Nairi-3 and Nairi-3-1, which used integrated hybrid chips, were developed in 1970. These computers were used for a wide class of tasks in a variety of areas, including

A modification "Nairi-2E" was also produced, specialized for the automation of experiments. It contained in its kit a magnetic tape drive NML-67 and an interface unit with measuring equipment.

Through the advances in computer technology since the initial production year of 1964, it became possible for upwards of 128 thousand

A series of computers for special applications. Nairi 4 ARM / Nairi 4 and Nairi 41 were developed in 1974-1981. Their development started by
Hrachya Ye. Hovsepyan. Lastly their chief designer is German Artashesovich Oganyan. The system was software-compatible with the

Since 1964, the machine has been produced at two factories in
Armenia, as well as at the Kazan computer plant (from 1964 to 1970, about 500 machines were produced in total). In the spring of 1965, the computer was presented at a fair in

The processing power of the Nairi-3 was considerably higher than competing systems due to multiple storage system improvements. Some of which includes the usage of a long-term form of

The development of the machine began in 1962, completed in 1964. The chief designer is
Hrachya Yesaevich Hovsepyan, the leading design engineer is Mikhail Artavazdovich Khachatryan.
