Advertisement for the Sharp
Compet 22(CS-22C) electronic
calculator
Electronics Magazine, July 7, 1969
This is an advertisement for an updated version of the original
Sharp Compet 22 (Model CS-22A), which apparently relied
on more sophisticated MOS integrated circuits to make a new model of the calculator designated
the Model CS-22C.
Functionally the CS-22A and CS-22C were identical, but the CS-22C was priced a bit
lower than the original CS-22A due to the reduction in circuit board complexity brought on by the
use of fewer, more complex ICs.
