48 PROBLEM INVESTIGATION ARCHIVE

During his career with ICL, Brian Parker progressed from being an ordinary support engineer into a very experienced diagnostician. He was the sort of man any team of engineers would send for when faced with a particularly obscure bug, when it was not clear whether the problem lay in hardware, software, or the interaction between them both. He became especially expert in the use of the logic analyser, a magnificent diagnostic tool for those who could apply it. This section of the archive records his notes of the years when he and the logic analyser flew around the world in response to many varied distress calls. It thus provides a useful overview of the problems that affected computer users during the period in question, and illustrates how they were overcome by hard work, methodology and brilliant technical insight.
