Yep, that's how it worked. With the A1300 Genlock, color 0 was replaced with
the external video source. This created an external video backdrop that other
graphic data could be placed onto (such as winddows, etc.). Makes the special
effect used in news broadcasts of overlaying a still photo above the announcer's
shoulder simple.

With the genlock, I used to run my laser-disk player output into the genlock and
watch Star Wars while I wote my programs :-)
