... chip puller tools...
... I use a tiny screwdriver and slowly pry around the processor until it pops out.
When I was ready to restore the LC back to the 631, I got in a hurry and bent the pins. Some of the pins may bend at the middle of the pin, rather than at the point where it meets the processor package. If this happens, it's hard to straighten them out.
Butter knife, again: multiple bent pins can be straightened by inserting an object - substantially as wide as the gap - between rows of pins, then twisting that object along its long axis, using the base of the adjacent row of pins as the fulcrum. This trick works vertically, horizontally, and diagonally on the face of the pin-side of the chip. Assess your progress by sighting edgewise over the chip along any row of pins - up, down, or diagonally - to ensure that all in that row are as neat as fence-posts.
For middle-bent pins you may have to go at individual pins with a pair of surgical tweezers or a hemostat (which is a very useful tool to have, btw, so grab one if you see one - or talk to your dentist).
As for chip removal, I recommend a gentle twisting action along the shaft of a good-quality, small, flat-bladed screwdriver - such as you'd find in a jeweller's set - and lots of iterations of insert-twist-withdraw-sideslip-insert...
