Secret Teletext Pages, Clockcracker and more...

[devolution]

I'm hoping some people on here can enlighten me on some Teletext issues.

I discovered quite a few years ago about the 'test' pages they have on
Teletext, like P399 on Channel 4, P699 on ITV etc. I read on a Teletext
website tonight that they are known as 'Clock Cracker' pages. Anyone know
how they got that name?

Also, if you Press the Fastext buttons on P399 on C4 you can get to some odd
pages dealing with PDC (I do know what that is) and other stuff.

I am wondering if anyone knows of any other 'secret' - well hidden or
engineering or test pages on Teletext in the UK? Perhaps someone with a PC
Teletext card has browsed through and seen some interesting stuff? I do know
that the pages can be comprised in a hexadecimal format. Eg. P1DA, P3AA etc.

I have seen a page on ITV (also seen it on the Teletext on some satellite
channels), which gives a kind of list of Channels and a 'Queue' number
beside them. What is this for?

Also, does anyone remember about Page 777 on ITV in the late eighties /
early ninties? What was it for and what did it do. It might have been
something to do with Prestel or Viewdata, but can't remember.

TIA.

Bamboozle (P152 on C4) has hexadecimal tag pages that can normally only be
accessed through fastext buttons.

CNN (satellite) uses hex page numbers for some sort of subscription service.

There used to be some sort of premium phone rate system on ITV (was this
P777?) whereby you phoned up and were given a sub page number or something.
A Philips "easytext" set could capture these without loss, although why
anyone would pay for them...
