Circuit board

The circuit board. The large integrated circuits are the DS8881N and MM5799NBX/N.

In the mid to late 1970s there was little profit in the basic four-function calculator. Companies produced special-purpose calculators to make profits in sectors where there was little competition. There were a few other models of calculator with functions for use in betting that were sold in this period.
