I don't think so. Not only is this not documented in the manual, the lines aren't complete. There tend to be missing pixels; sometimes there are only a few pixels in a line. But, the lines are always horizontal, and typically occur every 1/4 to 1/6 or so of the vertical span, but don't seem to have any correlation with the actual vertical scale divisions. I'm wondering if the rams are suffering from pattern sensitivity failures. This used to be a reasonably common problem where writing to one address would also write to bits in other RAM rows (or columns, depending upon the ram design).

The dots are actually in memory. If I plot the graph, they show up in the plot also. Bill Ezell ---------- They said 'Windows or better' so I used Linux.

If the vertical retrace signal lasts for five horizontal scan line times, you w ould see five lines of pseudo video garbage during the vertical retrace. You mi ght only see the video garbage if the average amplitude of the video signal exce eded some threshold (which apparently occurs when the graph exceeds a certain si ze). Try displaying one of those wordy help screens or a display with "bold" values e nabled and see if the problem appears there. ---------------------------------------- _________________________________________________________________ Stay up to date on your PC, the Web, and your mobile phone with Windows Live.
