glass tty - Free On-line Dictionary of Computing (26 May 2007) :

  glass tty
  
     /glas T-T-Y/ or /glas ti'tee/ A terminal that has a display
     screen but which, because of hardware or software limitations,
     behaves like a teletype or some other printing terminal,
     thereby combining the disadvantages of both: like a printing
     terminal, it can't do fancy display hacks, and like a display
     terminal, it doesn't produce hard copy.  An example is the
     early "dumb" version of Lear-Siegler ADM 3 (without cursor
     control).  See tube, tty; compare dumb terminal, smart terminal
     .  See "TV Typewriters" for an interesting true
     story about a glass tty.
