Unfortunately, it is not IOMEGA's fault.  You're laying the blame on the
wrong company, if my SCSI knowledge isn't too rusty.  On the SCSI spec, it
says that the host adapter should have the ability to provide TERMPOWER. 
So the Adaptec MiniSCSI adapters should be providing termination
power, and not the Zip drive.

Now, Adaptec might be very limited and constrainted when they made those
parallel-to-SCSI adapters.  There really isn't that much power to be drawn
from a single parallel port.  So they sacrificed one thing (TERMPOWER) for
another (portability).

Someone correct me if I am wrong.

 They will work, however, if (still
