As somebody already said, the Amiga's sound and video come from a set of
memory labelled 'chip RAM' which varies from 512K to two megs depending on
which model you have. This approach had advantages and disadvantages compared
to the dedicated DOC and Mega2/VGC sets of RAM on the GS motherboard.

ROM 03 has 64K of DOC RAM, sorry. This was a false rumor back when the 03
was first coming out.
