Infos from Mike Watters -

The Fidelity Little Chesster Challenger is a budget version of the Fidelity Chesster Challenger. Emphasis is on an entertaining chess partner. It is still capable of 345 phrases, but the board, the speaker and the computer hardware are all low budget components. According to Computer Chess Reports 1991 Vol 2 No 1 Page 5 the program is the same as the later models of the Fidelity Excellence but on slower Hardware, with a much smaller opening book which allows it to be contained on the 4KB ROM. It includes a genuine novice level suitable for beginners.

The main circuit board components are :-

M50743SP - Single Chip cpu with 6502 architecture, 128 KB ROM and 256 bytes RAM


and the voice synthesizer chip.

In fact two versions of the Little Chesster were manufactured. In the photograph showing both versions (below), the one on the right is the original version made in 1991, and the one on the left dates from 1992. The original had 8 countdown levels which are not found in the later model. The two versions also have different piece sets. You may also come across some 'clones' of the 25 level version, namely the RadioShack 1900L Talking Chess Computer and Sharper Image Talking Chess Companion.
