The TI-1100 II got an enhanced display compared to the original TI-1100 II introduced one year earlier.

ti-1100-II_PCB.jpg (58919 Byte)The inside view of the TI-1100 II gives you a simple but reliable design. The Toshiba T6958S calculator-chip scans the 24 keys and drives the LCD. The whole electronics is powered by a simple 1.5V coin type battery. The housing consists of only two parts which could be found even 8 years later with the TI-108 calculator.

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. View the later TI-1100 II. Recently we spotted a TI-1100 II manufactured late in Taiwan late in 1989.
