2. The apparatus of claim 1 wherein the orientation of the first receptacle of the power cord terminal comprises the orientation of the second receptacle of the power cord terminal inverted 180 degrees.

3. The apparatus of claim 1 wherein the orientation of the first receptacle of the connector cord terminal comprises the orientation of the second receptacle of the connector cord terminal inverted 180 degrees.

4. The apparatus of claim 3 further comprising a flexible cord having a first end and a second end, the first end attached to a side wall of the connector cord terminal and the second end attached to a side wall of the housing.

5. The apparatus of claim 2 further comprising a flexible cord having a first end and a second end, the first end attached a side wall of the power cord terminal and the second end attached to the power plug.

6. The apparatus of claim 4 wherein the flexible cord forms a U-shaped curve and wherein the flexible cord does not extend beyond side walls of the first and second electronic modules.

7. The apparatus of claim 1 wherein the power cord terminal and the connector cord terminal are identical.

8. The apparatus of claim 1 wherein the power plug of the first end of the power cord includes a standard three prong plug.

9. The apparatus of claim 1 wherein the power source includes an AC outlet.

10. The apparatus of claim 1 wherein the power cord terminal is comprised of a rigid, insulative material.

11. The apparatus of claim 1 wherein the connector cord terminal is comprised of a rigid, insulative material.

12. The apparatus of claim 1 wherein the power cord is approximately 71/2 feet in length.

13. The apparatus of claim 1 wherein the connector cord is approximately 6 inches in length.

14. The apparatus of claim 1 wherein the first and second receptacles of the connector cord terminal each include openings for receiving a three prong plug, the openings of the first receptacle having a first orientation, the openings of the second receptacle having a second orientation which is different from the first orientation.

15. The apparatus of claim 14 wherein the first orientation is inverted 180 degrees from the second orientation.

16. An apparatus for electrically connecting a plurality of electronic modules comprising:

a plurality of vertically stacked electronic modules, each of the modules including an identically configured recessed power input plug, a power cord including first and second ends, the first end of the power cord including an integrally formed power plug for insertion into an AC outlet, the second end of the power cord including an integrally formed power cord terminal, the power cord terminal including first and second receptacles, the first receptacle of the power cord terminal engaged with a recessed power input plug of a first electronic module, a first connector cord including first and second ends, the first end of the first connector cord including an integrally formed plug recessed in a housing engaged with the second receptacle of the power cord terminal, the second end of the first connector cord including a first connector cord terminal, the first connector cord terminal including first and second receptacles, a flexible cord having a first end and a second end, the first end attached to a side wall of the housing and the second end attached to a side wall of the first connector cord terminal, the first receptacle of the first connector cord terminal engaged with a recessed power input plug of a second electronic module adjacent the first electronic module.

17. The apparatus of claim 16 wherein the first receptacle of the first connector cord terminal has an orientation which is different from an orientation of the second receptacle of the first connector cord terminal.

18.
