Nils,

I was hoping to do an 80 column version eventually, but I was basically going to duplicate the existing ram circuits (odd and even) as my colour ram and map them into $8800-8FFF. So basically the CRTC controller would read all 4  video ram blocks at once. I'm not sure I understand how dual-port ram would work in this situation.
