I tried upgrade your RAM 256x8 , because You don`t use a blue channel I was thing if I combine to two RGB I can use this to make another space to save information , so I made it but when I was test it I found a small mistake XD if I try to save data on blue channels I clear previous data on R nad G data slots , now I must add flip flop before RGB to save information on n Address add new information and save them , meybe I can use 1 less RGB screen but I must add 96 gates
This picture show You what I tried to do XP
