Logic bricks make me wonder if someone took enough time and made a big enough build using logic bricks to build an actual computer with all the computer parts. I wonder what the OS would be like on it, and I bet that it would lag the heck out of the game.
I've already downloaded the mod. Turns out there's an extension package which already has a full adder on a single 2x3 plate brick. I was busy making an adder in it, until i realized that it would be EXTREMELY difficult to space out all the components. Also, the components are extremely confusing, which means that to work with this mod you need to know exactly how the components work in real life in order to understand to which ports which wires connect to, ect.
Luckily i do :)
To understand how each of them components work i suggest taking a look at a program called Logisim. It's a logical circuit simulator, and hell people make real computers in that program.
