Romania: complete PDP-11/93 on offer for $

by nigel.d.williams＠gmail.com

As I have a webpage (www.retroComputingTasmania.com<http://www.retrocomputingtasmania.com/>) describing my attempts to resurrect an PDP 11/93 I was contacted by a company from Resita, Romania who have just decommissioned an 11/93 in operation since 1993; it includes 5 DEC VT terminals and a non-functioning line printer. They describe it as a "PDP 11/93 193 QZ-D3, model HB9642- JB" They are inviting offers for this system, in their words "...for a fair price proposal.". Cellphone quality pictures sent to me are linked here: http://imgur.com/Hj6fR http://imgur.com/CJU3q http://imgur.com/docPG For my curiosity can anyone tell me what the cabinet on the right is likely to contain? is it disk expansion? Contact me off-list if you want to see the original emails. Please contact Zoltan Korka (zkorka AtThisDomain resitareductoare.com) www.resitareductoare.com

Free Apple Mac LC, London

by lproven＠gmail.com

Anyone want to give this a home before I recycle it? Original Mac LC - 68020, MacOS 6-7.5. Doesn't boot, but that might be the dead battery. I've checked; all my spares are dead, too. 40MB SCSI hard disk & I suspect 2MB RAM / 256KB VRAM. http://lowendmac.com/lc/macintosh-lc.html I might even deliver if it's inside the greater London area. Ask me nicely! Keyboard & mouse can be supplied with it. You've very welcome to a monitor too, but if you want one of them, you'll have to collect it. -- Liam Proven ?

Origin of the term minicomputer (was Re: PDP-1 as ...

by c.murray.mccullough＠gmail.com

It?s my understanding, and I stand to be corrected, that mini, hyphenated or otherwise, simply meant a small computer system that preceded the microcomputer era. Granted this, the term means different-things-to-different-people, the consensus seems to be that the term mini means smaller than a mainframe and matches comparable words from the 60?s, i.e., mini-skirt, et al. As a(n) historian I treat it as a cultural phenomena rather than just a purely technical or technological definition. Whether purists agree is indeed debatable! Murray--

Mostly OT: Looking for Manual/Schematic for Wavetek 1901C

by derschjo＠mail.msu.edu

Snagged a Wavetek 1901C last week. This is a 12" oscilloscope display (X/Y+intensity input), I was hoping to use it as a point-plotting/vector display for a couple of little computer projects of mine. (Or maybe just hooking an Asteroids board up to it... :). It's in pretty good shape (has more screen burn than I think I've ever seen in a few spots, though.) I fixed a couple of cold solder joints and it's now mostly working, except something appears to be going slightly wrong in the Y deflection or amplification (it's getting clipped/distorted depending on the gain and input intensity). Anyone have a service manual or schematic for this thing or know good sources for such things? Thanks as always... Josh

BOUNTY: HP/UX 11i driver development

by doc＠vaxen.net

This is a bit off topic, I guess, and a repeat, but ClassicCmp is still probably the best place to ask. My company runs a bunch of HP83000 mainframes (F330 models) in product testing. We're tied to Agilent SmarTest v5.x-6.03 running on HP/UX v10.20 for test vectors. SmarTest interfaces with the test frame via an Agilent-branded fiber optic PCI adapter. The card is marked E2777B, p/n A3850-0583. It's a buffered serial adapter on a PCI bridge and that's all we know about it. SmarTest will run on HP/UX 11i, but the interface drivers will not load. We don't have source to the drivers in question, the card itself is, as far as we can discover, entirely undocumented, and neither HP nor Agilent has any interest in maintenance or further development. My company will pay a fair boatload of cash for an 11i-compatible driver. If you're interested and have the background & skills to tackle this, contact me off-list. Doc Shipley

How about Series/1?

by trebor77＠execpc.com

How about Series/1? The Series/1 was the first entry by IBM into the minicomputer market as such. I just happen to have one sitting in my Basement. Brought it home around 1992 but never got it up and running. Should have added a 110 Volt 30 AMP Circuit but didn't. Its a 4952/4953 Half Rack W/a 9Meg HD setup for 110 Volts. Plus I have a external Floppy drive that used to work. I had an IBM Guy convert a 4955 Model E to 110 volt but I also have to original 4952. I plan on firing up the individual components through my Lab-Volt with a variable 120 Volt 3.5 Ampere Output if that will work without blowing something. "Any Thoughts Anyone???" Anyone out there running a tape drive setup that could read 6250 10" reels. I have about a Dozen, mostly backup tapes from the Working system. One is an IBM Diagnostic Tape. Maybe I can get in running. Going out west for a couple of weeks to Pan out some Gold flakes. A couple of Ounces will give me some cash to work with. Been retired since 1996 so Income is sparse.

need 35 P112 preorders

by dgriffi＠cs.csubak.edu

So far I've gotten only four P112 kits preordered. I need at least 35 of them preordered to get the thing rolling. Paypal will only allow me to do refunds and get the fees back within 60 days of a payment. 60 days after the first preorder is October 11. Because of that, I'm moving the preorder cutoff date to October 11. If I can't get enough preorders, all money will be refunded. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

PDP-1 as minicomputer

by thomas.gardner＠sbcglobal.net

The earliest use of the term "minicomputer" is about 1968 (Google news, other sources). FWIW, I also think relatively small physical size was a necessary condition for a computer to be characterized as a minicomputer at least thru the mid 70s. IMHO the IBM 1130 introduced in 1965 is an early if not the first minicomputer. To quote the 1965 IBM announcement: "The desk-sized 1130 is designed for individual use by engineers, scientists and mathematicians. But with its range of peripheral units, the 1130 also will be used in such fields as publishing, construction, finance, manufacturing and distribution."

Many adaptors are available, prices $3 - $70. Driver software appears to be Windows only (9x - XP). The programmer looks like a single free-standing circuit board, ~9 IC's plus a lot of sockets including a DIP ZIF socket. USB power, "DB25" data cable (!). Ah, reading further, there's an AC/DC power adaptor as well, so I guess you don't need a PC with both USB and Serial.

Some DG 1200 progress

by jwest＠classiccmp.org

I found some appropriate C&K switches (7101 and 7205) in a bin at the local surplus electronics scrap place, $1 each - so I have a usable front panel. This is good because I really didn't want to cannibalize another perfectly good front panel. I also got a jarring reminder when installing them that my soldering skills have degraded over time. Thank god for solder-wyck :) I cleaned up the backplane and all edge connectors with progold, tested out the power supplies, and the machine sprang to life. It would appear that all the bulbs except the LSbit in the address row work, which is good as the bulbs seem pretty unobtanium. I'll keep digging to find a source of spares for the 2176D. The bulbs have no markings on them, but they are fed via an 11v supply. It looks like they are tied to ground via a 1K resistor which I'm guessing is a warming circuit. I do find it rather odd that they are soldered in place instead of socketed, and since the bulbs have no metal at all - just two very thin leads coming right out of the glass - they seem pretty fragile. I can deposit and examine correctly to all 4 cpu registers, but memory is a different story. There are a few spots in memory that I tested (at 100o for the one 8K stack and at 20000o for the other 8K stack) where I can deposit and read back as expected. However, there are a fair number of spots where if I deposit a value, the machine goes into run mode when I hit the deposit switch. Doesn't that sound more like a cpu card issue than memory or front panel? Next task is to try and decipher the documentation for the backplane and the J & P connectors, so I can tell from the schematics where things are supposed to be and where they go. The fun begins! Best, J

Dear Marcus, You talk about our product ..thank you ! But it will be better to contact us , and i can explain to you why our products are expensives .. Do you know really the price ? Do you remember also what was the price of the product we are replacing when they had been sold ? As examples :(and i can give to you a lot..) -The RD54 from DEC was a Maxtor XT2190 with DEC format. DEC price list , as formatted unit , was 9200 USD , 20 years ago !!! -The Shugart SA850 , 8 inches floppy drive ,price list through their resellers..2800 USD...30 years ago !! A lot of industries and "others" are still using them for differents reasons and they need to be replace as simple they want without changing any software , nothing !! just to unplug the drive ..and plug emulator , and then start again !!.. We also offer to copy "bit per bit" their data and format , because often they are no more able to do the format.. You can conatct me at glb at datex.fr Best regards. Guy LE BOUGEANT. President.

Defcon 18

by ggs＠shiresoft.com

While not normally of interest, I wanted to let folks know that a friend of mine (and fellow classiccmp'er) was at DefCon again this year. He's been going and taking various classic computers to show off (and get hacked). I received a call from him a week or so before DefCon asking if there was something "interesting" he could take as he didn't want to take the same stuff as last year. I offered up my large PDP-11/40 (3 racks worth...he added a tape drive). It was a hit. He had booted BSD 2.9 and gave out a guest password. He parted with "If you want 'root' you'll have to do that yourself". It was after all a hackers convention. 5 minutes later someone came up with a note with the password on it (they used his ancient Sparc to do a dictionary attack). Pictures of the machines are on Wired site here: http://www.wired.com/threatlevel/2010/08/gallery-defcon-18/13/ DefCon's gallery is here: https://pics.defcon.org//showphoto.php?photo=743&title=retro-computing-1&ca… TTFN - Guy

[gopher] OT: Anyone interested in text editor programming? (fwd)

by spectre＠floodgap.com

I figured some people on this list would want to play with this. >From the gopher-project mailing list. ----- Forwarded message from N. Theodore Matavka ----- From: "N. Theodore Matavka" <... at gmail.com> To: gopher-project at lists.alioth.debian.org Subject: [gopher] OT: Anyone interested in text editor programming? Hello, world! I know this is a Gopher mailing list, but I know that there are some budding developers among you. Recently, I have rescued some software >from the bit bucket, and I am asking, if it is not too much, if there are any among you interested in bringing a great old editor back to the forefront. I am talking about TECO: the famously cryptic Text Editor and Corrector, now made far less cryptic due to the addition of a GUI. If you have ever done any amount of work on HP or DEC minis, you must know what I'm talking about. If not, here's a quick rundown: TECO was the first-ever programmer's editor to be written, in the tradition of vi and emacs. In fact, emacs is a direct descendant of TECO, having originally been called Editor Macros. It is included as system standard on all manner of VAXen and PDP-10s. Its one main drawback was that the buffer of text that was being worked on was not visible except on-demand, and one could completely mangle a document with just a few keystrokes, until someone managed to write a version of TECO that displayed the text buffer all the time. Video TECO is an attempt to re-create this great old editor in a version that any Tom, Dick, or Harry would understand. It was written by Paul Cantrell ten years ago; the files had been lost, until I discovered a snapshot of the source hiding in my e-mail inbox. I've even found a patch to make it run on Linux. So I've re-released it under the Sleepycat Licence, and I am currently enlisting developers to help me add new features and squash bugs. I've got plenty of documentation from DEC and HP as to how to work this editor; I've been using it for quite a while in its old version, and would surely appreciate video TECO. A version of video TECO already exists on VAX, and it is only by luck that I managed to find this version for PC. I have just put the files on SourceForge, and they are available at: https://sourceforge.net/projects/newteco/. Please assist me in this great endeavour. Cordially, Nick Matavka. _______________________________________________ Gopher-Project mailing list Gopher-Project at lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/gopher-project ----- End of forwarded message from N.

The VT420 have both DB25 and MMJ, so I can't see how that could annoy anyone. (As do all DEC terminals from the VT220 onwards.) However, MMJ is actually very nice. Too bad it didn't catch on outside of DEC. But I try to use it for everything I can at home. The power switch I can agree on. I don't fancy that slider. Keyboards... I know people have very different opinions on those, but I think the LK201 and LK402 keyboards are wonderful. I really dislike IBM PC keyboards. Way too long key presses, and to much klickety klack. And all the copies of them are even worse. The VT100 keyboard is not a favorite, though. That one also have too much travel when pressing a key. No, I can't honestly think of a keyboard I like better than the LK201 and LK401. And I really think they layout is way better than what IBM dreamt up. The reliability of the VT420 seems to be pretty decent. I've had many more VT320 fail on me. But we have to remember that we're talking about 20+ year old equipment now...

Logic analyzer pods

I know this may be a long stretch, but one almost never sees logic analyzer pods on ebay, usually someone with the box who is way too proud of it. Here is an auction for some K100D pods, and if you look at the other auctions there are others, I think. Thought I'd pass it along for those interested, since older logic analyzers are pretty useful for the people on the list. 130410451946 They are also "Buy it now" so first come first served if the price isn't too high for you.

IMSAI 8080 power supply ratings...

by derschjo＠mail.msu.edu

Hi all -- So the recent discussion of static RAM and the power consumption thereof has lead me to figure out what the approximate rating for my IMSAI's power supply is, before I inadvertently overload it. I have an IMSAI manual that describes the PS-28U as having a rating of 28A on the 7V supply, and 4.5 on the +/-13.5V supplies. Unfortunately, the PS-28U does not appear to be the supply I have fitted in my IMSAI, based on the component descriptions, schematics, and pictures in the manual. I'm unable to find schematics or a manual for any other IMSAI 8080 power supply other than the PS-28U. I have a picture of my IMSAI's power supply at: http://yahozna.dyndns.org/scratch/imsai/IMG_0244.JPG. It contains a 17,000uF, a 12,000uF, and a 95,000uF capacitor. (And a very large transformer as well.) Any IMSAI experts out there familiar with this particular variant? (And thanks again for all the help with the static RAM. I have been offered some 2147s locally and with those, hopefully I'll be able to get the 32K board running again...) Thanks, Josh

Having recently migrated all the stuff on *.trailing-edge.com to a 2010 era server (as opposed to the 2000 era server it was on - previous to that it had been on an Alpha with VMS, and previous to that it had been on a VAX with VMS) with fresh installs of all the software I was pleasantly surprised with the advances that have been made in apache and mailman configuration over time especially with respect to virtual domains etc. In particular the Ubuntu distribution was very straightforward to deal with... after I had adopted to the more modern configuration techniques. And spamassassin can be better integrated with postfix and mailman than in the past, to the point where the obvious spams never have to make it to a moderator's mailbox or turn up as a bogus request to the admin address. I'm not sure you need to stage through an intermediate platform, BTW. Just bite the bullet and go to the final platform. Unless you really enjoy installing and configuring everything twice. Although I was pleasantly surprised with the new Apache etc. configuration methods I still wouldn't want to do it twice. Tim.

Static RAM chip source (& S-100 related questions...)

by derschjo＠mail.msu.edu

Hi all -- I finally have procured enough hardware to get my IMSAI 8080 running again, albeit in a very barebones state. I currently have only 16K of working (and compatible) memory and am trying to get an additional 32K static RAM board working again (It's an IMS board, see: http://www.s100computers.com/Hardware%20Folder/IMS/32K%20Static%20RAM/32K%2…) Mine is missing a number of memory chips; these are 5257 4Kx1 (I believe >from my research the TMS4044 is equivalent). Can anyone suggest a reputable place to pick up half a dozen or so of these for a reasonable price? There are a few on ebay for $6 each, which seems a little steep (but perhaps my expectations are out of order...) I'm also looking for a manual for a PSS RAM65. I believe this is a 16K DRAM board. It's the only S-100 board in my collection that I haven't managed to find a manual or schematic for... Once I get the memory situation resolved I hope to get a floppy disk system working. I currently have a Tarbell 1011D in unknown condition -- is this a decent card to work with (and can it be made to work with 5.25" drives?), or would I be better off finding something else? Thanks as always, Josh

Interesting! Hmm. Unfortunately I don't have any VT320 around anymore, since all of them have broken down (flybacks mostly). But I've had atleast five of them over time, and all have had removable cords. I wonder if this might be more of a european thing. Since different countries in Europe use different power plugs, it makes sense to have the power cord detachable. There is more or less a standard format plug that goes into any kind of computer equipment, but the wall plug differs between countries. So you usually don't use a fixed power cord, but instead the standard equipment power connector on your equipment, and then ship whatever power cord is used in that country. >> > The VT420 have both DB25 and MMJ, so I can't see how that could annoy >> > anyone.

Well, I have four VT420 at home right now, and they all have both a DB25 and detachable power cord. Since I was feeling creative tonight, I even took pictures of the back side of all terminals I have at home. So here is a link to where you can see the backside of: VT-330, VT-420, VT-510, VT-520 and VT-525. All of them have DB25 and all of them have detachable power cords. http://www.update.uu.se/~bqt/vt (Argh, I just realized I missed the VT-240 I have, but oh well...)

That is totally backwards in more than one way. Yes, MMJ "fixed" one thing. It has nothing to do with ethernet, but all to do with people (and companies) who couldn't figure out how to wire a DB25. Almost all companies got the gender wrong on their equipment. In addition to that, many couldn't figure out what a DTE and DCE was. Now, that is called standard violation. Causing people to have cables they think they can connect, but which don't work. DEC is one of the two companies that did get it right (the other one being HP). To this day, it totally amaze me how so many companies couldn't get this right. And >from that perspective it don't surprise me when people around here don't get it either (there was a long thread not long ago, which I declined to even participate in). RS-232 is so simple that it's hard to get wrong. There is only two things you can mess up with. Connector gender, and DTE vs DCE. How can people find that so difficult??? And if people and companies had actually stayed with the standard, you wouldn't even had been able to mix those to parameters up. A DTE *should* have a *male* DB25. A DCE *should* have a female DB25. A male-male cable should be crossed, a female-female cable should be crossed, a male-female cable should be straight. There is nothing more to it. All terminals and computers are DTEs. Modems are DCEs. But it you absolutely wanted to, feel free to wire a modem up as a DTE. It will work just fine, just as long as you fit the right DB25 to it, and wire it up accordingly. But no. Companies just loved putting female DB25 on their terminals, and wire them up as DTEs. Or put male DB25 on their computers, and wire them up as DCEs. *Idiots* That is called violating the standards. And to make matters ridiculously worse, we have IBM. Who simply put just raped the RS-232 standard by using a DE9, moving one or two pins in a totally non-logical way, changing the gender, *and* sortof wiring it as a DCE. They should be taken out to the back and shot. IBM have caused more damage to the computer world than all other companies put together. Here is a simple tip for the next time you wire a RS-232 up. Measure pin 2 and 3 on the equipment. One should at around -12V, while the other is around 0. Do this on both sides. Then wire the -12V from one side to the 0V on the other for both 2 and 3. And run pin 7 straight through. And that's it. You now have a correct RS-232 cable, albeit just the data leads. You can wire the rest up if it amuse you. The most important ones are DCD, DTR, DSR, RTS, CTS. For a DTE-DTE, you should wire CTS to RTS and DCD+DSR to DTR. Very simple. And if I remember right, we're talking about pines 4,5,6,8 and 20. But I'd usually check the RS-232 DB25 connector layout before I try to wire a full cable up. Most of the time I'm happy with just 2,3 and 7 anyway, since I don't do hardware flow control (another RS-232 standards violation, by the way, and which DEC did not do). But having the DSR signal is useful to detect if someone gets disconnected. What DEC did with MMJ was in no way violating any standard. Noone in his right mind would think that an MMJ was an RS-232. So what standard did they violate (if I may ask?). Hmm, I seem to remember that the signalling in the MMJ is even called DEC-423, but I might be remembering wrong. It is pretty much compatible with RS-423 anyway (might be equivalent), and you can usually get away with connecting that directly with RS-232, but they are not really the same thing. (Hmm, looking at RS-423, it would appear that DEC-423 is a superset, since DEC-423 don't actually use a common ground for everything, but use one ground for all transmitted signals, and one ground for all received signals). So, the signalling in the MMJ connector is only claimed to be communicating using DEC-423. How would that violate any standard? If DEC had said that it was an RS-232 port, then they would have violated the RS-232 standard. (I guess I'm confused at your definition of violating a standard.) What MMJ solved was that they removed the gender issues, and they simplified the DTE/DCE issues. Your cable is either straight or crossed (either flat or turned 180? looking from one end to the other). They also simplified the assembly of the cables compared to RS-232. The fact that MMJ Ethernet vs. RS-232 on a RJ45? Give me a break. None of that even existed when the MMJ came about. And the idea of putting RS-252 on an RJ45 is something I'd call violating a standard, if anything. But it comes with the one-connector-for-everything that some people are so fond of. So you also have telephony on RJ45, to make life really interesting... And all running through one patch panel. >> > The reliability of the VT420 seems to be pretty decent.

You're right. For some reason I was thinking that the VT220 also had MMJ, but it didn't. That only came with the VT320... But I can't see the relevance of MMJ vs. RJ45 either, for various reasons mentioned above.

transistor replacements

I'm playing around with an old gizmo that calls for mps-u05 and mps-u55 transistors. They're obsolete, but easy enough to find on Ebay. I would rather use something more modern, particularly because these are in a power supply. Can someone suggest substitutes in a TO-220 case?

cctech Digest, Vol 84, Issue 16

by jonas＠otter.se

Use alkaline or silver oxide. Any small error in exposure caused by the difference in voltage is compensated for by the exposure latitude of the film. I had my OM-1 modified with the Schottky diode setup, works perfectly. I believe it would probably work just as well without the diode. And as far as the diode goes, I have heard one person claim that it is entirely pointless because the voltage drop over the diode varies so much with the ambient temperature that the compensating effect is essentially nullified. Don't waste your money on any fancy adapters, or expensive zinc-air batteries either. Alkalines work perfectly well enough. /Jonas On 8/13/2010, somebody and Tony Duell wrote: >> battery: that's a problem with my Minolta SRT series SLRs, where the > >I think that's unlikey.

Pronouncing acronyms (was Re: DEC acronyms)

by jonas＠otter.se

Sorry about being so unclear, I thought you might be a member of the group in question. Actually, it is quite the opposite, he keeps saying that you shouldn't take a lens apart without having sophisticated equipment to collimate the lens when putting it together again, as well as considerable experience using the equipment, unless you want to have a clean but expensive paperweight. He thinks that if you just put it back together again the optical performance will be terrible. I wouldn't know, I haven't tried. I'm not sure I believe that companies like Minolta who made thousands of lenses wouldn't have worked out a way to make the optical elements self-aligning or something. It sounds like a lot of expense for a manufacturing process for consumer items. Anyway he claims to have years of experience designing stuff for spy satellites or something, however that might relate to commercial camera manufacturing. /Jonas On 8/13/2010, ard at p850ug1.demon.co.uk (Tony Duell) wrote: > >Well, if he's suggesting spaying soemthing into the lens (yes, I have >seen that suggested!), I certainly disapprove.

part # is CDINT339 it allows you to plug in a SCSI device, and use your (parallel port) printer at the same time. Are drivers required? I remember Mike Brutman had one or something similar. He used it to drive a zip drive on a Peanut IIRC. Can anyone inform? Thank you kindly. The possibilities this item opens up are truly infinite. I can barely contain myself.

CAMAC Crate Available Cheltenham UK

by fryers＠gmail.com

G'Day, I have accumulated a CAMAC crate that, despite my best intentions, I am never going to use. I have a whole load of cards for it. If anyone is interested I'll produce a list of cards. The crate and cards have spent some time at CERN and looking at the stickers on it, at other laboratories around the UK. As usual, I am happy to deliver in the UK if it is not too far from where I may be passing - which can be a lot of the UK. Otherwise it is collect from Cheltenham. I may consider posting if anyone is serious enough - weighs well in excess of 20kg, and quite possibly 30+kg. Thanks.

SUN Equipment Available in Cheltenham UK

by fryers＠gmail.com

G'Day, I am in the process of cleaning out my collection of systems pending a move to Australia. I have the following SUN systems I would like to pass onto collectors: SUN E450 (unsure if it has memory, no disks, I was given a SCSI controller for it but I think the controller is HVD). SUN SPARCstation 2. It has memory (I forget what amount). 2 x 200MB Disks, NVRAM hack with external battery. SUN 411 disk enclosure with disk. I forget what size the disk is. I am also parting out a SUN IPC if anyone wants parts - power supply went (was swapped into a machine that I want to take with me.) I also have a couple of 50 pin SE SCSI HDD with capacities in the range of a couple of hundred MBs. Collect from Cheltenham UK or anywhere I might pass in the UK - which for work means a lot of the UK. I am also happy to ship anything except the E450. Thanks.

Oh, never once have I asserted that. Again the fanboys choose to twist my words in an effort to marginalize any statement disparaging Windows. This isn't about ME, it's about Microsoft fanboys who pipe up and deny the existence of the troubles that damn near everyone has with that product line. This doesn't make ME any better, either in reality or in my own mind. So, envision yourself as someone who has personally cared very much for cars and car technology all your life, has seen such fads come and go, and has a fiscal and professional responsibility to use and sell what works. Now, if you knew of a group of near-religious devotees to a particular brand of car that was widely known to regularly catch fire while driving down the street in nearly all situations, so blind in their devotion that they loudly assert that these failures don't exist when the whole world sees them, how would you react? I poke fun at the Microsoft-can-do-no-wrong crowd (which I was doing at the start of this thread, because Will Donzelli amusingly suggested that UNIX guys don't get laid) because they're very entertaining when they keep pointing at the blue sky screaming that it's red, over and over and over again, ad infinitum, ad nausem. So, no, this is not about me, and I'm sorry, I'm not going to allow you to label it as such. I'm trying to explain myself here, not justify my position...I have no need to do the latter, while doing the former seems necessary when people try to dismiss an argument by restating it incorrectly. In the interest of on-topicness (topicicity?) I will drop this thread if you guys will. I like and respect most everyone here, and I don't really enjoy pooping in my own yard.

You talk about "fanboys" (presumably a derogatory term that includes Richard and me) twisting your words? I think Richard (and I) just said that we're getting a little tired of your endless "Windows is crap" remarks; I didn't hear anyone say that Microsoft can do no wrong, that there aren't any problems with the product line (as there are with pretty well any software), or even that the sky is blue (or red). To use your analogy, if for whatever reason I owned one of those cars you mentioned and had perhaps even made the necessary modifications to prevent it from catching fire, I'd also get pretty tired of your telling me what a PoS it is every time you saw me driving it. What I do read over and over again, ad infinitum, ad nauseam, are your puerile criticisms of MS and dismissive insults of anyone who suggests that their products are perhaps not the complete and total PoS that you keep insisting, not to mention your recurring mention of those 'converts' whom you've shown the true and only way to the light... ;-) Now that *does* sound like a fanboy... >This isn't about ME...

AS/400e 9401-150 server needs a home - metro west Boston, MA

by jpeterson＠chinalake.com

Not really classic in this model, however: I have an AS/400e 9401-150 server and associated hardware that needs a new home. I obtained it last year and do not have the bandwidth to do anything with it. I have not powered the server up, but I was told it works. The front appears to have taken a hit in the lower left (dented grate behind and screw mount snapped--reglued) and the face shows some scrapes. The back half-round cover is missing. I believe the previous owner obtained it 2nd hand for dev work. 2-32 meg mem modules, 2-4.x gig drives (59H7001) se scsi, CD, QIC 4/8 DL SLR5 tape drive, 90H9241 twinax card. IBM 3477 InfoWindow terminal w/ 122 key kb. Found that the power button needs to be pressed down a bit when released (for ON) to have it catch. IBM 3197 terminal sans keyboard--never got it. Term powers up with 0A00 and 'k' on the bottom center. Two lexmark 4028 AS1 laser printers. I have a note on one from last year that the pickup roller is toast. The other says OK, but I will check again. Box of cables. Mostly T adapters or 9 and 15 pin D-subs, one twinax cable, one MAU (really), two terms, one 8-port fan-out (21F5093), and second 8-port fanout (mod# ?), plus a few baluns and odd pieces. There are plenty of Ts, but you will probably need more cable to hook up more than one or two devices. A few misc docs.

I'll keep the printer with the toasted roller for parts if it isn't wanted. Metro-west Boston, MA. Pick-up, or I'll deliver inside the 495 area on my schedule. I will store for a while, if you are really going to collect it, or relay it. --Jim jtp at chinalake.com

P112 kit pre-orders

by dgriffi＠cs.csubak.edu

You've asked me again and again "When will you have more P112 kits?". The answer is "very soon". I'm now taking pre-orders. The kits are $150 for shipping in the US and $160 outside the US. You can place your order at using Paypal http://661.org/p112. If you'd rather not use Paypal, email me and we'll get something worked out. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

HP 9825A

by marvin＠west.net

I've got several HP 9825A calculator/computers that I don't need. In checking out the first one, I get an error code 30 which according to the quick reference means special function not defined. Anyone know what this actually means? As soon as I get them checked out and to a known condition, I'll go ahead and put them up on the VCGM, and start them at around $50 - $75 depending on condition. I've just got WAY too much stuff around here, and I don't expect to ever really want to play with these. BTW, I only get the digest, so I'll see any response(s) on the next digest. Thanks! Marvin

3278s

by wdonzelli＠gmail.com

> Truely boat anchors, but well built boat anchors. There is a variant called 3277 mod 1. It is a small 3270 terminal, with a squished very rectangular tube that can only display 12 lines of text. These were used as consoles on S/3, and are very rare today. Save them if you get them! -- Will
