Okay I've got it - looks like volume_open() currently gets confused when
trying to open a volume where the block size is not 512 bytes (in the
case of your CD image it is 4096 bytes). I have now implemented a basic
dir word (patch to follow shortly) which gives the following output
against your image:

Note that we don't (yet) do autolocation of partitions which is why the
cd:2 notation is needed to manually point towards the second partition
on the CD. Please test and let me know how you get on with your original
Apple CD.
ATB,
Mark.
