On the scale that ZIP Drives were produced, it's probably no coincidence that they were all basically SCSI with a Parallel port conversion capable controller was the path taken. Nor is it surprising that the parallel port version supported the Mac. There were Grappler/Hurdler cards for both the Apple II and NuBus Slots. I've got one of the parallel port NuBus Cards. If you weren't way across the pond, I'd love to get that ZIP to try on it.

When the IDE interface rolled out, HDD mfrs just started slapping different controller cards on SCSI Drives already in production. HDDs aren't natively SCSI like the ZIP, but generic in the sens that their I/O structure lent itself to either controller card. IIRC, MFM and RLL drives were a tad different, but things shook out quite nicely when IDE hit the streets on the same lane as SCSI.

Did the Parallel Port version support the Apple II? Such a solution would make for the second easiest of cross-platform solutions using a single drive. The SCSI/Parallel Port hybrid is news to me, that would be far and away the most simple of, single drive, cross-platform solutions.

Anybody have either of which that they'd like to unload here in the States? :?:
