The Kurta tablet was tested with MacDraw II, and therefore will work with Claris CAD. We have found however, that it will not trace accurately, which is what most people want to do. Kurta can be reached at: 602-276-5533
We have also tested the Summagraphics Bit Pad Plus (an ADB tablet plugging into the mouse port) and it seems to work well. It is easy to set up and traces accurately. Summagraphics can be reached at: 203-384-1344.
