FS: Russian Computers

by adavie＠mad.scientist.com

Hi everyone As some on the list may know, I'm mad-keen on Russian calculating devices. I've pretty much concentrated on calculators (please see my award-winning site listed in my .sig), but my many agents occasionally offer computers, too. Typically I don't buy (computers are not my main line of interest) - but in this case I'm scouting around for a buyer. The reason: read on. One of the rarest Russian calculators is the MK-47. It's a magnetic card reading machine - so the rumour goes. None have been seen in captivity. Some 6 months back, one of my agents (from whom I've previously purchased several rare machines) told me that he had an MK-47 for me. I was quite excited. More correctly, his grandmother had found one, and she was to bring it to him the next day. So, I waited for news. And waited. And waited. About a month later, a short email from my agent (Alex) tells me that he has been in hospital, and will be there for the next few weeks. And furthermore, he hasn't seen the calculator yet because his grandmother is ill and in (another) hospital, too. Of course I told him to forget about the machine for now, and get well ASAP. Around this time my personal life was thrown into turmoil when my (5yo) daughter became gravely ill and spent several days in hospital (complications of chicken pox, and drinking skin lotion, for the curious). So, I wasn't particularly thinking about calculators, either. Anyway, a few weeks pass, and I get news from Alex's father (Alex is still in hospital) that Alex's grandmother's house has burned to the ground. You can guess where the calculator was. Still, this is about a house, and that's tragic. A calculator is just an old machine. At this stage, I was beginning to think the machine was jinxed anyway. Alex contacted me later (through his father) to tell me that the fire which burned down his grandmoter's house STARTED in the house of the man who gave her the MK-47 calculator in the first place. Spooky. A few days later, Alex's MOTHER contacted me with the sad news that Alex's grandmother had died, and that Alex's father had had a heart attack when he found out. So, Alex is in hospital, Alex's father is in hospital, and Alex's grandmother has died. Here we are, a few weeks after that. Today Alex told me he is out of hospital. His father is still in hospital, but in less-serious condition. And Alex is on the prowl again (for calculators and computers). As you might understand (if you've stuck with me so far), things have been incredibly stressful for his family - and more to the point - incredibly expensive. Alex needs some extra funds to pay for the medical costs, and here's where I come in. As I said, I've done trades with Alex before, and found him not only reliable, friendly and honest - but incredibly good at finding rare and unusual things. Right now, however, Alex has a few vintage soviet home computers for sale. I've told him about you guys [collectors], and he's asked me to contact you on his behalf. Could anybody interested in exploring the purchase of soviet computers from Alex please contact me by direct email (adavie(a)mad.scientist.com). I have some pictures and details of machines that he has - and will be happy to act as an intermediary - or put you directly in contact with Alex. I have done many, many transactions to Russia, so can offer advice and suggestions regarding transfer of money and computers. OK, that's about all I have to write. This is probably the best opportunity many on the list will get to obtain some interesting machines. And remember, Alex is a champion at finding unusual/rare stuff.

Everyone here should read this.. I thought I'd seen everything.

by mrdos＠swbell.net

I actually thought of that once, but thought I was about the only one who would take it seriously. It's really not a bad idea, and I'm sure our fellow collectors would go for it. We really need an organization to preserve old computers. I go to scrap yards and see classic machines ripped apart all the time. Computers are a big part of everyone's lives now, and just like anything else that changes our society that much, (the printing press, for example) they need to protected. I hoped someone else would have the same idea I did. I really think it is a great idea, worth considering, at the least. >Well, maybe we should start a National Computer Preservation Historical >Society, and then once we have a couple hundred members (should take all >of 1 hour...) then we start sending letters to our representatives asking >them to write a bill similar to whatever empowers the people that preserve >historical buildings and landmarks. > >Of course, real influence comes with a historical society that has been in >existance for many years, but of course you have to start sometime ;) > >-Lawrence LeMay

Sol 20, Morrow Micro Decision Quantum 2080 & more

by Innfogra＠aol.com

Dear list members: I know you are going to hate me for this but circumstances force me to maximize my income. I have listed my last Processor Technologies Saul 20 on ebay. I know many of you were interested. I have also listed a Morrow Micro Decision and a Quantum 2080 8 inch MFM hard drive that can be used with many older systems. My last Quantum sold for $20. Not everything goes for big bucks. My ebay name is innfosale. Please note the two Ns in the name. This URL should bring up my list: http://cgi3.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewListedItems&u… id=innfosale&include=0&since=-1&sort=2&rows=25 For those that are interested, you might bookmark the list. I will be selling more classic computers, S100 and DEC cards, drives, HP, in the future. If you notice I rarely use reserve bids, preferring to let the market set the price. I am good at finding equipment. Many thanks to all for the stories and help on the list. I love reading it even when I've been gone two weeks and come back to 1000 messages. Paxton

Tube experts! - I need your assistance.

by dylanb＠sympatico.ca

I don't like tubes. My experience with tubes is *very limited*. I have had a few crash courses over the past few years...... Okay, I bought the Tek RM503 for my PDP-8/S. When I turned it on I heard some terrible noises and found the power supply voltages were all over the place (way off , like 10V was 500 etc..). This scope uses a primary transformer to supply the 6.3V to most of the tubes and has a separate winding for 6.3V for the CRT heater. Off this transformer another winding fed to a voltage doubler and then to an oscillator with another transformer to create a wide range of voltages. (12V to -3000). Picture this... the -3000 volts is fed right into the CRT heater (which happens to be directly coupled with the primary transformer). I have been able to locate the problem somewhat. If I remove the -3000 volt line between the HV rectifier tube and the CRT itself then the scope works fine! All waveforms are proper and the power supply works great (no picture of course). It can be a few things... I am hoping someone here who use to work on tube units might be able to tell me which problem below it most likely is: #1) A bad HV rectifier tube causing the HV to come back to the second transformer which would put a few thousand volts back into the secondary winding taps causing high voltage everywhere. #2) Bad insulation on the primary transformer secondary "crt heater" winding which jumps over to the other winding that happens to be the main powersupply winding (125V X 2) #3) The -3000 volt wire is closely tied to the other low voltage wires. Is insulation breakdown possible due to a crack? My next step will be to take a reading on the primary transformer (first transformer, secondary winding [doubled winding]) and see if thousands of volts are there... That might help determine if there is an insulation breakdown but from what I can tell when the -3000V is hooked up every voltage goes crazy. I am going to bed.. Hopefully I wake up to a great answer ;-) john PDP-8 and other rare mini computers http://www.pdp8.com

uVaxen & Fixing Basic Proggies

Well, to respond to a few of those VAX-related questions as best I can... :) 1) There are lots of resources out there featuring VAX information; you might want to look at the NetBSD/vax port website (http://www.netbsd.org/Ports), the VAXarchive (http://vaxarchive.org), and Hamster's Digital Resources site, which can be found at http://www.telnet.hu/hamster/dr. 2) I don't believe there is any sort of hobbyist distribution of Ultrix, however you can run the hobbyist distribution of OpenVMS (http://www.montagar.com/hobbyist), or if you're interested in a UNIX, NetBSD is available for a number of VAXen. 3) All microVAX systems use some variety of serial terminal for a system console (although I believe it has to be VT100 compatible, so I'm not sure how useful that ADM terminal will be). VAXstation systems are the ones that use monitors as consoles, however it is possible to get them to run over a serial console as well using a few different methods depending on which model you have. Hope this is helpful :) -Sean Caron (root(a)diablonet.net)

new additions + serendipity

by SUPRDAVE＠aol.com

Decided to make a thrift run today and in addition to getting an IBM L40SX last week, got this stuff today: complete amstrad pc6400hd even got the owners manual. good shape too C128 in box plus 1024 monitor and the 1530 tape unit in box as well as a 1571 drive in box and about 400 disks of software as well as all cables. an atari 400 box filled with about 350 never used 5.25 floppies. total price not including the L40 was $7. whilst rooting around in the junk for sale, i met a guy who was a (presumably) IBM CE back in the old days and spoke of servicing plugboards and paper tape and such. he also worked on IBM selectrics. from what he was saying, he has some old Freiden calculators or some sort. he didnt know much of current pc stuff, but told some fascinating stories of the old technology in the short time we spoke.

Processor Technology S100 memory boards

by edick＠idcomm.com

SRAM boards (that is what these are, isn't it?) are usually simple enough to troubleshoot that you can get by with just a 'scope and an hour or so of time, depending on how inclined you are to work on the hardware. Each RAM device will have a write strobe, a select strobe, (maybe a separate enable as well) and some data inputs and outputs. Because it's a 16K board, I assume you have 4kx1 or 1kx4 SRAMs. (similar to 2147 or 2148 types, respectively) The 1Kx4 parts have common I/O, and both types are 18-pin DIPs. These 16K boards use 2147's don't they? Does your diagnostic (whatever it is) tell you which bit is failing? If it can't read the bits, perhaps it's a (1) a failed decoder or (2) it's a failed data bus buffer, or (3) it's a roached address buffer. The only apparent alternative would be a failed RAM. It does smack of a failed on-board decoder, however, since only the one 4K block is failing. If you can't read/write even a single bit in that 4K block of RAM, it's undoubedly a buffer or a decoder. If only one bit fails, it's probably not a decoder, but then the RAM itself is suspect. Since the failure is in the "middle" of your board, it's probably not difficult to compose a loop which cycles through the ram board in 1K blocks, doing a write to one location in each 1K block, first the lsb, then left-shift and do it again, etc. This enables you to trace the device select, and write strobes through the circuit. A 16K board in a 64K memory map ought to be pretty simple to decode. There should be jumpers/switches to select which 16K block in the memory map the board occupies, and there should be a 2-line to 4-line decoder to select the individual bytes of memory. If the organization is as 16 pairs of the 2148-types, then there's probably either a 4 line-16 line decoder (e.g. 74154) or a pair of 2-to-8 types (e.g. 74138) to select a byte of RAM for each memory cycle. Assuming you have the equipment at your disposal, you can determine whether each RAM device is receiving the write and select strobes at the correct times, and likewise, whether they get their enable and select when being read. IF those are both correct, you then write a loop which writes all zeroes to the rams and then having finished writing the zeroes, cycles infinitely on reading them back. You then look to see where the zeroes no longera appear as zeroes, bit by bit, until you have it narrowed down to one data bit and replace the device which isn't transmitting the zero. If they all transmit zeroes OK, then you write all ones out to the ram board and then look for where the zeroes coming from the ram are no longer zeroes. It's not a bad idea to monitor the write operation as well to see that the data makes it TO the RAM in the correct sense, inasmuch as the S-100 has separate in and out busses. This whole process, aside from the associated repair shouldn't take too long and will fix the problem once you isolate and replace the failing component. If, however, you're determined simply to move the failing block of memory to the top where it's easy to ingore, you can switch decoder outputs by tracing back from the failing block of RAM to the decoder and then cutting the traces and soldering on the jumpers which will accomplish what you want.

pdp-11/60 Semi-Rescue

by mcquiggi＠sfu.ca

Hi Gang: Well an 11/60 is going to the scrappers on Monday here in Vancouver. It's at an acquaintance's house, he got it and never got around to getting it set up in his basement. I can't take it due to lack of storage space. Too bad, it's complete, although it's been stored in a garage and not powered up for about 10 years. I am, however, going to save the CPU cards, any other cards, and the backplanes. I will also try to save anything else that can be readily removed from the machine. I did try to find a taker for this beast, as you'll recall from the lists, but unfortunately it's been almost a year and the potential takers have not been able to get around to picking it up. He cannot wait anymore and has arranged for a scrap metal dealer to pick it up this Monday. This is a sad situation, but at least I'll be able to save some of the machine. I'll post to the lists with my results. Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

List spammers located, LARTs launched

by kyrrin＠bluefeathertech.com

Ok... I don't know about the rest of you, but I've about had it up to my eyeballs with the soulless morons who keep spamming CLASSICCMP. I just sent off an E-mail to Derek Peschel asking... 1). That the list be configured to accept DIRECT (unscreened) postings ONLY from subscribers. 2). That I be permitted to volunteer to screen all non-subscriber postings before either (a), passing them on (and if they have even the slightest connection to subjects on CLASSICCMP, be assured that they would get passed on promptly), or (b), tossing them in the bit bucket. Since I seem to be the most experienced spam-fighter in the group (and I'm open for challenge on that), #2 made sense. It would allow me to trace back and LART spammers without their crap ever being seen by the list members. If you have any thoughts on this one way or another, please address them to Derek (dpeschel(a)u.washington.edu) with a CC to me.

OK, I confess it's been almost a day since I worked on my PDP-8/m. I discovered that I appear to have, what looks to me at least to be, a very serious problem. I thought that one of the LED's for showing the address was out, been that way for at least a couple days. Then yesterday morning I put it on the table I've been using when I'm working on it, and another LED was out. Another address LED, but the one for the second bit, in other words set it to address 0002 and it looks like you're at 0000, grrrr! So I pulled the front off and discovered that the solder connections have apparently gone bad. I reheated the solder, and added a little. That fixed it for shortly longer than it took to get the front back on. The two LEDs are back out. Even more frustrating, checking out E46 on the G227 with my new TDS-220 Oscilliscope it looks as if everything is just fine. Yet the other day when I checked it with the logic probe it wasn't (still have the same problems with memory though). Probably better explain this, I'm seeing 'pulses' on the outputs that correspond to those on the E39 chip, in other words one chip is doing the xxx0 - xxx3 and the other the xxx4 - xxx7, which I wasn't seeing before. Still I really should recheck the results with both the Logic Probe, AND the Oscilliscope. So, I'm starting to wonder if I don't have some fairly serious problems with the solder joints in this system. What is the best way to check for this, and fix any problems that I find. In any case I obviously need to get a decent soldering iron, the el-cheapo Radio Shack one I've got is as old as some of the parts in the PDP-8! If nothing else I need a decent tip. Zane | Zane H.

super star trek source

by jim＠calico.litterbox.com

Since there was significant interest in these scans (and to avoid hogging our link to the net and incuring the wrath of my spouse) I have uploaded the three pages of Ahl's book containing Super Star Trek to www.litterbox.com/jim Like the page says, they're quite large - around 2 megs each - in the intersts of being OCR-able. (scanned at 300dpi) My page is very vanilla html, so any old browser should work, including lynx. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

Solder actually sticks to a metal surface by forming a very thin layer of an alloy with it. In effect, the solder dissolves the other metal very slightly. That's partly why a copper soldering iron bit gradually wears away even if you keep it well tinned, and partly why thin plain copper cable that has tinned ends is weakest just at the point where the tinning ends (the solder leaches away a tiny amount of copper, leaving the wire slightly thinner just at the junction). -- Pete Peter Turnbull Dept. of Computer Science University of York

"Silver solder" is an extremely vague term, covering everything from special low melting point Indium-Silver alloys to 2% Silver/tin/lead solders to brazing, depending on the context it is used in. The indium-rich solders are *really* neat stuff, if you ever get a chance to work with them.

And many indium > solders will even wet and stick to *glass*. Yes, you just reminded me of a visit years ago to an optical works owned by a friend's father. How do you mount an unfinished non-circular glass lens in a lathe (of sorts) to finish it? Answer: you take some LMP alloy such as you describe, melt it in a short cylindical mould, float the lens on top, let it cool, and mount the cylinder with glass attached in the lathe chuck. To remove the alloy later, place it in a warm water bath. -- Pete Peter Turnbull Dept. of Computer Science University of York

Whats the screwiest thing you collect?

by xds_sigma7＠hotmail.com

Ok, Well I suppose I will add my odd collections to the list: First off, old computers, naturally. I also collect stamps, with a particular emphasis on revenue stamps I collect old documents with revenue stamps on them. This is why I have around 40 or so 1860's mortgages, all of them have revenue stamps on them. Along the same lines, I have an 1885 license to sell manufactured tobacco. I also collect various mediums for recording sound. I have a CD player, cassette deck, several turntables, a Rio, multiple reel to reel tape players (one of which is run by vacuum tubes), and a few 8 track decks. No wax cylinder player yet, unfortunately. I also have, as my secondary refridgerator, a 1952 westinghouse frostfree refridgerator, which still works great. I've started collecting vacuum tubes as well. I also collect classic cars, to which end I have a 1967 Plymouth Barracuda and a 1970 Oldsmobile Cutlass S. I also would like to get a couple of old tractors at some point. I also have a whole bunch of random car parts which don't go to any car I have ever owned (my honeywell lineprinter is sitting on a stack of Corvair rims in my garage). I'm sure I collect other weird stuff, but thats all I can think of currently.. oh wait, coins also.

Silver solder is certainly very nice, flows well, bonds to a lot of metals, etc., but isn't it usually _higher_ melting point? Conventional solder melts at around 450 F, I think.

Not usually; the whole point of most silver solders is that they have a low melting point compared to, say, brazing alloys, and can be used with a butane or propane torch in air. The cadmium-free ones, though, are used because they don't adversely affect other materials (eg titanium) and they have rather higher melting points, similar to brazing alloy or even higher. -- Pete Peter Turnbull Dept. of Computer Science University of York

Oh yes it does :-) "silver-loaded" solder only contains tiny amounts of silver (about 2%) but "silver solder" usually contains more silver than any other constituent. EasyFlo is 60% silver, and most are between 30% and 65% silver. The cadmium-free versions contain more than most: Ag19 is 85% silver, 15% manganese. So the book says, anyway, I've never felt the need to put anything that expensive in a blowtorch flame :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

VMS 4.7 was VAXstation 3100 history (Was ... different)

by truthanl＠oclc.org

Zane, Do you stay with DEC OEM Model NUMBER on replacement? What utilities exist to help identify drives to a MicroVAX? Can I "dummy" some CYL/SPT/Hd count and hand it to the MicroVax and have the OS Come in later and claim its an RD5? something provided the figures match? Like, Whats the difference between a Quantum Q-540 and a DEC RD52? Since Allison Parent mentioned that the RD52 was a Q-540, I have looked it up in "The Hard Disk Technical Guide" by Micro-House. All the details are there. If I were to Find a Micropolis or CDC drive that fit some larger DEC equivalent on CYL/SPT/Heads MFM ST506 RPM etc what would stop me from generating a workable drive profile?

by truthanl＠oclc.org

Thanks for the thread. I have I Plessy 6700 PDP 11/24 work-alike, But its native drive is SCSI. I will Check into alternate controllers / formatters. DEC Model numbering is greek to me Sincerely Larry Truthan Yeah, sure, folks have been doing this for about a decade and a half. See, in particular, ftp://ftp.spc.edu/third-party-disks.txt At a minimum, before getting any further, you're going to need some way to format arbitrary MFM drives to what the DEC controllers will expect for a low-level format, either a VS2000 with its built-in console formatter, or one of the DEC XXDP formatters (ZRQB for the RQDX2, ZRQC for the RQDX3) and a PDP-11 to run them on. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

As an alternative to my previous suggestion, I've seen frequent mention over the past decade or so in the DEC-related newsgroups to a program called "RZSPINUP".
