The manual actually specifies a "color or TTL monochrome monitor" and
indicates that by "color" it means RGB.

In the setup screens the monitor choices are "color or composite monitor
(640 x 200) and "TTL monochrome monitor (720 x 350)."

My assumption is that RGB means CGA.  Is this correct?

At any rate, it looks to me that you need to feed the video from the PC into
the Trackstar via the patch cable in order to make the system work with one
monitor, either composite, TTL Monochrome or RGB (whatever RGB means).
