Fidelity Chess Challenger 7 (CC7)
This was the first time a dedicated chess computer became a success,
selling around 600,000 units. It seems it was so successful
that it even caused Fidelity to make major changes in its production
factory. They moved from Chicago,IL to Miami, FL in the 1980's.
The program was a tweaked version of the same code used in the CC10.
The seven (7) levels have the following response time according to the
manual:
| Level |
Average Response Time |
| 1=intermediate | 5 seconds |
| 2=experienced | 15 seconds |
| 3=advanced | 1:20 minutes |
| 4=mate in 2 | 20 minutes |
| 5=postal chess | 24 hours |
| 6=excellent | 6 minutes |
| 7=tournament | 3 minutes |
