It requires the Qt widget set. Send questions about Dboard to Christoph, not me. The Dboard page is available in English or German . Luc Porchon has written a driver that makes a Novag Universal Chess Board look like a WinBoard chess engine. This is perhaps not the ideal way for the UCB to interface to WinBoard, because WinBoard thinks you are a chess engine, not a person, but you might find it useful anyway.
Source code is included.
I have not tried this driver, since I don't have a UCB, so don't send me questions about it. Nicolas Cominetti has written a similar driver that makes a Saitek Kasparov PC Autoboard look like a WinBoard chess engine. Please see the documentation included in the file or ask Nicolas if you have questions. I don't have this chessboard and have not tried the driver. There is also a way to use a DGT Electronic Chessboard with WinBoard.
