Description
This wallet-sized card shows punched cards on both sides. One is a ninety-column card with round holes, the other an eighty-column card with rectangular holes. The image of the ninety-column card has text along the left side that reads: Printed in U. S. A. REMINGTON RAND. The image of the eighty-column card has text along the left side that reads: Printed in U. S. A. REMINGTON RAND U-2173.
Remington Rand tabulating machines had used ninety-column punched cards. By 1959, Remington Rand computers could use either ninety-column punched cards, punched with round holes, or eighty-column cards, punched with rectangular holes. The latter form of card had been introduced by IBM. This small card shows the choices.
