The 'Spinning Gold Disc' was a particular highlight, where segments of a Compact Disc - a new concept in those days - were removed to reveal a pop star. 'Word of Mouth' was a Hangman game played on the BBC micro where you had to guess a country by revealing certain letters.
But the undisputed thing which sticks in the minds the most were the computer games rounds. Paperboy (now there's a classic), the vault and 110m hurdles rounds (taken from a Track and Field arcade machine behind the scenes) were amongst the games used.
The whole series took the form of a straight knockout tournament. The star prize for the whole series was a BBC micro for your school (!), as well as the honour (and, no doubt, obligation) to play a special extra show against some of the cast of Grange Hill, EastEnders or Blue Peter.
