Introduction
The
TI-81, TI's first
graphing calculator, was designed for
algebra and
precalculus. It has since been replaced by newer models which have
faster processors(What a difference 4MHz can make!), more
memory(hundreds of times), and popular features such as
linking capability and
flash upgradability. The
TI-81 drew little in the way of
third-party games and other
programs, since the code must be
typed into the
calculator by hand and could not be 'traded'. Note: Some of this came from www.ticalc.org
