- Over 200 equations, a steam table generator, a thermocouple
converter, reference data, and a constants library are included on the 128k card.
- Easy entry of values for variables (with units) using the
menu keys provided. Easy solving and converting of units.
- Menu can be displayed in a large or small font size.

The user interface browser presents three broad categories:
an equation library in 8 categories; analytical functions consisting of a steam table
generator, a thermocouple calculator, and numeric vector analysis calculations; and a
constants library along with a reference short library.

Equation sets in a given sub-topic can be solved as a
complete or selected set. The variables in the equation sets have descriptions in addition
to names.

The equation solver comes with a handy units menu,
rendering the task of unit entry effortless. The computed results can have their units
converted into SI or into another chosen set of commonly used units. An equation can be
selected to plot, and a multiple plot function can be used to do graphical analysis,
viewing the impact of incremental changes to a variable.
