Gold Finger Cards as in $2.90 Per Pound?
Funny thing, I was looking through other posts as I want to learn about this stuff, I am a 53 yr old lady and I love to still tinker with things, so learning all this is fun. I was looking at other post and seen in one of the post that these were batteries, thanks for confirming that for me as I was not trul;y 100% sure. I will take them off before I sell them.

Yes. Gold finger card at $1.90 and telco at 3.50

These are totally different from standard ram cards.

How can I tell if the First set of photos work, as that is a really nice price and would cover the price of all I bought plus more.

Sorry just seen this, there is nothing on the other side of the cable one (2). I don't what tiny board you mean would be Telco, on the (2) one

You need to hook them up to, and/or plug them into whatever their intended situation is. Given what that stuff is, if you're asking you probably don't have the equipment to test it. That's all rack server equipment.

The itty bitty board bolted in above the att dc box.

Look up rack node or server node on ebay. You may be able to sell it as is for parts as well, for that first board. The rest of it is better off as scrap for you if you have any doubt.

Thank you so much you are a wonderful person to help like you do, I will do just as you say and see what I come up with. I took all the metal off the (2) already, the total weight of the stuff I picked up was over 850 pounds, there was a lot more goodies in those boxes. And no I have no idea how to test them, my husband (24 years of recycling metals)and I run a Metals Recycling Plant, and we just started taking in computer components, boy is this fun, I love the computer part of it, that is going to be my specialty. I am learning lots from you, thanks so much.

The fastest, though by no means easiest, way to learn is to teach yourself. Hang on to one of these thingamajigs and one of those whatamados and try to buld a frankenputer. The first time you get the beep beep ding from a 1985 junker of broken and cast off parts you'll feel the second best moment of your like (following marriage and before children)

Hahahahaha you are right, I would probably jump up and down and look crazy yelling "Look what I did" . But that sounds like a great idea, all I need is power and there will be no stopping me. LOL I will have to search around this site for ideas.
