fifth generation TI-108 looks looks at first
glance very familiar to us and you have to read the small printed on the backside of
the blue housing: 3V X 1 CR1220. Yes, finally a backup
battery for the solar powered TI-108 introduced already in 1988!
Dismantling this TI-108 manufactured in August 2004 by Inventec Corporation in Shanghai (China) reveals a pretty simple internal construction.
Please notice the Sharp LI3154 single-chip calculator circuit in a traditional package - a technology rarely seen in the 21st century.
Texas Instruments changed the design of the TI-108 again in 2016 and the internal backup was switched from a 3V Lithium battery to a more common (and more economical) Alkaline button cell with 1.5V.
Please find a detailed overview of the different hardware versions of the TI-108 calculators between 1988 and 2016 here.
