I am trying to connect a tszo7 tape drive to my VAXstation 3100 through the external scsi port. It looks like a normal 68port scsi port. I have a some cables lying around that seem to convert the 50 pin scsi on the tape drive to the 68 pin scsi that I need, but when I connect everything up all I see is pkb0 has 84 errors. Any ideas about how to go about getting this tape drive to work?
