Abstract
IBM's Supplies Division introduced the Port-A-Punch in 1958 as a fast accurate means of manually punching holes in specially scored IBM punched cards. Designed to fit in the pocket, Port-A-Punch made it possible to create punched card documents anywhere. The product was intended for "on-the-spot" recording operations -- such as physical inventories, job tickets and statistical surveys -- because it eliminated the need for preliminary writing or typing of source documents.
