MIR (Russian:МИР) is a series of early Soviet transistorized minicomputers. It was developed from 1965 (MIR), 1968 (MIR-1) to 1969 (MIR-2). The development team was led by Victor Glushkov.

Overview

MIR (МИР) stands for «Машина для Инженерных Расчётов» (Machine for Engineering Calculations) and means both "world" and "peace" in Russian. It was designed as a relatively small-scale computer for use in engineering and scientific applications. Among other innovations, it contained a hardware implementation of a high-level programming language capable of symbolic manipulations with fractions, polynomials, derivatives and integrals. Another innovative feature for that time was the user interface combining a keyboard with a monitor and light pen used for correcting texts and drawing on screen.
