was is see link one of the last companies to make Mac OS X compatible PCI SCSI cards.
There may be boxes out there with the card.

I wanted my scsi Imacon scanner working on my 2010 macpro and tried eveything including this atto card. It cost me a lot of money and effort to find out that the best thing is to get an old g4 and it all works fine. Or, as I finally did, get a Ratoc scsi to firewire converter (around $300 nowadays) . It's working fine now with a g5 imac I had lying around.
Problems you will encounter if you try are:
-apple stopped supporting scsi somewhere along the road
-you need an old operating system (no later than snow leopard) to get the software for the scsi scanner working
-the oldest system you can use on a mac, is the system it came with
- the fact that it works, does not mean that it keeps on working tomorrow or next week
My advice is don't even think about it!
But my point in the earlier post was, that you should not go telling someone, who obviously knows nothing about these things, that it works, because if you get it to work, it is only under very special circumstances.
You could ie install snow leopard on a separate disc on your macpro, get a Ratoc converter and you have a good chance it works. But in real life there are a lot of problems if you want the rest of your computer working on a newer system. The SL system does not recognize the disks with the newer system, so try to startup your main disk

But it is getting a bit off topic I'm afraid.
