In practice, this definition would likely be used for punching a special symbol as a "continuation character" in column 72, and then columns 73-80 could either be punched with a card sequence number or the card could be released at that point, if no further typing was required. Note: "Field Definition" (12) and "Alphabetic Shift" (1) prints as an A. If program 2 codes were punched, invalid characters could be generated that the printer did not know how to print, some of which could even damage the printer. Program cards could automate certain tasks, such as "gang punching", the insertion of a constant field into each card of a deck of cards. For amusement, program cards could even be set up to play music by gang-punching "noisy" characters (characters represented by many holes, usually special characters) and "quiet" numbers and letters in rhythmic patterns. IBM 5496 Data Recorder for 96 column cards In 1969, IBM introduced the System/3 family of low-end business computers which featured a new, smaller-sized, 96 column punched card. The IBM 5496 Data Recorder, a keypunch with print and verify functions, and IBM 5486 Card Sorter were made for these 96-column cards. Powers, Remington Rand (UNIVAC) keypunches Beginning around 1906, an employee of the United States Census Bureau, James Powers, developed the Powers Keypunch, which was specific to the census application and had 240 keys. In 1911, Powers formed Powers Accounting Machine Company. That company was taken over by Remington Rand in 1927. Remington Rand's UNIVAC division made keypunches for their 90-column cards and similar machines for the IBM 80-column card. Their 90-column keypunches used a mechanical system developed by Remington Rand to avoid IBM patent issues (long before the acquisition of Eckert–Mauchly Computer Corporation). UNIVAC keypunches stored the sequence of characters for an entire card, then punched all its holes in a single pass, which allowed for corrections instead of wasting a card in case of error. Remington Rand keypunches included: UNIVAC Card Code Punch Type 306-5, 90 Column Alphabetical (Types 306-2, 306-3), 90 Column Numerical (Types 204-2, 204-3), Portable Electric Punch Type 202, Spot Punch Type 301, and the Automatic Verifying Machine Type 313. The Type 306-2 provided for verification; the cards were passed through the keypunch a second time and keyed again. The verify-punching of the same cards in the same sequence ... results in the elongation of perforations for correct information. Round perforations
