Elektronika MK-52

The Elektronika MK-52 (Russian: Электро́ника МК-52) was an RPN-programmable calculator manufactured in the Soviet Union during the years 1983 to 1992. Its original selling price was 115 rubles. The functionality of the MK-52 was identical to that of the Elektronika MK-61, except that the MK-52 had an internal non-volatile EEPROM memory module for permanent data storage, a diagnostic slot, and a slot for ROM modules. The programming language and functionality of the MK-52 and MK-61 calculators were extensions of the earlier MK-54, the B3-34 and B3-21 Elektronika calculators. The MK-52 is the only calculator known to have internal storage in the form of an EEPROM module. All Soviet calculators are renowned for having a very large number of undocumented functions.
