mainframe Olivetti Mario Tchou Italy Programma 101 mainframe computer
The Elea 9003 is one of a series of mainframe computers Olivetti developed starting in the late 1950s. The first prototype was created in 1957. The system, made entirely with transistors for high performance, was conceived, designed and developed by a small group of researchers led by Mario Tchou (1924–1961). It was the first solid-state computer designed (it was fully manufactured in Italy). The knowledge obtained was applied a few years later in the development of the successful Programma 101 electronic calculator.
