AT&T introduced their Sceptre Videotex Terminal in Miami, Florida on October 30, 1983, thirteen years before WebTV was introduced. The Sceptre operated on the same principle as WebTV, i.e. the wireless keyboard-controlled system delivered news, weather, sports, stock reports, banking, shopping, email, and other information via a modem-equipped box attached to an ordinary television. Of course, the graphical web we have today didn't exist in 1983, so this information was all on-screen text called Videotex, a term that seems to have dropped out of the English vocabulary.

You may not be able to subscibe to the service, but it's a great piece of computing history.
This unit comes complete with the original box and hardware - NO manual.
