Summary: 


It's not just old computers that make recognizable noises. The speaker in my
IBM PC will pick up on cyclic bus activity and I found I could tell when my
thesis project program (numerical stuff) moved from one section of the 
solution to another. The pitch of a quiet hum on the speaker would change.

Before I figured it out there were a few late nights that I thought 
I was going insane!
