Go up one level in this thread

Here some more comments by me:

The Chess Challenger 7 was the fourth computer ever made by Fidelity
Electronics: After the first one (today called Chess Challenger 1),
Challenger 3 and Challenger 10A and 10B. Each was named by his number of
levels, so the CC7 has seven levels. It came out in the middle of 1979.
The CC7 was the first chess computer of Fidelity, that has no wodden
housing, it was fully made of plastic. There were at least two
(slightly) different versions. One with a shining surface, and one
version with rough surface. Also there were some minor differences in
the programs.
The CC7 played a little bit more agreesive than the CC10 and knewed the
same openings (about 80 plys!).

By the way: Ron Nelson, the programmer of the CC7, wasn't "replaced" by
the spracklens, but he was responsible for hardware and some minor chess
computers further on (Chess Challenger Sensory Mini I + II in 1981/82).
Today he is busy at Excalibur Electronics, which are stil producing
chess computers. Who is interested in them can take a look at
