Re: A Cunning Plan
A bit like ceefax
That's quite stretching it.
The main difference is that Minitel is interactive: you can enter data into forms if they're present on a page, where ceefax is strictly one-way. Plus, while ceefax pages can contain links to other pages those can't load on demand; they only become available to you as that page appears in the data stream.
Maybe you were thinking of Viewdata?
