Telefunken, Germany

Not sure what it is though

Interesting. I found these in a box at an attic in Heilbronn, Germany.
So that Heilbronn plant must be the origin. https://en.wikipedia.org/wiki/Telefunken
How did you find out hey are from that company? That's pretty nice.

It seems like the former owner had some ties to production.


Are we looking at CPUs here?
Do they have some collector's value?

TFK = Telefunken

[CPUShack]

Most likely not a CPU, these show up at many IC brokers stock lists so arent particularly rare

Probably used in some communication equip (as TFK did a lot with that sort of stuff)

Can I assume that they just have scrap value then?
(What would be the price per kilo? They seem to contain quite some gold)

[CPUShack]

$250-$300/kg on those usually

Very nice work

[Timo D]

Thank for that information about scrap value. What do you mean with "very nice work"?

And do I understand it right that these chips can basically just be scrapped because they have no collector's value?

[CPUShack]

very nice work in reference to alexander figuring out what it was
