I found the fold up insert that came in the AutoCAD Release 14 box for tablet overlay. This is a real blast from the past. The overlay sat over top of the Digitizer tablet. The buttons could be programmed to make drawing faster. To bad AutoCAD and the computers at the time were so slow.
Life is easier using 2011. No Tablets. Now if I can find my old 24+ button puck around here somewhere?
