Quoted from ChrisHibler:
The corrosion looks like it's limited to the parts and didn't invade the traces. I've never seen a board with so much corrosion limited to parts only.
Still...if it were my board, I'd take a shot at it. But, I repair boards all the time, and if I don't get all the corrosion and it comes back, not big deal for a board in my game. I wouldn't take it on for a customer. Too much time, cost, and risk of corrosion returning.
PS - I like your shoes too.

I think this means the corrosion happened recently. I have seen some leaks caught within a month or so of the puke end up looking worse than it is. More typically the battery damage happened years ago and the corrosion goes deep down.
I would pass on fixing that board. Hard to say how it is going to look once you pull those PIAs on components. SYS 11 boards seem to be a nightmare if the batteries leak. They dont hold up to an abrasive cleaning like the earlier generations did.
