800k disk image of the original Iomega Zip Disk Install Disk drivers
for Zip disk drives v4.2 in a Stuffit archive. I've heard this one's
kinda hard to find, hope it helps someone.

The 1st download is a Disk Copy 4.2 image of the installer floppy
disk. The installer requires the Zip Tools disk to work. If anyone has
a physical copy of the Zip Tools Version 4.2 disk (including all the
extras), please make an image and upload it here so that we have a
historically correct set (for Macintosh at least).

For those who want to actually install the Iomega Zip 4.2 software to
use, a working install package can be found at [The Mac Driver
Museum][1].

Version 4.2 can be used to run a Zip drive on a MacPlus: a simple web
search will give you information on how to do this.

EDIT: Nothwistanding the above, the floppy install disk contains the
Iomega Driver and Iomega Guest which are actually sufficient to use
the Zip Drive.

Download #1 Disk image of install disk.
Download #2 Iomega Driver extension on its own.
Download #3 Epson Zip Tools 4.2 (includes DiskFit Direct v1.0, from
Dantz)

Compatibility
Architecture: 68k

Mac OS 6-8.6

mrdav: The Iomega Driver and Guest work with Mac OS 6.0.8 and Mac OS
7, whereas the Zip Tools need Mac OS 7 (adapted from the installation
guide)
