Please read more about the Logarithm Bug and its side effect on the related yx function present in the early models of these calculators.
The featured calculator was manufactured in August 2002 by
contract manufacturer Kinpo
Electronics, Inc. in China and should be "bug free".
Dismantling the TI-30X IIB reveals a typical Kinpo design of a calculator developed in 1999: The Kinpo-internal SR-xx designation on the main printed circuit board (PCB) and a Fibreglass PCB for the keyboard instead the cheaper Phenolic PCB used by competitor Nam Tai Electronics, Inc.
In 2004 Texas Instruments introduced a new design line with a really prominent name plate and some modern applications like an aluminium bezel around the display. Please start your journey with the new TI-30X IIS.
