The Casio fx-7000G is the world’s first graphing calculator.
I bought this calculator from a 200 DM money gift I got from my uncle at Christmas 1985.
Restauration Works
Cleaned the case and keys.
Known Issues
The display has some minor delamination streaks from old age (called “vinegar syndrome”). The defect is a cosmetical issue, and does not affect the pixel presentation at all. However it’s not reversible and tends to become worse over time.
