Removed from an old computer system.

Each board weighs 106grams (approximately) and look identical to eachother.

Not sure what the use of these was but have been told that they may contain traces of precious metals i.e gold or other.

They have not been tested so unable to confirm if they still work (but by looking at them they don't look worn or burnt out).

There is a company name printed on them 'Test Research Inc' 8001-100-2 and various other detail which reads Plotech 4 94V-0 0554-4225 which may be a model number or serial number. All the boards have these identifying numbers. I have googled them and nothing shows up.

Selling as a job lot of 10, but I do have more if you would like them all!.
Also selling as 1 on its own if you wanted to purchase one to see if it is what you require. (price is just to cover our costs to send!).

Please understand, I do not wish to mislead anyone. I do not know what these were used for or if they contain any materials which are salvageable.

PLEASE ALSO NOTE THAT SOME OF THESE MAY HAVE SLIGHT DIFFERENT PATTERNS ON THEM. I WILL DO MY BEST TO SUPPLY AS IN PICTURE BUT SOME MAY COME THROUGH WITH DIFFERENT PATTERNS ON.

Any questions please ask!
