datamath may be wrong on that date. The earliest **newspaper** advertisement for the Corvus 500 comes from August 23, 1975 and refers to it as the "new" Corvus 500.

We all know we can't trust marketing...everything is new!


Of course, the TI SR-50 was introduced on January 15, 1974, so perhaps it really was the first with hyperbolics ?
