-----

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.

Updates:

v2.3:
- fixed state saving instability on leaving app
- fixed layout resizing glitch
- switching calculator off and state saving/loading became faster

- added user preferences for:
* type of on/off and angle mode switches (checkbox/radio buttons or slider)
* vibration intensity
* buttons outline
* labels text size
