This TI-1105 introduced in 1991 is completely different to the original TI-1105 sold 5 years earlier. The solar cells were replaced by a small battery and instead a colorful design only a white or grey housing was available.
Dismantling the TI-1105 is a funny experience, the technology is identical with the Canon LC-25H. Both calculators sport the letter "N" in the Date code, a hint of the manufacturer Nam Tai Electronics, Inc. in China.
We knew the printed circuit board (PCB) already from the identical TI-1100+.
The TI-1105 was available in a grey housing, too.
