fame buffer redraw

Are there any TOPs that allow frame buffer redraw to be turned off ? Specific use is for a simple paint program . . . feedback works, but only for fairly slow input.

Thanks,
Jeff

I’m not sure I follow. Which frame buffer do you not want to redraw?

Hmmm, yeah, bit vague, sorry. What I’m wondering is if there’s any TOP functionality that emulates the old trick of turning of the main frame buffer redraw (back when there was just 1 display buffer), which was how feedback was done. It was also an easy way to make a simple paint program, which is my goal. I’ve created something using feedback with the final level TOP set to 1.0001, but when the brush moves fast a chain of dots are created rather than a smooth line.

Thanks,
Jeff
