Elea 9003

The Elea 9003 is one of a series of mainframe computers Olivetti developed starting in the late 1950s. 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 announced only a few months after the release of Siemens 2002 and several months before the first IBM transistorized computer.
