One of the first electronic calculators in the world, designed and manufactured as such. Considered sto be second only to the English Anita, which is actually a mechanical calculator filled with electronic elements. From historic point of view at the same time (early and mid-1964) Mathatron 4-24, SCM Marchant Cogito 240, IME 84 came on the market. In any case, Friden was one of the pioneers.

The company's owner, Carl Friden, produced mechanical calculators from the mid-1930s, which sold with great success until the early 1960s. He was clever enough to understand possibilities of electronics and began developing a fully electronic calculator in 1961. His creation was shown in mid 1963, but hit the market in mid 1964. A year later, in April 1965 - the same time as Bulgarian Elka 6521 - Frieden introduced next model 132 with a square root function.

The reason for being presented in the Museum of Bulgarian Electronics is the possibility to be compared to Elka 6521.
