Darn - someone offered me two of those drives a couple of weeks ago. I
passed on them because I figured they'd be no use whatsoever for
anything any more! Of course obtaining media would have been
interesting...

I'm lost. The Adaptec board is a bridge between SCSI and ST506, so it
doesn't help for connecting a SCSI device directly to the Acorn SCSI
controller. From memory ST506 drives are completely dumb too; the
controller defines where boundaries between sectors are, not the drive -
so the controller can use whatever numbers of sectors per track it wants
and do translation in software.

I'm pretty sure I've got the Adaptec spec document somewhere, and the
Xebec equivalent. I've certainly got the Omti one. (paper copies though,
not scans) 

cheers
