Perhaps what you're seeing is the switch box? They were all largely
similar.
Likewise, the original Coco did NOT have an external connector for
composite video. If you wanted composite video, you needed to open the
case, and solder up an additional connector.
The picture(s) in the manuals were of a switchbox, which converted from
coax RF to 75-ohm archaic antenna connector. RS made a big deal about
using such a switchbox, so that the TV could still be used as a TV, AND so
that the computer output never got connected in parallel, providing it
with an antenna.
