So in really short u want a decoder to detect what order a pair of pressure plates where pressed? (If its 1 then 2 or 2 then 1) but you need it to be small because you have 90 inputs and detecting each pattern is like (90!) Decoders. am I correct? In which case I'll see what I can do and try build one that is stackable and don't need 100 million other decoders, hopefully some other members might help out as well
