Welcome in the Olivetti M20 site

M20 at work The Olivetti M20 was a personal computer dedicated to business and scientific areas. It was produced by the Italian company Olivetti between 1982 and 1985 and distributed in many countries. Among its quirks, there was the choice of the CPU, the Zilog Z8001, and the operating system, called PCOS, which was especially developed by Olivetti for this machine.

Olivetti has always been extremely attentive to the design of its products; the M20 was not an exception and it was drawn by the pen of Ettore Sottsass.

We want to preserve as much as possible the technical information and the software which was developed for this machine.
