Stack processors have long fascinated me, although I have never worked with one. Many not-so-experienced electronics enthusiasts however fail to realize how much effect temperature has on things. This fellow had a good debugging technique, an idea of what to investigate and a plan for how to go about it, and it paid off. As he points out, there are so many things that simulators and other tools just won't deliver.
