Casio FX-870P Emulator

A browser-based emulator for the Casio FX-870P, a 1986 programmable pocket computer, has been developed in TypeScript and Vue 3. The emulator faithfully reproduces the original hardware including the Hitachi HD61700 CPU, 96×64 pixel LCD display, 83-key keyboard, and optional floppy disk drive, while adding web-friendly features like responsive scaling and direct keyboard mapping. The project is a port of the original Delphi reference implementation, making the emulator accessible to a wider audience online.
