These calculators do not distinguish between real and integer numbers when calculating power functions, they always do them as x^y=10^(y*lg(x)). And unlike many Casios and TIs, they DO NOT hold one or two more digits in memory, they hold only what they display...

BTW if you have an Elektronika MK 85 you can use MK 61’s charger.

I think someone here even did an English translation of the manuals.

Russia's the only country that can currently send people into space (and bring them home!), so they must be doing something right.

Thanks for the replies, everyone!!! ... I must admit to being particularly taken with the brutalism of the MK 52... it even has a row of expansion ports up top... I wonder what they were for?

If you want to dive deeper into that misterious port to left, here are some links that
