Some of my ewaste finds (Pics included) - Page 5

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

Can you sell it as silver or gold memory, or even rambus?

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!

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.

I got something new today. They came out of a tensator which is something that is installed at the cash registers in dept stores. They look like the mother board from a thin client. Each one had a 256 memory board in it. Each one is about 8"x8" and I was given a box with 41 of these in it.



Heat sinks removed.

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?
