Notes:
- COPROFS documented as &C0-&C4, but actually will use as many as its
  workspace allows, up to &C0-&CC.
- RetroClinic RAMFS uses &60-&64, Acacia RAMFS uses &60-&65.
- Very early versions of HADFS used &05-&0A and &85-&8A to read/write control
  information, later versions use &19-&1D to access this control information.
- IOFS in BBCTerm uses handles &80-&9F but its OSFSC entry reports that it uses
  &80-&A0. IOFS also incorrectly reports its filing system number as &00.
- LanManFS clashes with NFS/ANFS, but the hardware cannot be present at the
  same time and the LanManFS Ethernet card plugs into the Econet card sockets.
