Chad Box
/chad bäks/
n. Iron Age card punches contained boxes inside them,
about the size of a lunchbox (or in some models a large
wastebasket), that held the chad (sense 2). 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
gray-and-blue box.
