Back in the early days of digital computers, engineers would often
troubleshoot hardware by writing "musical software." Portable AM radios would be used as "sniffers" in circuit
areas where tubes and/or relays would be turning on and off with rhythms that were determined by the test
software. If the chosen familiar tune did not sound as it should, then the problem could be deduced to be
associated with that area of the processor known to be controlled by the program.
