Andy (Beaky) is working on a 1985 Gottlieb machine called "Rock" (IPDB link below)
A schematic for the sound board is required. The part number on the sound board is "24548 sound board".
Wondering if u know of a place where Andy might find a schematic for it ? We can purchase the full manual from Marco Spec, but would prefer is someone had a copy of the sound board schematic on file ?
Any advice would be appreciated.
regards Brett for Andy
