  that helps. The BC19S has a block near the BNC
connectors where you plug 
in
  the keyboard and mouse, it also has a screw sticking
out of the block, I 
think
  it is designed to screw into certain CRTs to hold the
block in place.
  
 Does it look just like this, but maybe shorter?

 How long is your BC19S?  I think the BC18Z I have is a -25 foot version, 
which
  is a bit longer than I need. 
The one I have is about 10 feet long, although I have not measured it.
