16 bit minecraft cpu performs ADD and SUBTRACT HD

I have made a significant amount of progress since my last video on this little project of mine, my cpu can now perform add, subtract (sometimes), xor, xnor, and, nand, or, nor, shift left, rotate left, shift right and rotate right, as well as all of the memory/display functions outlined in my last video. Next I must build some comparators and implement conditional branching, see you next week :) btw found out who came up with insta-ripple-carry, check out his channel :) http://www.youtube.com/user/ohmgane3sha Follow me on twitter for daily updates on my builds/projects! https://twitter.com/101m4n
