Instruments introduced already in 1990 with the original TI-1775
a calculator using a foldable housing. The TI-1775+ added a simple clock to the
basic calculator functionality and matches the styling
of the TI-307+ and TI-2200+.
Dismantling this TI-1775+ manufactured in January 1997 by Compal Electronics in Thailand reveals a rather simple construction based on a single-chip calculator circuit in chip-on-board (COB) technolgy.
