Details:

The Casio  FX-7000G is one of several programmable calculators which were introduced in the early 80’s.

It is equipped with solid state  memory and lots of mathematical as well as statistical functions.  The memory however, is volatile.

Batteries are supposed to last 100 hours.  The inside of the battery cover mentions that a reset is necessary after battery replacement. After a reset all programs and data are lost.  Also if for any reason the calculator doesn’t respond, a reset may be required.

The LCD display is capable of displaying 8 lines of 16 characters or a 64 X 96 pixel graph.

Several publications in 1986 state that it is the world's first graphing calculator available to the public.
