  1. Airborne Argon-17 computer system.
  2. Chief designer: V. G. Cherkesov.

    Development engineers: M. S. Borisov, V. I. Alekseev, A. F. Bogachyov, N. M. Kurakhtanov, A. Ya. Tyurin, A. I. Feldsherov, V. V. Churilin, N. M. Shchit, B. I. Yurgaev.

  3. Designing organization: Research Institute of Computer Engineering (NICEVT) of the USSR Ministry of Radio Engineering (since 1986 - Research Institute NII Argon).
  4. Manufacturer: 50 Years of the USSR Computer Factory, Kishinyov.
  5. Completion of development: 1976.
  6. Beginning of production: 1978.
  7. Termination of production: 1991.
  8. Field of application: inertial guidance system of an antiballistic missile.
  9. Description: three-channel synchronous redundant computer system. A bit-by-bit majorization of data and control buses is implemented and redundancy of interface elements is provided in data exchange. Such a structure ensures safe operation even when failures occur in unlike bus bits and different channel circuits connected with them.

    The computer is based on the proprietary POISK architecture developed at NII Argon. It allows adapting an instruction set to control system functions. The machine consists of a three-channel computing and data exchange unit, RAM, an instruction ROM, a firmware ROM and a power supply unit.

    Representation of numbers - fixed point; data types - bit, byte, word (16 bits), double word (32 bits).

    Instruction set - general-purpose statements, special statements, and standard procedure statements.

    Number of instructions - 132. Addition speed - 2 ms.

    RAM capacity - 4 Kbytes, instruction ROM capacity - 32 Kbytes, firmware ROM capacity - 24 Kbytes.

    Number of exchange buses - 8.

    Data rate - up to 160 Kbps.

  10. Element base: 583 family microprocessor LSIs, 106, 134, 530 and 533 family ICs.
  11. Design: the computer contains a three-channel computing and exchange unit, three RAM modules, three instruction ROM modules, three firmware ROM modules and three power supply units integrated in a common case. All of them are connected by special cables with connectors.

    The printed circuit boards of all units except power supplies are assembled in a book-like package and interconnected by a special rubber "spine" with flexible wires.

  12. Technology: unified multilayer printed circuit boards made by pairwise pressing. ICs are surface-mounted.
  13. Software: a standard program set; special subroutines, automated YaSKO programming system, a set of tests.
  14. Specifications:

    Volume - 70 qdm.

    Weight - 30 kg.

    Power consumption - 100 W.

  15. Special features: high reliability due to tripled synchronous structure with hardware majorization. Special technical means are used to ensure the machine functioning since the trigger moment. High radiation resistance ensures the task fulfilment in case of nuclear explosion.
