Squawk and Talk Sound Board

I am working on a new design of the old Bally pinball Squawk & Talk sound board (AS-2518-61). My design uses current technology to replicate the function of the old sound board. My goal is to not only replicate the design, but also add additional functionality. My secondary goal is to possibly offer it to others in a final direct replacement printed circuit board. I'd like to see how fast I can get this working. My first trial in the machine was 3 weeks after starting. Currently I am working more on the sound generator design as well as laying out a printed circuit board.

I will be documenting my design journey in my YouTube channel:
