It was quite a surprise when we learned in July 2017 from Michael MacEachern that he just acquired a TI-108 manufactured in March 2017. He noticed some interesting differences compared to the four TI-108 versions we had as of July 2017 exhibited in the Datamath Calculator Museum:
Missing gray bezel for the display frame.
• Larger numbers on the LC Display.
• Internal backup battery.
• TI logo printed in white.
Trying to fill the voids we screened many ebay Auctions in the following months and discovered in addition to this design introduced in or around 2014, a TI-108 manufactured in August 2008 and a TI-108 manufactured in July 2014. Please find a detailed overview of the different hardware versions of the TI-108 calculators between 1988 and 2016 here.

the Philippines reveals a pretty simple internal construction from the Nineties
that is identical with the earlier design manufactured in China.
The unknown single-chip calculator circuit of this TI-108 is hidden under a small epoxy blob.
