ASCII art spam

by tomj＠wps.com

Spammers have "invented" ASCII art. There's three curious things about this. One, it of course gets through text-matching filters. Two, it retroactively ruinates real ASCII art (if this catches on, seems most unlikely). Three, is there a drawing program for this?

"Antique" Apple II e Computer, Manuals, Books

by jesnyder＠iastate.edu

Greetings While doing some housecleaning, I re-discovered an old Apple II e computer (with monitor, disk drive, and keyboard), and a big box of software, manuals, and books for it. I am not a home computer hobbyist (just a computer user) and have no use for it, but it would seem a shame to just throw all the stuff into the dumpster. I am not really trying to sell it or anything, just see that it gets to someone who is interested in it. How can I find if there is someone interested in it, who I could give it to? Thanks for your help, John jesnyder at iastate.edu (515)-294-4312 (university) (515)-232-8824 (home)

plastic "push rivets"??

by jwest＠classiccmp.org

I'm not sure what these things are called... but I need some. I'm calling them plastic "push rivets", where a plastic plunger pushes through a collar with 3 or 4 plastic legs. These legs break off. All the ones I've seen so far are a pretty common size. However, the ones I need two of at the moment are slightly smaller than that. Specifically, these are the two plastic push rivets from an HP 264X terminal that hold the metal cover over the CRT. Anyone ever find a source for these? Both my local electronics places came up empty. Regards, Jay West

To inject into the line it's fairly trivial to make an RS232 level OR gate! For general listening MY VT320 in display controls mode does well enough. Allison

Apollo 340 machines (Manchester uni, UK)

by julesrichardsonuk＠yahoo.co.uk

Chap at Manchester uni has three Apollo 340 machines (plus assorted spares by the sounds of it) which are heading to the skip today. I've been trying to save these for a couple of weeks but it's just too far away for anyone at the museum to make a dedicated trip to collect them, and none of our people get up to that part of the country very often. Maybe someone local can rescue them instead (or even can hold them on our behalf for a bit!) Shout if so anyway and I can give you contact details - maybe they can be held in a room somewhere for a few days if someone's definitely coming to pick them up. These are early Apollos so it'd be nice to save at least one (earliest ones we have are DN3500 and DN3000 machines) cheers Jules

There is no "there" there. There will always be tremendous variation in regional density of particular items, and this necessarily affects the price, which is why arbitrage flourishes on eBay. I've never seen most of these BBC micros in person, for example, but I'm sure they're quite common across the pond. There may have been a couple dozen Teraks at a half-dozen universities around the US, but they may not have ever existed in other areas of the country. You have to consider where the items were commonly sold as well as where they were commonly scrapped. - John

MOS Kim-1 Any idea of it's worth/value?

by us21090＠yahoo.com

/* coming out of the shadows.... */ I'm planning on exhibiting my MOS Kim-1 at the Trenton Computer Festival (http://www.tcf-nj.org) and it occurred to me that I don't know what this computer is worth (whatever "worth" means). **** I'm not interested in selling it **** My Kim-1 works and is a Rev B MOS unit, with original blue-cover manuals (as well as home brew case and a home brew 2k memory expansion). The only data point I have is a recent ebay auction, where 2 working Kim-1s, nice enclosures, Kim Extender Interface, 4 memory cards, S100 breadboarding card, issues of "Micro", etc went for $642. The item description doesn't mention Rev #, or even whether its a MOS or Commodore (though the photo shows *white* manuals). So... roughly $300 for a Kim-1? Thanks!

Ebay Poll, was Re: knowledgebase request

by marvin＠rain.org

I love the concept, and don't respect the people running it with the policies, distortions, and outright lies they seem comfortable with. Ebay has its uses, but the main one is to allow people who are either ignorant of or are too lazy to work with other distribution channels. Hmmm, maybe most of us :). I've gotten some great deals there but for the most part, there is too much "noise". I've sold some stuff at good prices there, but my belief is that it is for the most part, really only of value for higher end products ... say $100 plus. > > From: "Randy McLaughlin" <cctalk at randy482.com> > > Maybe we can have a poll to see who likes ebay , who hates ebay, and who > aren't sure :) > > Personally I like it, while it can drive up prices for things it has also > caused others to auction them instead of dumping them. > > Greed has saved many systems that would otherwise be scrapped.

2 IBM 3277-2 available [EU]

by cbmpet2001＠yahoo.de

Dear IBM-Users, I have 2 3277 Model 2 (those with the larger screen) from late 70's available for free. The units should work (I couldn't test them so far) and are in very used condition. They come from scrap, I could not see them out there. I will look out for keyboards and am sure that I have at least two spare. Please note: These Units aren't really pretty to look at, but the logics seem complete. If someone want to have them it'd be best to pick them up at my office. I would ship, but thats a bit expensive. It's also possible that I get them into my car and drive a bit. If interested, please contact me by mail, best regards, Wolfgang Eichberger PS.: I have a small Siemens-Terminal (Serial - comes from a DEC P9000 Unix environment, complete) too that I am willing to part with. ==================================================== Ing.

On one side are the ePayers who buy retail and on the other side are those like Sellam who are on the wholesale side of the market (not to imply that he is a dealer, but he sees things before they get to retail, from sources like: scrap dealers, institutions etc.) It is just like when you go to the auto dealer to find out what your trade-in is worth, he looks in his red/black/blue book and gives you what seems like a stupidly low price. Those prices often come from wholesale car auctions and reflect what the dealer could source cars for. He is not going to pay retail price as he wouldn't make any profit from it. That leaves you to sell your car privately if you want to get the "retail" price. But both the car dealer and you see a "market" from different points on a continuum. As I don't live in Silicon Valley or anywhere with a history of "high tech ", I can only use eBay to access the "market". If I did live there, I would have access to many more sources (that's why I'm going the the next VCF!) Conclusion, the market isn't just end users or middlemen, it's both, but they pay/get different prices!

I have a couple of simple serial datascope packages in my Labtools ... I don't supply cables, I just give details on how to make them. Basically, there are two sets of signals to monitor, one going from DTE -> DCE, and one going from DCE -> DTE ... What the "Y" cable does is simply connect the DTE generated signals to the input signals on one COM port, and the DCE generated signals to the input signals on the another COM port. The software reads the two com ports and displays the two signals paths in a standard dual/split line format, with DTE signals on one line, and DCE signals on the other. (Since PCs are DTE's, the input signals to the COM ports are the DCE lines at the PCs serial connector). The DTE signals (outputs) from the PC COM ports are not connected, so the PC does not drive either side ... it just passivly monitors the traffic on the line. For short runs at the speeds commonly handled by a PC serial port, the extra loading of the passive receiver is usually not a problem. One limitation of this approach is that the PC cannot interact with the devices. Some stand-alone/higher-end scopes feature simulation, injection and other features which require that they be able to transmit on the line in specific circumstances these usually have their own set of line drivers and receivers, and act as a simple repeater during passive monitoring.

Unix on old-ish machines - advice sought

by stanb＠dial.pipex.com

Hi, I'd like to get a straight (ie no X) Unix running on some sort of older, but not necessarily ancient, hardware. My Micro-11/73 is not really suitable, and PDP-11s that are seem to be a bit thin on the ground over here in the UK. I've seen a few Vaxen and MicroVaxen on the market lately so my thoughts are turning in that direction. I know a few people here run such machines and I'm seeking advice on the best machine to look for and, at the risk of starting a religious war, the best unix to run on it... :-) TIA... -- Cheers, Stan Barr stanb at dial.pipex.com The future was never like this!

Intel offers $10, 000 for Moore's Law article Firm seeks pristine copy of founde

The Santa Clara chip giant has posted a $10,000 bounty on eBay for someone who can provide a pristine April 19, 1965, copy of Electronics magazine. That issue of the magazine contained an article by Intel co-founder Gordon Moore that described how the number of components on integrated circuits was doubling every year. The article became the foundation for his famed dictum. "We have photocopies of the article but not the actual issue of the magazine," an Intel spokesman said. "Gordon doesn't have it and the Intel Museum doesn't either." Electronics magazine went out of business several years ago. Intel turned to the online auction site on Monday, posting a message on eBay's Want It Now page offering $10,000 for a copy of the magazine in mint condition. (The company may buy more than one copy but at a lower price. Intel employees and their families are ineligible.) Moore's Law -- which has since been revised to estimate that the number of transistors doubles every 18 months -- has been the cornerstone for the information technology industry for decades as it has defined how products can simultaneously drop in price while improving in performance. This has created a situation in which users upgrade well before their equipment breaks, a boon for the industry. Despite its historical significance, the article at the time wasn't considered a monument. "I didn't think it would be especially accurate," Moore said in a recent interview. Moore, 76, was born in San Francisco and received a bachelor's degree in chemistry from UC Berkeley. He was research director at the Fairchild Semiconductor division of Fairchild Camera and Instrument Corp. when he wrote the Electronics magazine article in 1965, and in 1968 he co-founded Intel. Chronicle staff contributed to this report. Page D - 1 URL: http://sfgate.com/cgi-bin/article.cgi?file=/chronicle/archive/2005/04/12/BU…

You people REALLY need to start paying attention to emoticons and learn to read the sarcasm between the lines. :-p The point was a joke. Collateral damage causing loss of email with spelling errors was supposed to be a good thing. Following the same JOKE logic, loss of any email that I can't understand (including other languages, mathematical formulas, or most everything Tony Duell talks about since it all goes way over my head), may also be good thing. ;-) Besides have you interacted with anyone under 18 via email recently? Maybe filtering on spelling errors IS a good thing! =:-O :-) (watch out for those emoticons, they are the only way in email to point out jokes and sarcasm). -ps: this email was spell checked by Claris Emailer 2.0v3 that doesn't know "email", "spam", "emoticons", "Duell", "ps", and "2.0v3" are all acceptable. -chris <http://www.mythtech.net>

I don't know what they go for, but I bought two for LaserJet 4's (not L, one was a 4 the other a 4 Plus), on ebay for around $10 each (I bought them about a year apart from each other).

credits for knowledgebase faq entries

by jwest＠classiccmp.org

Oh, by the way - some may consider this not terribly important, but I like to be a stickler for such things. I put some initial entries into the ClassicCmp knowlegebase straight from the FAQ. I also contributed an article or two of my own. The entries that I took from the old ClassicCmp FAQ were posted with an author of "Jay West (FAQ)", and the ones I wrote myself have an author of just "Jay West". In the original FAQ, there was a list of credits to people who came up with some of that information. I would like to put a "Credits" link on the knowledge base website, that lists and thus gives credit to these people. I am not an HTML programmer, I know barely enough to change single lines of existing HTML. Would someone with basic HTML skills be willing to create a credits hyperlink on the knowledgebase site, that presents a separate page listing those people? If so, please contact me off-list.

Exciting news about ClassicCmp and the Vintage Computer Festival

by news＠computercollector.com

Hi cctalk'ers, I don't usually send list-wide updates, but this is a special case. Without further comment, here are two articles from this week's issue of Computer Collector Newsletter. - Evan ----------------------------------------- New: The ClassicCmp Knowledge Base An extensive knowledge base is being added to classiccmp.org, the web presence behind the popular cctalk and cctech mailing lists. Users will populate the database with their own submissions, such as system information, technical tips, and advice for finding, repairing, restoring, displaying, and storaging vintage computers. All entries will be moderated, but registration won't be required. The database will be searchable by category and keyword. The database is located at http://www.classiccmp.org/kb and an email interface is being developed. There are already some starter entries based on the mailing list FAQ and independent contributions. Comments to these entries are encouraged, although the knowledge base is meant to augment, not replace, the mailing lists. - Jay West, classiccmp.org moderator --------------------------------------- VCF changes and new shows being planned Changes at the Vintage Computer Festival are creating new regional editions, starting with VCF Midwest 1.0 next month. We reported on Jan. 24 that VCF Midwest 1.0 was tentatively planned for late May at Purdue University. The details we expected for the following issue didn't materialize, but now the weekend of May 28-29 is a near-certainty, show planner Patrick Finnegan said. Whether it's a one- or two-day event is not yet determined. It will be held at Purdue's Stewart Center. (We'll share more details here are soon as they are available.) VCF Midwest 2.0, in 2006, may be held in the St. Louis, Missouri area. VCF East 3.0, originally planned for this summer in the Boston area, probably will be delayed until spring 2006. It may be organized by MARCH - Mid-Atlantic Retro Computing Hobbyists - which is a new club based online at http://groups.yahoo.com/group/midatlanticretro/ . VCF Europa 6.0 remains unchanged. It will be held April 30-May 1 in the Munich, Germany area. See http://www.vcfe.org/E/ for details. Our own Sellam Ismail, who founded the VCF in 1997, will continue to personally run the main VCF event each fall in Silicon Valley. - Evan Koblentz, editor ----------------------------------------- Evan Koblentz's personal homepage: www.snarc.net *** Tell your friends about the (free!)

IBM 2501 card punch offer/salvage

by mapleleafman＠gmail.com

HI folks, I got an email this morning offering this piece of IBM equipment, 2501 card punch. Generally I forward these emails to my own list of collectors but for this particular piece I decided it needed a more general audience because the unit is in Newfoundland. No roads to our newest province so container shipping is required. Here's the whole text of the original email : _ Do you know of anyone who may be interested in the above?. It is currently in storage (garage) in Newfoundland. 1970-1980's. 2501 Card Punch. Also have a humidity reader used in early days to measure humidity in computer rooms. Thanks Marie _ Marie's email is : mhussey at hfx.eastlink.ca The humidistat sounds smaller, at least! If this isn't worth salvaging for anyone in our world, Marie mentioned in her email that she would junk it and save a part for old times sake, as she used to work with it. Maybe someone could give her an idea of what part(s) would be either interesting for historical purposes or maybe to replace parts that they require and would be smaller to ship. Marie lives in Nova Scotia so she can't exactly duck out to the garage to have a looksee either. Contact her directly as I don't check this email as often as I probably should. Brian Mahoney _______________ The list I maintain is here: http://www.geocities.com/computercollectors/ If you want to be on this list please email me at : antique101 at hotmail.com NOT to the list or this email. Say please and thank you and give me a good email and we'll get along famously! _______________
