I have been salvaging old computers now for over 6 years and have kept all the CPU chips that I have found in them. Most of the chips being from 386, 486, and Pentium I computers. Is there a list anywhere that identifies which of these chips might be rare or hard to find? Before I scrap them for the gold content, I'd like to find out if any of them might be worth keeping or selling to someone interested in a particular chip. Thanks for any information you can give me.
