Shooting defective equipment is a wunnerful thing. ESPECIALLY the intermittent stuff that kept you guessing for a couple hours/days/weeks.
We used to routinely collect the stuff out of the service department and blast it into lil' chunks. Printer ribbons, tape carts, and hard drives are especially thrilling in the way they come apart....
It's a good ting, I'd recommend it to anyone.......
FWIW
