For those of you going to the live Digitiser (this weekend?) or love teletext in general, I've made and maintain a teletext simulator online that features posts from Digitiser 2000 blog, game charts, Turner the Worm and Bamboozle.
You can navigate by keying in the page numbers or clicking the fasttext links at the bottom of the page. The site isn't quite mobile friendly atm and that will be looked into when I add a few more features to it.
Help and info can be found on page 102 and page 101 gives some contents.
