In this video I design and build the circuit to add a Palette to my VGA circuit, together with the DAC’s from the last video forming what in modern terminology would be called a RAMDAC.
This video ended up being much longer than I like main channel videos to be. I can’t really cut a video a video like this down the middle as I like to bring chunk of work to a conclusion. I will try to break work chunks down a bit more in future to avoid big ones like this. It was several videos worth of work at all stages.
There is no Schematic inset for this video, I did record it but I couldn’t get it to fit onto the screen without obscuring important work or scaling it to the point of uselessness. I may release a rough cut on the extras channel or add it to the pcb design when I get to it.
