Amazing how you can have spare parts sit in draws for 25 years untouched. I'm a fan of AMD so I was excited to find two of these are from them. I'm wishing I had a better microscope to de-cap and view the die. I'll have to figure out how to see if Evil Monkeyz Designz is interested in any of these for a de-capping.
