Driver for ATTO UL5D PCI-E SCSI card

I believe the latest driver is "osx_drv_epicu320_443" but I can't find a link to a download. Thanks

Mac Pro, 10.11

ATTO UL5D Express PCIe SCSI adapter card ATTOTech no longer supports this card, and more importantly, does not maintain a download of any drivers for it (let’s bring back the concept of “shame”). Does anyone out there have the last Apple driver made for it, specifically osx_drv_epicu320_443? No Mac Pro model that I own even recognizes that the card is installed in a PCIe slot, which is troubling. An old troubleshooting guide from ATTO suggests that it won’t show up without the driver loaded, which would be a surprise to me. Others have asked for this driver before, although with no forum response. Someone must have it, as an eight year old thread discussed how to make it work with Mavericks and Yosemite. Anyone?

SCSI cards are very hard to find drivers for these days, as most were developed prior the migration to Intel CPU Macs.

One resource which may still have record of where to find it is http://www.xlr8yourmac.com
