IBM 608 The IBM 608 Transistor Calculator, a plugboard-programmable unit, was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the world's first all-transistorized calculator to be manufactured for the commercial market. The 608 contained more than 3,000 germanium transistors. Announced in April 1955, it was released in December 1957. It was similar in nature of operation to the vacuum tube IBM 604, which had been introduced a decade earlier. Although the 608 outpaced its immediate predecessor, the IBM 607 by a factor of 2.5, it was soon rendered obsolete by newer IBM products and only a few dozen were ever delivered. The 608 was withdrawn from marketing in April 1959.
