It is not worthless. Prices have changed. I think its worth is in the fact that it helps you identify what chip/version you may own. If price is a huge consideration you can always post the I.D. # and someone can give you the TCR 10 value or pay the $50 for TCR 10.

I am not asking big bucks for this - I wanted to trade some chips to cover S&H. Let me know. Thanks.
