I’m going to assume this isn’t supposed to look like this. Am I screwed?

Pulled this audio board out of my long-neglected Xybots machine, and I thought "something doesn't look right here."
Thoughts?

No Sir. I was referring to the lack of solder mask everywhere. It looks like acid damage, but there is nothing to leak acid in this machine. Why is the whole board not green like the back? There was no mouse house on top of it, though the inside of the cabinet smells that way. Do all the Atari audio boards of this era look like the mask has corroded off? This board was dirty when I removed it, but nothing flaked off when I washed and brushed it. 🤷🏻‍♂️
 
Atari didn't put mask on the top of a lot of arcade boards. Asteroids, Centipede, Missile Command off the top of my head.

Well, I'm used to that, but this just looked so spotty and "surface rusty" that I thought maybe something ate the poorly-applied mask off over the years. Oh well. Guess I'll run it and see what happens.

If you saw the deflection board in my 19v2000 you'd think that thing was pretty minty. Looks like it's decomposing but it works great :50:
 
Well this project hit a dead end after I posted this query. Many of the chips on the main board have terminally bad corrosion on one side, and legs are breaking off left and right. Both pokeys and most of the EPROMs are affected. Given that the parts cost and labor time involved in fixing all that FAR exceeds what I paid for the machine, I'm afraid this Xybots has run its course. Perhaps I could convert it into an impressive jukebox…
 
Looks like general corrosion.

What kind of humidity does this see?
 
A LOT until I obtained it. It was sitting in a non-climate-controlled building for decades with a hole in the roof.
Yep, there's the problem. You can recover it. It will take a lot of time.

That's pretty bad damage. I wonder if there was enough humidity at times that there was a dissimilar metal couple and galvanic corrosion?

Lead and Tin are adjacent in the galvanic series, and the solder (50-50 lead-tin solder) is actually LESS noble than either the Lead or the Tin. Copper on the other hand is far more noble, so if copper is in play with moisture, it could have driven this through porosity in the lead or tin plating of the copper traces.

got a G05 at work that looks straight out of a swamp. I didn't even bother doing anything with it. the other G05 was used as a donor to replace a V2000. lol

Please let me know if you want to sell the joysticks. Thanks.
 
They need a thorough cleaning. I disassembled one of them just to see how it was built. Even ordered new rubber donuts for them. Make me an offer, if you're in the continental U.S..
