   chad box
   chip box
      <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.
