Yes, it will work.  You need to add the following to your
/etc/format.dat file:

# Iomega ZIP 100 drive
disk_type = "Zip 100" \
        : ctlr = SCSI \
        : ncyl = 2406 : acyl = 2 : pcyl = 2408 : nhead = 2 \
        : nsect= 40 : rpm = 3600 : bpt = 20480
partition = "Zip 100" \
        : disk = "Zip 100" : ctlr = SCSI \
        : 2 = 0, 192480 \
        : 2 = 0, 1159168

# Iomega Jaz drive
disk_type = "Jaz 1GB" \
        : ctlr = SCSI \
        : ncyl = 1018 : acyl = 2 : pcyl = 1020 : nhead = 64 \
        : nsect = 32 : rpm = 3600 : bpt = 16384
partition = "Jaz 1GB" \
        : disk= "Jaz 1GB" : ctlr = SCSI \
        : 2 = 0, 2084864

It will treat your ZIP disk as another hard drive.  You need
to do the following:

1. Set your SCSI ID on your ZIP/JAZ drive.
2. Do a `boot -r` at the PROM level.
3. Add your device to the /etc/vfstab.
4. Create your mount point.
5. Run `newfs /dev/rdsk/cxtxdxsx` to create new filesystem.
6. Run `mountall`.

Not at all.  If you are running SUNOS 4.1.X, the /etc/format.dat
config above is slightly different.
