@biffzinker @Robert B I absolutely ADORE Iomega ZIP drives! Bought mine back in 2001, and then bought yet another ZIP100 unit few months later (both internal, ATAPI models) and used ZIP diskettes as USB flash drives, before the flash drives were even invented of course
The main purpose was to be able to transfer files from one system to another (had two machines, Pentium II & Pentium 4), and/or to backup important stuff. Obviously, it didn't take long for Iomega drives to become obsolete & I barely used them since then. To make things even worse, just after I bought the Iomega drive(s), I also installed ethernet card(s), making the entire file-transfer concept completely unnecessary.
But nowdays, I LOVE these things! I got several Iomega ZIP100 disks, some of which are still sealed up & never used before!
So whenever I come across Iomega drive unit, I pick it up & mount it inside an old rig. Got quite a few of them actually, including ZIP250 on several systems but since I don't have any 250 disks, I'm just using them as ZIP100. From what I can count right now, in front of me I got 5 ATAPI ZIP100/250 drives, with additional one inside that Visualize P-Class system which doesn't work and ONE more that was taken out from yet another P-Class system & is currently just sitting on my shelf. So, that's 7 ATAPI units in total, and also got the external one, identical to yours
@Robert B. Parallel port, from what I can tell it was never used before, but it was somewhat damaged when I picked it up, so I had to take it apart & glue that top "window" back into the frame. Just curious, does your unit lights up with green LED as soon as you plug in the power supply?
