TI-1100 II received an enhanced keyboard compared to the original TI-1100 introduced
two years earlier, please study the sales box of a TI-1100 II sold in 1985 in
the United States. Another few years later a similar calculator appeared again
Dismantling this featured TI-1100 II from the 1st design manufactured in March 1985 by Inventec Corporation in Taiwan reveals a clean design centered around a Toshiba T6985S single-chip calculator soldered on a double-sided printed circuit board (PCB) and powered by a LR43 battery.
Inspecting the PCB of this TI-1100 II calculator brought our attention to a small mark reading IOOTI1100-02D and we started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Within one year the display size of the calculator was slightly increased, please notice the width of the display frame of the 2nd design of the TI-1100 II.
