content: This handheld electronic calculator is programmable and prints on a paper tape. It has thirty-one rectangular plastic keys. Most keys have three functions, one indicated on the keytop, one (in blue) on the front edge of the key and one (in gold) on the keyboard in back of the keys. Behind the keyboard are two switches and a red LED display. Behind this is the printing mechanism that displays up to eight digits of a result. A mark at the front of the calculator reads: hp HEWLETT-PACKARD 19C. A mark at the bottom of the keyboard reads: Continuous Memory. This phrase signifies that programs remained stored in the calculator after the device was turned off.

A battery pack with four batteries was removed from the compartment. A mark on the case below the compartment reads: 1802A00967.
