Hi everybody, I may have a line on a couple of (probably not yet on topic) coke machine sized AS/400s in the Champaign area. I don't think I have space for them, but I'd like not to see them get ruined. Please let me know if anyone would be interested in these things. I'd like to have some people I could point them to who'd be willing to take these either for some cost or not (depends on the guy who's got the systems...), and save them from being shredded. :) Don't know anything else at this point.

They both use 6502's. That is about where the similarities end. The KIM was a hex readout. The AIM is an alpha/numb readout. The AIM runs a printer in parallel with the display. The KIM has a small key pad, the AIM had a full keyboard. I could pull my chip and disassemble it but someone else could deal with putting comments on the code. I'll look at my AIM stuff tonight and see if they had any listing for the monitor. It seems like they only had entry points but that would be helpful in figuring it out. Dwight

20mA serial cable connector

by uban＠ubanproductions.com

I'm looking for a supply of the uncommon DEC 20mA current loop male connector shells used to plug into DEC VT100s, Wyse 85s, and the like. It is also used to plug into the H744 (and other) power supplies. The DEC part number is 12-09340-00 which might also be a Mate-N-Lock 1-480460-0 I would like to find 12-24 of them. I am assuming that if I can find the shells, I can find a pin from either AMP or Molex which will work. --tom

Office Max events

by Mzthompson＠aol.com

Event #1 I went to OM earlier today to take pick up a UPS that was on sale. Their ad from last Sunday's paper lists a unit at $20 off (and no friggin' rebates to mess with). The ad listed the unit as 500VA. When I get to the store, the clerk points it out to me and the unit is 350VA. I say whoa, it is listed in the ad as 500VA. Turns out they list the model number for a 350VA unit and spec it at 500VA. I asked to see the manager, who already knows me (more on that later). This time I got stuck with the assistant manager. She states that it must be a misprint and she can't be held responsible for printing errors. I don't mind saying that I am getting tired of employees who will not take responsibilty. So I read her my riot act mentioning that she is standing here as a representive of OM and in my eyes is responsible. I also point to Staples (across the street) and mention the fact that a young man over there was also not responsible and after my complaint to Staples on their web sight, he got lectures from the higher ups, not to mention the phone calls that I got from district and regional managers seeking to make sure I became a satisfied customer. Anyway, back to this gal at OM. I mentioned to her that listing the model number of the 350VA unit and the spec of the 500VA unit might be construed as "bait & switch". With that she looked up the price of the 500VA unit and said she would sell it to me for 40 bucks off. Event #2 A few weeks ago I want to OM to buy another sale item. They had a CD-R 100 pack listed for $40 with a $30 rebate. What caught my eye was that they were 650 mb. My CD Burner drive is an earlier model, and does not like these new-fangled 700 mb thingies. So I go into OM and can't find them. A clerk comes along and I show him the ad and tell him that is what I want. He leads me to the big display of 700 mb. I point to the ad and tell him I want what is advertised, not these. You ever noticed how these clerks become dumbfounded and clam up at this point. He suggests I talk to the manager. I did and here again I mention that trying to substitute 750 mb for the advertised 650 mb might be construed as "bait & switch". With that she took my name and phone number and said she would get back to me. She did, she called two days later and said she had 2 100 packs for me. I indicated I only want the one because of the rebate limit. She then explained that the 2nd one was complimentary for my trouble. Now if I just get the rebate, that's 200 CD-R blanks for $10. Event #3 Speaking of rebates. I bought some memory at OM and sent in the rebate. Three months later I had not received the money. So I took all the paperwork into the store. Lo and behold, they have a form for just that. I filled it out and they gave me the $50 rebate right there. Why don't they just do that in the first place? Why you ask am I still going into OM? In this town there just isn't much else and they seem to have better sales. I share all of this because you need to watch out if you are dealing with OM. If they try to pull a fast one, namely "bait & switch", then call them on it. Maybe they will learn to get their ads right, or at least you may get a deal. Mike

I forget which was which but I think it was that the 160x were syncronous bus and the 1x01's were open collector as compared to 1x02's that were 3state. If anyone cares, I can look it up in my doc's to get it right. By the time the 1702A's came out, I don't think anyone saw the others. Dwight

Ms Hughes was referring to the housings of course; the pins that fit the housings are still a current standard product. AMP changed some of the part numbers some time ago, but they are still the same pins that fit the rest of the Commercial Mate-N-Lok range, which includes the ones used for drive power (not the little ones for 3.5" floppies, though -- those are 2.5mm AMP Economy Interconnect). The point being that if you can find some old connectors, you can replace the pins. The part numbers for the crimp contacts are: socket connector, 18-20AWG 163304-2 socket connector, 14-18AWG 163306-2 pin connector, 18-20AWG 163305-2 pin connector, 14-18AWG 163305-2 and you should be able to find them in the AMP catalogue or any of several dealer/distributor catalogues. -- Pete Peter Turnbull Network Manager University of York

Besides my wife wouldn't like me hiding out up there, she doesn't mind when I hid out in the computer room at home. Oh, and then there is the fact that if I'm going to be writing something in BASIC, it's going to be on a PDP-10, PDP-11 or a VMS box. Which brings up the question of how do you clear the screen on a VT100 using BASIC-PLUS-2? The following works on my Alpha using DEC BASIC, and looks like it should work using BASIC-PLUS-2. 1 declare string constant CLS = ESC + "[H" + ESC + "[J" 110 print CLS Zane

Specifications Sought for 7-Track Tape Heads

Quebbeman wrote: > The end-result of this project will probably involve > reading 7-track tapes in analog mode and digitizing > the analog data stream in order to use modern computing > power to reconstruct the data. Well, if you're going to go into digital signal processing, why not just use a 9-track head, and analyse the data from adjacent tracks to recombine into 7 tracks? ;-) I'll bet it's doable. My second-year second-term (10 weeks) assigned project was to build a barcode reader, using a common slotted optosensor with an active area whose diameter was about twice the width of the bars, and a Z80 with 2K EPROM and 8K RAM. It's amazing what you can do with a little circuitry and a little calculation. 9 tracks to 7 should be easier, since I expect the top, bottom, and middle tracks will line up nicely. The second track from the 9-track head would have a mixture of (mostly) 1st and (a little) 2nd tracks of the 7-track signal; the next channel would have a roughly equal mixture of data from tracks 2 and 3; the next channel would be almost all 3; and so on. -- Pete Peter Turnbull Network Manager University of York

A jumper on the > board that allows settings between 2k and 4k is set to 4k > (1702s vs 1701s?) In the absence of documentation, one trick is to examine memory looking for plausible code for your processor. So you learn how to use the front panel to examine memory (and maybe how to deposit too, as that's one way to tell whether the address you're looking at might be read-only) and maybe learn something about the processor's instruction set too. A12 to A15 likely set the board's base memory address at a 4KB boundary with A15 being the most significant bit (and A14, A13, A12 being the next three bits down). A switch set to "on" or "closed" might be 0 or 1, so pick one and write the bits out in A15 through A12 order. Then invert it (1 becomes 0, 0 becomes 1) and write that group of bits out. Now you have two ways to set the high four address switches on the front panel, which cuts the amount of address space you have to explore by 1/8. A 1702 is, what, a 1Kbit device? That's 128 bytes. So start with the low seven address switches set to 0. You can probably assume that the ROMs are each based at a 128-byte boundary. This leaves you five switches in the middle, so 32 steps for each of the ways you can set the high four bits. -Frank McConnell

Both the connectors used for DEC PSUs and 20mA loop, and the connectors used for disk drive power, are (or "were" in the case of the wide flat ones :-)) are from the AMP Commercial Mate-N-Lok series. So are the 3-pin DEC power bus cables. -- Pete Peter Turnbull Network Manager University of York

Solid State Music MB-3 EPROM card question

by classiccmp＠mail.vintage-computer.com

I recently received an Altair 8800 with an Altair disk drive (Pertec FD514 innards). In said machine is a Solid State Music 2/4k EPROM board with 2 proms: DBL and MBL. My understanding is that the DBL prom is the boot loader for paper tape and cassette and the MBL is the boot loader for the disk. Assuming the PROMS (1702s) still hold data, I need to figure out the address of the code. The board has two sets of four dip switches. One is labeled T1 to T4 and the other A12 to A15. A jumper on the board that allows settings between 2k and 4k is set to 4k (1702s vs 1701s?) Does anyone have a manual or a really good memory of how these relate to the address of the on-board PROMS? I?m also interested in finding out how the sockets are addressed. The two proms are in the lower right sockets (the board has 2 rows of 9) and I?d have thought from the markings that the upper left sockets were the first two to be addressed. I?m not yet that familiar with S-100/Altair type systems, but I assume if I know this address I can execute the code to boot the machine (assuming the drive still works and the disks aren?t bad. . . ) Thanks in advance for any help you can provide.

OT: boatanchor mailing lists and resources?

by tothwolf＠concentric.net

I know there are a few boatanchor fans here on the list, so I figured I'd check here before spending yet another hour arguing with Google... Basically, where are the good boatanchor related mailing lists and resources at? I'm looking for resources on restoration and building home brew tube based gear. I have a National NC-2-40-CS receiver that I was given back around 1995 or so, which needs its power transformer rebuilt/replaced, in addition to lots of other minor repairs. Unfortunately, the former/original owner of that receiver passed away before he could find the manuals for it that he had filed away. A couple of weeks ago, I was given an unfinished home brew 2 Meter Receiver that is about 50-60% assembled. It was built by a friend of mine who passed away about 2 years ago. Today, while cleaning out more old parts and gear from his former shop, I found the faded plans for it and a matching transmitter. Both appear to have been hand copied from the October 1957 issue of QST. I don't currently know when I'll have time to work on these projects, but I'd like to have the resources and information I'll need available when I find some free time. -Toth

ASR33 print head

by dwightk.elvey＠amd.com

For those that want on line manuals, check: http://www.pdp8.net/index.shtml Near the end of the page, under other you'll find ASR 33 Teletype. Besides these he has a great site for PDP-8's I was thinking, it might be a good idea to make a mold of the print head I have. One could then make one in the future to replace it. I'm not sure, not having it right here, but I think the head is some kind of metal over plasic. It could be nickel or something that doesn't rust. It could also be low temperature type setters metal of some type.

Another >place dumps box loads of them into an industrial chipping machine. I can >verify these...I've seen it, and it isn't a pretty sight :/ The thing I and the guy who told me about it were laughing at is how useless their "destruction" methods really were. They are using an off the shelf secure delete program (Norton?) and then opening the top of the HD and hitting it with a mallet to damage the platters. So what does this mean... well, I am sure one of those data recovery companies could still extract the info from the drive if someone was willing to pay the fee (which I would assume a rival company that really wanted the info, and was willing to bribe the trash hauler would be able to afford). The computers are (were? they may be done now) under guard and only accessable after the hauler has collected the contents of the dumpster and driven off property... I do know this first hand... I tried to make a midnight run to collect some of the PC remains since it was supposed to ONLY be the mobo and HD being trashed, that leaves lots of good parts for the picking... but I was stopped at the manned gate, where I could see the dumpster and a poor guard sitting by it reading a book... in the cold of winter... so he wasn't there for kicks... and no, the guard at the gate wouldn't look the other way for $100 which was all I could afford to offer (didn't try the garbage truck driver... too afraid it is a Soprano Special company). -chris <http://www.mythtech.net>

Specifications Sought for 7-Track Tape Heads

by dquebbeman＠acm.org

The subject says the first part... I'm seeking a source for the specifications for 7-track tape heads. I'm thinking what I really need is just the mechanical/ physical specifications... that leads me to the second part.. Has anyone here have any experience with disassembling a tape head and re-assembling it? I have in mind delaminating a 9-track head stack and rebuilding it as a 7-track. I can already see that a microscope with a precision mechanical stage will be a must-have for this work. The end-result of this project will probably involve reading 7-track tapes in analog mode and digitizing the analog data stream in order to use modern computing power to reconstruct the data. Yes, this is bascially what Tim Shoppa does now, but I'm not going into business, this would be a labor of love and once operational, would be used only to assist other hobbyists/preservationists in their conservation efforts. And of course, this is the last-ditch effort, as I continue to scan my purview for a working head or a working 7-track drive. Comments appreciated too, but especially pointers to the requested info if online, and maybe an offer of photocopies of not... Tia, -dq

AS/400s in the Champaign area

by csmith＠amdocs.com

> -----Original Message----- > From: Gene Buckle [mailto:geneb@deltasoft.com] > Chris, if you get the chance can you find out if they're CISC or RISC > machines? Sure -- here's what I know about them (it? We'll get to that) so far... The first cabinet is marked "Application Server/400 9406" If I'm not mistaken, that makes it a RISC model. It contains two EMC SCSI arrays, a tape library of some sort, made by Phillips, a <whatever that box with the power switch on it is...>, a QIC-1000, or similar tape drive, and at least one card cage which is mostly full. There is a second rack, but I'm not convinced that it's a separate system. It only says "Application Server 400" on the tag -- no model number, no "system cabinet" label in the back like the other one has. This second rack has (I think) some cards in the cage, and the unit in the middle of the rack with the power switch on it, but nothing else. There are a few other things floating around with these. Twinax cable, power cords, an (I wrote IBM 7206-002, but I can't find that model, and I see that 7206 is a 4mm drive, which this is not... so I think...) 7208-002 external tape drive. So does anyone know how to tell whether these are one system or two? They're actually a bit smaller than I had been told. Each rack is about the size of a relatively small refrigerator. I'm right around 6' tall, and these are shorter than I am. On another note, my fiancee has expressed some interest in it. I'll try to find out over the weekend whether she wants it or not. Personally I don't like AS/400s enough to have one this large ;) The last thing is that the guy who has it will probably want some money for it. As of now, I have no idea how much, nor does he, AFAIK. Anyway, John, if you're still interested, let me know, and I'll see about putting you in touch with the current owner -- assuming that the fiancee doesn't decide she really needs a very large AS/400.

See following. - don The e-mail based PDF accessibility tools have been updated. You can now submit multiple URLs in a single e-mail message as well as submit PDF files to Adobe as MIME attachments. See below for more details. There are three e-mail options you can use to convert Adobe PDF documents to a format that is more accessible to screen reading software. The e-mail address you use depends on the conversion format you want, plain (ASCII) text or HTML, and whether the PDF is on the Internet or local media. Option 1 If the Adobe? PDF is on the Internet, you can mail the URL (Web address) of the PDF in the body of an e-mail message to pdf2txt(a)adobe.com (for plain text) or to pdf2html(a)adobe.com (for HTML). The convertor will mail back the translation of the PDF file. You can submit multiple URLs in a single e-mail.Tip: Some URLs are very long and cumbersome to type. Cutting and pasting the URL into the mail message will save you some keystrokes. Option 2 If the Adobe PDF is on local media, such as a hard drive, CD-ROM, or internal server, it can be submitted as a MIME attachment to an e-mail message. All converted Adobe PDF documents will be sent back to the sender as MIME attachments. For plain text, mail the attached PDF to pdf2txt(a)adobe.com. For HTML, mail the attached PDF to pdf2html(a)adobe.com. Option 3 A service hosted by Trace Research Center also allows you to convert Adobe PDF documents. You can either mail the URL of the Adobe PDF or attach the Adobe PDF document itself to your e-mail message and send it to pdf2txt(a)sun.trace.wisc.edu (for plain text) or to pdf2html(a)sun.trace.wisc.edu (for HTML). The convertor will mail back the translation of the PDF file.
