(I know there are 256K pixels on a > 512x512 screen, but you get the idea.) With 8 bits per pixel you would also need 18-bit color registers. This won't work with the current 16 bit register size. A 7-plane mode would work if you had 5-bit video DAC's. In other words: planes registers bits/reg colors n 2^(n-2) (n-2)*3 2^((n-2)*3) 6 16 12 4096 7 32 15 32768 8 64 18 262144
