fleabay has been good, i have been selling one pound lots of (unknown gold content) for $20 to $36 a pound

i never tested the gold content & the manufacture does not give out that info (i emailed them directly)

i have a total of 260 pounds that i paid $0.73 per pound for, next i am going to try putting up 2 PP CPU

i picked up this lot for $20.00 last week

it was a good score, good thing was i was going to make an offer but asked the guy what he wanted for them :shock: 20 bucks :shock:
 
That was my auction they sold for 2500.00 plus shipping. We have sold over 200 lbs in the 75 dollar per lb range in the last few months.
 
Yes, there is one nice example of the C4004 in that lot with the possibilities of more but lower grade.
 
You must be correct, the only thing that makes sense is if they were bought as collectibles. Still their condition is terrible though, and only maybe a third of them are even Intel chips. I guess I should have looked closer, I was just assuming they were ram chips based on general appearance and the small packages. A lot of sellers try to call all chips processors anyway, whether out of ignorance or just pumping up interest.
 
About $200 worth of gold for the 150 parts. The guy that sold these on eBay said:
That was also back when they didn't really know what they were doing and how much gold they were supposed to use.
A common belief that is total BS. They knew exactly what they were doing and how much gold was required. There was about 45-60 micro" of gold used on those parts. These same packages are still made and the gold thicknesses are essentially the same. On one spec sheet I found from a present day manufacturer, they use a minimum of 52 micro".

I give the seller credit for his imagination anyway and his obvious ability to reel in the suckers. He also claimed that they allowed workers to smoke in the factories back then, and inferred that they were smoking pot so didn't know what they were doing and they used too much gold! Obviously this guy has no concept of what a clean room environment for semiconductor manufacturing looks like?
 
The prices for the 4004 are rising and are worth a lot of money to the particular buyers.
I have some Intel 4004 , 4003 and 4001 and I have been offered an arm and a leg for them even though legs are bent. There are some 4009 and of course the 8080 that are similarly high priced.
I suppose I should put them in a safety deposit box.
 
This is the largest collection of very rare chips that I have seen. If the condition is decent
they may bring in excess of twice what the buyer paid to collectors. There were multiple
C4004's and many other very rare chips.

Wake up people!!! I make more selling chips to collectors than I could EVER hope to by
what I could get from refining them for their gold content. But then again I don't mind
selling them in small lots as I am saving part of the computing heritage that is being processed
and refined now.

I enjoy doing some refining and I greatly appreciated learning about how to do it but I have found
that for me at this point in life, selling the e-scrap and saving the rarer chips from an acid bath
is what floats my boat.
 
When I first looked at the auction. I looked to see what style of chips they were.

Yes they do look rough. Whoever bought those will clean them up best as they can. Hold on to them for 4 or 5 years and make double their money back.

The price paid doesn't surprise me. In 5 years people will pay big money for those chips even if the don't clean up very well.

Aristo if I had those chips they would be in a safe deposit box or a big safe that only I had access to.

Like glorycloud said check your chips and other gold plated components sell the best and refine the rest.
Just by that auction everyone can see that condition doesn't matter sometimes.

When I first saw the pic's, those were the first I looked for... I counted about 7!

I look for rare ones, too! I just received 7 of these Nortel Networks CPU's; I've never seen them before and they will make a great addition to my collection!

Just to be a bit specific... those are not CPU:s, it is some kind of microwave circuit, probably a filter or an amplifier module. The dead giveaway is the wave guide that is passing through the module and that the size of the wave guide isn't changing (no change in frequency).

Nice module though.

Thanks for the correction! 8)

The person I bought them from referred to them as, "...CPUs were taken out of Nortel Networks fiber optic equipment", and "telecom processors", so I just called them cpu's. And yes, they are beautifull indeed!

Thank you gentlmen!
