Notes...

"The Russian in this text is pretty bad - I'm trying to make it into equivalently bad English. Judging by the language used, this could be a military document - military people never say "square" when they can say "a geometric figure of squarish properties" or something similar.
- Greg Escov


Thanks to Greg Escov and Sergei Frolov for their assistance in translating the docment describing the function of the keys on this machine.

That's a rather interesting key on the top right of the keyboard. In fact, there are several unusual keys on this machine - I wonder what they all do?

Here are the functions of some of the keys...

summons number out of register.
stores number into register.
transfers the number into register 1
changes the sign of the number in keyboard register
key of digital reset
0,1, ..., 9 - digital entry keyboard
enters the operation of inverted division
(I think that the normal operation is "x=y/x" and this one is "x=x/y"
the key of complete reset
enters the operation of calculation of square root>
recall the content of register I
resets the keyboard register
enters the operation of multiplication of a constant value
enters the operation of filling-up sum
recalls a number from register P
a breaker of comma setting
