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 2016 a TI-108 manufactured in August 2008. Please find a detailed overview of the different hardware versions of the TI-108 calculators between 1988 and 2016 here.
