That should be done now.  Please confirm you're happy with the result.

Well, we don't specifically claim to emulate a CXA16.  If you can find 
documentation which describes how Qbus PDP11 or VAX can distinguish 
between this controller and a CXY08, then we can add support and thus
have to solve the problem of how many lines.  Otherwise, the existing
expression (Unibus ? 16 : 8) is sufficient in the current VH simulator.
