well here i have made an example of micro electronics in a nuclear power plant its very simple but cool https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=5586 I am also in a group with jalfor and dnerd making a computer i have made a binary hardwired compiler well i will when they get the ect done the alu is still a bit large. XD I have barely done anything complicated the best i have done is the gates and some other stuff well the harddrive but thats Bray i am working on my coding atm so not much is getting done :( EDIT: Surf I dont know how to do rom but you could do a decoder to function as it really i think decoders are better you can suit them to any task.
