Setting up a sound board for speech

Games that talk (Alien Poker, Black Knight, Blackout, Firepower, Gorgar, Jungle Lord, Pharaoh) need jumper W1 removed from the sound board and DIP switch 2 ON. Switch 1 only matters with switch 2 off (sound only), where it picks synthesized sounds or musical tones. Check the game manual for the right setting.
