Sharp EL-8
Brief History
Under a contract, Sharp aquired its first large-scale integrated (LSI) circuits from Rockwell, USA, from which in 1970 it was able to build the first extremely small calculator with LSI chips, the QT-8D. In 1971, a palm-sized version was completed. The EL-8 became a real hit at industrial fairs at the time. To today’s eyes, its unusual keyboard and forms of displayed numerals make it stand out.
Development has not stopped here, in fact, it has accelerated so much that in the second half of 1971, multiple companies mass-produced the first truly pocket-sized calculators, and the first one with memory (Sharp EL-8M) was released.
To conquer the European market, under an agreement between swedish Facit and Sharp, these models also appeared under their own brand name, with a slightly modified color scheme and shape.
