Very similar to the TI-1104 but uses solar cells instead the batteries. The second generation of the TI-1105, the TI-1106 and later the TI-108 added the [+/-] key to the functions found on this early TI-1105.

Three different colors were introduced:

TI-1105 Turquoise
TI-1105 Magenta
TI-1105 Dark blue

The successor of this colorful calculator was introduced in 1991 with a rather disappointing design, don't miss the new TI-1105.

Note: The TI-1105 featured in the CL-922A brochure sports an [AC] and [+/-] key!
