Info: Info from the CASIO Website:
The relay-type computer AL1 was a scientific calculator with a programming function.
By setting a program using six gears, each with 60 teeth, a series of calculations could be performed automatically.
In addition, because the six gear units could be removed, multiple calculation routines could be programmed.
Due to this ease of use, the AL1 was popular among many government and university researchers.
One reason CASIO was able to develop such a useful calculator was the precise feedback it received from researchers during development.
These exchanges started with the development of the 14B, a technical relay-type calculator released in 1959 that featured a square root calculation function.
At that time, there were no programmable calculators for advanced technical calculations, and researchers spent a lot of time on computation rather than their primary work.
In 2014, the AL1 was recognized as an important achievement in the history of Japanese science and technology
and was listed on the register of essential historical materials for science and technology (future heritage technology) by the National Museum of Nature and Science in Tokyo.
