Take a look at ftp://bitsavers.informatik.uni-stuttgart.de/pdf/dilog/2120-0147_DU686_ESDI_MSCP_Nov87.pdf <ftp://bitsavers.informatik.uni-stuttgart.de/pdf/dilog/2120-0147_DU686_ESDI_MSCP_Nov87.pdf>
Its only Unibus type device I have seen a Dilog Manual for. It might help you sort out the Unibus addressing
