The final dimensions of the unit were 7.5 inches high, 4.5 inches 
wide, and 1.875 inches deep. 
Weight is around 3 pounds (with batteries)

The lower wood grain panel opens to reveal the 3 AA batteries that power the video screen.

A 9-volt battery powers the Atari circuitry. Below it is the vintage-looking silver & black colored Volume Control.

An original Atari power supply cable can be plugged into the AUX Input to avoid using the 9 volt. The video display still runs off the 3 AA's even when the AUX Input is used. However, since the 9 volt battery runs out three times faster than the AA's, it's worth using. I hope to improve battery time in future versions.
