   DSSI is *not* a predecessor to SCSI.  Modern SCSI has surpassed it in 
terms of transfer speed, but DSSI does things that SCSI has never, and 
will never do.

   Picture logging into a disk drive and running a process on it o 
generate seek length distribution histograms in ASCII graphics.

   But more to the point...I think I have a KFQSA here somewhere, but 
I'm in the middle of moving and I have no idea where it might be.  I 
will look for it.

   Why is adding SCSI disks to the QBus SCSI controller ugly and
