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[edit]
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.
