Olivetti Programma 101

         Olivetti Programma 101

         Programma 101 comes introduced in 1965 during the BEMA elecronic
         show,in New York.It represents the first "desktop calculator" ever
         constructed in the world.
         40.000 exemplary were constructed at the price of 3.200 $
         The machine offered the possibility to carry out arithmetical
operations in direct way, or of being programmed for the
calculation of complex functions.
         The programs could be stored in magnetic stripes.
         It was entirely planned and realized in the Olivetti research
laboratories of
         Pregnana, from a group of researchers guided from the Ing. Piergiorgio
         Perotto, the design was from the Arch. Mario Bellini.
