Construction - Power, Clock Source, and Reset
Separating Tracks and Establishing the Power Supply Rails
The main step in wiring the power distribution lines was important to do at the beginning because there will not be another chance to carry it out once the signaling wires are laid. There are two things to take note of in the last picture on this page. The first is that wires distributing power to the 4-bit ALUs are incorrect in that their connection is suppose to be to the pins in the center of the chip. The second is that my soldering iron's heating element was dying and thus insufficient heat was being generated for the job as can be seen by the partially heated joints.
Soldered IC sockets and lines for the cuts
Cuts were made and a few resistors were soldered to the backside (no room on top)

Power distribution branches from the main supply rails
Clock Signal Distribution and Reset
The clock signal is carried by the green wires while the reset signal is carried by the blue wires. In future pages, however, I will use blue to signify other signals as well because I just happened to have a lot of wire in that color.
This type of wiring topology is only the beginning
