However, consider the fact that it takes five to twenty hours to generate each picture of this resoloution on a VAX 11/780 that has no other processes running. Now, who is going to be dumb enough to use a 32032 to do something like this? If it's the occasional frame once a month, I can see it. But nobody's going to do a large number of frames like this on a regualar basis. Keep in mind that the 32032 is a MICROprocesser. It's not made for huge jobs. However, if you insist on doing fifty or sixty frames, I'm sure that the time it takes to dump a frame to disk (a few seconds, at most) will be negligible compared to the CPU time (measured in *days*) that it will take to generate the image. ===================================================================== Curt Sampson ihnp4!alberta!jeff --------------------------------------------------------------------- "It looked like something resembling white marble, which was probably what is was: something resembling white marble."
