Memory usage with listed categories can be viewed from a system manager menu. The storage memory is used to stored add-in applications, which can be loaded through a computer. The program memory is used to store program files, calculator settings, and variables for matrices, statistics, graphs, tables, equations, etc. It was the first time that Casio adopted a flash storage into its calculator production. The calculators come with a main program memory (RAM) of 146 kilobytes and a storage flash memory of 768 kilobytes. In the Graph 100+, the buttons EXP and a b/ c are replaced by ×10 x and a+ b/ c, respectively. In terms of keypads, there are two differences between the Algebra FX 2.0 and its French version Graph 100+.

The top part consists of buttons F1 to F6, used to select function menu tips. The SHIFT and ALPHA keys are used to access functions and alphabets appearing on top of buttons. The middle part contains more sophisticated mathematical function keys, SHIFT and ALPHA keys, and directional pads. The lower part of the keyboard consists of numeric and operational keys, where the EXE button is used to execute calculations and select commands. The calculator's keyboard can be separated into the lower, middle, and top parts. The display's contrast can be adjusted from a system manager menu.

#Casio fa 123 series
The Algebra FX 2.0 series incorporates a black-and-white LCD Dot-Matrix display with a graphic resolution of 128 by 64 pixels. The calculators weigh about 213 grams including batteries. The back-up battery can operate for about two years. Based on the manufacturer's data sheet, zinc-carbon R03 AAA batteries and alkaline LR03 batteries can supply power for 140 hours and 230 hours for continuous display of main menu. The calculators consume power at the rate of 0.2 W. All program memories will be deleted if both primary power and memory backup power are removed or down. It also uses one lithium battery CR2032 for a memory backup when the primary power is down. The calculators are powered by four AAA batteries used for primary power. However, the Graph 100+ was continued to be sold in France until 2015, a time when Casio removed the product from its website.
#Casio fa 123 plus
The Algebra FX 2.0 Plus was discontinued in 2003 and succeeded by the Casio ClassPad series, where the calculators have stylus-based touch screens. The Graph 100 and the Graph 100+ were respectively the Algebra FX 2.0 and the Algebra FX 2.0 Plus. Casio had used different product names in France, following their French predecessors. The calculators were sold to different parts of the world. The Casio's CAS was mainly developed by its R&D team and Professor John Kenelly of Clemson University. The computer algebra system in the Algebra FX series had been largely improved from the previous model so that more mathematical functions were added. The Algebra FX series was the successor of the CFX-9970G, the first Casio calculator with computer algebra system (CAS) released in 1998. They were aimed at helping students learn to solve algebra problems, where step-by-step solutions could be auto-generated. The calculators were designed for usages in the classroom, where target markets were students and educators. The modified model Algebra FX 2.0 Plus was released in 2001 with additional functionalities in the financial calculation, statistics, and differential equations. In 1999, Casio released a graphing calculator Algebra FX 2.0.
#Casio fa 123 install
long story short, my home pc is dead, got an exam in two days, just brought a cable so i can cram some notes in, ran the FA122 program on the uni computers except that i dont have permission to install stuff permanently, only each time i log on and then anything ive installed gets deleted, which is fair enough otherwise people would install heaps of crap and cause more troubles.
