It was my first system, bought with paper route money. General electric quadraphonic w/8track. Got it at a discount at the company store because my dad worked there. I'm sure my dad regretted driving down to pick it up. Van Halen, Deep Purple and of course Pink Ployd. It had a joystick balance control which could be used to make the helicopter fly around the room.Eddie is one of those guys who will always be young talented and so damn cool in our minds. Think I'll go crank up eruption and annoy my kids
