Can you scan this card and the Xebec interfaces you have and post a
picture of them somewhere? I then might be able to tell you if you've got
a winning combination.

Ok, I just took stock of the hardware in my next room. I have a First
Class Peripherals Sider ][ hard drive (actually two) and for the first
time ever noticed that they have a Xebec label on the bottom, which I
guess means these are actually Xebec hard drives and First Class was the
name they sold hard drives under? Whatever.
Ok, so then I opened one up and noticed a Xebec PCB that is the same size
as a 5.25" drive, that contains among many other things a Z80, an 8502 and
a ROM with a Xebec label. The connector is 50 pins.
I then opened the Apple //e hood and the Xebec controller card also has 50
pins.
So I'm not familiar with the card you have at only 26 pins.

If you consider Xebec to be the standard then yes. I've never seen a hard
drive controller made by any company other than Xebec.
