The '''Elektronika MK-52''' is a RPN scientific programmable calculator produced by Elektronika in Ukraine starting in 1985<ref>[https://elektronika.su/en/calculators/elektronika-mk-52/]https://elektronika.su/en/calculators/elektronika-mk-52/</ref>. | The '''Elektronika MK-52''' is a RPN scientific programmable calculator produced by Elektronika in Ukraine starting in 1985<ref>[https://elektronika.su/en/calculators/elektronika-mk-52/]https://elektronika.su/en/calculators/elektronika-mk-52/</ref>. The "MK" prefix is an abbreviation for микрокалькулятор; "micro calculator". | ||
The calculator runs on 6 volts supplied by either an external DC power adapter, or 4x AA sized batteries. The external power adapter originally used a 3 pin port, but that was changed to a 2 pin port in 1992. | |||
There are 4 hinged doors along the top of the calculator, 3 of the same width (43mm), and the one on the right is slightly wider (58mm). The 2 on the left can be "opened" but there are no holes in the plastic shell of the calculator to give access to anything. There are holes in the plastic shell behind the 2 doors to the right, however, only the right most wide door has a header to the PCB behind it. | |||
