When I was younger I remember some folks having those fancy TI calculators,
and I also remember the "manual" was a pretty large one... in my memory, it
was at least as thick as the calculator.  ;)

They could do some pretty neat things with them.  Later, I remember they
got a little more high tech and could even display graphs.  This would have
been back in the 1980s.  I wonder now how their computing power compares to
that of a cell phone or a PC.
