All you'd need is a Centronics 50 female connector for ribbon cable and a backplane plate for said connector. Then you'll have an actual, for real, non-Apple-borked, SCSI port just like those found on the backs of correctly implemented SCSI peripherals.
We'll forgive IOMEGA for using those Dumb@$$ DB-25 connectors because they did passthrough and switchable termination/partial ID selection on the back of a tiny box! Apple, on the other hand, had no excuse whatsoever, there was plenty of room on the back of even Compact Macs to do a proper job.
Apple finally came close to a proper SCSI implementation with those HUMONGOUS, Horribly Unwieldly, still Dumb@$$ PB SCSI Cables . . .
. . . but we won't go there!

p.s. When I couldn't find my HD50 <-> DB-25 SCSI Cable to use a ZIP on my QS2000 when I first got it, I rigged up just such a setup. I pulled it out a couple of days ago, when I decided to retire the ZIP Drive in favor of USB Card Readers on all my PCI/USB Compatible Macs. If you'd like I can take and post a piccie of it for you.
