    Yes, this would be considered an ALU instead of a processor.

    plug 2 of the into each others input output

    Correct me if I'm wrong, but this appears to be an ALU, not a processor.

    it is a temp based cpu. 2+3 makes 5 on it

    when I do 1+1 it firsts outputs 1 then 1 again and then 2!

    hasnt worked out so well for me, not too familiar of which d pin is the 1st. even so ive never managed to get a correct calculation from this cpu. suggestion, use instant conductors for the pins instead of titanium, so that there arent any late signals

    @myself: an ALU just need NOR or NAND to be Turing-complete. So you can make a hella computer in TPT, but it's still going to be slooooow.

    Complex computers will not be possible in TPT untill logic gate elements are added. Logic gates today are just to small for any complex computers.
