Description
This alphanumeric programmable graphing handheld calculator has a dark brown plastic case and an array of forty-nine rectangular plastic keys. Three of the keys are shift keys that determine the effect pressing other keys. The calculator is capable of solving and plotting a wide array of problems from arithmetic, trigonometry, algebra, statistics, and calculus. The screen is behind the keyboard. A mark behind that reads: hp HEWLETT (/) PACKARD (/) 48SX SCIENTIFIC EXPANDABLE.
An empty compartment that can hold two expansion cards is at the top of the back. Three corroding AAA batteries were removed from a compartment at the bottom and discarded. A mark above this compartment reads: MADE IN USA 3032A01521 (/) HEWLETT PACKARD 1989. The first four digits of the serial number indicate it was made in the thirty-second week of 1990. The calculator has four rubber feet.
The object was received with a zippered case and a spiral-bound instruction manual HP 48SX Scientific Expandable Owner’s Manual Volume 1. This example is Edition 3, published in May of 1990.
The calculator was used by a faculty member at the U.S. Naval Academy in Annapolis, Maryland.
