Re: AdLib GOLD clone is now a reality

While I'm here... would anyone happen to have a dump of the firmware? I have an original GOLD, and the firmware went bad. I've ordered some replacement chips... but, I need a clean dump to reflash. Hoping someone can help me out! Have you tried the process to reset the control chip? That can get …
