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.
