Q1 Modules

The Q1 is comprised of modules, each on a 13x25 cm board with 40-pin connectors. Here's a detailed look at each module.

Adder 8-bit full adder with carry in and carry out. For now the carry in will be tied to ground since the Q1 doesn't make use of it. Also note that I goofed when wiring up the socket: GND and Vcc are in the wrong places and the order of the bits is backwards.
