The Explorer Plus (aka TI-32) is very similar to the Galaxy 40x but uses the housing of the Math Explorer. Within Europe an identical calculator was sold as TI-40 Solar.

There is no relationship to the previous TI-32.

Dismantling this calculator manufactured by Nam Tai Electronics, Inc. in May 1997 reveals a typical "far-east" design with a single-chip calculator circuit in COB-technology.

Later the same keyboard layout was used with a more stylish housing. Compare it here.

Texas Instruments was always listening for the demands of the classroom. Read some guidelines how to select the right calculator to ensure long-term satisfaction:

	Solar Power: Eliminates the need for batteries. The TI ANYLITE™ technology allows operation even in low light.
	Durability: Plastic keys are tougher and more tamper-proof than rubber keys. An extra window protects the LCD display and the solar cells.
	Keyboard: Color coding helps children quickly identify functional key groupings. Large, well spaced keys are easier to find and press.
	Packaging: With a convenient storage caddy 10 or even 30 calculators are grouped together.
	Functions: Choose a model with only the specific functions you need. Unnecessary functions clutter the keyboard and may impede a student's understanding of the concepts.

In the year 1995 Texas Instruments provided a total of 6 different calculators (not counting the Graphing Calculators TI-80, TI-81, TI-82 and TI-85) to meet the above demands. View a comparision table here.
