Vintage IBM PC Keyboard. Was stored in garage in arizona for decades, at some point the styrofoam melted a bit. This can be easily removed, but since it is vintage I didn\'t want to try and do any cleaning or restoration ( I dunno, maybe like guitars it is considered \"Mojo\" and by cleaning it I\'ll wreck its value lol ) .Untested, but will accept returns if keyboard is DOA ( buyer to pay return ship ).
