The punched card used in the IBM System/3 contains
In the late 1960s, IBM introduced a new, smaller, round-hole, 96-column card format along with the IBM System/3 computer. These cards have tiny (1 mm), circular holes, smaller than those in paper tape. Data is stored in 6-bit BCD, with three rows of 32 characters each, or 8-bit EBCDIC.
