RB: that circuit board looks like it was run hard and put away wet...or it really was in some water at one time in its life for sure.

Thirty+ years of dust combined with the camera flash will do that.
Yeah, I can see that now. At first it looked like corrosion from sitting in water for a while. I've seen boards like that, and usually they don't work either.

EZdays, I had to "clean" up some alarm system boards that had been exposed to more than just a little moisture, mostly had to pull some micro chips out of their sockets and clean the crud from the sockets, sometimes commercial/industrial electronics just need to be cleaned to function again.
