GE 3XM3214
The GE 3XM3214 is a mini boombox with a 3-inch TV, AM/FM radio, and a microcassette player. It also features line-inputs. It takes 7 C-cell batteries. Most of the controls are hidden under the door on top. The images below show the model with an E suffix (3XM3214E). We do now know what, if any differences there are between the non suffix model or the E suffix model.
