You can install and use SIMON on any Macintosh (OSX) or Windows (Windows95 or later) computer. All you will need is enough disk space to store the RCM teacher files (at the end of the school year, teacher files will be about 150KB - 300KB per teacher), and a minimum of 64MB of RAM.

When you open SIMON, you will see the Main Screen. The Main Screen allows you to choose what you want to do: Edit Data, Import Data, Export Data, or get Statistics.
