I still would love to work with you on the component video board. I really want to be able to take your component video schematic once it's available and design a PCB with the same footprint and mounting design as 5-11under's board. That way anyone with 5-11under's board can easily upgrade to the new board (me included). But then it'd be great to finalise the CV palette project beforehand and so I have made a start on writing this up and will send it to you for review (if that's okay) when I have something worthwhile for you to look at. It's been almost a year but I stumbled on this as I am trying to achieve the essentially the same thing: I'm making a TMS9128 video card for my homebrew computer and I want YPbPr output. I am currently using the Tatung Einstein circuit just so I can work on software while I figure out the hardware side (I did try and build the hackaday RGB circuit but tapping into YUV before converting to RGB but I didn't get it to work. I probably messed up wiring somewhere.) Would love to know if there is progress here and to offer breadboarding/prototyping support or even just to look over what you have in an unfinished state. I guess it's probably best to just start with the final v2 board design of the TMS-RGB and tap into the YPbPr lines and leave off the big expensive RGB converter? Also seems like I would want the THS7314 as there is no need for the 4th (sync) signal. Quote Link to comment Share on other sites More sharing options...
