The machine code and functionality of the MK-52 and MK-61 calculators were extensions of the earlier MK-54, [2] 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. As with many Soviet calculators, the MK-52 has a number of undocumented functions. [4]
The series consisted of the DM10, DM11, DM12, DM15 and DM16. [12] All calculators used the same hardware, but differ in keyboard and firmware (which can be changed with an upgrade port). After the introduction of the larger DM15L , DM41L and DM16L in 2015, the DM11L was added in January 2016 with the DM12L following in February.
The duodecimal system, also known as base twelve or dozenal, is a positional numeral system using twelve as its base.In duodecimal, the number twelve is denoted "10", meaning 1 twelve and 0 units; in the decimal system, this number is instead written as "12" meaning 1 ten and 2 units, and the string "10" means ten.
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
The TI-59 was the first programmable pocket calculator where the manufacturer provided a system for sharing memory between data registers and program storage. The memory is only about twice as large as in the SR-52, but more flexible, and thus the possible number of program steps was four times as high. Contents of this memory are lost when the ...
In June 1982, the "Calculator: Instruction Manual" book was printed by the APX, noted with "User-Written Software for Atari Computers" on the cover, and the program got product ID number APX-20130. [12] In the same year, product CX-8102 was listed in the "Atari Home Computer Product Catalog". On the screenshot, printed in color in the catalog ...

SR-50 (1974) Printed circuit board. Data code 035: 3rd week 1975. The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. . It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other featur
