Television magazine published a "build your own" teletext decoder design during the mid-70s but in common with many designs of the period it could display pages in black and white only and didn't take full advantage of other new features introduced in the second version of the broadcast teletext specification (flashing and concealed characters).

This article indicates the "state of the art" for teletext decoder design at that time (June 1979) using discrete electronics. It was published by ETI over the July and August 1979 issues and is a complete "how to".

Mark Cook and Mike Brown have transcribed the articles onto the web, purely for its historical interest value.

Although the kits referred to in the article are no longer available it might well be possible to construct such a decoder today using the images and text shown here, we will accept no responsibility for the results, should anyone attempt it!
