Oh nice. I knew that semidisk had made a QX-10 variant, but i had never seen one before. I own an IBM-PC and S-100 variant of this card.
One of my QX-10 disks I've collected had a copy of the semidisk driver program and part of the source code, It was missing the actual QX-10 specific driver code though. Hopefully you can get a dump of the disk released online. It would also be nice if you could get some scans of the manual released as well.
