[Coco] For those of you following the RGB2VGA FPGA

[Luis Antoniosi (CoCoDemus)]

You can buy one for 80 dollars.

But I'm not aiming any production batch or commercial product. What I
wanted to do is to master the technology and not be slave of any other
device. Also I want to make a VGA converter for the coco2.

It will be hard to get the full coco3 color spectrum but I would be very
happy If I could remove most of the noise. What I know now from where is it
coming.
