Hi, it can be a bit of a minefield as there are 3 different series of cards. Your Majik should be early type 1 mono but according to the link I'm including mounting plates are required and Rare.
I've just completed going active with Keilidh's.Any other questions I'll try to answer given my slightly limited knowledge.
