This Nord Lead 3 has been sitting in a corner for a few years now.  It was abandoned by a tech that was down the hall after the client didn’t want to pay to ship it to a Nord service center for repair.  But that was a few years ago!  Now it’s possible to get Nord parts from third parties like Syntaur!  So for 20$ in parts ( a new data encoder ) and an hour of work this Nord is Back To Life!
