Welcome to Boardsort™ - Learn - Sell - Profit -

HI,
I have this boards about 100lb of them
Need help in grading them
Thank you

And this boards that came from cell tower amps.

all of those are specialty boards... send Chris an email and see what he has to say.

Can you guide me to where I can find his email?
Thank you

Thost top boards are ic blanks. Im not sure how boardsort will handle them but that's almost certainly an item for ebay (or a museum donation for a hell of a writeoff).
4 is amd atholon (k5 or k6 class)
I'm guessing on the rest but 3 looks like Pentium pro or original core blanks.
1/2 look like opteron from amd or xenon from Intel.

There's a fairly active computer collector's market that loves these unfinished CPUs and I've never seen a full punch sheet before.

The cellular receiver boards I've had them go from telco to cell class.
Before sending them to boardsort...
Gently, very gently, put the board over the edge of the counter or table about half way. Hold the side ON the table with good force and gently push down on on the side hanging off the table.
You want to know if it's a standard polymer board or a metal sandwich. If it gives, ever so slightly boardsort is good.
Uf there is absolutely no play it may be a metal sandwich board, most commonly a sheet of punched titanium.
If it's a metal board you're probably better off with a large local yard who can account for not just the board's pm value but the internal skeletal material as well. Nickel is in the $3 range per pound right now where titanium is $9.50-$12 depending on alloy.
Good luck and great find

Thank you for all the info.
Pentium Pro like in the Pentium Pro the King of all cpu's for recovery?
That could be amazing, there are 240 cards on each sheet.

I have posted on one of the vintage computer forum, I will donate one if there is a museum that would like to display them.

I will email chris soon.

what is the substrate the material is on for those sheets? I'm having a really hard time seeing how those would be IC chip blanks... from the pics, it looks like its on a plastic type material. The bottom ones look like they could be contact points for a cartridge of some sort. Do you have an idea what the base material is?

Regardless of what they are, I think you definitely have something of collector value... Ebay would probably be the best route to go, but it never hurts to check with Chris.

Let me be a little more clear. Those are the top layer of the CPU (or bottom most)
Blank in that's a machine fed "sheet", not a finished product.
there's no doubt those first sheets, #4 are atholon.I've done enough with that generation to recognize the cmc and cap layout instantly.

The late k5 and early k6 double wide server class cpus. I used to pull the caps off Dead ones for refining.
