"Mystic_lgc" was splitted into three files fitting into a standard Bally board, jumpered to accept 3x 2716 EPROMs.
The game code is very close to the one used on Bally's 1979 "Star Trek".
If there was no special Zaccaria sound board (nobody seems to know), the sound board from Star Trek should work here as well, so the matching PROM is included.
