How do you expect your rule to match these properties?
You say:
> SUBSYSTEMS=="scsi"
But it is 'SUBSYSTEM=="block"' instead.
You say:
> ATTR{model}=="ZIP 100"
But it is 'ATTRS{model}=="ZIP 100 "' instead.
And besides: you cannot mix properties of two different device sections. Have a
look at how to write udev rules[0] properly.
One rule which should work could look like this:
ATTRS{model}=="ZIP 100 ", ATTRS{vendor}=="IOMEGA ", SYMLINK+="zip"
