Overview

The speed of the MIR-2 machine is about 12,000 operations per second. The capacity of the random access memory (12-μs circulation cycle) is 8,000 13-bit symbols. The read-only memory has a capacity of about 1.6 million bits with a cycle of 4 μs, which is enough to store several tens of thousands of micro-commands. There is a buffer memory for output information with a volume of 4000 10-bit words. As external devices were used: input from punched tape, output to punched tape, electric typewriter Soemtron, magnetic card drive, vector graphic display with light pen.

As the input language in the MIR-2 machine, a special high-level language Analitik was used, which developed the concepts of the MIR-1 built-in programming language and additionally allowed the formulation of tasks with analytic transformations of formulas, allowing analytical expressions for derivatives and integrals.
