That's wiring that IBM provides, and if a customer monkeyed with it that would 
void the warranty. The board under discussion for the 407 is the customers' 
responsibility and most shops wired multiple boards for different purposes, 
e.g., 80-80 listing, specific reports.

Subject: Re: my new z114

On all of my machines, and likely most of the machines IBM made, there
is an interlock that prevents changing the patchboard in any way.
There is a complex hinge arrangement that closes the door before any
connections are made, basically. Sure, a Sawzall would solve that, but
that is not provided in many CE kits.
