Description

The Acorn Teletext Adapter receives its signal from a TV aerial and connects to the BBC Micro via the 1MHz Bus. The BBC Micro must have a Teletext ROM installed. Teletext is a system used to broadcast text using spare lines in a TV signal (see Wikipedia for a history of Teletext).

When the BBC Micro was launched, the BBC also used Teletext to broadcast software for people to download. When the UK digital switchover results in the Analogue TV service being turned off, it will no longer be a broadcast Teletext service in the UK and the Teletext Adapter will cease to be useful.
