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. Please notice that this TI-32 Explorer Plus uses smaller solar cells than an earlier model manufactured in Italy. Compare the two calculators here.
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
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
• 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 comparison table here.
