Hi all, I think I've *finally* got the display list concept. Of course I won't know for sure until I actually write something :-) Now I have a question about the DLI. In the MARIA doc it states... "One of the bits of a DLL entry tells MARIA to generate a Display List Interrupt (DLI) for that zone. The interrupt will actually occur following DMA on the last line of the PREVIOUS zone." Is it possible to have a DLI point to another DLL? From reading this it says it's limited to a scan line unless I'm reading it wrong. It would be nice to have a DLI spin off to another DLL so the screen could be split vertically with two "kernels" running. Take care, Dennis
