The next step in the evolution.

I am done with the first chapter and now on the next. In chapter 2 I am going to build a 16 bit ALU along with the book but I am also going to make a 4 bit ALU and a 8 bit ALU. I am also going to try to make the 4 Bit ALU in real hardware and maybe the 8 bit. I will see how it goes and maybe draw the schematic and post it for the 4 bit ALU
