This
"Radical Red" colored TI-30X IIS was manufactured by Kinpo Electronics,
Inc. for the office product retailer
Office Depot /
Office Max. It was released for the
Back-to-School 2020 campaign together
with its pink and
blue siblings and the TI-84 Plus CE in the colors
Galaxy Gray and Rose Curve Gold.
Disassembling
this model of the TI-30X IIS manufactured April 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.
In Summer 2020 four retailers used the design: Amazon, meijer and Office Depot / Office Max (in alphabetical order).
Don't miss the TI-30X IIS OGT
introduced in Summer 2008.
