I'm in for a C1702 Smile

The C1702A isnt THAT worthless... it still has gold value, remember? Laughing

PPRO's have about $3-4 in gold value, or more (do you ever watch those goldscrap auctions on ebay? because gold is at $600+ an ounce, their value goes up just the same). The small, older gold chips like the C1702A have a very high gold content because earlier in the chipmaking days they used lots of gold to carry signals inside the core. As time went on, they slowly transfer(Notice I didn't say transferred- they still use gold on CPU's today because believe it or not, it's the cheapest way to do it. Some alloys would cost Intel or AMD a bundle to produce) to other metals and alloys.
486's have the highest gold content, and I'm pretty sure the P60's are next in line.
With 8-9lbs of 486's, you can make one ounce of 24kt pure gold.
