Casio Hl-807 Handheld Electronic Calculator


The case of this handheld electronic calculator is a cream-colored plastic on top and a black plastic on the bottom. The keyboard has an array of square brown plastic keys, including ten digit keys, a decimal point key, and a total key. Four keys for arithmetic functions are to the right of the digit keys. A column to the left of the digit keys has a memory key, a percentage key, a C (clear entry) key, and an AC (all clear) key.

The eight-digit yellow liquid crystal display is behind the keyboard. A tag behind it reads: CASIO HL-807 (/) ELECTRONIC CALCULATOR. A switch is on the left side. There is no power adapter or socket for one.

Text on the back of the case reads: CASIO HL-807 (/) RATING: DC 3V=0.00026W (/) use BATTERY 1.5Vx2 (/) MADE IN JAPAN (/) BM CASIO COMPUTER CO. LTD.

Two screws (one missing in this example) hold together the front and back of the case. Unscrewing them allows one to change the two AA batteries (this example has no batteries.) A sticker on the inside of the back of the case reads: 2279978. A mark on the Hitachi chip reads: HD43111A (/) 9J 43.
