I think I finished writing the CPU up. Missing are the ROM and RAM.

But I only tested load and addition commands yet. TODO: Test every instruction

See:

What can be seen here?
load 5 into register 0
load 9 into register 1
load 2a into register 3 (Output address)
Add reg 0 and 1, save into reg 2

Display result (0x000e) at address (0x002a)

Looking good.
