This TI-1795SV introduced in Summer 2003 together with the TI-503SV and TI-1706SV a rather bold design style for electronic calculators. Compared with the first generation of the TI-1795SV its successor added tax functionality and uses a stylish coloring scheme with a mixture of white, silver and black elements, continued in 2004 with the TI-36X SOLAR, TI-84 PLUS Silver Edition, TI-89 Titanium and to some extend the BA II PLUS Professional.
The TI-1795SV traces back to the legendary TI-1795 introduced in 1984 also known as OEM Design SD9 and probably the best selling Small Desktop calculator of all time. The blister boxes of the TI-1795SV stated in 2003, depending of the region of sales, accordingly "Millions sold" or "Still the classic mini-desktop calculator for home, office, or retail with big keys and extra-large display". As of April 2020 the TI-1795SV is still without major changes on the market and we know 5 different versions:
• TI-1795SV K-0403D (2003) internal battery, Kinpo Electronics China, April 2003, Rev. D
• TI-1795SV N-1205D (2003) internal battery, Nam Tai Electronics China, December 2005, Rev. D
• TI-1795SV K-1007F (2006) with battery door, Kinpo Electronics China, October 2007, Rev. F
• TI-1795SV N-0208F (2006) with battery door, Nam Tai Electronics China, February 2008, Rev. F
• TI-1795SV L-0217K (2006) with battery door, Kinpo Electronics Philippines, February 2017, Rev. K
This 2nd Generation of the TI-1795SV feels much more substantial than
its predecessor, it actually gained about 30% weight by using much thicker
plastic material for the two parts of the housing and added a robust protection
window to the LC-Display. Dismantling this TI-1795SV manufactured in April 2003
by Kinpo Electronics in China
reveals a pretty clean design centered around an unknown single-chip calculator
circuit mounted in Chip-on-Board (COB) technology directly onto a double-sided printed
circuit board (PCB) and powered by 4 small solar cells and a LR54 (LR1130)
Inspecting the PCB of this TI-1795SV calculator brought our attention to a small mark reading 795S-10-2. We spotted a very similar PCB-Mark already with the TI-1796SV and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
In 2006 Texas Instruments upgraded the TI-1795SV and added a removable cover for much easier access to the internal battery of the calculator.
