I have a client who still uses R14 because he says he can't use his tablets (CalComp Drawing Board II and SummaGraphics II) with any version of AutoCAD later than R14. I have found drivers for them from GTCO Calcomp, but no direct information about using them from AutoDesk. Does AutoDesk have drivers for these tablets, or must he get newer tablets, or do later versions of AutoCAD just not talk to tablets anymore?
