16bit personality modules for wide-SCSI drives - the 8bit version was
BA35X-MG. This means you should have 2 68 pin plugs on there; make sure you
use the one down the side of the module rather than on the end. The end one
was for cascading.

I never had to change the switches on those; typically they were left unless
you were cascading shelves. I can check some -MH modules in the office
tomorrow if you're still stuck then.

You've got a cascaded pair there then.

Nope, purely personality modules to support 16bit disks.

Correct; the SCSI ID is based on shelf number and which port on the host
machine you're plugged into.

No need - it's all hardware based - plug disks into shelf, plug shelf into
host machine and use disks :)
