Modern Marvels: Computers -- Can you identify these items?

by legalize＠xmission.com

I've put up a web page with some screen grabs from Modern Marvels: Computers and I'm wondering if anyone can help identify a few of the items of interest to me. There are links that take you to a web form for submitting info easily if you recognize the items... <http://www.xmission.com/~legalize/vintage/mm_computers.html> -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Free to a good home

by ddsnyder＠zoominternet.net

I have been trying to find good homes for some of my stuff, seems most people prefer to recycle for the metal and plastic. Classiccmp has been a place I watch from time to time, seems I'm always in the background.. So.. I would like to offer the following to the collectors who subscribe to this list. 1. Compaq portable, model 1, dual floppies, software and manuals. Excellent condition. 2. Apple PowerMac, I have to check the model, but has a DOS compatibility card. 3. Original IBM EGA monitor, needs repaired, but is in excellent condition. 4. Two IBM PS/2 Model 25's, fully functional, used at a local college. 5. One IBM PS/2 Model 30, fully functional. 6. Original IBM 83 key AT keyboard. I have other PS/2's 80's, 65, 70. I have to see which ones I have to find a new home for. PS/2 motherboards and hard drives. This is the tip of the iceberg as I really need to clear ALOT of stuff out, but do not want to see it scrapped when I do believe I can find some in the Classic Computer list who may need parts/systems. I am more of a user / collector of DEC stuff, microvax's, alpha station and servers. Send any questions / requests, I will try to answer all Dan Snyder

ftp archives disappearing

by aek＠spies.com

> How are you doing on supplemental files, Developer materials, Programmer's > Workbench, etc.? I have limited email connectivity right now, which is why I haven't been commenting on the recent archiving discussions. Apple development tools are easily found in CD form, staring with "Phil and Dave's Excellent CD" I probably have a complete set, and I'm pretty sure CHM has one as well. Apple Developers CD's also show up on eBay. re: deposition of collections when you're gone contact the CHM registrar (allision akbay, akbay at computerhistory.org) and she can help setting up something if you would like to donate your collection to the Computer History Museum. I'm obviously biased, since I am responsible for their software collection, but I think that artifacts will be taken care of there.

I forgot to include three Centronics printers, models 779, 761 and 781. All are complete and I believe they powerup. I have the service manuals for the 779 and 761. These have been kept indoors in a clean environment since I retired them in the early 80's. I am located in Butler, PA 16001 Dan Snyder

Goodwill Compter works (back on that topic, not bears, etc.)

by jwstephens＠msm.umr.edu

I was holding off comment on this, but today I found out that both of the Orange County Goodwill operations have been "reorganized" and new people are managing them. Luckily, it looks like the people who are in charge won't do anything out front, but there is no telling what the back operation is doing. I think one thing that is stressing goodwill and other thrift stores out here is the "recycling" operations that are picking up at the waste disposal centers here. about 15 or 20 years ago, a friend in Kansas City was a pioneer in the recycling of commercial equipment with the Surplus Exchange. Bruce Holland recognized that a lot of this was just stuff a bean counter wanted off the floor that he was renting and would give it to someone who carted it off. He began taking not just computers but everything not nailed down that an operation didn't want and distributed it to a network of charities for free inKC. In return most of their donations went to the Surplus exchange rather than being turned away. ANyway, now I see that the prices at goodwill for such as 500 to 700 to 1ghz systems is still at the $250 to $350 level, which is just too high. Also a lot of stuff is going to these recyclers, so they are loosing donations, I suspect. Anyway, as to collecting old computers there is probably not that much going to goodwill these days. I suspect most of what comes out are old pentiums, and P2's etc, and it would be pretty hard to get upset with them for loosing the odd old pile in all the stuff they have to deal with. As far as the original posting, from Jim Battle about Austin Goodwill. These operations are not set up to handle a lot of variety in their input. They have to move tons of excess every week, and simply don't have either the trained or sheltered workshop manpower to handle the odd stuff. They are primarily taking the profit the get from any sold donations to hire people with serious life issues, and they will not be spending any money to change their handling of anything, whether computers, antiques or whatever of any kind, but rather keep the basic flow of material going. Wish they could operate in a different way. Even worse, in a town which is the home town it is sad that there is no used computer or electronic surplus store with sufficient business and expertise to take your collectible and sell it, rather than a Goodwill thrift store. These operations are way more endangered now days than used book stores, my other favorite place to get lost in and browse. Ebay for all its flaws is pretty much where you get rid of strange junk these days, or recycle it, unless you are near some operation such as Gateway Electronics in St. Louis, Mo, or whatever similar operation may be around. jim

free for the cost of shipping, from Austin, Texas

by frustum＠pacbell.net

More spring cleaning. Item #1 ------------ For the past eight years I've been keeping a box that supposedly has a B&W CRT in it; it was given to me by a retiring engineer and TRS-80 enthusiast. I finally opened the box and confirmed there is a CRT of some kind it it, although whether or not it is for a trs-80 I haven't checked. I have no need for it; anybody willing to pay shipping on it can have it. It is in great shape and in fact, might be unused. It looks to be about 12" diagonal. There are a lot of different markings on the tube, and I'm not sure which is the most important; in fact, the layout of the markings is such that I can't always tell what goes with what, but I'll try my best: RCA Electron Tube 12VCLP4 Model No. 6 EIA 274 KTR131B Elsewhere it says EIA 1240. Item #2 --------------- I have a heathkit h89 carcas -- it has been stripped of most valuables, but it might have a few parts that someone needs to get their h89 going. Probably the two things that might be of most interest are the CRT and they keycaps. If you want either of those, or want me to check for any other bits on it (mounting brackets or whatever), let me know. It has no floppies and I was told that the electronics had been smoked via an unfortunate application of the wrong voltages. Still, if you want to take a chance, I could pull the cards and let you sort out what might have escaped unharmed.

old terminals...

by RodSmallwood＠mail.ediconsulting.co.uk

I think the keyboards were made up by putting keyswitches into a metal plate then wiring them up in row and column form. A ttl system scanned the rows and columns until it found a closed switch. The count was then equal to the value of the character. -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Tony Duell Sent: 16 March 2007 23:22 To: cctalk at classiccmp.org Subject: Re: old terminals... > > Old terminals > > In the UK in the early 1970's I worked for a (then small) UK company > called Newbury Labs. FWIW, Newbury terminals were common at Cambridge University in the 1980s (but were being replaced by BBC micros running a terminal emoulator). I think they were around at other UK universities too. > We made VDU's or video terminals.

When I needed a replacement CRT for a Volker-Craig terminal (it has an APL cahracter set, which is why I was repairing it), the only way to get one was to buy a cheap protable TV and remove the CRT from it. Nobody stocked the CRT on its own. > We used to spend half an hour on each one fixing up the screen > geometry with small magnets. > > The newer ones used a crude stored program system made out of TTL ie > no Microprocessors. I have a Newbury terminal somwehre. I forget the model, but it's a later one with a separate keyboard linked up by a wide ribbon cable (I think the connections are just the row and column lines of a switch matrix, there's not much, if any, electronics in the keyboard). I've not been inside it for 20 years, but I thought there was a microproceossor in there. I do rememeber a board of TTL incluing some '181 ALUs, though. -tony

If you don't have web or file server, how do you "give back"? What's your ratio of upload to download? - John
