The first Soviet programmable calculator was the Elektronika B3-21.
Commercialized since 1978, B3-21 had 60 program steps and 8 storage registers.
She used Reverse Polish Notation (RPN).
His little sister the MK-47 was the only programmable calculator equipped with a magnetic card reader like the TI59.
Unfortunately, documents and photographs on this machine seem to exist anymore.

There is also a Windows emulator for Soviet calculators :

It emulates 21 different calculators including 8 programmables.
Very nice achievement, despite a few bugs.
