In 1996, Casio released this family to update their Power Graphic series. These models vary mainly by amount of supported functions and usable memory. Information on the originals is getting harder to get these days, though manual sections are still available from Casio.


Most of these models are similar to the French Graph 30/35/35+, but some only have 26k of usable memory. All but the fx-7400G+/9750G+ have color support, though this is limited to graphs drawn in green, blue and orange instead of black.
