Most of us have seen photos of a silicon chip die, usually magnified. In many of those chips, specially the large ones, the several logic areas are visible by naked eye. In this instructable I am showing you the steps to open-up an i486 DX2-66 CPU and inspect the contents! It's a rather large (and slow for these days :-) ) silicon chip. It's a very easy task, as soon as you are patient and gentle, because the contents are a bit fragile!
Step 1: What you will need
2) A hammer (not a very heavy one!)
3) A chisel with sharp edge
Step 2: Prepare for the job
Then, position the edge of the chisel exactly at the point where the metal cover meets the underneath of the ceramic CPU packaging. You have to maintain an angle smaller than 45 degrees, (smaller than shown in the photo), in order to avoid breaking the CPU packaging. You may have to bend the pins in order to position the chisel to a small angle.
