I just re read my previous message and realized that I am indeed wrong. I went through this same dilemma - the VGA's ALU (Arithmetic Logic Unit) is pretty useless, because it only works when 1) the latches are primed, and 2) on data coming FROM the cpu, which means at most two bytes at a time, and it also means that you CAN'T use the latches to copy from off screen display memory in Mode X, IF you want to use the ALU. daniel reznick reznick@acf3.nyu.edu
