punched card machine that could multiply, the 600 Multiplying Punch. Their first alphabetical accounting machine - although not a complete alphabet, the Alphabetic Tabulator Model B was quickly followed by the full alphabet ATC. 1931: The term "Super Computing Machine" is used by the New York World newspaper to describe the Columbia Difference Tabulator, a one-of-a-kind special purpose tabulator-based machine made for the Columbia Statistical Bureau, a machine so massive it was nicknamed "Packard".

By 1937 IBM had 32 presses at work in Endicott, N.Y., printing, cutting and stacking five to 10 million punched cards every day. 1938: Powers-Samas multiplying punch introduced. 1941 Introduction of Bull Type A unit record machines based on 80 column card. 1943: "IBM had about 10,000 tabulators on rental [...] 601 multipliers numbered about 2000 [...] keypunch[es] 24,500". 1946: The first IBM punched card machine that could divide, the IBM 602, was introduced. Unreliable, it "was upgraded to the 602-A (a '602 that worked') [...] by 1948". The IBM 603 Electronic Multiplier was introduced, "the first electronic calculator ever placed into production.". 1948: The IBM 604 Electronic Punch. "No other calculator of comparable size or cost could match its capability". 1949: The IBM 024 Card Punch, 026 Printing Card Punch, 082 Sorter, 403 Accounting machine, 407 Accounting machine, and Card Programmed Calculator (CPC) introduced. 1952: Bull Gamma 3 introduced. An electronic calculator with delay-line memory, programmed by a connection panel, that was connected to a tabulator or card reader-punch.
