General Instrument
General Instrument Corp.
Horsham, PA, USA

General Instrument was a diversified company which manufactured calculators in Canada in the mid-1970s, and its General Instrument Microelectronics division was a pioneer in MOS (Metal-Oxide Semiconductor) technology and was one of the leading manufacturers of calculator integrated circuits. Like Texas Instruments and Rockwell, General Instrument decided that there was a profit to be made in manufacturing the finished calculators as well as the integrated circuits.

It produced a range of distinctively styled LED display calculators in the mid-1970s, but after a couple of years, when the price of calculators plummetted, together with the profits, it appears to have sold the designs to the U.S.S.R. (Russia). Similar designs appearing under the Elektronika and Elorg names were produced for a number of years under the command economy of the U.S.S.R., when such designs were long obsolete elsewhere.
