TI SR-10
Manufactured by: Texas Instruments     Model: SR-10     Year: 1973

This early calculator was a favorite of engineers because did more than the basic four functions. In fact, it was marketed as an electronic slide rule calculator. Better calculators were to follow, but this was definitely drool-worthy at the time of release. (Note: Julie got one as a high school graduation gift.)
