Very similar to the TI-1105 but sports an additional [+/-] key. Well known company Addison-Wesley sold it under their own label. The design traces back to the TI-1100-II introduced already in 1985.

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.

Joe Taylor donated a picture of the storage caddy:

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.

Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the Basic.
