We located this purple TI-30X IIS in August 2010 on eBay and noticed immediately the different colored [2nd] key and the associated functions from the original purple TI-30X IIS calculator introduced by retailer Wal-Mart for the Back-to-School 2004 campaign.

Disassembling this model of the TI-30X IIS manufactured February 2007 by Nam Tai Electonics, 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.
