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.
