Personal computer, 1982, Olivetti. The M20 was designed at Olivetti's Advanced Technology Center in Cupertino and presented in 1982 as the company's first 16-bit personal computer. It is built around the Zilog Z8001, a powerful but rarely used processor, with its own operating system PCOS and a bitmapped 512 x 256 display; the choice made it incompatible with the IBM PC and it was replaced two years later by the M24, although an 8086 add-on board (the APB) later allowed it to run MS-DOS. The system unit, keyboard and monitor were designed by Ettore Sottsass. The M20 ST is the standard configuration, aimed at scientific and technical use.
