"you just have to change planes" I'm not sure what this is asking. In Mode X the pixels are stored in memory in a weird way, yes. pixel one on the screen is in memory location 0, plane 0. pixel two on the screen is in memory location 0, plane 1. pixel three on the screen is in memory location 0, plane 2. pixel four on the screen is in memory location 0, plane 3. sorry.. ii I should have numbered pixels from 0 also. Since the latches are set for all four planes from one read, you can just set the VGA to take all of its data from the latches and none from the CPU, and then it just takes one read and one write and viola.. four pixels. anyway, it IS confusing. a point of terminology.. are the bitplanes 0-3 or 1-4? or does it matter? daiel reznick reznick@acf3.nyu.edu
