I've got an old vt100 clone (with a manual!) and it, too, has some NVR for
  saving the set-up settings.  The NVR is some kind of programmable ROM with
  a limited number of erase/program cycles.  The manual warns that since the
  the NVR can only be written to 10^5 times or so, the user should not put
  the terminal into a repetitive NVR test mode (which erases and rewrites the
  NVR over and over and over again.)

So, if you're still getting an NVR error now, even after saving new set-up
  settings (Have you done this?  Cntrl-s does it on my terminal.) then chances
  are that your NVR has been used up, one way or another.

This shouldn't hurt the terminal, except for making it a pain to start up.
  Maybe the NVR can be replaced, if that is the problem.
