The HP 80: Now We’re in Business
Date: 1973
The HP 80 was designed for business people rather than scientists and engineers. Instead of users programming in formulas themselves, the HP 80 had 40 different time-and-money formulas preset, so all the user had to do was plug in the numbers and the calculator would provide an answer for common financial calculations.
