Hope you got a good deal. Now you must share your repair progress here :)

Water damage is a pita. Have a few damaged boards (not TT) and delamination is usually RIP.

Worst thing I have seen is battery leakage onto the board.

That dissolves tracks and continues to eat away along the tracks until neutralized by an acid wash.

Main culprits are Archimedes and Amiga 2000s, although beware ANYTHING that is battery backed and over 15 years old with the battery looming over the mainboard.

How the hell did this case get water damage this bad?!?

From the pictures it looks like the battery has leaked.

Very Bad !

Good thing is that the Matrix TC1208E Graphiccard works fine and is ok. HDD is faulty because the motor is faulty. I tested it not now but I think that the PowerSupply, Fastram and ST Ram board are ok ...

That's a leaked battery rather than rust, no?

I'd say that motherboard is a goner ...

That's not nearly as bad as I expected. It's totally fixable. Looks to be a REV.C maybe REV.A, can't say for sure without seeing the other side. But either one.

You gotta neutralize that crap and take care to clean the board in the proper way. Once it's clean it will look a lot better. Only then will we see the actual corrosion. Most of the crap is in the unpopulated area which is good.

I would have bought this had I seen these pictures but not for that price. This will definitely see action one day.

It has a PGA CPU on the Mainboard, not on a DaughterBoard and the 32Mhz Speeder Stuff also on the Mainboard.

So a REV.C. That's good.

So how do you feel about this Frank?
