Around 1990, the Power Graphic series introduced: F1 through F6 shortcut keys which enabled significantly greater ease of use, polar, parametric and inequality graphs; box and factor zoom; multiple graph scrolling; range initialization; integration; matrix mode; fractions; permutations; combinations; normal probabilities; SI unit symbols; Models: fx-7700G, fx-7700GB, fx-8700G, fx-8700GB.
Also made was the low-end fx-6300G (French: fx-6800G) with a smaller screen and fewer features, and the fx-6200G which didn't have any programming functionality.
For instance, it does not have the commands Getkey, Locate, Text or matrices or complex numbers, and the screen is smaller.
There are community written tools for accessing the ROM-DOS operating system thus allowing C and Pascal compilers to be used.
In 2009, the GII models were produced along with a corresponding OS update for the original 9860G, now containing features such as GCD, LCM, modulus operator, random integer generation, units conversion, string functions, and new probability and inverse probability distributions available within programs.
The architecture of the 9750GII is similar to the 9860GII and therefore the former can be unofficially upgraded to the later Operating System offering more features particularly pretty printed equations and Vector arithmetic.
The 7400, 9750 and 9860 GIII series was introduced in 2020 and includes a modern design language, increase in user memory for programming, support for implicit multiplication and a faster processor clock-speed and a MicroPython interpreter.
[4] The Prizm is permitted on all major standardized tests including ACT, SAT, AP, GCSE and GCE examinations.
[10] An updated model, called the fx-CG50 or Graph 90+E in France, was released in January 2017[11] with a more modern design (similar to the Classwiz scientific calculators) and a faster processor.
The Classwiz CG Series was announced by Casio at the National Council of Teachers of Mathematics (NCTM) conference at Chicago, United States in late September 2024.
[12][13] In France, the Classwiz CG Series was introduced in March 2024 with reduced functionality and is known as the Graph Math +.
A non-programmable variant with a monochrome screen called the Graph Math Light was also introduced in the French market for exams where programmable calculators are not allowed.
The second-generation programming language includes conditional and iterative functions and the ability for real-time user interaction with the Getkey command.
However, due to the fact that Casio hasn't published a Software Development Kit for the fx-CG10/20/50, it is reasonably hard for a user to create their own game.
