This is becoming increasingly important as viruses spread... obviously on
the GS you can kill it from the control panel (although an intelligent virus
can turn it back on...), but the //e does create difficulties.  It may be
possible to wire something into the interface slot (hold a certain line low,
etc.), but this sounds a little dangerous.

Note that it *is* possible to disallow write access to a ProDOS file (incl
subdirectories; not sure about volumes).  Check out the change permissions
command in Davex (mine is aliased to chmod; not sure what it should be...)
