====== SABA DC5000 in Action ======

** Christian Berger **

Bildschirmtext (BTX) was an early online Service of the German postal service (Post). I will demonstrate a DC 5000 Terminal for this which was meant to be used with normal home TV sets. The vision was to bring a terminal into every home to allow everyone to use computers without having to maintain one.

You can get get more info on it in a Talk I held at the Hope 2020 https://archive.org/details/hopeconf2020/20200729_1800_Bildschirmtext.mp4
