It is actually fascinating to think that it would have been possible to have an Amiga with software selectable RGB/yuv mode.
Yes, i know however seem that HAM should be in YUV mode with RGB output (i.e. YUV color space conversion on silicone).
Currently i investigating new vidiot capable to do regular RGB + YPbPr directly (same Amiga output as usual, sync on green etc) with digital control and perhaps some uC (XMOS?) on board to do extra things.
(To be honest it is quite tempting to place 3x32kB 8bit SRAM chips from old PC cache to have huge CLUT - controlling this from Copper/CPU and for example XMOS uC may be a nice thing - AGA already have similar feature and allow to put CLUT index in digital way).
