They mentioned a BBC MICRO, but I've never used one of those. I have no
idea as to what MODE 7 is or whether it is specific to any given hardware.

I could read CNN's Teletext without any problems. I'm only concerned BBC
and ITV anyway. As for designing a font, I guess I need to use VioSetFont
and VioGetFont, but I can find no examples of these anywhere...

I somehow suspect that Philips would have even less of a clue about
VioSetFont than I have.
