Digital computer

Digital computer Robotron 4201 is mini-computer with 16-bit word architecture and 16K words memory. The operation rate of processor is 1,3 - 200 mcs. The computer includes interruption system, real-time clock and peripherals for loading perfotapes and interchange with DASIO. The instructions system of processor consists of only 53 machine instructions and does not include even floating point operations, so this computer is simpler than any modern cheap controller. But developers could place inside all main models and control logic of simulator.
