The HP 30b Business Professional is a powerful business calculator, but it may lack a function important to you. The HP 30b programming functions allow you to create up to ten programs to fulfill your needs. In order to keep the calculator keyboard clear and consistent, the programming functions are not written on the keyboard.

This is designed to be placed on the top surface of the calculator and left in place for the life of the calculator. If you are interested in programming the calculator, you will need to place the overlay on your keyboard before getting started.
