[QUOTE="Channel Hopper, post: 57124, member: 175144"] The Zener diode was a modification made to the standalone decoder boxes (ferguson SVA1 slopers) . BSKYB in the day could authorise a 30V (I think) voltage pulse on one pin of the card to render it useless, the diode preventied the spike from doing the damage, thereby extending the life of doctored and alternative decryption cards [/QUOTE]
