Remember glass tty
glass tty Technical Terms
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.
