DATAMATH  CALCULATOR  MUSEUM

Additional Pictures 

 

This Canon F-65 scientific calculator manufactured in 1984 reveals a 
very unusual but rigid internal construction. 

The Canon F-65 uses a Toshiba T7767S single-chip calculator circuit
on a small printed circuit board (PCB). 

The internal construction uses a heavy sheet metal to support the connection
of the PCB to both the LC-display and keyboard foil sandwich.
