I've been really busy this year. You know how it is. Life gets in the way sometimes. There seems to be a resurgence of interest in my project. I'll have to get my butt in gear and finish the next revision.
I tried to make it so that I only had one PCB board for all versions, but the combined footprint of mini DIN plus RCA jack seems to be more trouble than it's worth. For the next one, I'll make two versions. One with composite only and one with RGB. I'm also going to look into a two position slide switch rather than the three position. I think if I use the smaller switch, I might be able to make it fit without cutting the plastic.
