Yeah, you're right. Since most of the modern VGA-card has an S-video output, and almost all is bundled with s-video-composite cable, I mostly use the word of S-video for both.
@davewb : The a500 has Composite port. (Monochrome only) So if you have the same in your tv, or in your Video/DVD player
you can see, that is your a500 is working or not.
