DATAMATH  CALCULATOR  MUSEUM

Additional Pictures 

 

The differences between the Longines Symphonette calculator 
manufactured by Texas Instruments and the original calculator
 - the famous Datamath - are small. 

Please use the two pictures to compare the details:

Olive green housing vs. the creme coloured of the original.

Grey keys vs. the white and creme coloured.

Longines Symphonette label vs. the Datamath label.

Minor changes on the backward label. Notice that 
the TI nameplate is still in place.
