The HP-15C is a high-end scientific programmable calculator of Hewlett-Packard's HP Voyager series, Voyager series produced between 1982 and 1989. The "C" in the name refers to the continuous memory, such that the calculator retains it's state when switched off. Models HP-15C The HP-15C is a high-end scientific pocket calculator with a root-solver and numerical integration. A member of Hewlett-Packard HP Voyager series, Voyager series of programmable calculators, it was produced between 1982 and 1989. The calculator is able to handle complex numbers and matrix operations. Although out of production, its popularity has led to high prices on the used market. The HP-15C was a replacement for the HP-34C. The 15C used bulk CMOS technology for its processor, resulting in very low power consumption. HP 15C Limited Edition After showing a prototype labelled ''HP 15c+'' at the HHC 2010, HP announced the ''HP 15C Limited Edition'' (NW250AA) on 1 September 2011. It is based o ...

Programmable Calculator
Programmable calculators are calculators that can automatically carry out a sequence of operations under the control of a stored computer programming, program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than for general-purpose use. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory. Since the early 1990s, most of these flexible handheld units belong to the class of graphing calculators. Before the mass-manufacture of inexpensive dot-matrix LCDs, however, programmable calculators usually featured a one-line numeric or alphanumeric display. The Big Four manufacturer ...
