Oops, sorry. I misread that.

You are correct. Generally the Xebec interfaces were used with the Sider
hard drives (at least those are the only drives I've ever seen them
used with) and they came with utilities on floppies for partitioning and
formatting the drive.

I don't think this is SASI since the actual hard drive is a ST-225 or
equivalent. More like MFM. I don't think I have the pinout, but then my
Sider manuals are stored away somewhere, and I don't know that they would
necessarily have any technical info for the Xebec card.

Are you wanting to use it to hook a hard drive up to your Apple ][?
