Other things of note from the early days...
No listing of the amount of answers to find down the left side of the board.
The wrong answer 'X's taking up most of the right hand side of the board.
Padding after the first contestant gave the answers in Big Money. Quite obvious it was stalling for time whilst the board operator manually entered the given answers.
The clock counting up from 00 to 15/20 during the Big Money round.
Bob shouting every answer..a lot.
