Intel i2920 IC was Re: Intel Intellec 8 computer?????

by amichael＠nortelnetworks.com

I also recently came across one of these Intel SDK-2920 single-boards, but it's missing the 2920. If any 2920-equipped list member is interested in giving this board a better home, maybe we can arrange a swap. Arlen Michaels > -----Original Message----- > From: Richard W.

Gold price was: Re: ebay feedback

by xds_sigma7＠hotmail.com

Damn, maybe I shouldn't be tossing crud like that busted VR290 in the dumpster... All of those 14" monitors are worth 3 to 5 bucks? Heck, I've probably tossed 20+ of them this year... As I write this the dumpster by my work contains 2 dead terminals, a dead VR290, and Dell guts.. the MicroVAX 3100 may, unfortunately, be joining them soon, since it won't boot and all I get is a ~ from the console :( But seriously, would it be worthwhile to save all the circut boards, monitors, etc. which I currently toss in the dumpster? I already have a bunch of automotive scrap that I know is worthwhile (i.e. engine blocks, transmissions, etc.) but is that computer junk worth it?

11/23 CPU

by Rdusza＠ci.manchester.ct.us

Is there anyone who knows where I can purchase an 11/23 CPU for an existing Computer that we use to run some process equipment here in town. We had a major failure of one of the processors and donot have any spare CPUs. The system is due to be replaced next month. I also need a name for repair of existing cpus if possible.

Probably MUCH safer to place the CRT in a thick cardboard box and tap an ice pick or awl through the anode connector. -----Original Message----- From: Peter Joules [mailto:peter@joules0.demon.co.uk] Sent: Tuesday, December 07, 1999 7:06 AM To: Discussion re-collecting of classic computers Subject: Re: Gold price was: Re: ebay feedback In article <m11v9t8-000IyJC@p850ug1>, Tony Duell ...looked dangerous to me so I used the 'blanket and brick' approach as in (c) above or put the tube in a dustbin and crouched down beside the bin and used a hammer to knock off the neck keeping the bin between me and the CRT. -- Regards Pete

I know this business well, having apprenticed to a scrapper for several years. He is lowballing you on prices. This is common among scrappers. However he is fairly accurate when you include labor. Final prices depend on the price of the metals that day, remember this is an international market. > > Breakage, what it sounds like the lowest grade general scrap, 2 to 4 cents/ > lb Breakage breaks down into three categories (actually more if you consider specialized breakage like telephones.) Low grade breakage is 2 to 4 cents per pound. Motor breakage (must include a motor or transformer) is 4 to 6 cents per pound. Aluminum breakage which has a high content of aluminum mixed with other metals can be up to 16 cents per pound. IBM 3380 disk drives have the aluminum platters pressed onto a steel shaft. The difficulty of separating these pieces make them Al breakage. > Cables with copper inside, power cords, data cords, etc. 6 to 8 cents/lb Wire is graded by the amount (%) of copper in them. It really pays to sort it and remove the connectors. The last wire I sold ran from 12 to 24 cents per pound. The connectors stripped of their housings and excess wire can bring up to $2 per pound > Old PC chassis that have some usefull parts, drives etc., but maybe no cpu > or memory chips. 8 cents/lb Old PCs have little value. My friend who is shipping containers overseas is getting $10 for every 486 or better box he throws in the container, they must have CPU (33mhz or better), memory and drives. They do not have to be tested or working. Anything else is steel scrap or breakage. > Just the circuit boards, 25 to 35 cents/lb Raw PC circuit cards are this price. Raw dec cards are worth considerably more. However it pays to clean the cards. If you remove the metals on the card (this includes the aluminum capacitors then the cards can be worth up to $1.50 a pound at the refiner. The last cards I sold I got $1 per pound for run of the mill and 50 cents per pound for clean PC cards. This was at the bottom of the gold market. However I get top dollar because of the job I do to clean them. The last DEC cards I sold I got $1.33 per pound. This is after all of the collectors in the area went through them and pulled anything they were interested in. Gold plated cards like the HP are worth up to $3.50 per pound. The brighter the gold the thinner it is. Circuit cards from before 1972 have gold that is much heavier plated. This is when gold was $35 per ounce. The plating was normally 40 microns. HP plated cards from the 1980s had gold at about 1 micron. These cards have to be evaluated separately It also pays to clip and collect the Tantalum capacitors. They are very heavy. The last I sold I got $4 per pound. > Aluminum that a magnet isn't attracted to. 35 cents/lb The price of Aluminum fluctuates daily. The last prices I got were .37 for painted sheet, .39 for unpainted sheet and ,36 for cast. 6061 extruded is about is about .42, 6063 clips are about .44 and 6068 disk drive platters are worth a premium. If there is any iron or other contaminates the aluminum goes as irony Al (less than 2% iron by weight) or breakage. There are other metals of interest. The water cooled mainframes have a lot of good copper that will bring 70 to 80 cents per pound. Electromagnetic shielding, called Mu (pronounced moo) metal has a high nickel content and ha a value based on the daily price of nickel. Also ALNICO magnets have a fairly high value for similar reasons. These come out of the CDC 300 meg removable disk drives and others. Stainless steel is highly prized because it is heavy and worth about 20 cents per pound. The last major metal salvaged is Palladium not Platinum. It is used heavily in computers. IBM mainframe cards demand a premium because of their use of Palladium. Some keyboards have gold contacts in them. Backplanes are usually Palladium or Gold. Big printers usually have a heavy cast Aluminum base plate. I am not mentioning the value of some of the chips on the cards. Any ceramic chip has a gold value. All plastic chips have a breakage value, even preprogrammed pals. A lot of this varies by the year of manufacture. > Untested or bad monitors > 14" about $3 to $5 > 15" My friend who ships containers overseas is getting above market for monitors. If they are at least SVGA he is getting $10, working or not. He can put up to 200 in each container. Now the minimum weight he has to get into his containers is 40,000 pounds, so he can't send too many. > 17" > 19" More, but it isn't clear how much, as testing/repair becomes more > worthwhile. He is getting $20 non-working for the 19" monitors in the container. Most of his large monitors he has serviced and sells them locally. One consideration in the prices you were quoted was labor. To evaluate a computer system you total what you will get for all of the metals then deduct for the labor to take it apart to get the metals. Many scrappers will work on a profit margin of 2 cents per pound. If they feel they can drive you from the market they will bid more than scrap if they have to. It is better to make friends with scrappers so you can make deals before the sale. We are thinking of making a video tape about evaluating scrap and another about loading containers. Anyone interested? Paxton

Nostalgic note [Was: Re: Amiga 500, 2000 serial ports: The same?]

I got my A1000 in 1986 and an 8-bit ISA adapter called The Wedge in 1987 to attach a WD-WX-1 w/ST225 disk - 20Mb for $500; it beat the $1000 that a "real" disk was going for. I later went from using The Wedge to using the "Golden Gate II" card in my A3000 for Ethernet - it's a Zorro<->ISA bridge card to let you use IBM cards with Unix and AmigaDOS. Eventually, I bought the design and made a bunch of them under the name "GG2 Bus+". > At that time, I thought about getting an A3000 w/Emplant (so I could > run Mac DTP programs), but decided on a Mac LC III instead. . . I went with the A3000/A-Max route - Localtalk for the Amiga and I could hook my computer right up to a Mac-compatible laserprinter. It's still set up at my right elbow, but I don't use it much anymore :-( I've gone >from M$ Word on an emulated Mac to M$ Word on a Windoze box. Foo. This is not progress. I just went to our Amiga club's December meeting/party... a dozen people. At one point, AmiCON, the third registered Amiga user group in the U.S., had over 300 members. It was a real world example of how far the Amiga has faded away. If there are any Amiga users out there who are still using their machines for "useful work", I still make the "GG2 Bus+" card. It comes with Ethernet, IDE, serial and printer drivers and is *very* well supported under BSD-flavors of Unix on the Amiga. Write me off the list for details. -ethan ===== Infinet has been sold.

Well - that confirms the PSU question. I don't know what a "panel box" might be, but it was possible to hook an older ONMIBUS cabinet to an -8/a with a pair of cables that superficially resembled UNIBUS cables. Want to sell the RK8E? I have a couple of drives, but I'd need at least one 16-sector pack, preferably a couple. I don't really need any hex-height OMNIBUS core; I've got a KT8-A and a 128Kw MOS board. I'm still looking for a programmers console, BTW. -ethan ===== Infinet has been sold. The domain is going away in February.
