Hello all,
I was just throwing this out to hopefully find an answer. I have a Pong c-100 that I found at my mom and dads this weekend that I used to play when I was a kid. Anyhow, It will display the game, play sound, but it starts on its own and will not keep score. I have it taken apart, and found that it has the 3659-3 IC in it. It also has a 7404-n Hex inverter in it. My question is, does anyone know what could be causing the issues with the score and self starting or if anyone has the pin outs for the 3659-3 IC? Any help would be appreciated. I tested the start switch, no shorts; also tested the diodes, good. I've tested most of the resistors, good. I haven't tested all the caps yet but none seem to be leaky. That leaves the chip or the transistors from what I gather. But I am not to sure. I would love to play my original old pong system that I played back when I was 4 year old again. I also included a schematic of the c-100 to help you help me out...
