require a tv?
If you're plugging the composite monitor into the RCA plug on the back of
the C64 you're not going to have much luck. That's the RF output. The
composite video is, if I remember correctly, on pin 4 of the AV DIN socket.
The C64 does not have an internal speaker. Sound is modulated on the RF if
you connect it to a TV, otherwise it's present on pin 3 of the AV DIN
connector. Either way, ^G does *not* give you a beep on a C64. To get
sound out of it you need to resort to POKEing (I can't remember exactly
where you need to POKE, but I'm sure someone else on the list can).
