Unitrex Mini 8 Handheld Electronic Calculator, Back View
Description:

This handheld electronic calculator has an off-white plastic case and an array of nineteen rectangular plastic keys. These include ten digit keys, a decimal point key, four arithmetic function keys, a total key, a percentage key, a clear entry key, and a clear key. Above the keyboard on the right is the on/off switch. A mark next to it reads: UNITREX (/) mini 8.

Behind these is an eight-digit red LED display. A jack for a power adapter is along the back edge.

The back has a compartment for a nine-volt battery. A mark on the back of the cover of this compartment reads: A57K11831. Text impressed into the calculator at the base of the back reads: UNITREX mini 8 (/) EIKO BUSINESS MACHINE CO. LTD. (/) DC 9V 0.5W (/) MADE IN JAPAN.

The case is very similar to the Unitrex Mini Handy 80R (1986.0988.018).
