In parallel with the release of the “Minsk-1” at the Plant, the development of the second generation of computers, “Minsk-2″, was undertaken.”Minsk-2” subsequently became the first semiconductor computer in the USSR.
The speed of the unit was estimated at 5-6 million operations per second. It is important to note that the “Minsk-2” became the first computer in the entire Soviet Union where text could be entered and processed. Before this, all the machines worked exclusively with computer code.
However, the serial production of the machine did not go ahead straight away. The USSR State Committee for Electronics, to which the technical design of the machine was sent for approval, refused to accept it. As far as the Committee was concerned, the SDB factory should only be engaged in the testing and improvement of already existing computers rather than being involved with developing new ones.
It was only after the intervention of senior management of the Belorussian USSR that the project was approved, and then in 1963 full-scale production began. In all, the plant issued 118 “Minsk-2” computers.
On the basis of the “Minsk-2”, a number of modified computers were also created. The “Minsk-26” and “Minsk-27” , for example, we intended for processing data received from meteorological rockets and satellites «Meteor».
The most popular model was the “Minsk-22” (in all, 734 units were released), which compared with the base model, had several times more RAM, and a tape drive.
