A cham-cham computer is a new electronic machine that is sensitive to ultrasonic harmonics and micro-tones, seen in The Cham-Cham.

In his chalet on a Swiss mountain, Olsen uses this machine to receive and send coded messages, which is then transformed into music played by the Cass Carnaby Five at the Paradise Peaks Hotel.

The music is then broadcast live on Radio Maxwell to an enemy airbase, where the attack fighters receive their coded instructions to enable them to shoot down the RTL-2 flights.

How it WorksEdit

The message is received in ultrasonic harmonics and micro-tunes, the computer then deciphers the message and turns it into English.
