Well, I figured out how to add the drive and it was pretty
straight-forward.  I had been worried about how the 6000 would
determine the size of the disk, but it seemed to figure it out
somehow (yes, this is my first SCSI-using machine).  I now have
a partition with 1019904 KB (987728 free).

This is where I'm turning my attention now.

I reiterate the above!!
