'''МК-61''' and '''МК-52''' are the most famous and popular Russian programmable calculators. They are the logical culmination of a series of programmable calculators, started by the Б3-34.

Program memory of the calculator is 105 teams (bytes). They have 15 registers and stack memory of the four basic registers (X, Y, Z, T), and one additional (X1).

Program memory of the calculator is 105 teams (bytes). They have 15 registers and stack memory of the four basic registers (X, Y, Z, T), and one additional (X1, to recover the result of a previous operation).

Unlike the МК-52 from the МК-61 is available at the first additional expansion memory module (512 bytes) and connectivity with expanded memory unit sewn in them programs.

This calculator uses the bracket-free (inverse) notation and stack programming language, which contains about 75 statements. This is an extension and continuation of a series of languages Б3-21, Б3-34, for which the backward compatibility. Attempted creation and further development of this family of languages (МК-161 and -152), but by the Soviet calculators is a mediocre relationship. The flowering of the national interest in this class of machines was in the late 70's - 80's of the last century.

Many of undocumented features of these machines once attracted many enthusiasts to investigation of it. In addition to practical purposes, programming has become a kind of exercise in skill and craftsmanship of Russian programmers.
