Calculators 3000
Ever wanted to crunch some numbers on an 80s Soviet calculator, or tinker with the easter eggs in the Elektronika B3-34? Now you can! No need for the actual machine — Calculators 3000 has got you covered.

Calculators 3000 (or C3000) lets you get to grips with 26 different Soviet calculators, including the B3-34, MK-61 and MK-52. The UI is an image of the actual calculator, with buttons that can be pressed and a display that shows all inputs and calculations.

The C3000 is both an emulator and simulator. What’s the difference? Well, a simulator imitates the workings of a calculator, while an emulator fully reproduces all of its functions, including the errors and glitches. This makes emulators a great way of playing with the many fascinating undocumented features that make these calculators so interesting.
