Thanks for pointing that out. Which pins are you referring to? I just looked through my ATI VGAWonder manual and didn't see anything out of ordinary. I dug out my October 1990 issue of Radio Electronics and found the article on a device that converts NTSC->VGA from Harmonics Research in New Jersey (201) 652-3277. I decided to call them and was delighted to find that they also have a device that converts VGA->NTSC/S-Video for ~$120 (I don't remember the exact price) in kit form and $283 assembled. We will probably give this a shot. I also got this in mail: } Tim, I think we may be able to help you. We manufacture an SVGA board } that can provide an NTSC recordable output in all standard VGA modes } as well as several extended modes, including 640x480x256. } } Give us a call at (512) 346-5781 and ask for Carrie Cavanaugh.
