You can cable anything you like. If that will work is another question ;-)
Seriously, the OP should just a VCR as a receiver/demodulator and feed the
(C)VBS signal into an appropriate monitor (some modern flat panel displays
have an RCA and/or S-Video input; or just use a video monitor, or
better: just buy (or get for free) an old TV).
The whole discussion is on the niveau of saying "I don't need electricity,
but I want to use my electric toaster. What can I do?".
I am inlcuned to agree wit hthat. The OP doesn't want to modify his CoCo
(that's up to him, and he doesn;t have a TV. But a thing that receives
and demodulates VHF TV signals amd then displays them has the
functionality of a TV, and might as well be called one. And that's what
he actualyl needs. Whether it's a TV set (sold as such), a VCR tuner
followed by a composite monitor,m or a TV card in a PC.
BTW: NTSC is a colour encoding system and has nothing
to do with TV
channel frequencies.
I thought 'NTSC' was 'National Television Standerds Committee'. If so, I
would be suprised if the only thing they ever standardised was a colour
encoding system.
