System 9 sound and speech boards fit System 6/7
System 9 sound and speech boards (as on Space Shuttle, Sorcerer and Comet) are practically the same design and work in System 6/7 games. The System 9 speech board can be jumpered for 2532 or 2732 EPROMs, which the System 6/7 one cannot easily do. Board numbers: C-8224 sound board (System 6/7 and 9), C-8228 System 6/7 speech board, C-10716 System 9 speech board.
