=
lace card n. obs.
A punched card with all
holes punched (also called a `whoopee card' or `ventilator
card'). Card readers tended to jam when they got to one of these,
as the resulting card had too little structural strength to avoid
buckling inside the mechanism. Card punches could also jam trying
to produce these things owing to power-supply problems. When some
practical joker fed a lace card through the reader, you needed to
clear the jam with a `card knife' -- which you used on the joker
first.
