The TI-1100 is very similar to the TI-1706 but uses a single battery instead the solar cells. The design was unique and replaced soon with the TI-1100 II.

Dismantling this TI-1100 manufactured early in 1984 by Inventec Corporation in Taiwan reveals a clean design centered around a Toshiba T6717AS single-chip calculator circuit.

Not only the calculator brain was developed by Toshiba, the roots of the TI-1100 itself trace back to the Toshiba HB-102.

Compare some other TI calculators with their sibblings manufactured by Toshiba.
