This
stylish small desktop calculator is unique in Texas Instruments' line but
matched the design line of the TI-1768.
In Europe a similar calculator was sold with the TI-608.
Dismantling
this TI-1797 manufactured in June 1986 by Compal
Electronics in Taiwan reveals no surprises. A small single-chip calculator circuit probably
manufactured by Sharp and a long flexible cable to the LC-display. Please notice
that the mold of the housing is prepared for a battery instead of the solar
cells.
