-----
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.

5 ★ Just like the real calculator, with two important additions: ability to save and recall calculator states, so you don't need to retype programs, and a turbo mode for fast calculations. Moreover, it is two calculators in one, with an easy way to switch betwen the two. Great nostalgic value for me! Thanks!
5 ★ I ordered a real MK 61 from eBay after trying this emulator. The behavior is exactly the same, except the emulator runs programs a little bit faster than the real one. A fun calculator to learn how to use.
5 ★ Спасибо за программу, даже не думал что есть!, а то б быстрее нашел. Ничего не помню сам, но пальцы помнят все! и стек и операции и программирование... Thanks!
5 ★ Super. MK61 calculator as you would know it. Perfectly emulates everything. Simple to use and effective. Great for scientific calculations and engineering. And an exact copy with an ability to work at greater speed when press on the screen. Would give 10 stars. Remember accuracy of x^y function is an issue in the original MK61. Wold be great if developer could ad an option to enable greater precision.
5 ★ У меня был МК-61 примерно в 1989-м и у меня до сих пор есть 2-3 книги, одна из которых с играми для этого программируемого калькулятора. Будет чем заняться на выходных с моим 11-летним сыном :) Спасибо, Станислав!
5 ★ To get access to the menu on meizu m2/m3/m5 (they use a gesture to open recent apps list, not a button) you have to enable SmartTouch feature (on-screen button) and set "open menu" action on slide up.
5 ★ Присоединяюсь к человеку, который хотел бы поставить 10 звёзд. Потрясающее приложение. Вот уже два часа медленно, но верно вспоминаю, как пользоваться этой машинкой. Даже все чудачества, которые были в оригинальном калькуляторе, всё понимает. Это целая эпоха. Тем, кто сейчас закончил институт и пишет на объектно-риентированных - не понять. Было правило, любую программу можно уменьшить на 1 байт. И оно работало. И мы соревновались в этом. И это всего при 105 байтах программы.
5 ★ My best friend through my university. Personally I would add some advanced features like context help for keys or mode to view and edit whole program fast. Anyway great job
5 ★ Великолепный генератор ностальгии :-) Интересно, тут зггоги и эггоги (числа больше 1е100) так же чудесно будут себя вести?
5 ★ Дал бы 10 звёзд если мог. Он даже эмулирует еггогологию! Такое впечатление что портирована родная прошивка.
4 ★ At least ENGLISH... GOOD APP, IT APPEARS TO BE A WELL DONE JOB... CONGRATULATIONS!
5 ★ I wonder if there are any plans to support MK-52 (along with "A^" and "^v" commands)?
5 ★ Awesome app. Stylish and functional. The only thing I would see is a faster response between key presses. Thanks a lot.
5 ★ Long pressing square button doesn't work on android 8.1
5 ★ Очень ждал ! Наконец то пройду весь Кон-Тики )
