Dan:
I don't believe that the 'L' series plug-ins lacked the coax connector in
the rear of the plug-in that are required to get the LO's to the "D"
connector on the rear of the mainframe. I've heard that it could be added
later without much trouble but I'd imagine that the connectors are next to
impossible to find.
