<hardware> (IBM called this a "chip box") A metal box about
the size of a lunchbox (or in some models a large
wastebasket), for collecting the chad that accumulated in
Iron Age card punches. You had to open the covers of the
card punch periodically and empty the chad box.
The bit bucket was notionally the equivalent device in the
CPU enclosure, which was typically across the room in
another great grey-and-blue box.
