room is small, I rarely need to plug anything in at the back of a DEC rack. Anyway, the adjacent rack has a 13A rackmount power on it, and there are several 13A sockets on the wall behind the other racks (three racks in total). > Although I don't do much heavy metalwork on my electronics bench, I agree > a small vice is very useful.

The vice in question is too small and light for crimping connectors. I just use it for holding D-connectors, or holding multicore cables when I tin the ends. But the adjacent bench has a proper engineer's vice (a Record No.3), and there's a 3" vice on a Workmate at the other end of the room (all of 4 metres away). -- Peter Turnbull <postmaster(a)dunnington.u-net.com>

SNMP management

by lists＠microvax.org

Hey guys Did DEC ever produce SNMP management software for Windows? I'm drawing a blank on 'managing' my DEChub90 as [the GPL software i've got for Linux doesn't have the right MIBs loaded/I don't understand SNMP very much at all] - and I was thinking that DEC's own software would make it easier. Any links, or recommendations for a Windows/Linux/Java SNMP browser? alex/melt

I have just got an apollo 735 (couldn't resist it for 9 pound on ebay). It has 96mb ram, 2 1gb hard drives, a framebuffer with a stereo +rgb ports and what I think is a 99mhz processor. All is looking good except it has no power supply. Anyone know where I can get such a beast. It looks quite big if it fills up the mising hole, the machine already weighs a ton it must be pretty heavy with it in. Thanks Dan

WD1793 read-track weirdness

by yakowenk＠yahoo.com

Hey all, Has anybody out there written drivers for the WD1793 floppy disk controller chip? I've been doing that for fun, and have hit on a very strange problem with the 'read track' command. It seems to work just fine, returning a stream of bytes that includes the data for each sector, until it finds a byte with a value of $29 (or 29H, if you prefer). From that point up to the next address mark, it gets garbled data. No other data value seems to have any odd effect. 'Read sector' returns the right data with no weirdness. It is extremely consistent; using read-sector and write-sector, I can add/move/remove bytes with that value, and get the same result every time: read-track returns garbled from the $29 up to the next address mark. At first I thought it was just losing synchronization, because the address mark (at which it synchronizes) puts it back on track. But the garbling seems weirder than just out-of-sync. After the $29 byte, it seems to be OR-ing the byte with itself shifted right one bit, and then inverting that. More precisely, it seems to be doing something like this (in 'C' notation): found_29 = 0; while ( /* whatever */ ) { input = get_input(); // input from disk if ( got_address_mark() ) found_29 = 0; if (found_29) { carry = (prev_input & 1) << 7; output( ~ ( input | carry | (input>>1) ) ); } else if (input == 0x29) { found_29 = 1; output( 0x14 ); continue; } else { output( input ); } prev_input = input; } In case it's relevant, it is a Radio Shack Color Computer 2, with a standard controller cartridge. (The label has wandered off, so I'm not sure whether it is the older or newer model of controller.) I don't suppose anyone would care to venture an explanation? Anyone? Anyone? ....

Rescued Heathkit OM-3 Oscilloscope

by classiccmp＠vintage-computer.com

I was out driving today and noticed a pile of stuff sitting under a "Free" sign. One of the items caught my eye because of the dials, knobs and round screen on the front. It turned out to be a Heathkit OM-3 Oscilloscope (1958 vintage according to my limited Googling - which DID turn up relevant results.) It's missing a couple of the plastic caps to the banana jacks on the front, but is otherwise complete. I powered it up and it seems to work (An adjustable horizontal line appears on the CRT, anyway.) Not bad for a street corner find. So, does anyone have any info; docs or otherwise? Erik Klein www.vintage-computer.com www.vintage-computer.com/vcforum The Vintage Computer Forum

Then connect the single phase wires as one of the phases and cross connect the other phases. This uses the free spinning motor as a generator for the motor with the load. The motor would need to be an induction type. Of course, one could have another motor to spin up the generator and a simple control to switch over the power once it is spun up. Dwight

running 3 phase motors from single phase...

by trash3＠splab.cas.neu.edu

there are more than a couple of ways to do the conversion. 1) use a solid state 3 phase "inverter". Not my best choice, as they are usually expensive and a little fragile. 2) get a 3 phase alternator, connect to single phase motor, making an MG set (motor-generator). straight forward, but 3 phase alternators are a little expensive also. 3) Use a 3 phase motor with a special starting circuit to create the third phase. This is what I normally use. the third phase is a little weak, but it works well. What happens is that you take a 3 phase motor bigger than what you want to power (for instance, if you have a 1 hp disk drive, then a 2+ hp motor is required for the "convertor"), and use a starting capacitor and relay to feed the third leg until the motor comes up to speed. ( the "mains" go across two of the three input leads, and the capacitor/relay third wire goes to the last input lead). Then, once the motor is spinning, you can connect your "load" up to the three leads of the "convertor" and you get a reasonable 3 phase supply. joe heck

Problem with ESDI drive

by fire＠dls.net

Dear Classic Computing Community, I goofed when I was transferring data from a Compaq Deskpro 286 to my modern machine via 1.2MB 5.25" floppy. Machine was difficult to boot due to problems with config.sys and autoexec.bat. This time instead of booting from DOS 4.0.1 floppy, I boot from startup program floppy which helpfully offered to fix problems accessing hard drive. I was tired enough that I did not realize that this meant it was offering to repartition and format hard drive. OK. Data is all still there because I have not done anything else to it. I tried to run some of my utilities on the Compaq, but they did not like the fact that the machine has only 8MB of memory. I would like to take card and drive and install them in a more modern 75MHz Pentium system which has an ISA slot. When I put card and drive in Pentium it will not boot. It counts memory and freezes. I have tried a number of ways to configure the dip switches and play with the setup program on this machine. Machine is a Packard Bell 401CD Here are the specs: Core CNT-HCR controller, I have the manual. Here is a web page with most of the information : http://www.embeddedlogic.com/TH99/c/C-D/20256.htm Core HC150HD, here are specs I found for this drive: http://members.tripod.com/~oldboard/assembly/hard_disks_drives.html http://www.powernet.co.za/info/tables/disk/hdd/Other.Htm I also have Core Tape drive which has backups of all files if I could get drive to work - I do not have software/drivers for any of this hardware, but somehow I have the manuals, so I know the names of all the commands. I found some settings in the Setup in the Packard Bell for shared memory for the ISA card, and address and interrupt settings. I set them appropriately. I suspect that it might be something like the ROM on the card interfering with the ROM on the machine. This drive did something like overwriting BIOS in memory while machine is booting. Or maybe I completely misunderstand what is happening. Anyhow I would like to at least figure out how to get card in newer machine even if I cannot figure out how to get data off. I might eventually end up sending it to DriveSavers. Very good people, and I don't mind paying them, but I would like to see if I can get the partition table right and unformat to run. That should be all this drive needs. Bradley Slavik

IBM and SIEMENS - Gear. Please Help to identify...

by Wolfgang.Eichberger＠bps.at

Dear Classic Computing Community, I'm on this list for quite a while an enjoy reading very much. As long I have room for I'm collecting a bit myself. Some time ago I came in touch with our local museum. They collected some stuff an put it in their storage years ago. They eventually put the machines on display in future. The storage had moved to another building and most of the information about the systems in storage has been lost. In the last weeks i tried to identify most of the bigger stuff, but now I'm stuck. It seems that there are a couple IBM-Systems, but I'm not familiar with IBM. As long I found out: There is an 1131 CPU and a 1403 Printer - I think this machine (CPU and Printer) is rather complete. I contacted the guys at ibm1130.org last week, they are very nice and helpful! Does anybody know what power connection would be needed to fire this one up? With _lots_ of cleaning and some repair work it should be in working order... Then we have a Pile of various IBM-Stuff, which I cannot determine which belongs together. I hope you can help out a bit - I'll list the stuff below: 2319-Disk Storage 2821-Control Unit 3047-Power Unit - I couln't find anything on this box... 3145-Processing Unit - This should be a Sys/370 Model 145, as far I found out... 3215-Console - Maybe for the 3145? 3330-Disk, 3 Cabinets. 3741-Data Station. Like the one seen on http://fwtunesco.org/musi/wolz/ but with only one drive. 3830-Storage Control - Disk? I have no details on this. Suggestions? 5415-Processing Unit - System 3 Model 15 is all I know... 5445-??? It should be some sort of Mass Storage Controller... One Dual Drive for - I think - Disk Stacks/Packs, It is a top loading device, like 2 washing machines side by side... - I couldn't read the number as it's near the wall and I could not move it. There is another Diskdrive too, wich seems to be like the 3330, but some different... All I could do is to list the devices. As I have 2 CPU's I think there are 2 Systems. Any suggestions? There is some Siemens Stuff too... One System 300/320 Processor Cabinet with 2 additional Racks. A System 300-R10 Processor Rack. The machines look like 16-Bit, with nice blinkenlights and flipswitches. A papertape-reader/punch and a dual 9(?)-track drive (on this drive there are still 2 tapes loaded - One is labeled System) are the only peripherals i have. I really want to get the tape off the drive to a) read it or b) store it in adequate environment. Is there some information present about siemens stuff? I googled for a while, but there was nothing really statisfying info out there... In Addition to all above we have a "Data 100 Batch Terminal" wich seems to be a card reader/punch. Does somebody know them? Some Documentation should be here, but as with all the docs I couldn't dig through all the binders and boxes ... Please excuse my horrible english, but I hope you could imagine what has been meant :) My best Regards, Wolfgang Eichberger PS.: For my private Interests I am looking for a PDP 11/23 maybe with one or two RL02 drives, if somebody knows some sources. It could be a different processor or a nice microvax as well :) ======================================================================= Wolfgang Eichberger?????????????????? phone: +43-732-7720-12655 ????????????????????????????????????? cell.: +43-664-240-65-92 Qualit?tsmanager, EDV - Koordinator?? fax? : +43-732-7720-12918 ????????????????????????????????????? email: wolfgang.eichberger(a)bps.at ----------------------------------------------------------------------- O?.

Diagnostic Box?

by marvin＠rain.org

At the TRW swap meet yesterday, I ran across this box: http://www.rain.org/~marvin/box.jpg. The reason I bought it was that the overlays had some words that rang of old mainframe computers. There are three double sided overlays to define what the LEDs mean with designations such as "Print Scan Counter", "Print Character Generator", etc. Another overlay has the heading "2314/2841 TROS SAL BITS". There are two rectangular connectors with cables to connect to whatever this thing is doing something with:). The only label on the box says "Infinite Computer". Anyone have any idea what this thing is and is used for?

That sounds not unlike my bench. It's a sensible height for sitting (decide whether you want a chair, a stool, or whatever). It has steel support legs angled in such a way as to support the front of the bench (I can stand on it without qualms) yet not to get in the way of my knees, and still be mostly vertical. Apart from that, it's wooden, and has a mat in the centre so that things don't get scratched. There's a row of 13A power sockets along the back wall in an almost unbroken line (and half a dozen network/structured wiring RJ45 sockets). A couple of them are European Schuko sockets. Some of the sockets are on one breaker, some on another (one set has an RCD, one doesn't). There are a few more mounted under the front edge of the bench. There's a scope on a wall-mount swivel base, a monitor, DVM, and Avo 8 on the bench at one side and an SGI Indy on the other side. The other things like PSUs, signal generator, etc are at the back or on a shelf. There's a striplight-type desklamp to one side, in front of a wall of components drawers, and next to that are a load of hooks for test leads, video cables, etc. Amongst the things that live permanently on the bench top are my soldering iron, and a small vice. Some of the things used for testing live on a trolley nearby, along with a BBC Micro, and the scope can be moved to the trolley if necesary. There's another trolley with a toolbox also nearby. It isn't actually very big (as Jules and one or two other listmembers can testify), in fact it's quite small. Crowded, even. I'll reiterate the last line I preserved from Tony's post. You can never have too many power points. Or RJ45s. -- Peter Turnbull <postmaster(a)dunnington.u-net.com>

Got a IBM 5362 Today (Keys)

by ceby2＠csc.com

Keys -- Sorry I didn't pick this up over the weekend.... Here's what you have: _S/36 Midrange Server_ o Arch: 16bit o CPUs: 1 IO proc x 1 CP prc o Mem: 128k - 2MB o Disk: 20MB - 120MB ( 1 or 2 14" HDD), 1.2MB 8" FDD This was IBM's main midrange offering through the 80s and into the 90s. It was replaced by the AS/400 (which usually has an S/36 compatibility mode available). If you've ever worked with AS/400s, you'll find the system a less feature rich version of much the same thing. What I must emphasize is this is not a PC. Nor is there a BSD / Linux variant for it. This machine has much more in common with s/360 hardware architecture than i386. The data storage is a flat address space. It's organized into libraries, members and files. A typical application relies on a fixed field length data file format, separate sort and query facilities. IBM has invented relational databases, but the were only available on the more exotic S/38. Here were looking at flat datastructures. Generally speaking one programmed this in RPG II language, although there were editions of COBOL , FORTRAN and BASIC available. It's target audience was the same as Novell's. IBM saw the S/36 as the hub of many PCs with 5250 adapter cards. The nodes could share data through the server, use shared printing and data storage, even use an e-mail like messaging system -- and yet they would still have their standalone facilities if required. Once on your System/36, you could explore centrally managed access to mainframes, peer, or hub and spoke arranged hosts of varying kinds. You could could even call in via modem pool from home. Most people don't view IBM offerings as sexy, but this was very straightforward server platform that provided reliability, shared resources and connectivity. A lot of small to medium sized companies powered them up and kept them in service for a decade before moving to a more PC oriented client server platform in the 90s. These critters are still humming away in dusty corners of 3rd world in suprising numbers. So what are you gonna do with it now? The dual processors and their dispatching system haven't peaked the interest of the hobbyist. And the system architecture isn't well documented, at least not in the public domain.That rules out a Linux or BSD variant. You will have to run S/36 on it unless your an assembler god with top notch contacts in an IBM retirement home. That's where this whole thing becomes sticky. Your post indicated you didn't have media or manuals. The first part of the manual conundrum may be easy. Your model -- the middle tier in the range -- had it's hardware manual strapped to the inside of the cover panel. You may already have worked that out in the midst of cleaning the dust out. There are no manuals available in the public realm that I know of. That's where I come in. I have most of the available media and manuals. I have a few things scanned -- although the scans are huge. Media's tricky. There's no IBM hobbyist policy. In theory you still have to buy licenses. So I would suggest you do what I did. Call around the AS/400 houses and watch eBay for any listings of used 8" diskettes with IBM labels. But before you do any of that, see if you can get it running as is. You may not need media. These beasts are tough. The drives don't generally go bad. The first thing you need is a cleaning, some kind of 5250 compatible device plugged into the first workstation port... and lots of luck. I recommend a real green screen. PC emulators have so many possible settings, it's more predictable to plug up a real terminal. If you get to an IPL settings screen we can talk about how to get past security, and what kinds of snags you're likely to find. Regards, Colin Eby

electronics workbench

by jwest＠classiccmp.org

My amount of test equipment has outgrown my workbench setup, so I need to look at setting up or building a bench. I've got the current bench so crowded with gear it's hard to work already, plus I've got a lot of test gear that isn't on the bench and should be. i'd love to get the laptop a spot on the bench too (lots of room it would take up) So.... I went googling in search of pictures of good bench setups. I'm looking for ideas on the best way to stuff as much gear as possible onto it, while keeping it usable and neat. Does anyone have any links to different ideas for workbench setup? I have a sneaky suspicion that if I just build one myself I'll find that later "oh WHY did I put the outlet strip THERE?". I didn't find much of anything googling, but was hoping to draw on experience of others for some ideas in building a bench from scratch. So far I've used those "set on top of a desk premade lettershelfs". They let you put rows of test equipment close with the faces all well accessible. But haven't found the best place to put the power strips. If anyone has links to pictures of bench setups, or advice of things to watch out for when putting one together, I'd like to hear them!

IBM System/36 and Nixdorf 600/45 available

by norm-classiccmp＠docnorm.com

Free to good home: * a full-height Nixdorf rack, labeled 600/45, containing a 9-track capstan-type tape drive and another device that might be a terminal concentrator, or maybe something more interesting -- it does appear to have a floppy disk drive in it, but the cabinet's front door is locked and we didn't try very hard to get inside and look. * an IBM 5362 System/36 CPU, cosmetically OK (well, mostly), but with no software, cabling, terminals, or documentation. Would be a good source of spares for someone who has a 5362. We need this stuff out of our Oakland, CA warehouse space by Wednesday. Interested? E-mail me or call Brian Knittel at 510-559-7930. Thanks! Norm Aleks

Are you per chance using a browser that may not display the paid links on the right or top as different from the rest of the links? Ordinarily, I would think that would be a stretch, but on this list, I know its common to find people using Lynx or some other browser that may not display things they way google planned. its also possible that they company is seeding certain terms in an effort to get pushed higher on google. IIRC, google prioritizes based on who is linked the most... so if the company spams public archived mail lists, or has a banner ad that is being picked up by google, they may be artifically getting moved to the top. -chris <http://www.mythtech.net>

QIC-100 SCSI tape drive?

by brad＠heeltoe.com

Anyone have a QIC-100 SCSI tape drive drive? Or know where to get one? Seems like there was a brief window when such a thing existed, but I can't seem to find any evidence on the web. I must be searching for the wrong thing. I probably need a specific product. I've got a qic-150 drive (the large 4x6x.5" carts). I need a qic-100 drive. (I suspect it's the same size cart as a TU-58. I don't plan to use it to read TU-58's, but who knows, maybe it will read them) -brad

MonroeMatic help

by cswiger＠widomaker.com

Hi Gang - Is there an email support list for mechanical calculators? I just picked up a MonroeMatic, looks like a model CSA-10, for a cheap price in un-molested condition. Tag shows an M.G. date of 982663. Just needs de-gunking cleaning and lube (hopefully). I can get it to do simple add / subtract but things like the 'set up' button aren't obvious. It's one of those jobs with the shifting accumulator along the top, multiplication and division ;) --Chuck

Just thought I'd make everyone aware that I have listed several old (50s and 60s) pieces of test equipment (vacuum tube) on the Vintage Computer Marketplace. They are a Tektronix scope, EICO TV-FM Sweep Signal Generator, EICO TV-FM Sweep Generator & Marker, HP Vacuum Tube Voltmeter, and a HP Audio Oscillator. I am listing them here first to give our members a chance to get them first. I will be putting those items that do not sell up on ebay at a later date and a higher price. Thanks for looking. Bill

tu58 carts for 730 on ebay

by msokolov＠ivan.Harhan.ORG

Brad Parker <brad(a)heeltoe.com> wrote: > Someone's selling tu58 carts (a.k.a. "dectape II") for a 730 on ebay. I have bought them. These are the very same diagnostics I wrote about on this list just a short while ago when discussing poor man's alternatives to AXE for validating new VAX implementations until we can raise enough manpower and firepower to storm into HP headquarters and seize AXE at gunpoint. These diags are not specific to 730, I read about them first in an 8200 manual and they test for correct operation of standard VAX instructions. I understand from the discussion on this list that their coverage is nowhere near as complete as AXE, but it's still a more complete test than just seeing my new VAX boot 4.3BSD-Quasijarus. (For example, UNIX makes absolutely no use of executive or supervisor modes, just kernel and user.) The next challenge will be reading the TU58s. I have the TU58 mechanical units, but not the controller board (the board that talks serial on one side and drives the head coils on the other). So I'll need to find a controller board first before I can read them. When I do read them, I'll post the block images on my FTP site. MS

And more importantly, did any of the 3000's have blinkenlights? :) -- Frank will probably give a much better description when he sees this, but the 3000s built in the 70's had pretty impressive maintenance panels (I know Frank has one of them..) MPE was (is) the only operating system. Languages included BASIC, APL, FORTRAN PASCAL and SPL. There was no assembler. It is a stack machine ala B5xxx series. I have been scanning a LOT of 3000 material (mostly through the Series III) and I'm trying to locate distribution tapes from these machines up through MPE IV (early 80's) >From what I have found so far, there was a lot of documenation from these early 3000s saved, but none of the old software distributions. I'll see about getting some docs/pictures up on bitsavers, which is pretty light on 3000 material right now. -- also, bitsavers moved yesterday to a new machine/ip adr which should be transparent to everybody.

HP 200LX

You will probably have trouble finding a 200LX for $50, though, since for $125 you can get a broken one (even a broken LCD) fixed at Thadeus and working ones are going for $150+ on eBay now. The average prices are down a bit now from a year ago. If you are patient, you can get one for <$150. I paid about $115 for mine a few years ago, when the average price was more like $300.

replacing +15v regulator on BA-11?

by brad＠heeltoe.com

Anyone have experience with the +15v regulator buried deep inside the back of a BA11? (this an 11/34a actually) It appears one let go on me this morning. The symptom initial symptom was no +15/-15v, so I went to my garage and pulled the two supplies from a "spare" BA11. I replaced them and got the -5 and +20 back but no +15. I should have known it would be the supply deepest inside the back of the thing, requiring I completely disconnect the back module. blah. Is it hard to get to and replace? I'm tempted just to swap the back ends of the two BA11's... -brad

UFO over DEC

by msokolov＠ivan.Harhan.ORG

I have just met an ex-DECer in the #ufo channel on the Undernet IRC network who claims to have seen UFOs over DEC. Needless to say, I was extremely intrigued, being both a ufologist and a great DEC fan, and I asked him for more. He told me it was in Colorado Springs around 1993-94. He said he couldn't remember the 3-character DEC facility code, but he said they were working on CD-ROMs there in a clean room when CD-ROMs were state of the art. He said the facility still exists today and has high security. I asked him if it went to HP and he said Quantum. So I immediately thought DLT and asked him if it was the facility where they made DLTs. He said yes. He said he worked on the tape drives himself, as well as on CD-ROMs. Now here are my questions for this list, to verify the story and to fill in missing details. * Were DLTs indeed made in Colorado Springs? DEC's tape business went to Quantum, didn't it? Did it go through Compaq or straight to Quantum from DEC? Does Quantum still own it? Or did HP snarf it from Quantum? I once visited Quantum in 2002 for a job interview (they were looking for someone to write firmware for a RAID array to emulate a tape library) and that was in Irvine, CA on the UCI campus. Is it just the headquarters, with actual DLT tape drive manufacturing in Colorado Springs? * If it is indeed in Colorado Springs, does anyone have any more information on that ex-DEC facility? Does anyone know of any government/CSS work done there? * This guy also mentioned CD-ROMs. He said they made the first DEC CD-ROMs there, in 1993-94 timeframe. I thought the first CD-ROM sold by DEC was RRD40 and was actually a Philips drive, wasn't it? The next was RRD42, which was actually made by Sony, right? Did DEC ever build CD-ROM drives themselves or did they all outsourced to Sony and such? If RRD40 and RRD42 were Philips/Sony, why did they need a clean room in Colorado Springs? Or was it the next one, RRD43? Was RRD43 also Sony or was it made by DEC itself? What was DEC's cutting edge CD-ROM drive in 1993-94? Did they make any CD-ROM drives at the same place where they made DLTs? It kinda makes sense that it would be the same group, "Tape and Optical Products" if I'm not mistaken, but just checking. Here are the relevant parts of my conversation with this guy from my IRC log: <VortexQ:#ufo> there were about 50 people that saw this on a clear blue day...during lunch <VortexQ:#ufo> <VortexQ> to everyone's surprise...we all looked up and a huge cigar-shaped UFO was hovering over the building at about 200 feet overhead <VortexQ:#ufo> <VortexQ> right over Digital <VortexQ:#ufo> it was very apparent that there seems to be a vested interesting from a higher source, in DEC <VortexQ:#ufo> interest, that is #ufo> VortexQ you still didn't say which DEC facility/group and when did it happen <RB2:#ufo> Msokolov> Colorado Springs #ufo> RB2 what do you mean? You mean DEC facility in Colorado Springs? #ufo> what time period? how long ago was it? <RB2:#ufo> That's what I understood from Vortex <RB2:#ufo> I have no idea, he didn't get to that yet :) #ufo> did he tell you what was his job at DEC? <RB2:#ufo> No, I didn't get anymore information than that. #ufo> I still wonder when did it happen #ufo> RB2 said it was in Colorado Springs, wasn't it? Can you tell me the DEC facility code? I know each DEC facility has a 3-letter code <VortexQ:#ufo> F***...what is the code? <VortexQ:#ufo> hmmm <VortexQ:#ufo> it has been a while #ufo> did you actually work at DEC? <VortexQ:#ufo> yes <VortexQ:#ufo> doi <VortexQ:#ufo> like people remember the stupid facility code for the rest of their lives...sheesh! <VortexQ:#ufo> I do not work there anymore <VortexQ:#ufo> duh #ufo> how long ago was it? <VortexQ:#ufo> well, hell <VortexQ:#ufo> they were working on cd roms in the clean rooms at the time #ufo> their computer technology was so marvelous that even aliens got interested! <VortexQ:#ufo> cd roms were fairly cutting edge back then <VortexQ:#ufo> I think the aliens were more interested in the research they had going on in the basement...Msokolov <VortexQ:#ufo> 1993-1994...somewhere around that time #ufo> thanks VortexQ, that's a much better date #ufo> more precise than "when making CD-ROMs" <VortexQ:#ufo> well, I have the flu...Msokolov...my thinking is a bit slow between tissues #ufo> VortexQ, I know the feeling, I hate flu too <VortexQ:#ufo> in fact...strange that you meantion them being shut down #ufo> why strange? <VortexQ:#ufo> I do not really believe they are...Mskovolov #ufo> well DEC was torn to bits and sold off to various nuts like Comfuq/HP #ufo> VAX was killed and buried <VortexQ:#ufo> after the craft started showing up...the whole facility seems to be very off limits secure now <VortexQ:#ufo> yeah...true #ufo> does it belong to HP now? that facility you worked in <VortexQ:#ufo> yes, I believe so...Quantum had it #ufo> so it didn't go with the rest of Digital to Compaq? It went to Quantum instead? #ufo> VortexQ, was it the facility where they made DLT tapes? #ufo> I know that part went to Quantum <VortexQ:#ufo> yes, Msokolov...why? <Shambuku:#ufo> Vortex do you have a degree ? <VortexQ:#ufo> no, I do not have a degree <VortexQ:#ufo> why? #ufo> I'm tracking it down, this may be of extreme importance to humanity <VortexQ:#ufo> is it necessary in order to be intelligent? <Shambuku:#ufo> Then how did you get a job at DEC <Shambuku:#ufo> Yes #ufo> you don't need a degree to be intelligent <Shambuku:#ufo> Yes you do #ufo> only to satisfy the assholes in HR department <VortexQ:#ufo> I have a year in electronics in college <VortexQ:#ufo> you could say I learn very quickly <nwb:#ufo> did einstein have a degree <VortexQ:#ufo> lol <Shambuku:#ufo> Yes <VortexQ:#ufo> about that too Msokolov <VortexQ:#ufo> I worked on the tape drives...I also worked in the clean room on cd rom drives...the very first ones going out #ufo> what CD-ROM drive was that? I thought both RRD40 and RRD42 were built outside and only badged by DEC <VortexQ:#ufo> the tape drives are used to backup data on the system...used as a backup for the server data #ufo> I know of course what tape drives are for #ufo> I'm a real geek of BIG computers, still run VAXen <VortexQ:#ufo> I have also worked as a computer operator in a computer room at a hospital...doing backups and monitoring of the servers and also micro fiche #ufo> cool #ufo> but still, what CD-ROM was it that they were building themselves in a clean room? #ufo> I thought RRD40 was Philips and RRD42 was Sony <VortexQ:#ufo> guess what, they left me all by myself and I had no problem at all handling the entire list of tasks <VortexQ:#ufo> the manager just hands me the list...shows me around and says...can you handle it? I said yes. #ufo> so what was the first CD-ROM drive built inside DEC itself? Was it RRD43? Or am I missing something? <VortexQ:#ufo> and I did it <VortexQ:#ufo> hell, I would have to dig out boxes for that information at this point <VortexQ:#ufo> I am more interested in holographic computer systems and crystalline data crystals at this point in time <VortexQ:#ufo> you'd be surprised what things are going on now That's all I have gleaned from this guy. I don't expect much help from this list with the UFO part, but at least I'm hoping someone can chime in on the parts having to do with the history of DEC and whatever Classic computing technology they were working on that was so marvelous that even the aliens got interested in it. MS P.S. A more complete IRC log is available on request.

Is anyone familar with HP-IB disk drives made by IEM?

by rigdonj＠cfl.rr.com

I went by a surplus store today and found two interesting disk drives made by IEM of Ft. Collins, Co. The first drive is a Series 5300 (model 5365) and appears to be an MO drive. It has a HP-IB interface. The second drive is a series 6000 (model 6050). It has four drive indicator lights on the front so it may have four fixed drives in it. There's also an LCD display on the front and three buttons labeled "Prev", "Select", "Next". It appears to have both a HP-IB interface and a SCSI interface! Does anyone know anything about these drives or what media the first one uses or what the dip switchs on them do? I searched the net for IEM and found plenty of references to them but the link to their site is dead. The links referred to them as a thrid party supplier of HP drives but didn't give any details.

automake,autoconf,libtool folks here?

by jwest＠classiccmp.org

It's sort of on-topic because it relates to HPEMU :) I've run into a few snags when trying to GNU-ize HPEMU. Specifically my lack of knowledge revolves around dynamic (dlopen-able) libraries. I've googled and read info pages and I'm still missing something. I know how to do what I want by directly calling ld and it works fine, but I don't see exactly how to make that fit into the GNU way of doing things. If anyone is up on autoconf & friends and can offer some advice, please contact me off-list! Thanks in advance, Jay West --- [This E-mail scanned for viruses by Declude Virus]

OT? Apple Stylewriter problems (update)

by mtapley＠swri.edu

All, Round Tuits are in short supply around here. However my wife (after *two years* of patiently waiting) finally started shopping for printers, motivating me (it's not the money, it's the pride) to finish the repair I'd started on the Apple Stylewriter I was whining about on the list in January 2002. Success! I dug out the packet of 2SB1243 transistors (thanks Pete Turnbull for specs and identification) that arrived in the mail a few days after motivation disappeared in 2002, tested them to make sure the Base was the same place on the new package style (not the same beveled edge square package as the originals) as it was on the old package style (thanks Tony D. for telling how to test with analog VOM), and soldered them in. Put everything back together (thanks JPero, Toth, and Matt for help there and suggestions on other things to check) and plugged in the new (replaces the one I fried while testing - thanks Saint Don Maslin) power supply. No response. Changed to the other Stylewriter (won't print, but powers up) that I got from Electronics Plus (thanks Cindy Croxton). Powered up, didn't print. Changed back. The original one powered up and printed! The power supply connector is grungy, need to clean it, but otherwise the unit appears functional! That implies that the power transistor was indeed the problem all along. Main point of this message is to offer sincere gratitude to all the folks that helped me along the way! Secondarily, if anyone has the same fault (missing line of dots in the printed output from a Stylewriter), I'll be happy to pass along my experience, FWIW. Tertiarily, I'm angling for the honor of the longest (chronologically) continued thread on the list ;-). -- - Mark 210-522-6025, page 888-733-0967

Bloody newbies

by cb＠mythtech.net

>Do you think people misconstrued the model number as the serial number? The >seller didn't mention that some of these early ones were signed by Jobs and >Woz. Or is that myth? I don't know about Jobs and Woz signing early ones. In fact, I tend to doubt it is true, as to the best of my knowledge, Woz had nothing to do with the 128k. (There are IIgs machines with Woz's signature) ALL early macs have the development team's signatures inside the case. Jobs is among those, but I do not believe Woz's is there (I'm not 100% sure). I regularly see people trying to play up the signatures inside the case as some rare thing that is worth money. In fact, what might be worth money, is a case that truely had NO signatures inside it, because those don't appear to exist (not counting those that the mold did a poor job of reproducing the sigs, I have one like that, the sigs are very hard to see, but they are still there). And going back to the ebay auction, it strikes me as REALLY REALLY high to pay $411 pounds for a 128k with no documentation or softare, cracks in the floppy case, a broken/sticky keyboard, and not fully tested. -chris <http://www.mythtech.net>

Electronic components sources

by classiccmp＠vintage-computer.com

I'm looking for two items to get a couple of machines back in operation. First, I have a Heathkit H-17 drive with a broken fuse holder (the black plastic tube with the red button on the end) that I'd like to replace. I can obviously bypass, solder the fuse in-line or use any old holder, but I'd like a "correct" replacement. Does anyone have a source for these? A part number would also help. The other item I have is a DEC Rainbow with a busted power switch. The switch a fairly typical wide rocker style in gray plastic with a 1 and a 0 printed on it. Again, I can replace it but I'd like a "correct" part if anyone has a source, part number or spare. Thanks in advance!

Data I/O 280 -- Promlink 2.7 needed

by r_beaudry＠hotmail.com

Hello all, I have a Data I/O 280 programmer, and I had an old copy of Promlink 2.7 that I used to control it (someone emailed me a copy). I lost the files, and a search of my old email archives came up short. Can anyone .ZIP and email me that specific version? Data I/O no longer supports the 280, and the later versions of Promlink dropped support for the 280.... Thanks! Rich B.

Computer Replica's

by David.Kane＠aph.gov.au

CPUs could have emulated guts, either software or one off hardware designs, with replica enclosures and front panels. That feels like it would result in a reasonable result for the effort required, but mechanical I/O will be the tough bit. I have recently mulled over the idea of constructing a PDP-11/04 replica; I imaged a bent metal case, a replica programmer's front panel, and an internal PC mother board running SIMH would be feasible, but I have shuddered at the thought of trying to interface it to 8" floppy drives (if I could find any), or building a card reader and line printer. BTW: What is the origin of this message? I cannot find it in my mail archive.

by aek＠spies.com

So lets have your vote for what replica's of old computers that need to reconstructed at a functional level -- blinking lights, mechanical I/O but it need not be the same hardware level. -- I'm biased towards machines that no longer exist, but have surviving software: SDS 940 BCC 500 A Xerox Alto using modern components would be interesting as well. It would easily fit into a medium sized FPGA now.

Electronic components sources

by melamy＠earthlink.net

actually, the usual switches these days on PC computers are only logic switches back to the power supply. The power supply does "tap into" the ac line to get a little power it needs. My P4 that I built last year uses an ANTEC case and there is no AC going out to a front panel switch - it is only a push button. A good rule of thumb is that if a switch clicks then it probably has AC on it. If it doesn't then it MIGHT be only low voltage. As an electrical engineer, I would not take the chance and assume it is low voltage without checking. Any computer that is pre-ATX will have AC voltage on the power switch. Some early ATX and maybe even now (I don't know for sure) may still have a real switch out front. The older mini-tower systems that have a power switch out front usually had a AC connector on the back of the power supply and a four conductor cable that ran out to the power switch. The power could tap into the AC line without affecting the switch out front. The older NEC, etc systems sometimes had a seperate power suply with an AC connector and cables, etc that were not integrated into the power supply like the PC, AT, ATX supplies that came along. best regards, Steve Thatcher >--- Original Message --- >From: meltie <lists(a)microvax.org> >To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> >Date: 3/24/04 7:23:31 PM > On Wednesday 24 March 2004 23:45, William Donzelli wrote: >> > Assuming the switch functions correctly (and is wired correctly), >> > the behaviour of a device with such a switch in the off position >> > is pretty certain: it's identical to a device that has the >> > mains lead pulled out. >> >> Not completely.

IBM PC/XT Clone and 1.44MB FDD

by hassan＠SyberDesk.com

Hi, I've got a generic PC/XT 8088 clone (contains NEC processor) with no HDD and two 5.25" FDD. Needless to say that the media as well as the O/S (M$ DOS) is not available in my local market. I was wondering if it's possible to: (1) Install a 3.5" 1.44MB FDD in it. (2) Acquire FREEDOS and boot the machine (3) Use some sort of DOS terminal program to connect to a Linux machine Appreciate any help and guidance. Thanks. Hassan
