This is a beautiful piece of USA made vintage Toshiba merchandise from 1982, I used it sitting on the dashboard of my Volvo 264 GLE Diesel four door sedan in the eighties while sitting in bumper to bumper NY traffic commuting to work back and forth every day. There is an optional Toshiba BP 045 Battery Case that attached to the bottom of the unit, that I never owned, there are inputs for the AC cord, which I have, and a 12 volt power cord, to work off the car cigarette lighter. ( I do not have that 2nd adaptor, but it is a standard product to purchase). Good for tailgating, camping, commuting, workstation, small retail store, many uses and the fun of it being rare, vintage and so ahead of its time back then. K23Top
