To take care of the ergonomics and aesthetics of a product that did not exist before, Roberto Olivetti called Mario Bellini , a young Italian architect: I remember that one day I received a call from Roberto Olivetti: "I want to see you for a complex project I'm building". It involved
520-416: A desktop computer, sort of, kind of, called an Olivetti Programma 101. It was a kind of supercalculator. It was probably a foot and a half square, and about maybe eight inches tall. It would add, subtract, multiply, and divide, but it would remember a sequence of these things, and it would record that sequence on a magnetic card, a magnetic strip that was about a foot long and two inches wide. So you could write
