The Elektronika MK-61 is one of the most powerful programmable (non-BASIC) soviet calculators ever manufactured. It was extremely popular, being compatible with the B3-34 series machines. This machine was quite versatile, presenting the quite popular RPN entry system and 105 steps of program memory. It was a real workhorse.
The MK-61 has 105 steps of volatile program memory and 15 memory registers. It functions using either three AA-size battery cells or a wall plug. It has a ten-digit (eight digit mantissa, two digit exponent) green vacuum fluorescent display.
These calculators have been made in 1989-1991, USSR.
Calculators are in very good cosmetic condition. Have been tested and guaranteed to be fully working.
Old soviet electrolytic capacitors are replaced with new ones. So the calculator will work for decades.
Recommended: USB power supply cable for Elektronika Calculators - save on batteries.
