Hanimex 807 Handheld Electronic Calculator

Hanimex was an Australian import-export firm, founded after WWII by German refugee Jack Hannes. The name is an abbreviation for Hannes Import Export. The company sold a variety of cameras, lenses, slide projectors and, for a shorter time, handheld electronic calculators. This example has a plastic case with metal trim and twenty three rectangular plastic keys. These include ten digit keys, a decimal point key, a total key, four keys for arithmetic functions, three memory keys, a percentage key, a square root key, a clear entry key and a clear key. The on/off switch is left of the three uppermost keys. Behind the keyboard is an eight-digit LED display. Text above the display reads: HANIMEX 807. The top edge has a socket for a power adopter. The calculator has a black plastic carrying case.
The back of the calculator has a battery compartment at the top to hold two AA batteries. Its cover is loose. A sticker below the compartment reads: Electronic Calculator (/) DC 3V (/) Use 2 pieces “UM3” (/) or “AA” Batteries. A sticker inside the compartment reads: Serial No. H61896.
The Australian firm of Hanimex Pty. Ltd. applied for a U.S. trademark for electronic calculators in 1979, stating that the first use of the trademark in commerce had been in February of that year. The trademark was granted in 1982 and cancelled in 1989.
Compare the general arrangement of the keyboard (though not the display) to the Casio LC-825 (see 1986.0988.213)
