Mmmm, and has a wiggle on Channel 4 shown up anything?

The first is interesting. I had no idea they were not only restricted in 
what lines they could transmit upon (logical enough) but also what 
magazine they could use!

The licensee may use magazines 1, 2, 3, 4 and 5 on Channel 3 and 
magazines 1, 2, 4, 5 and 6 on Channel 4/S4C. Within any page, packets 
with Y = 0 to 29 are available to the public teletext licensee. The main 
introductory page will be on page 100.

The last line is an interesting one. I thought C4's index was on p400?


Best wishes,

Rick.
