Yes, Steve, it CAN be done, and HAS in fact been done.  I have several pro-
grams on my 800 that play snatches of digitized music through the TV (monitor)
speaker: the Kinks' "You Really Got Me" (sic), and Huey Lewis' "Back In Time",
to name just two.  The resolution is pretty limited (a scale of 0-15), which 
results in severe audio "clipping" (i.e. non-linearity, i.e. "staticky" or 
"noisy" sound), but there's no difficulty in identifying what is being played.

I, too, would be interested in a reference to the magazine article that inspi-
red the original poster; i.e. if I can digitize at home with simple electronic
components, I'd love to know how!
