Hi again, To expand on my previous message, I'm hoping that the BrailleConnect 12 display can be used with the Mac, or some other portable display of 20 cells or less. I just looked at a page detailing various supported devices, but I'm not sure whether this resource is up-to-date. Here is the link: http://www.apple.com/accessibility/voiceover/devicesupport.html Thanks again everyone, Scott
