Description
This handheld electronic calculator is similar to the TI Business Analyst II. It has a black plastic case with an array of forty small brown rectangular plastic keys. The function of the keys is indicated on the keyboard. In addition to ten digit keys, a decimal point key, and a change sign key, the calculator has a total key and four arithmetic function keys. Other keys are for on/clear, off, and "2nd" (pushed to activate the “dual function” indicated on the keyboard below most of the function keys). The calculator has a variety of statistical, business, and mathematical functions, and limited memory.
Text above the keys reads: TI Money Manager. Text behind this reads: TEXAS INSTRUMENTS. Behind this is an eight-digit LED display. The jack for a charger/adapter is on the right side of the calculator.
Text on the back of the calculator reads: TEXAS INSTRUMENTS (/) electronic calculator (/) SERIAL NO. (/) 054123 LTA 5077 (/) ASSEMBLED IN USA. A sticker on the battery compartment indicates that the calculator was sold by T. K. Enterprises in Lawndale, California. The compartment itself is designed for a nine-volt battery.
There are no screws to easily take apart the calculator. The device has a black plastic zippered case with a loop.
Compare the TI Business Analyst II (1986.0988.087) and the TI-30 (1986.0988.348). Ball & Flamm give a 1977 price of $16.95.
