ALU Schematics

These are the schematics I used during construction of the arithmetic-logic unit (ALU) board. They are simple scans of hand-drawn diagrams. The originals are pencil on notebook paper, and may be a little hard to read in places, especially if I erased something and drew it again. I may replace these with proper graphics drawings, but for now this is all I have.
