League Champ © 1996 Williams Electronics Games, Incorporated.
BOARD SET: WPC 89 CPU, modified sound board, WPC89 driver board.
SOUND: It uses only a DAC for digital sound effects and test menu sounds and a 55536 CVSD speech chip, most commonly used in early speech expansion boards of the System 3-9 games. Originally they use the Yahama chip set for many pinball games but not in these bowler games.
