El Condor Pasa
If I'm not mistaken, EagleSoft did this in one of their intro's as well.
Imagine your surprise, when suddenly your drive begins to "hum" a catchy tune. First, you think it's loading something, then you think it's an error, and eventually you discern the tune.
But - indeed - I guess it's not really good for your drive motor...
Btw, does anyone have an idea how this is done, technically speaking? Is it possible to search for specific sectors on the disk through some intuition (or rather disk) library commands?
