Texas Instruments introduced the TI-108 in 1986 as a slightly modification of the TI-1706 II. While the design and even printed circuit board (PCB) of the two calculators are identical, sports the TI-108 a [+/-] key instead the [AC] key found with the TI-1706 II. The successor of the TI-1706 II, called TI-1106, is 100% identical with this early TI-108.

Dismantling this first generation TI-108 reveals with the S32B-II 1K designation on the printed circuit board (PCB) a hint to its contract manufacturer. It seems to be a design of Kinpo Electronics, Inc., manufactured in their Cal-Comp Electronics plant.

We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.

Texas Instruments updated the design of its "Lifestyle" calculator line mid of the 80s to a slightly smaller form factor and as a consequence the appearance of the next TI-108 generation changed to the design most American elementary students know even today.

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.
