Okay, made the repairs from above, re-seated all chips and cleaned prongs, found one other problem which I also fixed in picture 1...
Picture 2 is the only date I could find on any chip/board. It's an Intel Chip dated 1977. I don't know if that's good or bad but it's something.
I replaced the capacitor at C34, the one that was blown completely away, with a best guess because I don't know what board it is.
On power on, it that capacitor gets very hot and smoked for a short time. (until I pulled the plug).
I don't know if I got the Cap right or not but at least its some progress. Obviously something still isn't right...
Pictures attached.
