Vintage Soviet calculators

Malatron sez, "72 different calculators from Soviet times. All are from collection of Sergei Frolov. Different in size, colour and functions but all from one brand 'Electronica'. There were no another brand of calculators at that time in Soviet Union – all had to buy and use only Electronika things."

I took a ton of photos of Electronika products at the Popov Museum in St Petersburg — my great uncle, Boris Rachman, is a curator there.


(Thanks, Malatron!)
