It will work in a Q22 backplane providing you remove two links, which
otherwise cause the RLV11 to use BC1/BD1 for "other than BDAL18/19". It
has to be a straight backplane, with CD-interconnect, of course.
Even then, it only does 18-bit DMA, so whether it's useful depends on the
O/S -- RSX11 and Unix manage fine, but I don't know about RT-11.
