I've been into arcade boards for about 3 years but have been into electronics for about 20 years I spent 13 of them as a television repair man, then went in to R&D for a audio company now im a electrician. But no matter what ive done i've always enjoyed anything coin-op. . I've been into nintendo repair latley and have gathered quite a collection of donkey kong repairs. Right now i have a galaxian pcb that seems to have quite the list of troubles. So if anyone has any Problems i'll be glad to help.
