Olivetti M21 - The Portable version of Olivetti M24

In late 1983 Olivetti released their first Portable PC - the Olivetti M21. Join me on this quest to bring this 40-year, and very rusty, computer back to life. Bios version 1.1 has been uploaded to my account: @tibo_retro_computers The 3D model of the keyboard lock can also be found on my account! #Olivetti #Portable #M21
