The IBM 1401 was a variable wordlength decimal computer that was announced by IBM on October 5, 1959. The first member of the highly successful IBM 1400 series, it was aimed at replacing electromechanical unit record equipment for processing data stored on punched cards. Over 10,000 units were produced and many were leased or resold in less developed countries after they were replaced with newer technology. The 1401 was withdrawn on February 8, 1971.
