New redesigned squawk and talk sound card, I picked up when I had an old Bally pin. I bought it as a kit, tested it in the game and ended up selling the game shortly after. This is the same board designed by Jim Askey/mypinballs/applejuice here in the forums.
The summary of updates for this board are:

- Reduced component count
- Test point pads for common signals and voltages
- Leds for power voltages and diagnostic led
- Improved and simplified reset section
- On board reset button
- Dip switch config for rom settings
- Fully compatible with all stock roms
- Dip switch config for inclusion of sound generator ic
- Expanded J2 connector to allow future plug on daughter cards such as echo/reverb board.
- Option via J2 for external amp hook up and multiple speaker usage
- Higher power amp on board for stock speaker connection
- Socketed ICs
- Plate through design
