This TI-1796SV looks great - you won't find any right angle in the design. Curious about the SV designation? It is the abbreviation of SuperViewTM which implies the perfect size and contrast of the LC-Display. Compare it with its predecessor TI-1796+.

Dismantling this TI-1796SV manufactured in February 1999 by Kinpo Electronics in China reveals a clean design centered around a Sharp LI31692R single-chip calculator circuit in a conventional Quad Flat Pack (QFP) housing and soldered on a double-sided printed circuit board (PCB). The electronics is powered by 4 small solar cells and a LR54 (LR1130) backup battery.

Inspecting the PCBs of the TI-1796SV calculators brought our attention to two small marks reading 796T-10-2. We spotted a very similar PCB-Mark already with a TI-5018SV and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.

Don't miss the TI-1795SV and its twin TI-7350SV with only 8 digits display in an identical housing.

A similar shaped housing was used with the -1796 introduced in the same year. Don't miss the rare prototype of the -1796.
