The first MSCP controller in the system should always live at address 17772150 in order to be bootable. Additional controllers must use the available floating address space. Additional controllers must also jumper W12 or W13 depending on the desired starting LUN (W12 for LUN 4, W13 for LUN 8). In a PDP11 system there must be no LUN conflicts.
