I spent Saturday night playing around with hacktv and an original Thomson VideoCrypt decoder. Stupidly blew the TX amp in my HackRF during the process though.
I have a fairly large collection of Sky cards, I'm pretty sure I have every design that they issued publicly. With the official release from fsphil, I had two Sky issue 11 cards that work. One of them was actually my parents' card from around 1997. I've loads of issue 12 cards (the yellow ones) and none of them work. They sit on PLEASE WAIT but nothing happens.
With Captain Jack's fork, I experimented with the 09 mode. I have two 09 cards that work, but interestingly, I also have three issue 10 cards that work in this mode too. I wonder if the VBI data was extracted from a time when the transition period between 09 and 10 was taking place? The 09 cards also show the P0 T0 message when inserted.
For the laugh, I had an old Telecom Éireann CallCard, which was a type of prepaid phone card that was sold in Ireland in the 1990s which could be used in payphones. Putting this in the VideoCrypt decoder returns the message "50 TOKENS REMAINING". I'm surprised that it reads it at all.
