The Novag Robot Adversary TM is the most iconic of chess computers. There are several reasons.
Firstly, for a product of 1982, its startling futuristic appearance.
Secondly the robot arm which in terms of robotic character, comparative speed and range of movement is extraordinary for a consumer product.
Thirdly the variety of functions - including autoplay, automatic setting up of the pieces for a new game, trace and review, best move, sound, lights, printer support, and not forgetting the tantrums produced by the ‘emotions’ button which involve waving of the arm, flashing lights and noisy sound. These functions all contribute towards a very impressive and entertaining machine, which was outstanding when it was first sold, and has not been bettered since.
