I bought the PNP which is a total board replacement. Some are "plug ins" to existing sockets on an existing board in the engine. that's certainly going to be easiest if you have all the pins (which sort of intuitively roughly corresponds to the number of operator function codes). one of the above says 21 pin plug in. not sure of the other one.

i would say check their website and read carefully. They have a big "selector" and you can with some fiddling about figure out the model, the sounds on it and so on for the prime mover of interest.

i agree its a bit confusing to have the kinds and form factors, but they do provide with some elbow grease the info to ultimately figure it out.
