RetroFX is based on the Casio fx-39 from 1978 made in Japan. Casio made many models with this very popular case design, but functionally, they were all slightly different. The RetroFX display is a reconstruction of the popular green Vacuum Fluorescent Display (VFD) which is actually a small cathode ray tube. RetroFX recreates the original glow given off by these tubes which would typically vary depending on battery strength.
