- Description
- This credit card-sized, lightweight handheld electronic calculator has an aluminum case and brown plastic keys. In addition to an array of ten digit keys, a decimal point key, and a total key, it has a column of four arithmetic function keys immediately to the right of the digit keys, and a column with a percentage key and three memory keys on the far right. The square root, C (clear), and AC (all clear) keys are left of the digit keys. The on/off switch is next to the AC key.
- The eight-digit liquid crystal display is above and to the left of the keyboard. A mark below it reads: CASIO LC-785 (/) ELECTRONIC CALCULATOR. A mark on the back reads: CASIO LC-785B (/) BM MADE IN JAPAN RATING: DC 3V 0.00025W (/) USE BATTERY 1.5Vx2.
- A screw on the left side of the back holds it to the front. Unscrewing it reveals the circuitry. A sticker on the inside of the back of the case reads: 1D202A.
- The calculator fits in a leather pouch which also has a booklet of instructions printed in English, German, French, Spanish and Italian. A mark on the pouch reads: CASIO.
- Several advertisements for the LC-785 appeared in late 1981. None found specifically mentions the LC-785B. The Casio website lists the LC-785 as a product of Casio in 1982.
