Just a redesign of the original TI-30X IIS introduced already in 1999. 

TI-30X_IIS_1.jpg (82857 Byte)Please compare both calculators and notice the changes:

Aluminum bezel around the display to match with the 
   basic TI-1706SV, the graphing TI-84 Plus and the 
   financial BA II PLUS Professional.
More prominent nameplate like the TI-30XA.
Key colors changed to a serious blue in blue like the TI-82 STATS

To discover the real changes between the first and second series of the TI-30X IIS we dismantled them and found two different printed circuit boards (PCB):

This early TI-30X IIS with the leading SR-16 designation was manufactured by Kinpo Electronics, Inc., a famous company located in Taiwan and doing calculator production for well established companies like Texas Instruments, Hewlett Packard, Casio, Canon and Citizen.  TI-30X_IIS_PCB.jpg (61493 Byte)
This redesigned TI-30X IIS makes use of a totally different printed circuit board (PCB) manufactured by Inventec Shanghai. TI-30X_IIS_2004_PCB.jpg (74864 Byte)

The backside of the redesigned calculator reveals another enhancement - a small Reset key could be pushed with the tip of a paper clip. 

From much higher interest is the position of the Reset key - it differs between models purchased in Canada and another one from the German market. Find more details about the TI-30X IIS manufactured by Nam Tai Electronics, Inc..
Recently we discovered the latest model of the TI-30X IIS in a wonderful purple case manufactured by Kinpo Electronics, Inc. - get some pictures here. More colors were available in 2007 from the retailer Target and the office products supplier Office Depot. Don't miss the lime-green TI-30X IIS and the pink TI-30X IIS.

Don't miss the redesigned TI-30X IIB, TI-34 II, TI-36X II, TI-40 Collège II, and BA II PLUS.

Texas Instruments complemented both the TI-30X IIB and TI-30X IIS with the next generation scientific calculators TI-30XB MultiView resp. TI-30XS MultiView in 2007. The successor of the TI-34 II was announced May 9, 2007, too but the TI-34 MultiView didn't hit the stores together with its sibblings.

Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the wonderful TI-30X II Overhead Calculator.
