Olivetti Programma 101

The Olivetti Programma 101 is a programmable calculator with 10 digits precision and algebraic logic. It has 6 functions, 36 keys, and a printer. The power source is Mains. Widely regarded as the first programmable desktop calculator, and for many years the market leader, this machine uses discrete transistor logic and delay-line memory. It was eventually displaced by the Hewlett Packard 9100A calculator. Hewlett Packard eventually had to pay royalties to Olivetti for infringing various patents related to the P101 design. Note: Also known as Olivetti P101.
