TI-108 was introduced already in 1986 and we are
positive that the internal construction was changed from time to time. The featured
calculator was manufactured in March 2000 by contract manufacturer Nam
Tai Electronics, Inc. in China.
Dismantling this TI-108 reveals a typical design of a calculator developed in the 1990s. The single-chip calculator circuit is bonded directly to a high-quality printed circuit board (PCB) while the keyboard makes use of a much simpler Phenolic PCB. We know a similiar design e.g. with the TI-15 Explorer.
