How Much Gold and PGMs and Silver is in Vintage Boards?

[mmzhr]

Hi guys
I found these vintage boards in scrapyard
how much gold and pgms and silver is in these boards?

Those white ceramic chips may have a collector valve beyond their gold value. Look the part numbers up on eBay or equivalent and also check the "sold/completed" section.

hi friend
i know
so how much they worth for collector value?
how much gold i can recover from all chips and gold fingers?

cpu part number is unknown
i not found any information about this type of cpu

I'm not sure because I'm not a collector, but there are a few forum members that might have more incite on they're value.

Those chips look awesome though.

thanks for reply but how much gold from all chips?

How long is a rope??
You are asking a question that can not be answered in a meaningful way.
We know nothing about the actual size of the plated areas, the thickness of the plating.
And unless someone has processed a full batch of these components, which is unlikely,
they will not know the yield of the components and cant give you an answer.
The traces on the boards are Tin covered so there is no Silver there and my guess will be no PGMs.

i know it but this chips are rare
i want to know approximate value of gold in chips and boards before i scrap or sell in ebay

And that is the reason you will not get an answer, because nobody knows.
The value of rare boards/chips are not in the PMs but in its rarity.

Those are boards from one of the old Burroughs computers. I don’t know the model, but some of the sold EBay auctions said the boards came from a B800. I’ve seen them on EBay a few times now, and they normally sell for more than I’d guess the value of their gold content might be. I’ve also seen just those square white&black chips sell on ebay before for around $40 each. If you search there for Burroughs CPU and check completed items, there are still a few closed auctions showing. This was probably the best deal, somebody got 11 boards for $136 and there were 18 of those chips between them. It may be too expensive for gold recovery, but if they took their time they could probably triple their money by selling the 18 chips as collectibles. Then process the boards and other gold capped chips also.

As I and many others have said before the only yield that counts is yours , depending on your skill equipment and processes it can vary greatly , others results may give you a guide but only that.

hi bro
that's amazing!
i searched whole internet and social media but not found any information about these boards and cpus
thanks for information
god bless you

hi bro thanks for reply

I pity those boards, they should be in a museum. You can surely get more than the gold value in collector value,

If you take in account that the best recoverable chips offer a few grams per kilo, these boards to me, given the amount of material are more keepsakes than recovery material and after I've enjoyed seeing them I sell them off.

If you can sell each chip for $40 on Ebay, then it's probably MUCH better to sell them that way. The absolute highest yields for chips I've ever heard of was about 1 gram per chip, and those were old aerospace parts where they had to work PERFECTLY every single time and endure lots of bumps. You won't find anything that high on any consumer electronics.

This museum in RI is really extensive, I got the grand warehouse tour when I donated one of these huge IBM 9335 hard drives for posterity.
(still have 2 more):

Good old stuff.
I believe those yellow capacitors might be the right mlcc for a little bit of palladium maybe.
Should be non-magnetic variety.

IBM used a lot of both MLCC‘s and (2,3, and 4 pin) tantalum capacitors on those type boards. The 2 pin tantalums are not always marked with the polarity either, so they can be hard to tell apart from the MLCC’s. I’ve stripped a lot of IBM boards and made up my own list of the part numbers as I found new ones. At last count I had 13 different part numbers for the tantalums and 81 different part numbers for the MLCC’s. Both the MLCC’s and tantalums can also be either black or yellow. I also made up a list of resistor network part numbers since they used a ton of those too. They actually used a few single resistors in those 2 pin molded packages that could be confused with MLCC’s’s, and had at least 28 different part numbers of 4 pin resistor networks that could be confused with the 4 pin tantalums. There was only one part number of 4 pin tantalum that they used though, #5615372.
