Crumar Musical Instruments User Group.

Hello:  I am obviously a new member here.  I am bidding on an 
accordion that has a midi unit called  Crumar Nerve Center 50.  Does 
anyone know anything about "Nerve Center 50  by Crumar" 
I think that it is a pretty good but older musical/midi equipment but 
I can't find any information on the "Crumar Nerve Center 50"
Anything you could contribute would be appreciated.
