Hmm, I'd forgotten they did RLL ones too - were they the 7xxx series? I'm 
pretty sure all 5xxx boards are interchangeable anyway (subject to them 
providing the required interfaces), and I *think* they're supposed to be 
compatible with an earlier non-5xxx board.

I've had various systems using the 5xxx boards, but I don't think I've ever 
run across any of the others fitted to anything.
