The Elektronika B3-11 ranks among the simplest of calculators, its repertoire consisting of the basic arithmetic operations and semi-automatic exponentiation (whole positive exponents only). Its user-friendly features won it a gold medal at the VDNKh exhibition in 1974.
While the calculator is technically eight-digit, the results are shown on a nine-digit vacuum fluorescent display. The ninth digit is reserved for negative and overflow signs.
Numbers are shown in a decimal format with a natural point, fixed by the first number throughout the calculation process, until the “C” key is pressed.
The calculator’s stand lets the user change the angle for a better viewing experience and more effective cooling.
The calculator is powered by a 220V mains supply, with a power intake of 10 W or less.
