The IBM 407 Accounting Machine, introduced in 1949, was one of a long line of IBM tabulating machines dating back to the days of Herman Hollerith. It had a card reader and printer; a summary punch could be attached. Processing was directed by a control panel.
The 407 was the central component of many unit record equipment shops which were the mainstay of IBM's business at the time. It could print digits, letters and several special characters in any of 120 print positions, spaced 0.1 inches apart (2.5 mm).
IBM stopped marketing the 407 Accounting Machine in 1976.[1]
