The first generation of the SR-10 uses
still the LED-modules known from the
famous Datamath calculator.

Up to now we are missing a SR-11
with the 6-digit LED-modules.


Texas Instruments made several prototype
calculators with an additional lens-stripe
on top of the 6-digit LED-modules.

The picture on the left was taken from an
early SR-10 prototype, the picture below
from a SR-11 prototype.

The final display construction of the SR-10
with a printed circuit board (PCB) with
discrete LED-modules and a lens-stripe.

The SR-11 with an identical display board.
This construction was used with the later
SR-16, SR-50 and SR-51 calculators.
