Olivetti MC-24

Machine-translated from the Italian article

The designation MC-24 denotes a series of electric, automatic calculating machines with integrated printing and a dynamic memory register, produced by the Italian company Olivetti starting in 1956. The mechanics were designed by Natale Capellaro, while the casing is due to Marcello Nizzoli. The most famous and best-selling model (over one million units were produced), the Divisumma 24, besides being a revolution in the automatic calculator sector, has also become an icon of Italian industrial design.
