That is good to know.  I have only used the RK11-D, but I have an
RK11-C in need of cleaning and testing that I've never used.  My goal
is to eventually reunite it with the PDP-11/20 it came with (sadly,
the RK05-F that was part of the set was tossed 35 years ago, but I do
have more than one RK05-J, and an abundance of 12-sector packs).
