Troy,
Not sure if this qualifies but the color bars and DuMont color test pattern off screen images on my web page were taken off the internet. The pictures were fed from my WEBTV box to the antenna imput on the CT-100. WEBTV is designed to provide internet access through your regular tv set and seems to work fine with vintage tube sets. My page was also constructed through WEBTV.
