What was the original name of the Texas Instruments calculator?
1965 — Texas Instruments (USA) begins work on a hand-held calculator, code named “Cal-Tech.” It was to be developed as a prototype to show the potential of TI’s recently-developed integrated circuits (which were not selling as well as they had hoped).
How much did the first pocket calculator cost?
The device featured user-definable keys (with 35 keys controlling more than 80 operations) and was the first HP pocket calculator with base conversions (octal and decimal). The calculator cost $795 when it launched in 1974. In 1975, during the first joint U.S.-Soviet space flight, it became the first handheld calculator in outer space.
