We have lots of AY3-8910 chips on various boards at work (Amusement Arcade) and I want to use one in a helicopter ride (for kids), you know up down, coin in, that sort of thing. Running the whole show from a 16F84 but would like some sound. So does anyone have a datasheet for the above or any other good sound chips. Would like one that could record sounds and play back, pilots talking and the like (that reminds me must get some helicopter sounds on tape). Can't find anything. One more thing the AY3-8910 is made by Microchip but there's nothing on there web page (::scratches head and wonders why::). Thx Karl.
