UM1-HX is an electronic computer for solving control and management tasks. It was created in KB-2, in Leningrad , under the leadership of F. G. Staros and I. V. Berg . Development has been carried out since 1958, in 1962 the machine was adopted by the State Commission, since 1963 it was produced in series at the Leningrad Electromechanical Plant [1] . For the development of the machine in 1969, the developers were awarded the USSR State Prize in the field of science and technology.
The first Soviet mini-computer .

Specifications
Cell computer database - discrete transistors , about 8000 pieces, resistors and capacitors . The logical base is resistor-transistor . RAM - on ferrite plates. Dimensions of the main unit - 880 × 535 × 330 mm, power consumption - 200 watts.
The machine used a binary system, the operations performed on fixed-point numbers. Command system - mixed addressing, one-, two- and three-address commands, with developed I / O operators, designed for use in real-time systems.
- Bit depth - 15 binary digits (14 + 1 signed).
- Bit teams - 20 binary digits.
- Performance - 5000 additions, 1000 multiplications or divisions per second.
- RAM:
- internal: numbers - 256 words, constants - 512 words, commands - 2048 words.
- external (as part of a cabinet with peripheral equipment, optional): numbers - 512-4096 words, commands - 512-4096 words.
The input-output system included, in addition to an apparatus for reading and writing punched tape and a console with an electric typewriter, a set of ADCs and DACs , as well as serial digital channels. The maximum number of channels served is 2048 per input and output.
Command System
It has a total of 32 teams.
The command system includes special operations that ensure the exchange of information between the machine and control objects, as well as real-time operation .
Internal I / O
The control machine had 8 channels for entering information in the form of a DC voltage from −5 to +5 V and 8 channels for entering information in the form of a shaft rotation angle.
Dimensions
Dimensions of the machine UM-1NX - 880 × 535 × 330 mm, weight without power supply - 80 kg.
Power consumption of 200 watts.
Use
UM1-NKh was used to control technological processes at the Chromatron color picture tubes factory , [2] to control the Votkinsk hydroelectric station . [3]
- 1150 blooming pressure control system at the Cherepovets Metallurgical Plant . [4] [5]
- The control and regulation system of the 2nd unit of the Beloyarsk NPP , the central subsystem of which consisted of two UM1-HX machines operating in the “hot” reserve mode. About 4 thousand I / O channels connected to 15 constructs of USO UM1-HX were connected to them. The complex was equipped with 120 angle-code converters. [four]
