INTRODUCTION: Ohm is a simple resistor color code conversion application
              used to calculate resistor values from 4-band color codes
              and vice versa. The application is written for students
              and engineers who often use resistors in design, but cannot
              always remember the proper color code.

USAGE: Ohm is very straight forward to use and requires only a few pen taps
       to arrive at an answer. Upon start-up, you will see the following:

       "Color -> Value" button: This button is used to toggle between color
                                code-to-value conversions and value-to-color
                                code conversions. Clicking on this button
                                will change modes. The label of the button
                                will change as well, signifying your current
                                conversion mode.

       "Color" pop-up lists: Use these three pop-up lists to select the first
                             three color bands on the resistor whose value
                             you want to calculate.

       "Value" field: This field accepts up to 8 digits (0-9) for a
                      resistor value you would like to convert to a color
                      code.

       "Calculate" button: This button will calculate the results according
                           to your selection of colors or value in the field,
                           depending on the "Color -> Value" button.

COLOR-TO-VALUE CONVERSIONS: Ohm defaults to "Color -> Value" conversions.
                            Simply select the three colors using the
                            "1st Color", "2nd Color", and "3rd Color" pop-up
                            lists and click the "Calculate" button. Your
                            result will appear in the "Value" field. Note
                            the units (ohm, k ohm, m ohm) on the right-hand
                            side.

VALUE-TO-COLOR CONVERSIONS: Tap the "Color -> Value" button so the label
                            changes to "Value -> Color". Enter your required
                            value in the "Value" field and select the units
                            using the pop-up list on the right-hand side.
                            When your value is entered, click the "Calculate"
                            button. The three significant color values will
                            appear above.

OPTIONS: Tapping the "Menu" silk-screen on the PalmPilot will enable a menu.
         You have the following choices:

         "Color Value Display": This toggle will display the corresponding
                                number next to the color during a "Color ->
                                Value" conversion. This feature is helpful
                                for learning the resistor color codes as
                                you go.

         "Quick Reference Guide": This selection will list the resistor color
                                  code for 4-band resistors, including
                                  the tolerance band.

         "About Ohm...": About Ohm... Tapping the "i" on this dialog box will
                         pop-up usage and version information.

RESTRICTIONS: o Ohm will only work with PalmOS >= version 2.0
              o Resistance values can range from 10 ohm to 99 meg ohm.
              o All values are rounded down.

TO DO: o Floating point support (i.e.: 4.7k instead of 4700). Decimal points
         do not work at this time.

DISCLAIMER: The Grand Design takes no responsibility for the results of this
            application. It has been tested to the best of our capabilities
            and is believed to be in working order. Any data lost, erased,

            This program is being released for free to the public, but
            donations, comments, broken electronics, etc. will be graciously
            accepted.
