Buckle:
A scheme, using data buried into the video signal was used in Germany.
During theTV broadcast you could see the data as white stripes in the
upper left corner.
A small circuit was used to filter out the data and feed it into the
RS232 port.
I do not remember the exact name of the scheme , German readers can
probably expand on this.
Needless to say that only computer related broadcasts used this
scheme...
Another deadend : Elektor magazine used singles (45 rpm vinyl records)
to distribute software for their SC/MP system..

There were
discussions on the list years ago about programs being
sent out
over the radio as in the UK so you would plug your radio output into
your
computer's cassette input to receive the program: mass software
distribution!
This was also done on Sunday afternoons in the mid 80's by a local rock
station, KZOK in Seattle, WA. The broadcast was 300 baud and you just
hooked your modem to your radio.
