I've run into really horribly mutilated ICs that kept working. When I was
at Berkeley they had a display with a little 555-based oscillator driving an
LED in Cory Hall (engineering). The 555 had a pit blown in the epoxy and you
could see the silicon at the bottom of the pit. Looked just like a car window
that had been plinked by a rock. Still worked just fine.
