The Casio fx-7000G is notable for being the world's first graphing calculator.

It came with 422 bytes of memory and it was possible to store up to ten programs in 10 program slots. 422 bytes is not much by today's standards but with its heavily tokenised programming language, programs performing fairly large tasks could be written.

It was a milestone in the history of pocket calculators when Casio introduced with the fx-7000G the world's first Graphing calculator. The display could be switched between the character mode offering 8 lines of 16 characters each, and a pure graphics mode with an array of 63*95 addressable dots. Even todays Graphing calculators like the TI-83 Plus kept this display format, main differences are the data and program memory sizes. Instead of limited 422 program steps todays calculators deal with megabyte instead the bytes.
