Hi,

The "Fidelity Voice Sensory Chess Challenger" (Model VSC) cannot be easily compared, because it has a sensory board and more ROM. That extra ROM is presumably for the control of the sensory board, but there are other differences such as the 64 Greatest Games stored. I don't know what similarities it has in terms of engine, opening book, etc.

Regarding the speech language... Indeed, the Decorator brochure says that. I also read somewhere that the Grandmaster was intended for the German market (speech in German only?), but I don't have any more information.

In my case... the Decorator I repaired had the speech in English, and the Grandmaster in German. :-)

Best,
Gerardo
