VGA and CVBS are both analogue signals and, providing they are all there (Red, Green, Blue, Hsync, Vsync), you are unlikely to damage anything by connecting them like for like. However, your chances of getting a usable signal are not good. For a start you'll probably be restricted to 640x480 modes (at the maximum) from the CMM as otherwise I doubt if it will be able to synch. That will largely depend on the monitor's capabilities. Additionally the signal levels could be widely different.
VGA in general isn't suitable for broadcast / combined video situations. You can get VGA to combined video and VGA to RGB adaptors, but you will still find them very restrictive in what VGA formats they can handle. The picture quality is usually pretty poor too.
Your monitor should be fine for any of the original home computers that produce combined video or RGB outputs. Even those that use an RF modulator might be ok if you can tap the video signal off at the modulator input.
