OK, then it sounds like it is just a funky way to use one connector
in place of two, which means each side is one end of the cable. 
Good trick.

I make up cables all the time, so that should not be too difficult
to do in this case.

Now, the problem then becomes to find one of those 100 pin mini-dual-inline
or whatever the heck they are idc connectors.   Anyone have a source or
part number for those?   If it is something relatively available, I can
probably get my parts-house friend to track it down.  If it is a totally
wierd DECism, or it take special press dies, then that may not be easy to do.

Any pointers/suggestions  appreciated.
