- Description
- This handheld electronic calculator has some but not all of the functions of a scientific calculator. It has a metal and plastic case with twenty rounded square keys and ten rounded rectangular keys, for a total of thirty plastic keys. These include ten digit keys, a decimal point key, a total key, four arithmetic function keys, three memory keys, and a change sign key. Keys in the top row are for powers, squares, inverses, pi, clear/clear entry, “MU Δ%,” “% 5/4,” %, square roots, and dollars. To the right of the keyboard is a switch that can be set at the values 5/4, A, 0, 2, 4, and F. This may relate to the position of the decimal point.
- Above the keys is an eight-digit green fluorescent display. A mark above it reads: SHARP ELSI MATE (/) EL-8118 (/) Electronic Calculator. To the right is an on/off switch. A jack for a power adapter is along the back edge.
- The back of the calculator has a compartment at the top that holds two AA batteries. A mark below this reads: ELECTRONIC CALCULATOR (/) EL – 8118. It also reads: SHARP CORPORATION (/) MADE IN KOREA. Below this is a paper sticker with American, British, Canadian, Swedish, and Australian patent numbers. The largest U.S. patent number is 3621219.
