The
SR-16 II followed soon in the steps of the rare and wonderful SR-16.
It uses a very similar housing to the SR-50A but gave a
cheap appearance with the few black keys and the printed keyplate. The rare SR-40
prototype was sandwiched between the SR-50A
and SR-16 II.
This calculator gave a first view into the future of Texas Instruments - the TI-30.
A rare sibbling of the SR-16 II was sold with the CONCEPT III. All three known CONCEPT models based on Texas Instruments calculators seem to be very rare, don't miss the CONCEPT I and CONCEPT II.
You'll find similar calculators in the Basic-Album, view for example the TI-2550 II. Very unusual is the poor calculating precision, the internal resolution is only 8 digits. If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.
