Hello Peter,

You are right. I have been looking at the VCC and UVC ("Fidelity Chess Challenger Voice" and "Fidelity Advanced Voice Chess Challenger" respectively) manuals and they both list this repertoire of 46 book opening variations, selectable with squares A1 to E8 (40), and in addition with F1 to F6 (6).

But if this was already true for the VCC and UVC models, the "Decorator" and "Grandmaster" models brought nothing new, and therefore the "Gegenüber dem sonst identischen Schachprogramm im Fidelity Chess Challenger Voice Advanced wurden 46 vorprogrammierten Meisterpartien von Morphy bis Karpov hinzugefügt und die Eröffnungsbibliothek erweitert" sentence is not correct. Right?

Best,
Gerardo

Yes, nothing new in the Decorator/Grandmaster.

Die Fidelity Geräte Chess Challenger Voice Advanced, Decorator Challenger und Chess Challenger Grandmaster Voice sind also alle programmgleich - gilt das auch für den Chess Challenger Sensory Voice ?

In einem Fidelity-Prospekt von 1981 zum Decorator heißt es: "Available in English, German, French and Spanish language."
War der Decorator wirklich polyglott - oder sprach er doch nur englisch ?

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

Both Grandmaster and Decorator should be identical with the Fidelity Advanced Voice Chess Challenger.

Grandmaster Voice was produced in Germany due to the high US-Dollar at the time being, with handmade inlays for each chess field.
Decorator is the US version with printed chess fields and feet below the board. The largest chess computer ever built.

Thank you.

As far as I have been able to verify, this is the case, but of course my "sampling" is small: I have repaired several UVC, but only one Grandmaster and one Decorator!
That is why I had my doubts.

hap has already documented all this in MAME, and now it remains to correct the Schachcomputer Wiki files so that there is no confusion.

Best,
Gerardo

Hi,

Well, I've tried to reflect what has been said here in the Wiki files:

Fidelity Chess Challenger Grandmaster Voice (1980): link
Fidelity Decorator Challenger (1981): link

Thank you very much, Gerardo!
