Soviet radio "Micro" 1965

    A couple of years ago I ended up in the local history museum of Moscow Zelenograd . Such a standard museum of local history of any small area: the history of the region, a separate stand dedicated to the Second World War (the Germans were stopped in the Battle of Moscow in those places), and a separate room dedicated to the microelectronic industry of the USSR and Russia.

    In Zelenograd, important enterprises of the microelectronic industry of Russia are located. Many of you are familiar with the products of the Angstrom plant, it was they who were involved in the release of the games of the series “Wolf Catches Eggs”. But my eyes were literally riveted by a small box smaller than a matchbox with a headphone coming out of it, reminiscent of modern earplugs. It was a miniature transistor radio "Micro" - the first serial product of microelectronics, launched into production in the USSR.

    The release of the receiver was dated 1965. It was then that Anatoly Korobov with the team received the copyright certificate for this device. They were assembled at the Angstrom plant, mass production was transferred to the Minsk Radio Plant. By the way, for Angstrom, this was the first experience in manufacturing a finished device for mass production. They were produced not only in the domestic market, but also for export.

    Until the mid-seventies, this micro receiver could be bought in stores in the USSR and France. This receiver made a worldwide sensation at the congress of radio engineers in the United States. They wrote about him in the newspapers: "How was the USSR able to overtake us?" It is noteworthy that even Khrushchev took them abroad as souvenirs, gave them to Gamal Nasser and even Queen Elizabeth herself.
