Description

This is an example of a slightly later version of the Casio fx-7000G graphing calculator introduced by Casio in 1985. The sides of the calculator are black plastic, with a metal keyboard and back. As with earlier calculators, it includes a ten-digit array of keys for entering numbers, a decimal point key, four arithmetic function keys, a delete (clear entry) key, and an all clear key. In addition, it has keys for a wide array of mathematical functions, including square roots, squares, logarithms, natural logarithms, inverses, sines, cosines, tangents, powers, and roots. It is also possible to use the keys in “shift” and “alpha” modes to carry out different functions or enter alphabetic characters. One also may enter programs in a programming language devised by Casio and graph functions, either over a predetermined range or over a range set by the user.

Both programs and results appear on a liquid crystal display that is behind the keyboard.The display could show sixteen characters in each of eight lines. A mark behind the display reads: CASIO SCIENTIFIC CALCULATOR fx-7000GA GRAPHICS. The on/off switch is on the left side. A mark on the back reads: CASIO fx-7000GA (/) RATING: DC 9V 0.04W (/) use BATTERY CR2032 x 3 (/) MADE IN JAPAN (/) BM CASIO COMPUTER CO., LTD. A bar code sticker attached to the back of the calculator reads: SAN JUAN HIGH SCHOOL LIBRARY.

The calculator is stored in a black plastic sleeve marked: CASIO

In addition to requiring less power, the Casio fx-7000GA had a slightly larger type font on its keys and used a keyboard that was in shades of gray rather than silver. In the fx-7000GA, keys for finding estimated values using a regression formula are found in a different mode. In other words, the keys designed for multiplication and division are used somewhat differently.
