There the RGB etc. signals are digital and can be stored in a simple memory scheme for repeating the line. This is how the Princeton Graphics Scan DOubler board works on the PC giving a very nice looking 31.5 kHz scan rate. On the Amiga the video output is analog RGB, that's the only way you can get so many colors. So a scan doubler would have to have a method of storing a line in analog form. No easy matter. There is a digital RGB output port on the Amiga but I don't know if anyone uses it. If they did they would have to use a non-Amiga monitor and would lose the color range. - Mike Gingell ...decvax!mcnc!ecsvax!mjg
