Is this TI-1795+ a small desktop calculator or a large handheld calculator? The type designator suggests the "Desktop Category" of the Datamath Calculator Museum, from the size it could easily a "Handheld" like the TI-508 PLUS.
Beside the smooth styling the calculator itself is very plain and looks still like the first TI-1795 introduced already in 1984.
this TI-1795+ manufactured in March 1994 by
Electronics in Thailand reveals a very simple construction centered
around a Sharp LI3154 single-chip calculator circuit soldered on a double-sided
printed circuit board (PCB) and powered by solar cells. We noticed this chip during our research about
so-called Checkbook Calculators with the Radio Shack

Inspecting the PCB of this TI-1795+ calculator brought our attention to a small mark reading SD9L1-10-1, most likely a reference to Type Small Desktop 9. We spotted a very similar PCB-Mark already with the Radio Shack EC-2006A and Privileg SOLAR 31 and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Within four years the design of the TI-1795+ was changed slightly and an interesting journey around the globe began. Don't miss:

Kinpo Electronics (Taiwan),
• TI-1795+ Second Generation Cal-Comp Electronics (Thailand), October 1995 and April 1998
• TI-1795+ Second Generation Nam Tai Electronics (China), May 1998

In 2000 the TI-1795+ was finally replaced with the stylish TI-1795SV (SuperViewTM).
