glass tty

glass tty: /glas T-T-Y/ or /glas ti'tee/ n. 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" (appendix A) for an
   interesting true story about a glass tty.
