The Wonder wizard.

 

This is the " Wonder wizard " pong videogame system.This strange system made by General Home Products ( GHP ) in 1976 have the exact same bottom part as the original Odyssey even the battery part is the same.
Whay this is i dont know itīs a verry strange mix of
Magnavox systems ( the inside is from the Odyssey 300 )
but itīs not a system sold by
Magnavox.
