With the speed of todays PCs it ought to be possible to simply synthesize the video signal in real time using a program combining brute force, data reuse, double buffering and table lookups. Then the video generation exercise is reduced to finding a way of converting this stream of 5.5 million bytes per second into an analog signal. That might mean convincing a video card into lending us its D/A converter via DMA in some fashion. Maybe another forum member has a better idea of accomplishing this.
Just a thought...

Yes I agree with Frank.
The question is who is first on the marked. The low cost aurora or the
PC solution?
