TI-1100-II_I1089_Back.jpg (41378 Byte)The production of the TI-1100 II was shifted about 1987 from Taiwan to Malaysia. Nevertheless was this TI-1100 II manufactured in Taiwan late in 1989.

TI-1100-II_I1089_PCB.jpg (179887 Byte)Dismantling this featured TI-1100 II from the 4th design manufactured in October 1989 by Inventec Corporation in Taiwan reveals a clean design centered around an unknown 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 IOTI1100IIIA-01A and we started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.

In 1991 the design was changed dramatically and we got the TI-1100+.
