The TI-1100 II received an enhanced display compared to the original TI-1100 II introduced one year earlier.
Dismantling this featured TI-1100 II from the 2nd design manufactured in November 1986 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.
A more stylish variant of this housing could be found with the TI-1103 and TI-1104 calculators. Even the TI-1105 and the later TI-108 make use of the molds.
Some years later, around 1987, the production of the TI-1100 II was shifted to Malaysia. Don't miss the 3rd design of the TI-1100 II. Recently we spotted a TI-1100 II manufactured late in Taiwan late in 1989.
