[TUHS] VFS prior to 1984

[Anthony Martin]

The only other prior art I know of is

  Toda, I. W. A. O. (1980). DCNA higher level protocols. IEEE
  Transactions on Communications, 28(4), 575-584.

wherein they state the following:

  A virtual file system, from the viewpoint of application programs on a
  computer, models the file system functions of other computers. This is
  done in the same way as with virtual terminals, a virtual file system
  consists of a UPP having virtual files (VF), and a UCP which executes
  virtual file system protocols.

I'd be interested if you find anything earlier.
