Prinztronic Videosport Electronic TV Game 800 - Sound issue
Hi All

I have the above unit based on the AY-3-8500 chip sometimes it works fine but alot for the time it makes the bounce sound when the ball is not hitting the wall or bat when it does that pressing the reset doesn't help.

Would that be an issue with the AY chip? Looking at the circuit it appears the sound comes straight from the AY chip via a transitor to the speaker I have tested the transitor and it is OK.

Brian ...
