How would I know this? Because a chicken restaurant we frequent has
one, and it's still in use! Kids put in a quarter and get a toy in a
plastic egg. Worst rendition of a chicken I've ever heard - sounds
like someone's first day playing with their new synthesizer.



That board looks way too simple to be the sound generator, I would
expect there to be another board for that, it's been probably 2 decades
since I've used one of those machines but I do remember them from when I
was a little kid.
