Welcome in the Olivetti M20 site
This site is intended to be a meeting point for the M20 community and a collection of informations and manuals dedicated to this computer.
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. Among its peculiarities there was the choice of the CPU, the Zilog Z8001, and the operating system, called PCOS, which was developed by Olivetti especially 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 attempt to preserve as much as possible the technical informations and the software which was developed for this machine.
