Russian RPN calculator series Elektronika MK

[jebem]

I am based in Europe and have been ordering calculators, radios, and electronic components on eBay from the eastern European countries like Bulgaria, Ukraine, Russia among others and never got issues with them.

Delivery time is fair and shipping is kind of cheap when compared to what some western countries ask.

The mk calculators prices seems to be increasing year after year but we can still find good items at a fair price.

New old stock from these countries is not what western people expect. I guess they do not store or handle these goods in the best way, considering the temperature extremes they have there. The mk models are not that old, many were manufactured in the 90's, but when you look to them it seems like 40 years have passed over them.

The most weak feafure imho is the keyboard key's travel that is close to zero. Casio have super keyboards when compared to MK machines. However they register the key entries most of the times, and if that is not acceptable, it is possible to open the machine and repair the keyboard. A good cleaning and a new foam will usually help.

Still they are a good way to spend a few Euros and have a piece of history preserved for future generations.
Oh, and it is still possible to buy the vfd displays (really new stock) for these machines as well.
