 (Sharp PC-7100)
  Notice how the handle can slide towards the back
so it's off-center?
 Notice the little metal inserts along the top edge of the back?  There's 
 a
  printer (I've only got one) that attaches to
the back for portability.   
 Didn't the IBM Portable (or convertible...whatever) do that?
