Just
a cost optimzed version of the original Little
Professor. Texas Instruments dropped even the label on the backside of the
toy to reduce the bill of material a few cents.
More
dramatic changes took place inside the calculator! The housing of the TMS0975
single-chip calculator circuit was shrinked by approximately 30 percent.
During 1980 the Little Professor got additional keys for ON/OFF and LEVEL. Compare them here.
