This Rockwell-Anita calculator is unusual for two reasons:

This is explained by this model being a Unicom machine relabelled with the ANITA name. Unicom was the trade name of the calculators manufactured by the semiconductor company American Micro-systems Inc. Like Sumlock Anita, it was bought by Rockwell in 1972 which continued to manufacture the Unicom models for a time. See also the Rockwell-ANITA 102 hand-held calculator.
