The IBM 603 Electronic Multiplier was the first mass-produced commercial electronic calculating device; it used full-size vacuum tubes to perform multiplication and addition. (The earlier IBM 600 and released in the same year IBM 602 used relay logic.) The IBM 603 was adapted as the arithmetic unit in the IBM Selective Sequence Electronic Calculator. It was designed by James W. Bryce, and included circuits patented by A. Halsey Dickenson in 1937.The IBM 603 was developed in Endicott, New York, and announced on September 27, 1946.

| - La IBM 603 Electronic Multiplier (Multiplicador Electrónico) fue el primer dispositivo calculador electrónico comercial producido masivamente, utilizando 300 tubos de vacío en una gran cajapara efectuar operaciones de suma, resta y multiplicación (los anteriores de la serie 600 eran electro-mecánicos, salvo la variante no comercial Aberdeen Relay Calculator del IBM 601 que implementaba su lógica con relés). La IBM 603 fue adaptada como la unidad de aritmética del ordenador electromecánico de IBM Selective Sequence Electronic Calculator (Calculador Electrónico Secuencial Selectivo). (es)

Fue diseñado por , e incluía circuitos patentados por A. Halsey Dickenson en 1937. El IBM 603 fue desarrollado en la sede de Endicott, Nueva York, y se anunció el 27 de septiembre de 1946. Sólo fueron construidas unas 100 unidades, los voluminosos tubos de vacío que empleaba la hicieron complicada de fabricar, pero la demanda demostró que el producto llenaba una necesidad. Se demostró que la máquina era capaz de dividir, pero el resultado solo podía usar 3 dígitos de precisión por falta de más tubos. El IBM 603 fue el predecesor del IBM 604 con 1.100 tubos, era un dispositivo programable con capacidades más complejas y que ya podía dividir, utilizando un diseño patentado de módulos enchufables que hacían al producto más fácil de fabricar y mantener.

Only about 20 were built since the bulky tubes made it hard to manufacture, but the demand showed that the product was filling a need. The commercial interest in the 603 came as a surprise to IBM and Thomas Watson Sr, head of IBM, felt that the device had limitations so Ralph Palmer and Jerrier Haddad were hired to develop a more refined and versatile device, the IBM 604 Electronic Calculating Punch. The IBM 603 was the predecessor of the IBM 604, a programmable device with more complex capabilities. The 604 used miniature tubes and a patented design for pluggable modules, which made the product easier to manufacture and service. Throughout the following 10 years IBM would build and lease 5600 of the IBM 604. (en)
