Meet one of the more complicated mechanical devices ever built by Man, the Olivetti 27-2
In this video I show the Olivetti Logos 27-2, a very complex calculator, and the Olivetti 27-1. These are calculators from 1960s. If you like old mechanisms and old technology, the Olivetti 27-2 is your calculator. Many thanks to Emanuele for the precious information and document he gave me on this calculator.
