I remember in the Really Early days of Satellite TV, one station had an amazing feature,
early Interactive...think had, scrolling list on screen, with a code for each video, you rang system
Dialled Number (using Touch tone, MF4 as BT calls it) and it put your video request, into playlist
(course lots of request for suggestive tracks)... was like a sort of, Satellite Video Jukebox

Ahh...memories of Early Sky Decoder boxes, where the Access card was Erased, (when it ran out)
with an off air signal, to put higher volts onto the Card, So what was done, Zener diode on Card Pin
and you had an Everlasting Sky card.

BT had to scrap all its Early PhoneCard Phoneboxs, where Laser in Phonebox Deleted credits on card.
Someone in Ireland discovered, that if you sprayed card with Hair Spray, that...
it stopped Phonebox deleting credits...once again, High Tech defeated by something simple
