The Olivetti M20 is a Zilog Z8000 based computer designed and released by Olivetti in 1982. Although it offered good performance, it suffered from a lack of software due to its use of the Z8000 processor and custom operating system, PCOS. The company introduced the IBM PC compatible Olivetti M24 in 1983 and the M20 line was phased out.
