Mego 2-XL (Version 2). The original 2-XL was manufactured by Mego Corporation from 1978 through 1981. Made of brown plastic with white plastic found on the anterior face of the robot. It had two red light bulbs for the eyes (version 1). These bulbs also flashed at moments while 8-track cartridge tape programs played. It had four red buttons on its stomach with designated options for answers to questions asked by the toy, such as "Question," "A or Yes Or True," "B or More Info," and "C or No or False”. The mold and look received a minor revision in 1980. The eye lights became red and responded to the voice. The flashing lights were also brighter, and the speaker in the back of the unit was changed from a hexagon shape to a more traditional round. The plastic had a glossier appearance. There was a modified version of 2-XL made just for schools with extra earphone jacks, specialty tapes for school curricula, and a teacher's manual to go with each educational tape.
