Olivetti Logos 9 Printing Calculator was released in 1981. It was designed by Mario Bellini - world-renowned Italian designer and architect, who also had a hand in designing other Olivetti products.

Olivetti's first LCD model; it was the world's smallest printing calculator at 4.5" x 2.5" x 1" (6.2 x 11.8 x 2.5 cm). In addition to the basic four functions, it calculates averages, totals, percentages, and displays the time. The printing mechanism disappears from view when the display section is closed up against the keypad section. A sleek, sparse, professional-looking unit, this model is a great example of minimalist design.
