Notes::

This unit has 16 registers more than the 10B.  Memory is structured
into separate statistics and independent (including financial)
registers.  There is no "clear fin" function, so financial registers
must be cleared manually or all memory cleared.  (Jordi Hidalgo, Datafile
V20N2p5)

This unit has an ON key.  They key does nothing once the calculator
has been turned on.

There was a color scheme change in 2008.  It now has orange and blue
shift keys.
