Among USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52), MK-61 was the most selling one.
Calculators are emulated on microcode level so they behave exactly like the original devices, including all non-documented features and inaccurate calculations. For ease of use application features saving and loading emulation states.
This app's emulation engine Java code is based on C++ source of Felix Lazarev's emu145 project.
Emulation was highly optimized for speed and should run in real time on any phone.
Enjoy with UptoPlay the online game MK 61/54.

Comments:
On/Off switch and real calculator speed are hilarious. Love this app. Still have the real thing too.
Great emulation. Works like the real thing.
Elektronika MK52 is the first handheld i obtained in the school. The old guy is still around, almost like in day one, btw. The line of these machines was famous with the endless undocumented features, and this emulator seems to support them. I followed the description of the app and have seen how the base emulator was developed (with all the reverse-engineering methots, etc). Very good work! P.S. No ads and ridiculous permissions, one more big plus for the author!
Very nice app! It would be interesting to document if there are features that have not been completely implemented? The MK61 seems to be known for its "extra" undocumented features. rgds
My lack of education is frustrating. New goal, learn why one would want this app. Then how to use it.'
