Thank you Doug.

I did what you sugessted and it works fine.  I will reconfigure my scsi
busses so that all the 25 pin scsi devices are on the same controller with
no other devices.

I suppose the reason I was having problems is that there is no termination
on the pins that arn't used in the 25 pin cables.  Should have thought of
that myself!
