TI-7 MathMate was introduced already in 1993 and
looks even in 2009 familiar. This second generation of the TI-7 MathMate looks identical to
the original design but added a small battery to
the solar cells.

Dismantling a TI-7 MathMate assembled in October 2004 by Nam Tai Electronics, Inc. in China demonstrates a clean internal construction but the calculator circuit doesn't reveal its genes. Please notice the already mentioned CR1220 lithium battery next to the solar cells.
Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the Elementary.
