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

There were originally 4 parts; 1601, 1602, 1701 and 1702. 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.

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.

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

They're not Molex, they're AMP, and since they're the pins for that series of connector they'll work fine.
