The Model 2201 Programmatic Flexowriter described here was built after the Singer purchase, so it represents a mature machine, far more streamlined in styling than the machines of the 1950s. In January 1966 a substantial price reduction was announced in Britain ("of over 20%"), to £690 for the EC-130 and £810 for the EC-132 (nearly the average annual wage at that time). Friden (the calculator company) purchased CCC in the 1950s and was, in turn, purchased by Singer in 1965.

During the late 1960s and early 1970s, the company manufactured a number of electronic calculators, some marked with the Friden name, some marked with the Singer name and Friden included in the model number, and some marked with only the Singer name with no reference to Friden. The EC-132 model was introduced in 1965 and additionally has the square-root function. The Friden company was a well-established American manufacturer of electromechanical calculators when it was bought by the Singer company. The Friden EC-130, introduced in 1964, is a contender (together with the IME 84 and the Sharp CS10A) for the accolade of the first all-transistorised desktop calculator.
