DATAMATH  CALCULATOR  MUSEUM

Additional Pictures 

 

The first version of the SR-11 uses the 
6-digit display modules known from the
Datamath calculator.

The second version of the SR-11 with
the 12 discrete LED-modules found 
later in the SR-50.

The printed circuit board of the SR-10 looks really similiar to the pictured 
SR-11 boards on the left.
