Can you find an old computer running DOS? Seriously, the PC speaker 
has always been a problem for Windows. In order to produce sounds, you 
need the timer chip, which is being used for other things. That's why 
the WinAPI doesn't expose much of an interface for it (Beep() and 
MessageBeep(0xFFFF), and those grundgingly). What you want to do was 
commonplace 10 or 20 years ago, but the PC has moved on.
