[Coco] precision soldering skill

[T. Franklin]

That's actually not uncommon. The boards were wave soldered (not soldered by hand). Sometimes the solder puddle which is actively moving will push the chips out of their position. It's not a problem if the board works. It's obviously worked for many years. I've seen this many times in my business and never gave it a second thought.

Someone told me once... "PC Boards are not sacred". Meaning, fixing a board with a wire or seeing this type of anomaly doesn't affect anything. However, I would like to add that this statement was made before the advent of surface mount and clock frequencies above 1 Ghz where PCB layouts effect performance.
