This
blue colored
TI-30X IIS was manufactured exclusively for the retailer Target. It was released for the
Back-to-School 2021 campaign together
with its pink sibling and the TI-84 Plus Silver
Edition in the colors of blue, white and red.
Disassembling
this model of the TI-30X IIS manufactured May 2020 by Kinpo Electronics, Inc. in the
Philippines reveals a well known internal
construction centered around an unknown single-chip calculator circuit and
powered by four small solar cells and a CR2025 backup battery. We discovered already in 2004 with Inventec
Shanghai, Kinpo Electronics,
Inc. and Nam
Tai Electronics, Inc. three different contract manufacturers for the TI-30X
IIS. Comparing two calculators with Date codes K-0304 and K-0409 yields no
significant differences.
Inspecting the PCB of this TI-30X IIS calculator brought our attention to two small marks reading
SR16N/N1-11 and SR16/SR16B-23, we noticed similar marks already with other
Slide Rule calculators manufactured by Kinpo
Electronics and started compiling a list of the
PCB-Marks on calculators
manufactured by OEMs for Texas Instruments.
This design was used in Summer
2011 by four retailers: Target,
Fred Meyer,
Meijer and
Shopko. In Summer 2012
Office Max added the design
to its selection.
In Summer 2021 three other retailers used the "Lightning
Blue" design but their box used a different Universal Product Code (UPC): Meijer, Office
Depot and Staples (in alphabetical order).
