The second generation TI-108 looks completely different to its predecessor, please focus on the position of the solar cells and the size of the display frame. Actually the calculator is around 0.2" (6 mm) smaller. We know a very similiar calculator with the TI-1105.

Dismantling this TI-108 manufactured in August 1988 by Inventec Corporation in Taiwan reveals a pretty simple internal constuction.

Since 1992 the TI-108 is using smaller solar cells but the design changes are barely noticable. Please find a detailed overview of the different hardware versions of the TI-108 calculators between 1988 and 2001 here.
