Nice close-up pic's, wish mine were anywhere close to that. Mine looks like I'm taking a picture thru a waterdrop.
Thanks. Two years ago the company I worked for bought me an iphone 4S and they let me keep it when they laid me off. It takes good pictures but the lighting has to be good. I wish it would show the gold plating on circuit boards better but that's probably a lighting issue also.
I've been reading a lot about tantalum capacitors and because I see many on the older telecom boards, I removed a few today. Now my math is not very good but 13 of these caps weigh 0.1 oz.
So according to my math it would take 2240 to make a pound and this particular type sells for $25 a pound. Please correct me if I'm wrong. Also it took me 30 seconds to remove them so at that rate how long would it take me to get a pound.

1 hour 20 min.?
if my math is correct 2240 divided by 13= 172.307692 now that's 30 seconds so multiply that by 2 to get a minute = 344.615385 minutes divided by 60 to get it into hours =5.74358974 hours so about 5 hours 45 minutes if my math is correct
Got a few wireless business phones to add.

My Wife has been stuck in the house for the last 7 days because of the snow and ice and has a little bit of cabin fever. To pass the time she has processed all of the telephones and other things in the garage. Before I left to go to work this morning I told her she could scrap the 14 stainless steel boxes that came out some NEC 2400 PBX's. I thought they were power supplies but they weren't. She called me at work today all excited about what she found inside. Turns out they were CPU's. Here's what she found.
21 memory sticks
http://i52.photobucket.com/albums/g6...b/IMG_1089.jpg
14 CPU processors. 2 were 486's
http://i52.photobucket.com/albums/g6...zeRender_3.jpg
6 long gold finger boards
http://i52.photobucket.com/albums/g6...Render_1_1.jpg
11 short gold finger boards
http://i52.photobucket.com/albums/g6...Render_2_1.jpg
And 14 large socket mother boards
http://i52.photobucket.com/albums/g6...b/IMG_1093.jpg
She was very happy and so am I.
Can you sell it as silver or gold memory, or even rambus?Quote:

Those CPUs look burnt. Those systems must have had some type of overheating problems.
Who cares- it's scrap now!
As for the card reader, I'd assume that it would go as some type of telecom. But, it'll depend on the buyer a lot!
I've been in the garage today sorting and processing more telecom boards from an NEC 2400. All of the cards were bad so they got scrapped. I ended up with a total of 63 boards and 1.6 pounds of eproms. Days like this make up for other days where hours are spent taking phones apart for 1 small mid-grade board.

So what is the difference between that and an IC chip? They look the same to me?
Eproms are ceramic and if you remove the sticker you will be able to see the chip inside through a small window. If you will look on page 3 of this thread I have a pic of some eproms with the stickers removed.Quote:

Heat sinks removed.

Very Cool!!
I brought this home the other day. I didn't really want it but it was full of patch panels and hubs and there was a big battery backup also. Not switches but hubs so that kind of dates it. It was made by the Great Lakes Cabinet Company and is in very good condition. I figure it was made in the early to mid 90's. I'm going to put it on CL and see if I get a bite.

Quick question for ya... In the very first post, what do you guys normally get for phone boards like that?? I think I got screwed last time I sold mine
First card .10 cents a pound
Second card $1.50-$1.70 a pound. Maybe $1.20
Third card $3.40 a pound.
You really need to shop around.
I might be interested in purchasing thosae tensator board with ram for more than scrap. ANy model numbers on them?
Never mind I see you removed the heartsink. Sucks, I had a use for them.
Can't believe I missed this thread. I don't do a lot of telecom stuff, though. (I wish)
Ohhhh the tantalum! Dreamy! Mouse nest cracked me up.
Notification button must be lit up now. lol. Excellent photos, jimi!
p.s. love your old truck.
sorry, your math and others was bugging me lol (junkfreak had it right)
13 caps per .1oz: 130 caps per 1oz: 2,080 caps per lb (16oz)
13 caps per 30sec: 130 caps per 5mins (300 sec): 2,080 caps per 80mins (1hr 20m)
$25 per lb: $18.75 per hr: $0.012 per cap
This is all under perfect conditions of course, boards lined up and ready to get clipped. Like the pics and the updates. Happy scrapping!
I brought home 198 defective Engenius phones the other day. They were headed for the dumpster but I got there in time. 6 T-5 screws and you get a nice board. I just need to buy some more torx bits. I'm missing a few.

I was also able to pick up a 4 cabinet NEC 2000 PBX on the way home. It took about an hour to break everything down. There were about 35 nice telecom boards and 4 back planes. The yellow and copper colored transformers you see on the boards are removed in order to get better pricing. They are very easy to remove and it is definitely worth the time it takes.
http://i52.photobucket.com/albums/g6...502_110755.jpg
I got a couple of those cabinets recently and agree with you on the break down. I would not pay much for them but since I got mine for free I am happy. I'm also happy with the ease of dismantling them.
I have enjoyed reading your thread and the photos really helps support it. Mike
Well thank you Mike. I have a lot more stuff to pick up and some that's just sitting in my garage but I have other things to do right now.
I'm not real happy with the pictures because they don't show the gold plating well. I was watching some videos this morning on how to take good pics for ebay by using multiple lights and homemade light diffusers. I might try that and see how it goes.
I picked up 2 pallets of various telecom and data equipment Thursday from a local telecom business. Everything had repair tags on it and was bad except 1 battery backup. It was an APC SUA 1000RM2U still in the box and never opened. I've been testing it and may already have a buyer for it.

Friday I brought home a van load of boxes full of telecom boards.
The first box weighed 140 pounds.
http://i52.photobucket.com/albums/g6...522_184805.jpg
The second one was 100 pounds.
http://i52.photobucket.com/albums/g6...522_194704.jpg
The third one was 60 pounds
http://i52.photobucket.com/albums/g6...522_194829.jpg
I still have about eight more boxes to unload and sort through. Got to find room in my garage because there's more stuff they want to get rid of Tuesday.
Oh my GAWD.. LOVE IT.. Love those boards. They look like really big $10 bills!
;)
I'm loving it.
The IT guy came to my desk yesterday and said he had another box for me. I got 7 pounds of gold finger cards and 10 sticks of RAM along with 4 power supplies PC fans and heat sinks.
I also found about 10 of the 2500 style analog phones and about 10 handheld scanning devices in the dumpster. I'm interested to see what is inside them.
Overall not a lot but it's adding up.

Got to like the "IT Guy" feeding you the good stuff, take care of him!
Yeah, I try to take care of him and others at the shop also. I ask him and others that if they need anything let me know. I have headsets for phones, power strips and power cords, dry erase boards and I've given a few people monitors for their PC's at home. Everybody knows that I recycle electronics and many give me their old broken stuff. I got 4 more towers today from the IT guy and about 25 digital phones from the warehouse guy.Quote:

My focus has been on the ferrous side of scrapping. In time I became educated in some of the non ferrous metals because of what has been shared on this forum. Now it is time to learn more about ewaste and your thread has been very valuable. I enjoy the pictures and the insight you provide. Thank you.
I wanted to show a quick breakdown of 2 scanners I got the other day.
http://i52.photobucket.com/albums/g6...617_044211.jpg
The hardest part was trying to figure out how to get the things apart. Both had some nice boards and gold plated contacts for the batteries and touch pads. The reflectors in the laser part looks like gold plating. I wondering if the laser part could be used for anything.

I remember someone saying last week to always keep an empty truck. I've always tried to do that even if it means unloading at 10 pm.
I was on my way home from work Thursday last week and got a call. I was about 3 miles from the business that called and thankfully my van was empty.
I ended up with 4 PC's, 1 Cisco router, 8 keyboards, 11 monitors, 16 printers and a big box of cable.
The PC's are Pentium 4's with XP and will be scrapped. I believe all but maybe 2 monitors work so I'll keep them and try to sell them.
http://i52.photobucket.com/albums/g6...628_065939.jpg
I'll tell you right now, I don't like printers but I have to take it all especially when it's free. I give the printers to my neighbor after I remove the circuit boards. He puts them in with his shred.
http://i52.photobucket.com/albums/g6...628_070040.jpg
These are the boards from the printers.
http://i52.photobucket.com/albums/g6...628_095105.jpg
I was able to pick up a few things the other day on the way home from work.
5 printers, 5 laptops and a small NEC phone system with 12 phones.
http://i52.photobucket.com/albums/g6...701_202107.jpg
Also a NEC 2400 PBX, rectifier, batteries and a box full of copper wire.
http://i52.photobucket.com/albums/g6...701_202028.jpg
I wanted to do a quick breakdown of the NEC 2400 PBX from my last post so you guys can see what's inside in case you ever run across one.
Front view showing the circuit boards. The 2 boxes on the bottom right are the redundant CPU's. It also had redundant power supplies but a direct lightning strike makes redundancy a moot point.

One of the 2 CPU's
http://i52.photobucket.com/albums/g6...719_092227.jpg
Each CPU had a large socket mother board, a green fiber processor, a gold finger card, 2 sticks of gold ram (not shown) and a few other boards.
http://i52.photobucket.com/albums/g6...719_092435.jpg
I had to remove the bottom bay to gain access to the internal wiring.
http://i52.photobucket.com/albums/g6...719_095645.jpg
This was a small portion of the wire removed. There was about 50 pounds total.
http://i52.photobucket.com/albums/g6...719_095731.jpg
Almost 70 pounds of gold finger telecom boards ready to be boxed up.
http://i52.photobucket.com/albums/g6...719_104733.jpg
And 14 pounds of back planes.
http://i52.photobucket.com/albums/g6...719_105140.jpg
Total time spent was about 4 hours but that included taking pictures and creating this post.
This is the operator console that went to the NEC 2400 PBX I scrapped in the post above. Nothing spectacular but I wanted to see what was inside and thought I'd share.

Any chip thats made in short runs, gets used intentsively, is military, or keeps people alive or such, weather forcasting, number cruncher, deep pocketed buyer, corporate, NASA or security, programable, is made to a higher standard.Quote:

Now those EPROMs are programable. They have a little window above the chip. When they want to blank the imformation on the chip, they expose the chip to a bright UV light for a while. Somehow that blanks the chip. (now I have to find out exactly how..)
By looking thru the window you can see if it has Gold or Silver wires going to the chip itself, from the legs.
The Gold wires makes it worth more. But even Silver wire is worth more than in normal chips.
Also, under the chips they paint little splash of Gold or Silver paint before they mount the chip. This acts as a heatsink for the chip and makes it worth more too.
So divide up your EPROMS into these 4 catagorys, Buyers definations can be different from others too. So it pays to be thorough anyway.
If you find any odd ceramic chips, like a 'double stacked' chip (a smaller chip plugged into the top of the larger chip) its woth good money to a collector of chips (hobbyists)
Same goes with finding a board covered in these purple or white chips. More$$$$
Wow, those back planes and telecoms are amazing, jimi!
Thanks for sharing the great pics. Love this thread! :)
