The simplest approach (as suggested by Fred) would be to use 22Disk to 
simply read files out of the CP/M filesystem.  If you are dealing with a 
non-standard format that is not in the default database, you would need to 
purchase a registered copy that has tools for building new definitions.

Alternately, you can use ImageDisk to capture an IMD file, then convert to 
a sector image with the accompanying IMDU utility.  From there, use 
'cpmtools' under Linux to read out the files. It is relatively 
straightforward to define new disk formats for cpmtools, although you will 
certainly have some experimentation ahead of you.
