I just yesterday started working on assembling an 11/05 S with a BK11-K
backplane.  At the moment I am working through the power regulators to make
sure everything is right before I install the boards.  I am assembling from
parts on hand but I do have the correct cards.  I have M7260/61 and 8K
Core, etc.    Just one 9 slot backplane.  Nice simple system.
