The HP-35 calculator, first introduced by the Hewlett-Packard Corporation in 1972, provided the four functions of arithmetic, as well as the transcendental functions of trigonometry and logarithms, to an accuracy of over 10 decimal digits, with a two-digit exponent of ten for numbers expressed in scientific notation. It was designed to fit in a shirt pocket.
This specimen was transferred to the Museum from the NASA Ames Research Center in 1985. It was not flown in space. Similar HP-35 calculators, however, were used in the Skylab missions, replacing the slide rules carried on previous Apollo spacecraft.
