Anixx, wouldn't mind taking your mother to lunch if I am ever in Moscow! Hope she is healthy and well in retirement. I would probably find her career endlessly fascinating, particularly in light of her being a woman.
She is dead unfortunately.

She was a physicist and teacher by education, she worked in school, and then with low-temperature physics but eventually she was invited to work in programming as early as the Ulal computer Ural (computer) - Wikipedia, the free encyclopedia because at the time it was considered a job for physicists. She later programmed in Assembler and PL/I for mainframes.

She worked on a secret job and had no right to tell what she was doing. I only know that it was somehow connected with real-time space communication. Once she wrote a driver for plotter in assembler and we had at home a stack of papers lined for "Preference" cards game (they were plotted by a test program).

We had a lot of punch cards at home and printed machine outputs. I also remember large paper lists (definitely larger than A2) with multiple blocks interconnected with each other with arrows like in Visio diagrams. They were labelled "stack of punch cards", "magnet drum", "remote console" etc. She drew these diagrams with special stencil. She also had a cheat sheet she made herself for deciphering punch cards.

When she lost her work in 1991 we made a good fire of the punch cards near our home.
