Good question.  Yes I believe so.  Thanks for the link with useful
conversation.  A year or two ago I made a cable back before I found this
nice DEC branded version so I went through the pin assignment fun then.

Update:  I now have both a working DL11-W (M7856) and an DL11 (M7800) who
connect to my terminal through the DEC cable with part number BC03L-10.  I
have loaded PDPGUI program so I can test things, etc.

Next - Get RT-11 running.  That's a whole other thread though.
