Found a collection of old ceramic CPU’s. Exposing the dies

I have a ton of crap I have collected over the years and I come across a bag of old CPU chips – early pentiums, some DEC alphas and some SUN ultrasparc chips that I had kept for some reason. There’s even the main VLSI chip from a Wang 2200 2nd generation system my dad’s work were still using until the late 1990’s. Seem as they are so old now I thought I’d crack them open and expose the dies to see what’s inside of them. Here’s some photos of them. Click on the photo for a description of what they are and where they came from.
