  Yes.  It replaces one of the main power supplies and includes a batter that
looks like a 'mini' AS/400 but weighs as much as a full sized one.  It is used 
back up the Main Memory in case of an unexpected power failure.

You should be able to find them used quite reasonably I would think.

  I believe that Controller 2 port 0 adddress 0 can be used for some things,
possibly even a system console during manual IPL but only if controller 1 has
completely failed.
