Why limit yourself to your small screen on the phone? Run Extended emulator of МК 61/54, an app by Vadym Khokhlov, best experienced on your PC or Mac with BlueStacks, the world’s #1 Android emulator.
So with this app, you’re basically getting a spot-on emulator of those old Soviet programmable calculators—specifically the MK-61 and MK-54 models that were everywhere back in the 80s. It copies those calculators down to the quirks and little inaccuracies, which is kind of funny and cool if you like that sort of retro stuff. All the odd undocumented things those originals would do, this app does too. It’s not just for show; the buttons and display behave just like the real thing, so it’s perfect if someone remembers those devices or wants to try out vintage programming on a calculator.
Using it on a PC with BlueStacks feels smooth, and you can easily save and load states, so messing with long or complex programs isn’t a pain. Switching between models is just a quick menu option—the app actually lets you toggle between the MK-61 and MK-54 calculators—and there are a few extra conveniences like importing or exporting programs. The UI doesn’t get in the way, but things like toggling between slow and fast indicator modes is there for anyone who cares about the little details, like the look of the display. It even supports importing old programs from files, and there are some collections online to try out, so if you’re into vintage tech or calculator programming, this feels like the real deal, just way easier to use and share on a modern PC. All the tips and extra touches are tucked into the app, so it’s pretty accessible whether you’re a total beginner or someone who used the original calculators back in the day.
Big screen. Bigger performance. Use BlueStacks on your PC or Mac to run your favorite apps.
