The MR 610 is a pocket calculator that was developed and manufactured in the GDR by VEB Mikroelektronik "Wilhelm Pieck" Mühlhausen . Due to the range of functions, it is the top model of pocket calculators made in the GDR. The price was initially 730 marks and was later reduced to 205 marks.
The MR 610 is a non-programmable floating point pocket calculator with exponential notation. In addition to the basic arithmetic operations, the pocket calculator has a memory location and trigonometric functions. The pocket calculator also masters hyperbolic trigonometric functions, brackets, statistical functions and the conversion of polar coordinates into Cartesian coordinates , which sets it apart from the smaller MR 609 or SR1 model .
The SLC-8300 pocket calculator from Toshiba , whose processor (T3636) was used in the first models, served as the technical basis . The U826G processor was used in later models, although it is largely compatible. In addition to the processor, the circuit board and the display are largely identical to the SLC-8300, so that both computers have the same keyboard layout and the same display.
The pocket calculator is operated with 2 button cells of the type SR 44 or LR 44.
The MR 610 was produced in different colors. A yellow display glass was used in the first devices, which later gave way to a colorless variant. Blue keys with white lettering or white keys with black lettering were used as function keys. The computer was produced in small numbers in a white housing with white keys.
