That should read "(video, color, sync)."  There is no sound information
carried on an NTSC signal.  There's enough stuff in there as it is (field
sync, line sync, color burst, video carrier, and even the black-and-white
video signal...).

: An Analog RGB monitor has 3 distinct video signals (red, green, blue) that
: form in various amounts to makes all colors.  Each signal is variable from
: 0-5V and there is one other signal (sync) which locks the picture.
: This type of monitor has increased bandwith (more pixels) than the
: composite monitor.

Sounds good.

: A digital RGB monitor has 5 digital signal lines (red, green, blue,
: intensity, and sync).  It can form only 16 colors (a combination of
: red, green, blue at low intesity for 8 and a combo of red, green, blue at
: high intensity for the other 8).  The digital RGB is not as good as analog
: RGB due to the fact that only 16 distinct colors are availiable, whereas
: the Analog RGB has an infinitely variable color palette.

Which, of course, brings up the question of why only Apple and Commodore
adopted the analog RGB standard while everyone else went TTL...
