The Risc PC didn't have SCSI support IIRC, and I've an odd idea the A540
may have come with a SCSI podule?, have you any idea who manufactured
the SCSI podule this drive it would have been connected to?  Acorn did
one, Oak did another, don't know if there are more.  (Mine was Oak.)

When you say it's mountable under Linux, does that mean

    mount -o loop mnt acorn.img

just works or did you have to specify an offset into the image?

At first glance it looks a bit odd.  If Linux handles it then I guess
the drive's particular partition scheme, there were various, must be in
