This is like a musical comedy. I'm thinking CHICAGO. Any minute now, I
expect Katherine Harris to go into Roxie Hart mode and sing: "It's just a
voting hall where's there's a nightly brawl and all...those...chaaaaads!"
June 1960, GLOSSARY OF TERMS IN COMPUTERS AND DATA PROCESSING (Berkeley
Enterprises, Inc., Newtonville, Mass.) by Edmund C. Berkeley and Linda L.
Lovett. Pg. 16:
chad--A small piece of paper tape or punch card removed when punching a hole
to represent information.
chadless--Paper Tape. A type of punching of paper tape in which each chad is
left fastened by about a quarter of the circumference of the hole, at the
leading edge. This mode of punching is useful where (1) it is undesirable to
destroy information written or printed on the punched tape or (2) it is
undesirable to produce chads. Chadless punched paper tape must be sensed by
mechanical fingers, for the presence of chad in the tape would interfere with
reliable electrical or photoelectric reading of the paper tape.
1960--GLOSSARY OF TERMS USED IN AUTOMATIC DATA PROCESSING (Business
Publications ltd., London), edited by Erroll de Burgh Wilmot. Pg. 10, col. 2:

CHADLESS TAPE: n. Paper tape in which a code is punched without perforating
completely, hence without making CHADS (_q.v._).
