CASIO fx-5200P Scientific Computer teardown

[jebem]

Machine teardown.

Started by undoing the four screws securing the alpha keyboard to the main body.




Then removed the aluminum back cover (not shown).
The two zebra connectors and the common ground spring coil interconnects the alpha keyboard to the main machine body.




And the ground spring coil for the back cover.
Both miniature metal spring coils were missing. I had to order them from a UK seller.



Undoing the screws securing the plastic frame gave access to the main PCA.



Lifting and rotating the main PCA reveals the keyboard assembly.
The LCD display is glued to the front cover and needs to be slightly heated to be removed without damaging the LCD unit.



Back aluminum cover and power switch among other parts.
