ISTR that teletext is not that common in the NTSC world (though there's
another system called closed-captioning, used for encoding text for the
hearing-impaired, which is sometimes used on laserdiscs as well), but just
about every PAL station has got teletext pages, which are accompanied by a
time signal. At least one of my VTRs may be set to fetch its time from any
preset station. And since teletext decoders must be one of the most common
homebrew projects of all time, adapting one of those could be another idea.

I can't understand ANY current MICROS~1 product names!
Are they now created with a random word generator?
What is the intent behind the name "Visual Studio" for their compiler suite?
What is "Interdev"?
Why is the Virus Transfer Protocol product named "Outlook"?
