CASIO fx-5200P Scientific Computer teardown

[Gamo]

Very nice Tear-down images.

I just acquired a Casio FC-100 (No Programmable feature)
This is a Financial Consultant calculator.

When I got this the display was all dark and very hard to read numbers.
After watching YouTube on how to fix dark spot on calculator display I
decided to fix this and all go well.

As shown in this attachment the NPV key is upside down and
the display shown all digits with number 8 to show all segment is working.

Remark: The upside down NPV key was like that when I got it, forgot to put it
the right way when I fix the display. I just took time and carefully fix the display
that I totally forgot to change that NPV key.
