Hi. I have an Amiga 2000 and have become of late entranced by the abilities of the Copper for mid-Screen changes. The RKMs give a very general overview of Copper Lists. What they do not detail is using them for Interlaced displays. I am using the CINIT, CWAIT, CMOVE and CEND macros, but have not figured out how to do two separate lists … one for the even lines and one for the odd lines. The Hardware manual says something about setting an interrupt to the 68000 just after the first line of the display. Which interrupt and is that the first line of the even or odd or what??? Any information would be greatly appreciated. Code to this effect will get you a FREE t-shirt (a used one, of course) :). Thanx, Ray
