The Electronika MK- 85 is a Soviet programmable calculator (microcomputer) with the built-in BASIC interpreter. Produced by the Angstrom factory in Zelenograd from 1986 to 2000. The microcomputer was designed for scientific, engineering and statistical calculations. The computer performs all operations with a maximum error of ± 1 in the tenth of digit number. It automatically runs a previously recorded program, four arithmetic operations, calculate direct and inverse trigonometric functions, decimal and natural logarithms, exponential functions, square root, absolute value, the definition of the sign, the integer and fractional part of the number and the generation of random numbers. Presumably, in 1986 the MK-85 was the only one calculator equipped with 16-bit microprocessor.
