The development of programmable handheld calculators was an obvious next step. The first programmable calculator was created by the legendary Compucorp in 1968, known as the 323.

In the early days, most programmable calculators used a very simplified programming language, often based either on recording actual keystrokes or bytecode if the keystrokes were merged. Calculators supporting such programming were Turing-complete if they supported both conditional statements and indirect addressing of memory. Notable examples of Turing complete calculators were Casio FX-602P and the HP-41C.

In the early 1970s, Hewlett-Packard (HP) introduced the HP-65, the first magnetic card-programmable handheld calculator. The HP-65 was followed by the HP-67, which added additional memory and more built-in functions. The HP-41C, introduced in 1979, was the first calculator to use alphanumeric display and have a complete computer-like programming model.

By the 1980s, programmable calculators had become more advanced, with more memory, better programming languages, and more built-in functions. The 1980s also saw the introduction of graphing calculators, which allowed users to graph functions and perform more advanced calculations.

Today, programmable calculators continue to evolve, with more advanced programming languages, larger displays, and more powerful processors. They are used by professionals, students, and hobbyists alike for a variety of tasks, including engineering, finance, and scientific research.
