Hi
Is that a qr code on that chip. Scan it who knows. Seems it's the only chip that can possibly hold the data on that board. Nothing under the big capacitor?

Nothing under the cap. The qr code is not etched good on the ic, can't read... I'll try to "enhance" it, maybe I can get my camera to read it
