by a faulty ULA chip, which have been out of production for about 25 years, and are
very difficult to find.

The ULA controls the Display and Tape I/O (input/output), this chip normally runs hotter than it was designed to do, and so fails much sooner than most of the other components. This ULA was also only ever produced for the ZX81, and went out of production about 25 years ago, and so is not only the most likely component to fail, but is the hardest component to source.
