Need some guidance on how to sort these. Thanks!

They are all nice! I see two G5s from a powermac, an Intel slot processor. A Sun Microsystems Ultrasparc II maybe III module.

A cisco systems Risc processor maybe.
I'm sorry I have no idea on sorting, I have about the same questions you do.
Mine thing good about your lot is that they have the gold plated Velcro type socket pins. well except the slot processor.

Also that Intel SATA raid controller bridge it has a nice chip, and gold fingers.

Myself, like you im sure am hoping that they are graded higher.. I hope someone with Boardsort knowledge chimes in.

First pic top row left to right: all of them are Green/Brown Fiber with Metal.

First pic bottom row left to right: Slot Processor, Peripheral (i guess), and Green/Brown Fiber with Metal.

Second pic top row left to right: *Slot Processor, Green/Brown Fiber with Metal, and Slot Processor.

Second pic bottom row left to right: Green/Brown Fiber with Metal, Green/Brown Fiber with Metal, and Gold Finger Card.

* This board you may get more by removing the cpu's with the gold tops. Take a closer picture of the cpu's and post them to try to get the proper grade and see if it is worth scraping the board. If you remove the cpu's you may still get Gold Finger Card grade*

Thank you. I only have 2 of the ones with the gold top processors, which are soldered. For me it's too much effort for the difference.

with the Sun Sparc boards, there is sometimes a part that is often overlooked... when you take the main CPU out of its holder there is a connector between the bottom of the CPU and the board... if that connector is a thin, somewhat translucent film, its not worth much of anything.

BUT, if it is thick black plastic square with gold looking wires in it, it is worth something to a refiner. It is called a fuzz-button interconnect (often made by Cinch) and they are worth hanging on to, so dont throw them away. The wire is a a gold/copper alloy that has a rather high gold yield.
