Introduced in 1949, the “026” became the standard workhorse of the punched card office for over 15 years. The cards were automatically moved from an input hopper, past the punching station, to an output hopper. As the holes for each column were punched for use by the machines, they were interpreted for people by printing on the top of the card.
