A modern Single-Board Olivetti M20 Clone, another Z8000 computer

A fellow enthusiast, Salvatore, sent me this cool M20 clone board to build so I can have my own Olivetti M20 compatible computer. Lately I’ve been having fun with the Zilog Z8000, a rather obscure microprocessor from the 80s. For a while I’ve been looking for a commercial Z8000 computer such as the Olivetti M20. They’re really hard to find, but perhaps it’s even more fun to build one from scratch! You’ll see me assemble a pre-release version of Salvatore’s pcboard, go through the various components on the board, and then boot Olivetti PCOS . For more vintage computer projects, see
