This could be a consideration. This falls into the current Amiga video discussion, try this idea on for size. A third party developer designs a video card that fits into one of the Amiga slots based on their favorite graphics coprocessor, Intuition is modified slightly so that all graphic operations can either execute using the standard Amiga graphics hardware *OR* they can use a jump table to jump to routines in autoconfig memory occupied by this hypothetical card. It also seemed to me that such a card would invariably be loaded with it's own dedicated graphics memory, freeing up chip ram and reducing bus contention. This seems as though this shouldn't be THAT difficult, however I just got my first Amiga a few days ago, so I have no REAL idea of the problems involved. The Macintosh uses a similar scheme unless I'm mistaken? On a similar note, I heard a rumor, I think it was printed in Amiga World, that Pixar, who did a very impressive graphics card for the Mac, was working on a similar card for the Amiga. Has anyone else heard this rumor, can anyone lend creedance to it one way or the other? -- George
