The Casio FX-750P — BASIC Pocket Computer
The Casio FX-750P was a programmable pocket computer running BASIC — bridging the gap between scientific calculator and full pocket computer. With its BASIC interpreter and program memory, the FX-750P allowed users to write genuine programs rather than mere keystroke sequences, making it appealing to students and professionals who needed more computational flexibility. Casio’s FX-P series was popular in educational settings throughout the early-to-mid 1980s as an affordable introduction to programming for students who could not afford larger home computers.
