BTW, are you building your own plug with the ~820 ohm resister? For now I just have something kludged up with dangling wires attached to a resister and no proper pins and plug housing. When I looked for the correct plug housing in the past it seemed that part was no longer available for purchase that I could find. Have you found a proper plug housing to use for this?
I have one of these 12944-60002 cables and can only see the AMP brand on the connectors and no part number: http://www.computerhistory.org/collections/catalog/102728386 -Glen
