casio fx-7000g

rubber keys and a graphic display. is this where graph plotting began?

i remember when this model came out and it seemed quite impressive at the time. the large display could show recent results and plot graphs. the machine is physically larger than previous pocket models, to accommodate the display, but still quite slim.

with this model, the casio programming language changed. rather than steps and jumps, it changed to a more formula oriented concept with strange symbols for loops, input and output. nevertheless, the language is still a proper programming model with conditional jumps, labels and subroutines. the same language was deployed in other models like the fx-4000p.

thank you for your purchase of the casio fx-7000g. this unit is a totally new type of advanced programmable computer. besides 82 scientific functions, graph functions also make it possible to produce a wide variety of useful graphs.

manual computations can be easily performed following written formulas (true algebraic logic). a reply function is provided that allows confirmation or correction when key operation errors occur. programs can also be input following true algebraic logic, so repeat and/or complex computations are simplified.

there are 26 memories (a-z) which can be extended to 78 or up to 422 program steps. it is powered by 3 cr2032 lithium cells. yes 3! which makes a new set of batteries cost a lot more than non-graphing models, and it uses them faster too.
