Hi Smiler,
sorry to say that from the photos it's impossible to make any conclusion other than it looks like it's been butchered. I would need a circuit diagram to know what the extra inputs/outputs are for.
I have no idea of what you are capable of doing in respect to electronics. I've sent you an email so I can set up contact with you, please inform me as to your capabilities. In return I'll send you a set of diagrams that we can work from.
One thing that is important is to inform me as to the condition of the reverse side of the printed circuit board, i.e. are any of the tracks burned out, cut through, or moded. If yes take a photo of the damage and send it to me.
The reason I suggest using email contact is I don't sit at the computer all day, with an email it will shorten the turnaround time.
Cheers. KarG.
