When I was a child, I had a Commodore 64 always connected to a TV via the RF Out. I remember that when running a BASIC program, there were certain noises to be heard. Especially when a longer
FOR loop was run, a breathing noise which was initially rising then falling again could be heard. What is the cause for this? Do CPU and the RF modulator interfere in some way here? Also, the classic noises during flash loads - do they have the same reason?
I noticed that the term flash load is actually not common. I mean loaders (usually used on the tape drive) which showed flashing stripes on the screen during loading.
