Casio Computer CO., LTD.. Casio FX-7000GA Scientific Graphics Calcualtor

This was the slide rule calculator I used to pass the ICET in 1990 . I like this calc . It is primitive by today's standards but for someone like me this is a powerful tool even now . I own an HP prim . It is far superior in every way but I like this as it has certain functions I can get to much more quickly .

Unfortunately, This Casio FX-7000GA doesn't work. I later acquired a Casio FX-8000G that works perfectly.

i think there is malfunction with graph function

Good
