Description

From the listing uploaded by “apps”.

Emulator of "Electronika MK 61" and "Electronika MK-54" RPN programmable calculators. *************************************************************************************** *** LONG-PRESS 'LIST OF ACTIVE APPS' BUTTON TO ENTER MENU *** *************************************************************************************** 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. ----- 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.
