Production
of the TI-508 and its twin TI-1795
was shifted in 1991 from Taiwan to Thailand. The leading "C" in the Date
code reveals Cal-Comp
Electronics as manufacturer of these small dektop calculators.
Dismantling
this TI-508 manufactured in July 1992 reveals no surprises, the printed circuit
board (PCB) is centered around a Sharp LI3135MR single-chip calculator circuit
known already from the TI-502.
Within a few month the TI-508 PLUS replaced the TI-508.
