Doug, I hope you don't mean you need to replace the chips with broken pins. This happened to a ROM in my oldest PET when I was trying to reseat it (poor contacts in sockets - I eventually replaced them with decent sockets). I stuck a thin piece of metal - a staple, as I recall - into the socket where the pin was supposed to go, and soldered it to the stub of the pin. Worked a treat! Philip.
