When I said "comes with" I meant that it should be somewhere on the MacOS installation disks and is either an installation option or automatic if a zip drive is present and possibly automatic even without one, I forget.
Since you have 4.2 test the SCSI Zip with it first under System 7. Then, go look at your 9.1 and 9.2.2 extensions folders. If the Iomega Driver extension is already there, you should be good to go. If not, the question is how to extract one from the installation tome files of 9.x...
Perhaps the easiest way is to have a working SCSI Zip powered up for a newer Mac to recognize during a clean install of 9.2.2 and with luck it will do the right thing and put Iomega Driver version 6.0.8 into your new extensions folder. It's probably on the installation disk but hidden somewhere in a tome. Once you have one copy you can just make floppy transfer copies for earlier machines. I think due to a non-clean reinstallation regression accident I have Iomega Driver 6.0.6 from an earlier 9.1 installation installed on a PB1400c machine now running MacOS 8.6 and it works with my SCSI Zip. And I do not think it was downloaded from the net, but either got there from the initial install of 9.0.4 or the upgrade to 9.1 installation step, with a Zip drive possibly connected during the install for other software installations.
I forget the details but I determined I will have nothing to do with bloated IomegaWare. Just the driver extension is all you need, and if you find a version that you like just extract it alone from the IomegaWare file collection.
Don't remember from where I did the W98 download, and it could have been the browsing while locating the download that infected my system, who knows? In any case I've only seen this just once in many years of surfing, and now prefer to surf on Macs only. My Windows machines now get pressed into service for three instances: 1. When I can't get an important page or video to load on any browser on my Macs; 2. When I need to configure a WiFi device that comes with configuration software, non browser type, running on PCs only. 3. When I need to help someone with a Windows issue (I was Mac only until several years ago when I met a ladyfriend with a PC and some computer difficulties...).
