My version of a processor
It's not as compact as devast8a's but it's easier to follow what's happening (in my opinion). More for a 'how does this stuff work' rather than a 'how small can it be made'

Because everything is laid out and solid there are a lot of particles, this might slow down other computers (?) I'm new with this and not really sure...works 60fps on my machine

Addition works well, you just have to read the result from the RAM register C. Subtraction kinda works but only if instructions are put in the right order. Play with it if you'd like. Clear everything and then add a battery in the box marked Sub

The clock is there just for the hell of it...I think it works better to just spark the clock manually but it works with the actual clock.

Use batteries to set the inputs. The two 8-bit inputs for numbers and the 4-bit instruction input. There are some instructions that aren't used so go nuts with those. See the actual thing for the instructions as well as a sample program.

It only works if the heatsim is turned off.

So anyway, this is what I have. It's my first creation here so any constructive crit would be appreciated.

Thanks :] I could have merged the command and the data input but I ran out of space and panicked a little. Looking back I could have ran it differently and had more space to put the switching in. My design here is far from space efficient.

As for heat problems, when I enable the heat sim the spark won't jump from certain materials. It only happens on large scale stuff like this processor or if I copy-pasta the hell out of some component. The program doesn't slow down, it just stops working in that one regard. I couldn't figure out if it was just built up heat trapped because it happened even when the connections were heat-sunk with diamond. Any suggestions? Try enabling the heatsim and you'll see what happens (or maybe it won't happen for you and it's a problem on my end)

I played with your processor, very cool. It's neat to see how different people build the stuff entirely differently. I really like your input method and I somewhat wish I had gone that route rather than using a decoder. Anyway, it seemed like an adder/subtractor was the first thing that everyone makes with the electronics. What is the standard next step?
