The SCSI Zip drives do act as normal SCSI drives (though they have a limited
number of SCSI ids available. (5 & 6 if I remember correctly.) Later drives
may have this changed.)
The problems i am encountering are due to the _parellel_ version of the Zip
drive. (I bought it because I needed to be able to visit customer sites and
not all of them have SCSI.) The drivers fake a scsi port. (Some laptops
use a similar driver to attach hard drives to non-scsi systems.)
Maybe I will just get a Jaz drive and not worry about it...
