	We have a number of DEC VT240 terminals that have been very 
unreliable.  They die (regularly) with "NVR Error - 10" errors on powerup.
This indicates that the non-volatile memory that stores set-up information 
has problems.  The local terminal repair services fix this by replacing 
the terminal controller board --- typically charging $350+ for the board
exchange and another $100 for labor.  Needless to say, there costs are 
not justified when I can replace the terminal with a non-DEC equivalent 
for not much more money.

	Has anyone found a cheap repair for these VT240 terminals?  Are
there less expensive sources for the controller board exchange?  Does 
this NVR error indicate a replacable component on the controller board?
Any ideas would be much appreciated.

Thanks,
