You can use the IMDU program (part of the ImageDisk package) to convert 
those files to a vanilla sector image.  From there, cpmtools is your 
friend for extracting the files.  IIRC, the BB used the same format as the 
Xerox 820 machines and they'll probably already be a useable diskdef.  If 
not, it's fairly straightforward to write one.
