Of course, I meant "file manager" in the OS-9 sense, not in the sense of 
a userland move-stuff-around utility, but of course the latter would be 
a fine thing as well.  I always thought gshell could have been a whole 
lot better.  And of course an 'mc'-style text-mode thing would be a lot 
easier on memory.  What I had in mind was something along the lines of 
RBF -- call it FBF, the FAT block file manager.  Device descriptors like 
c0 and m0 would specify whether we are talking about CoCo ('RS-DOS') or 
MS-DOS disks.  (256- or 512-byte sectors, what type of FAT, etc.)  Maybe 
the differences are too great to make it practical.

I always hated the RSDOS and PCDOS utilities.
