American 1776 Handheld Electronic Calculator

Description
This four-function electronic calculator has ten digit keys, four arithmetic function keys, a cancel key and an on/off switch (no equals key—the calculator uses reverse Polish notation). The keys are colored red, white, and blue. A six-digit red LED display is behind the keyboard. A mark above the display reads: American. A mark directly above the keyboard reads: *1776*. The black plastic case opens using a catch on the right side, allowing replacement of the battery. This example has leads for a battery but no battery. A mark on the breadboard inside the calculator reads: C10001.
A detailed description of an example of this calculator is given at the Vintage Technology website.
