Pier Giorgio Perotto designs the Programma 101 (P101) for Olivetti, presented at the New York World's Fair in October 1964 and sold from 1965 for $3,200. It is the first programmable desktop computer with internal memory, magnetic-card storage, and the ability to print results, conceived for individual, non-technical use — the functional definition of the personal computer. NASA acquired 10 units for the Apollo program. IBM presented the IBM 5100 in 1975; the Apple II in 1977. The P101 precedes them by more than a decade. Hewlett-Packard paid Olivetti an out-of-court settlement over similarities with its HP 9100A (1968). The Anglophone canonical narrative of the PC rarely mentions the P101.
