Fidelity Chess Challenger (CC1)
Fidelity CC1  1  35 x 35

The Fidelity Chess Challenger, often referred to as the CC1, was the first chess computer sold to the public. The story of how that came about can be found here (link). Fidelity won the race to get a chess computer on the market but they made it with a bungled product. The playing notation on the board was reversed, with files labelled 1 to 8 and ranks labelled A to H. The computer used this notation to accept and output moves. So a popular opening move e2-e4 would appear as 5b-5d.

Although moves eg Ng1-f3 require the same keys to be pressed as on a normal keypad, accepting and keying in moves in this reverse notation can be a slow and confusing process. A mistake ruins the game as there is no going back once the move is entered. The other main shortcomings of the Chess Challenger were the extremely poor standard of play and that it accepted illegal moves.

Fidelity knew that criticism was coming and the documentation with the CC1 offered an upgrade (see documents below). The upgrade involved sending the CC1 back to the factory where a new three level chess program ROM was substituted and the entire chessboard / keypad surface membrane was peeled off and replaced with one having the correct notation.                       cont >

Playing a game with a CC1. Patience and concentration is needed to key in the moves in reverse notation. I start with 5b-5d. CC1 replies 5g-5e. White Knight 7a-6c. Black Knight 2h-3f. Then I send out a tempter 4b-4d. CC1 4g-4f. I start to go for the kill. Really!  Knight 6c-7e. CC1 accepts the pawn present Knight 3f-4d. And the killer blow Queen 4a-6g. CC1 signals that it is Checkmated with the I Lose light.

It is chess, but not as we know it. Chess Sid Samole and Ron Nelson style from Spring 1977.

How many CC1s survive today?

1000 CC1s were built according to Sid and Shane Samole.

Although quite a few chess computer enthusiasts have one (see Serial Number list below) I would still describe the CC1 as a rare chess computer. The flawed implementation and hardware faults resulted in many Chess Challengers being returned to retailers. In todays language the CC1 was not fit for purpose. You get the picture from the first paragraph of this Computer Chess Digest 1984 article by Steven Schwartz “Pity The Poor Chess Computer Buyer” (link). Retailers would have returned rejected and unsold stock to Fidelity, who in turn would have upgraded it. The offer to upgrade at a cost of another $75 must have been received as a dubious privilege by many individual customers, and I cannot envisage that a high percentage of them took advantage of it.

The evidence of upgraded CC1s is seen in the Chess Challenger boxes with the red “Three Levels of Play” sticker (see above). I have one such CC3 and have seen plenty of others on the internet, including several on Ebay. I also know of one CC1 which was upgraded to a CC3, and that in turn was upgraded to a CC10C. Of course most of the boxes with the red sticker would not have survived three decades so there will be many times more upgraded Chess Challengers than there are red stickers. Nevertheless the upgraded Chess Challenger could be almost as rare (though not as valuable) as the original.

Let us assume that one third of CC1s were returned by retailers and 10% of sold machines were upgraded. That leaves us with 600 CC1s. I know that Steffen Scholz has been told by an ex-Fidelity employee that 75% of CC1s were upgraded, leaving only 250. Let us assume for now that the non-upgraded number lies in the range of 250 to 600.

What happened to these? Some would soon have been thrown away as a purchasing mistake best disposed of. However a large majority would probably have gone into storage in American closets, attics and basements. A useless, but interesting and expensive piece of junk. These CC1s would have had to survive three decades of storage to still be around today. House moves and clear outs in the 1980s and 1990s will surely have led to many casualties. Hardware faults such as the tendency for LED display segments to disappear will have increased the casualty list. As time went on the CC1s will have been seen more as worthless junk than interesting. That is until the revival of interest in dedicated chess computers in recent years. My estimate of the ones that have made it to 2008 in working condition is one half, that is 125 to 300.

The advent of Ebay has made a great difference to those interested in collecting. In the last three years there has been a steady flow of CC1s appearing on Ebay USA. I have taken an interest in these sales for five years and have records of 28 genuine CC1 Ebay sales. One would normally expect only a small percentage of a chess computer model to appear on Ebay, but the CC1 is a special case. Prices up to £800  have been obtained, though £300-400 was the average until a recent fall in prices. So the CC1 is an item with very little utility but plenty of rarity value, the type of item which most encourages individuals to sell on Ebay. I expect the current 5-10 Ebay sales a year to continue for a while (written in 2008).

Many chess computer enthusiasts with a collection want a CC1. It is an historic model. Lengthy posts about Fidelity manufacturing and serial numbers on Kurt Kispert’s Forum by Karsten Bauermeister and Steffen Scholz, which included a list of 14 CC1 owners, led me to maintain a running list. From time to time it has been posted on Ismenio Sousa’s Message Board. This is the updated list (February 2017) with the serial numbers and last known owner of each CC1 :-
