Texas Instruments TI Business Analyst II Handheld Electronic Calculator

This handheld electronic calculator is similar to the earlier Business Analyst, but has a larger number of functions and a different display. It has a gold-colored metal front with plastic back and trim, and an array of forty small rectangular plastic keys. In addition to ten digit keys, a decimal point key, and a change sign key (all light brown), the calculator has a total key and four arithmetic function keys (all in dark brown). The remaining keys are white. One is for on/clear, one is for off, and another, marked "2nd," is pushed to activate the “dual function” indicated on the keyboard above many of the white and dark brown keys. The calculator has a variety of statistical, business, and mathematical functions, and limited memory.
Text above the keys reads: TEXAS INSTRUMENTS (/) TI Business Analyst – II (/) Constant Memory. Behind this is an eight-digit LCD display. Text on the back of the calculator reads: TEXAS INSTRUMENTS (/) electronic calculator (/) SER. (/) NO. 2073604 ATA0380. Further text reads: ASSEMBLED IN USA. A stamp on the back reads: 33. A small compartment is designed to hold two tiny batteries.
The device has a black tan plastic carrying sleeve. It is marked on the back: TEXAS INSTRUMENTS.
The online Datamath Museum says the calculator was introduced in 1978 and made through 1983.
