   Word length - 32 bits.

   Data representation - whole word, half-word, byte, bit.

   RAM capacity - 32 to 34 Kbytes.

   Command memory capacity - 64 to 256 Kbytes.

   I/O subsystem - independent I/O processor supporting information exchange through 12 channels with maximum speed over 1 Mbps.

   Number of modifications - 2.

10. Special features: the computer is easily adaptable to various performance and memory capacity requirements of control systems and capable of restoring computational process after hardware malfunction or failure. In has non-volatile memory which allows copying data from external recording devices. The machine's effective management system with dual-level fault cell localization ensures effective repair of the hardware by technicians.
11. Element base: standard series of TTL ICs.
