[Coco] CoCo 3 RGB to SCART to HDMI update

[Barry Nelson]

I found a site to host my project information for this so schematics and photos are now available at this link: https://hackaday.io/project/7366-coco-3-rgb-to-scart-to-hdmi-cable
For anyone who has not seen my earlier posts, this is a very low cost (all parts including the SCART converter are less than $60 total) and effective way for a CoCo 3 to display hi-resolution RGB video on a modern HDMI TV. The video quality is very good, there is a photo of the 80 column screen on the web site.
