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 in February 1984 by Inventec Corporation in Taiwan reveals a clean design centered around a Toshiba T6717AS single-chip calculator circuit soldered on a single-sided printed circuit board (PCB) and powered by a LR43 battery. Please notice that the original design of the TI-1100 II used a single-sided PCB too, while later designs switched to a double-sided PCB.
Not only the calculator brain was developed by Toshiba, the roots of the TI-1100 itself trace back to the Toshiba HB-102.
Inspecting the PCB of this TI-1100 calculator brought our attention to a small mark reading I1100-01H and we started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Compare some other TI calculators with their siblings manufactured by Toshiba.
