Dib2Calc vs Extended emulator of МК 61/54
Side-by-side comparison of two open source alternatives
Dib2Calc
Dib2Calc (aka Dibdib Calculator) The crazy calculator. A short introduction is provided when you start it for the first time. The goal is to provide many specific functions, especially for text data and data structures, not only for calculating numbers. This is one of the reasons why it makes use of the so-called RPN notation: instead of typing 4 '+' 3 '=', you type 4, 3, '+' (but you can also type 4 5 6, 3, '+' resulting in 7 8 9, because 7=4+3, 8=5+3, 9=6+3 ...) Just try it out. Once you get used to it, you will love it :-) Your data is protected (encrypted) if you use your own access code and password. In case you have a lot of data, make sure to save it to the device's Download area via the SAVTO function (as a backup). See https://gitlab.com/dibdib/dib2calc for more information (and https://gitlab.com/dibdib/dib2calc/-/blob/master/known_issues.md for known issues).
Extended emulator of МК 61/54
МК 61 was the best seller of all USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52). 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. It's an extended version of the original emulator МК 61/54 by Stanislav Borutsky (https://play.google.com/store/apps/details?id=com.cax.pmk). This version allows to export/import programs from external files and contains some UI improvements. Hint 0: you can found the list of all tips in the About dialog Hint 1: touch calculator's indicator to toggle slow/fast mode. Indicator's blinking looks better in slow mode. Hint 2: you can choose between MK-61 and MK-54 using menu option that becomes visible when calculator is switched off. Hint 3: with the menu "Import" you can import programs from external files, several such programs you can find in https://xvadim.github.io/xbasoft/pmk/pmk.html Hit 4: you can open menu by long tap on the "Вкл" label.
