That may be so but putting it on a board to accept a IDE drive is far 
more useful to us that run hardware.
Why IDE, It can use CF and I also have a large supply of drives from 
20-512mb.   Fortunately I have a
large supply of MFM drives and two SCSI controllers for the larger 
supply of SCSI drives.  However, I
feel I'm the exception and many Qbus users are not so fortunate.

Where is the source code to for that? That is the drive side of that.
