Mickey Mouse's School Book Handheld Electronic Calculator and Electronic Game

<< >>
Walt Disney’s cartoon character Mickey Mouse has appeared on American consumer goods ranging from yo-yos to lunch boxes to watches to handheld electronic calculators. This device can be used either to do calculations or, in quiz mode, as an educational game.
It has a bright yellow plastic case with a black and white plastic cutout of Mickey Mouse on the cover. Mickey Mouse holds a sheet that reads: MICKEY (/) MOUSE’S (/) SCHOOL (/) BOOK. Opening the latch reveals a calculator with eighteen rectangular plastic keys. These include ten digit keys, a decimal point key, a clear key, four arithmetic function keys, a longer bar marked “?”, and a total key. Below these keys is a switch that may be set either at “Calc” or “Quiz.” Next to this switch is the on/off switch.
Behind the keyboard is a green fluorescent display. Above this is a green light marked “Right” and a red one marked “Wrong;” above this is a plastic cutout of the face of Mickey Mouse. A space at the top of the calculator would hold two batteries. It presently has no batteries and the cover is missing. A jack for a power adapter is on the top edge.
Next to the calculator is a space that could hold a ruler. This example has no ruler. The inside of the lid of the case – right of the calculator when it is open – hold a pad of paper with odd numbers jotted on it. A sticker below the paper on the inside of the lid reads: IN ORDER TO REFILL PAD, PLEASE NOTE, (/) PAD SIZE TO FIT INTO YOUR MICKEY MOUSE (/) NOTE BOOK WOULD BE (89x149x6m/m SIZE) (/) 007577.
The back of the case has another image of Mickey Mouse. A mark in the molded plastic near the bottom reads: MADE IN TAIWAN.
The calculator dates from between 1974, when inexpensive electronic calculators became common, and 1986, when it was given to the Smithsonian. Hence a rough date of 1980. No specific printed references to this calculator found. It resembles some Unisonic calculators.
