Actually the 4 bit converter was intended as a volume control. It gets
multiplied by the 1-bit digital sound output. If you get the sound output
to be a constant, then you do effectively have the ability to do 4 bit
sampled sound using the volume control. When I was playing with my Atari800
I also realized that by combining channels to get the 16 bit divisor and
higher input clock you can actually produce a tone in the hundreds of
KHz. I don't know if you can get it quite onto the AM band, or if the
analog portion has the bandwidth. If so, you could broadcast your samples
on AM directly from the POKEY!!

Just HAD to put that one out there :-)
