Louis, I use a Zip drive with an Apple High Speed SCSI card.  It works
fine IF you have another hard disk drive in the SCSI chain.  The other
SCSI hard drive needs to be there to provide termination power.

There is no need to modify the SCSI card (unless you have a tech
around to help).  You can solve the problem by just adding another
hard disk drive to the SCSI chain.

The Mac tools provided by Iomega will NOT partition the drive.  IF you
add a second hard disk to provide termination power, Advanced Disk
Utilities WILL partition the drive.

After adding the second hard disk to the chain, run Advanced Disk
Utilities to partition the disk, then format it.

If you want to set up a cross platform Mac/GS HFS Zip disk, you'll
also need the GenEx program.  This is only needed if you want to
read GS Zip disks on a Mac.  If you don't need Mac readability,
ADU alone will get your Zip disks up and running on the GS.  This
GenEx can be found on DejaNews and, reportedly, it has been
uploaded to the ground ftp server last month.

You need to repartition the Zip disks with Advanced Disk Utilities (found
on one of the System 6.0.1 disks).  Or....just buy PC rather than Mac
formatted Zip disks and reformat them as a big HFS volume from the
Finder.  PC formatted Zip disks do not have the driver info that causes
the phantom partitions on the GS.

Modem programs like ProTERM or Spectrum can use port 2 set to
"Your Card," so just plug the SCSI card in there....

Put a second hard disk drive (non-Zip) on the SCSI chain to provide
termination power, then partition the drive as you like with Advanced
Disk Utilities.  IF you want HFS partitions to be readable on Macintosh,
also download the GenEx program from DejaNews (it was posted to
comp.binaries.apple2 a few weeks ago) or ground (from cba2, it was
copied to ground last month).  GenEx is NOT needed if you don't
need to make the GS disks Mac readable.  Its purpose is to make
Zip disks that can be read on both GS and Macintosh.
