First question is: since the DL10 is a DMA device for a handful of PDP11s,
what is intended at the other (unibus) end of it?

I have found that

  http://bitsavers.trailing-edge.com/pdf/dec/pdp10/periph/MP00068_DN87_Universal_Comm_System_Front_End_Jan76.pdf

contains the engineering drawings for the DL10.

Also, the tops-10 source file D85INT.MAC (from the unsmon directory)
contains the driver for it.

If the idea is to get more terminal lines, maybe a DC10 scanner would
be an easier starting point.
