The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add, multiply, subtract, and divide, and its output device was a paper tape.
The HP-67 is a magnetic card-programmable handheld calculator, introduced by Hewlett-Packard in 1976 at an MSRP of $450. [1] A desktop version with built-in thermal printer was sold as the HP-97 at a price of $750. [2]
Jack Kilby went on to pioneer military, industrial, and commercial applications of microchip technology. He headed teams that created the first military system and the first computer incorporating integrated circuits. He invented the handheld calculator (along with Jerry Merryman and James Van Tassel [6]).
Was the first scientific calculator to fly in space in 1973. [5] HP-35 calculators were carried on the Skylab 3 and Skylab 4 flights, between July 1973 and February 1974. [6] Is the first pocket calculator with a numeric range that covered 200 decades (more precise 199, ±10 ±99). [5]
