This is follow-up to the last PC XT clone motherboard repair video. (You should watch that one first, if you haven't seen it yet.)

After reading some really helpful comments, I went back to this board to see if I could find the problem. After some poking around, the issue was located and I then use the scope to see the problem in action!
