Mac and PC

For Windows, it's been successfully run on Windows XP, Vista and Windows 7. We've also had user run RoastLogger on tablet PCs without any issues.
Communication between RoastLogger and the data bridge occurs via USB (Universal Serial Bus). As such, be sure that your computer/laptop has an available USB port.

The application is not resource intensive, so you don't need a powerful graphics card or any other type of special hardware.
