I bought the IOMEGA ZIP 100 drive. I use it with the PC, but not with my Mac Performa 5200 running OS 8.5.1. I downloaded the IOMEGA ZIP driver 4.3. When I plug in the scsi into the Mac my display is shattered. What can I do in order to run the ZIP drive?

I bought the IOMEGA ZIP 100 drive. I can use it with the PC, but not with my Mac Performa 5200 running OS 8.5.1. I downloaded the IOMEGA ZIP driver 4.3. for the Macintosh. When I try to install the driver, an error message occurs, which tells me to plug in the ZIP drive. When I plug in the scsi into the Mac my display is shattered and the cursor freezes. What can I do in order to run the ZIP drive?

Performa 5200-OTHER, Mac OS 8.6 or Earlier

This is one of the weaknesses of SCSI which probably spelled its demise in the consumer market. You had to turn on the SCSI devices that are external and wait for them to spin up before you booted the computer. Otherwise it wouldn't terminate right. As long as they are the sole SCSI device, having a SCSI ID on the dip switch of 1 or greater should help. If there are internal SCSI drives, make it 2 or more. SCSI Probe is a utility that can tell you who has which SCSI ID before you connect the Zip drive. Iomega has on its CD some tools for using its Zip drive which may help.

When I plug in the scsi into the Mac my display is shattered and the cursor freezes. As long as the scsi is plugged the Mac does not work at all. After the scsi is unplugged the Mac can be rebooted easily. What can I do in order to install the ZIP 100 driver 4.3. on the mac?

You have the PC-only version of the Zip 100 drive, that's designed to connect to a parallel port. Unfortunately, the DB-25 parallel port is identical to the DB-25 SCSI port, which causes confusion for the end-user. That's why the 5200 locked up, when you connected the Zip drive to it. The two buses aren't compatible. The SCSI version of the Zip drive differs from the parallel port version by the presence of two slide switches on the rear. One was designed to terminate the device, while the other set the SCSI address to either 5 or 6. Additionally, the SCSI version has a pair of female DB-25 ports, while the parallel port version has a male and female DB-25 port on the rear. For use with any Mac, you'd need a Zip drive that connects via SCSI or USB, depending on the age of the computer and its available interfaces or expansion options.

Thank you Jeff for the right answer: "You have the PC-only version of the Zip 100 drive."

Do I have to buy a ZIP 100 drive, that is working with both the Windows XP and the MAC? Or is there another simple solution to transfer a big 5 MB Word file from to the MAC 5200 to the Windows XP? The space of the floppy 3,5" is limited to 1,4 MB.

Kind regards frm

You might find file compression software such as Stuffit might reduce it below 1.4 MB if it is mostly text. Of course you would have to format the floppy to DOS format for use with the PC. I recall an extension called DOS Mounter that enabled older Macs to use DOS formatted discs.


If it won't squeeze down you may also find a segmentation tool that will split up the file, then re-jon together the segments on the other end. Again the problem isn't the tool as such but finding one that works on both Mac and PC.
