"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.
