From p. 237 of "Mapping the Atari" (XL/XE edition): Here are the pinouts on the 800 and XL/XE's monitor jack: 1 - Composite luminance 2 - Ground 3 - Audio output 4 - Composite video 5 - Composite chroma Looking at the back of the 800, the pins are arranged like this (pretend the V shape below is really a semicircle): 3 1 5 4 2 My 800XL feeds the composite video input of my TV just fine using pin 3 for audio and pin 4 for the video. Hope this helps.
