Who gives a flying fuck about implementation the guy is smart. But thats why I sorta dislike this server, everyone only cares about how good something looks and how compact/fast it looks. No one cares about architecture. And even with a 70 tick clock speed and not compact what so ever. Im going to call this the best computer on the server.

I Never Said That I Only Care For Compact/Fast Designs... And That I Don't Care About The Architecture... I Just Said That He Uses Ripple Carry Adders...(Which By How Slow The Thing Is.... Adding CLE Adders Or IC Adders Won't Really Help...)

You see im an old school redstoner, i dont use all the latest stuff like CLE or cut carry or flood carry. Eventually I will learn these new ways and probably make a new CPU with them or something but for now, ripple carry works and its nice and so thats why i use it.

I really appreciate that! I would like to see your von neumann as I have never really seen one other than mine.

Ok cut I was explaining this on the server but you had to leave so I can tell you now. Basicly the clock is a 7 second clock, each clock cycle does 1 step of the stepper. But an instruction like add takes more then 1 step to complete. Example: 1st step - load value B into the TEMP register 2nd step - load value a into the alu and the temp reg into the alu and add them together 3rd step - save the result into another register As there is only 1 bus every command must be executed like this, in a series of steps. In each step any register can be read from and saved to but as there is only 1 bus you can only do 1 register at a time, get it? But, as we want to access the next location in ram to get the next instruction after the current add instruction is finished we want to do a little addition. Now this takes another 3 steps. There is also one final step that resets the stepper back to step 1. In total that = 7 steps every instruction will need to do no matter what it is. So it takes 7 clock cycles to complete one instruction cycle. I know this is very slow but as its von neumann it needs to be like this.
