It was a pleasant surprise for the Datamath Calculator Museum when in June 2009 this red colored
TI-30X IIS appeared on the US eBay auction
site and we were able to acquire the unit.
Knowing inside out all the colorful TI-30XII variations introduced since 2003 by various US retailers, for instance Wal-Mart, Target, Office Depot and Staples, we asked immediately a question: "Fellow collectors - if you know the retailer behind this wonderful red TI-30X IIS - please drop me a line. Thanks!"
It took another month before we could solve the mystery - a second red-colored TI-30X IIS appeared on eBay and both auctions had something in common: The sellers lived in Ohio.
What is the red TI-30XIISR?
Texas Instruments has produced a red TI-30X IIS specifically for the state of Ohio to use for their Ohio Graduation Tests (OGT). The schools refer to it as the TI-30XIISR.
There is also a red unit available for Ohio schools that does not have the OGT logo. These are available through Copco, an instructional product dealer.

Disassembling this model of the TI-30X IIS manufactured June 2008 by Kinpo Electronics, Inc. reveals a well known internal construction. 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 datecodes K-0304 and K-0608 yields no significant differences.
In the meantime - after about two years - our second question "Fellow collectors - if you own a red TI-30X IIS with the OGT logo - please drop me a line. Thanks!" was answered by Mark Bolmann. Thanks! Get a picture here.
The Ohio Department of Education released in October 2008 newsletter "The Ides of ODE" a nice (high-lighted in blue) statement:
|New OGT Calculators
The fall administration of the Ohio Graduation Test will begin on October 27, 2008. By now all school districts should have received their fall shipment of the new OGT Calculators. The new TI-30XIISR is the only calculator to be used on the OGT. The unique red color is to assist proctors in identifying the approved calculator.
The new calculators are believed to be more durable than their predecessor.

For sure did we research the “predecessor of the new OGT calculator” and found the Senario Model SC-121, a rebranded Karce KC-121.
