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 calculator reveals a standard design using a single-chip calculator circuit wire-bonded direct on the printed circuit board (PCB).
We knew the printed circuit board (PCB) already from the identical TI-1100+.
Don't miss the TI-1105 in a white housing.
