- Description
- This handheld electronic calculator has a gray and cream-colored plastic case, and square plastic keys. In addition to an array of ten digit keys, it has a decimal point key, a total key, and four arithmetic function keys to the right of the digit keys. Immediately above the digit keys are AC (all clear), C (clear entry), square root, and percentage keys. Above this is a switch for setting the result to floating point arithmetic or to round off with two decimal points, and three memory keys.
- Behind the keyboard is an eight-digit vacuum fluorescent display. A mark above this reads: CASIO memory-8A (/) ELECTRONIC CALCULATOR.
- The back of the calculator has a compartment for two batteries. The batteries and compartment cover are lacking. A sticker inside the compartment reads: 4036264. A tag below the battery compartment reads: CASIO memory-8A (/) BATTERY SUPPLY 1.5Vx2 (/) or use AC ADAPTOR AD-2S (/) 0.2W (/) CD-813 MADE IN JAPAN (/) BM CASIO COMPUTER CO., LTD. The socket for the adapter is along the top edge.
- Opening the calculator reveals two circuit boards with assorted circuits. The largest of these has the inscription: NEC (/) μP0977C R56696. This object is somewhat different from the Casio Memory-8A described at the Vintage Technology website.
- The calculator fits in a black plastic sleeve. A mark on the sleeve reads: JAPAN.
- According to the Casio web site, this model was introduced in 1974. An October 1975 advertisement for several Casio calculators with memory asked: “When you’ve got a Casio Memory, who needs an elephant?" It indicates that the suggested retail price of this model was then $24.95. Further advertisements appeared in 1976.
