Spliting a DEC BA350

Why yes you can. I've got the shelf manual and I'll type in the description:
         Turn off the shelf
         Remove the blowers
         Discharge any static buildup
         Make sure the SHELF_OK jumpers are installed
          correctly on either the backplane or on both the
          terminator boarrd and the jumper board as
          described in Chapter 2
         Install the BA35X-MB terminator board in the backplane
          connector behind slot 5
         Install the unused BA35X-MC jumper board in the backplane
          connector behind slot 1
         Connect the SCSI cable for device addresses 0,2,4 to the JA1
          connector
         Connect the SCSI cable for device addresses 1,3,5, and 6 to
          the JB1 connector.
         Replace the blowers
         Connect the power and verify that all devices are active

So it basically looks like you swap the terminator and the jumper boards
and then you get two busses, one with three devices and one with four
devices on it.
